ALL ABOUT HYBRID CONCRETE CONSTRUCTION
ALL ABOUT HYBRID CONCRETE CONSTRUCTION
What is Hybrid Concrete Construction?
    This method basically involves integration of precast concrete & cast in situ concrete to gain advantage from their diverse intrinsic qualities. The speed, accuracy, and high quality finishing of precast concrete is combined with flexible and economical in situ concrete to produce buildable, simple, yet competitive structures. The construction companies, by employing this construction method, are able to deliver the client a better value product. Increased off-site manufacture, faster and safer construction, and steady performance benefits both the clients and the contractors.
      Precast and in situ concrete are used together in several different ways to expand the design horizons for engineers, architects, and contractors. Both these elements can work independently in combination. Moreover, a structure may comprise both precast and cast in-situ concrete working together, compositely. There are numerous types of hybrid precast and cast in-situ systems among with some are widely used.
        Advantages of Using Hybrid Concrete Construction
          • Lower cost of construction Although the cost of building’s structural frame represents only 10 percent on the total project cost, the materials used for the frame have significant consequences for the following processes. Hybrid concrete construction offers great quality, speed, and reduced overall cost on a project. The use of concrete has many additional benefits in estimating the whole-life costs as well. For example, due to the thermal mass of concrete, energy demands in heating and cooling buildings can be moderated. This factor is important to the building owners, residents, and PFI operators.
            • Buildability (or Constructability) Hybrid concrete construction is used where it is most appropriate. By doing so, construction processes become relatively simple and rational. The use of precast and cast in situ concrete encourages the decisions regarding design and construction to be resolved at the design stage.
                Using this construction method also means that a certain percentage of the structural frame is being manufactured by a skilled labour force in a weatherproof factory, which results in faster and better quality construction.
                • Increased Safety During Construction A high percentage of work for hybrid concrete construction is carried out in a precast factory. The use of this method on site helps ensure that all the safety plans are drafted on the merits of individual projects. Hybrid concrete construction can also reduce the chances for accidents by providing work platforms on less cluttered sites.
                  • High Sustainability of Hybrid Concrete This type of construction allows to exploit the thermal mass of concrete by uncovering the soffit of precast concrete slabs. This energy storage capacity of the structure can help control temperatures in naturally ventilated, low-energy buildings. The shape and finish of the exposed concrete units also have the ability to reduce noise levels and even the distribution of lightening.
                      In today’s time, the operational energy of building is far more than that used during its construction, but in case of concrete buildings this might not hold true. It is because concrete buildings use thermal mass which can reduce energy consumption by minimizing the need for air-conditioning. Due to this reason, hybrid concrete construction is the best choice if you want to build an energy-efficient structure.
                      Structural Actions of Hybrid Concrete Construction
                        • Independent Action: It involves precast cladding that adorns in-situ framed buildings. The complicated portions of a structure usually lend themselves to in-situ construction whereas simple and repetitive sections may lend themselves to precast concrete construction.
                        • Combined Action: In this case precast units replace the in-situ elements directly. For example, hollow core floor units or stair flights within in-situ frames.
                        • Composite Action: It involves in-situ concrete toppings that are added to precast concrete floors for additional stiffness, strength, and robustness.

                        ALL YOU NEED TO KNOW ABOUT FLAT SLAB CONSTRUCTION

                        What is flat slab construction?

                          Flat slab construction method basically involves reinforcing concrete slab supported by concrete columns directly without any use of beams. This system is usually defined as a single-sided or double-sided support system with the entire load of slab being placed on supporting columns and a square shaped slab known as drop panels.
                            These drop panels play a major role in this construction method as they expand the sturdiness and capacity of the flooring system below the vertical loads and in this ways boost the cost effectiveness of construction. Generally, the height of drop panels is almost two times the height of the slab.
                              Flat slabs are suitable for most of the construction, especially for asymmetrical column layouts like ramps and curved shaped floors etc. There are several advantages of using flat slabs like flexibility in design layout, flat soffit, and depth solution. Although building flat slabs can be a bit costly but it gives architects and engineers immense freedom in designing. The advantages of flat slabs do not end at layout and design efficacy, they also help the construction teams by easing off installation process and saving considerable amount of construction time.

                                Types of Flat Slab Construction

                                  There are four major types of flat slab construction:
                                    • Simple flat slab construction
                                    • Flat slab construction with column heads
                                    • Flat slab construction with drop panels
                                    • Flat slab construction with both column heads and drop panels

                                      Uses of Column Heads in Flat Slab Construction

                                        • They increase the sheer strength of flat slabs.
                                        • They reduce the moment in flat slabs by reducing effective or clear span.

                                          Uses of Drop Panels in Flat Slab Construction

                                          • They increase the absolute strength of the slabs.
                                          • They increase the negative moment capacity of the slabs.
                                          • They stiffen the slabs and thus reduce deflection.

                                          Advantages of Flat Slab Construction

                                          There are several advantages of flat slabs, including:
                                          • It is a known fact that flab slabs without the use of drop panels can be manufactured in very less time as the framework of structure is diminished and simplified. Therefore, in such a case, the construction time is significantly reduced.
                                          • Flat slab construction can significantly reduce floor-to-floor height especially in cases where deep false ceiling is absent. It is because flat slab construction does not restrict the placement of horizontal partitions and services. This can be very beneficial in terms of reduced cladding expense and pre-fab services.
                                          • In case the client wants to make changes in the interior plans and use the accommodation according to his changing needs, flat slab construction is the best choice as it offers flexibility in terms of design and layout. This flexibility is mainly possible due to square lattice and absence of beam that makes allocation of partitions and channelling of services difficult.

                                          Types of Flat Slab Design

                                          Several methods and processes are involved in the designing the flat slabs and assessing these slabs in flexures. These methods include:
                                          • The empirical method: This method is usually used for designing smaller frames.
                                          • The sub-frame method: This method is usually used to design irregular frames. Their designs are conceptualized by using appropriate software. However, using sub-frame methods for very complex designs can be very costly.
                                          • The yield line method: This is the most cost effective method that is best suited for homogenous installation of reinforcements. A detailed visualization and thorough examination of cracking and deflection is needed since this method utilizes only collapse mechanism.
                                          • Finite-element analysis: Application of this method is very advantageous in case of structures that have floor with irregular supports, bear heavy loads, or have large openings. Finite-element analysis can also be used to calculate cracked width and deflections.

                                          3 Ways Advanced Robotics Will Affect the Construction Industry in 2020
                                          Despite all the recent technological innovations, construction industry still relies on many manual labour processes, which are the basis for several major series of operations or tasks. Many believe that the productivity and efficiency of the construction industry has still not met its true potential and has a long way to go.
                                            However, certain technologies are being developed and implemented in the construction processes that will play a major role in shaping the future of this industry. Among these innovations, advanced robotics have the potential to replace or considerably improve the existing construction processes, making them more accurate as well as more efficient. But unfortunately, in the present time, robots are not playing any major role in the construction industry. This is true for all commercial, residential as well as renovation-based projects. This role of robots, however, is expected to change in near future and it will lead to an incredible transformative experience that will reshape the entire industry.
                                              Considering all these expected changes, we’ve listed down five ways in which advanced robotics will affect the construction processes in the coming year:
                                                1. Reduced Operating Costs
                                                  By implementing advanced robotics and automation in construction processes, the overall operating costs will reduce leading to a considerable cut in overall project cost. The related tools and equipment also tends to be more precise, efficient and less expensive when compared to manual labour. On the other hands, these advanced robots will reduce replace the human aspect of construction operations. Although in the beginning this change may be a bit problematic because craftsmanship is highly valuable for construction projects. Collaborative robots, also known as cobots, may serve as a solution to this problem. Cobots are basically designed to work together with human workers instead of replacing them completely. These advanced robots tend to boost and improve productivity by performing tasks that would otherwise consume extra time of the employees. They also considerably lower the operating costs by reducing the amount of labour required for a project.
                                                    It is also worth noting that cobots will have a major effect on collaborative work and work-related related relationships. It is obvious that they will alter the way we interact with each other and the world. This could lead to a dynamic shift within the development and construction teams where workers not only change roles but also adapt to less interactive tasks. If someone has to work with a robot all day instead of another person, it is possible that his feelings about work will change, in a good or a bad way. However, we still have to see how this will affect worker’s performance.
                                                      2. Increased Productivity on Repeatable Tasks
                                                        Human workers have to deals with several personal as well as environmental elements that robot do not experience. For example, humans get burned out, tired, or sometimes even bored with work. Their personal or family problems may also affect their performance. Robots, on the other hand, have none of these problems. They can continue to work indefinitely at the same quality and rate. Due to these reasons, robots offer a considerably higher level of efficiency as compared to human workers. Their work, however, can be hindered due to lack of maintenance or some other type of failure. This possibility can be eliminated by preventive maintenance, keeping the robots running for a longer period of time.
                                                          3. Better Operation Management and Handling of Logistics
                                                            Artificial intelligence can be used to handle logistics and other work operations in a more efficient way. Workers can be equipped with mobile devices through which they can communicate with their team members and other officials and update them regarding the work progress, forward requests and information, and alert them in case of any problem.  This setup can lead to improved productivity, improved safety, and better planning of collaborative tasks. It can completely transform the way construction teams work.
                                                            THE BOOM OF PRE-FABRICATION IN CONSTRUCTION INDUSTRY
                                                            THE BOOM OF PRE-FABRICATION IN CONSTRUCTION INDUSTRY
                                                            The future of construction industry is prefab construction, and it’s becoming more prevalent with every passing day. Contractors have realized the importance and advantages of modular construction and therefore have incorporated it into their construction processes. Prefabrication basically involves three major types of construction:
                                                              • Simple Elements: These include columns, beams and other parts of a structure that are manufactured off-site and then transported to the construction site to be bolted into place.
                                                              • Panelised Systems: These include insulation, waterproofing, utilities, and internal and external cladding. They are basically used for walls and are designed in a way that allows for flat pack transportation and quick assembly on the site.
                                                              • Volumetric Systems: These are 3D modular objects that comprise the wall, floor, and ceiling components for a room.
                                                                Modular components were initially made using the same materials as used in traditional construction, mainly steel and concrete, but the modules formed using these materials were very heavy and therefore difficult to assemble and transport. The new generation of modular buildings have offered a solution to these problems. These prefabricated modules are much lighter in weight and stronger in structure.
                                                                  Prefabrication has also allowed the homeowners to have high performing acoustic and thermal walls, ceilings, and floors by combining sustainable and durable materials into systems like sandwich panels etc.
                                                                    However, the modular construction types are primarily classified as follows:
                                                                    • Concrete Modular Buildings The buildings that are made using concrete modules which are assembled on the site afterwards are called concrete modular buildings. The primary feature of these buildings is that they are highly resistant to the course of time. Moreover, they’re very solid and don’t require any thorough maintenance. Also, we cannot skip the good acoustics of these modules. When it’s about construction of a house, concrete modules are a very affordable and durable choice. These modules are suitable for the construction of a single bedroom house to family residences with many bathrooms, terraces, suites, etc.
                                                                      • Wood Modular Buildings When we use wood in construction, there’s one thing we’re sure about, i.e. we’re opting for a more ecological and cheaper material. In case of prefab constructions, wood modules usually outstand for their simplicity, due to which they’re one of the most suitable options for natural areas like mountainous areas etc. On the other hand, as wood modules don’t stand the course of time well, they need more thorough maintenance and care. That’s why these wood modules are usually treated with an additional layer of varnish coatings to improve their resistance against weather conditions etc.
                                                                        • Steel Modular Buildings Steel constructions are considered as the most modern buildings today. The futuristic aspect that this material offers never goes unnoticed. Their design is eye-catching and at the same time suitable for thermal isolating covers which provides protection to the interior both in the summer and winter.
                                                                          • BENEFITS OF PREFABRICATION

                                                                            • Eco-friendliness Prefab construction is mostly commended for its sustainability and energy efficiency. Traditional construction methods involve extra materials that lead to more waste. However, as prefabricated modules are constructed in the factory, the leftover materials can be recycled there. Moreover, the controlled environment in a factory leads to more accurate construction, better air filtration, and tighter joints. All this together leads to better wall insulation and improves energy efficiency.
                                                                              • Financial Saving One of the major advantages of prefab construction is financial savings. People may think that custom-made pieces are more expensive, but with prefab construction this is not true. Modular construction takes into account price points and budget, and creates affordable options. Also, as prefab manufacturers get bulk discounts from the suppliers, it somewhat gets tricked down to the cost of the construction project.
                                                                                • Flexibility Prefab construction allows for design flexibility which leads to countless opportunities. Also, prefabricated modules can be easily dissembled and transported to a different site. This considerably reduces the need for raw materials, decreases overall construction time, and minimizes the expended energy.
                                                                                • BENEFITS OF IMPLEMENTING MOBILE TECHNOLOGY IN CONSTRUCTION
                                                                                  BENEFITS OF IMPLEMENTING MOBILE TECHNOLOGY IN CONSTRUCTION
                                                                                  The world is becoming increasingly mobilized and it has become necessary that construction companies recognize the need of implementing mobile technologies in their business. The construction industry continues to grow every year and therefore latest technology has become a need of the companies to survive in this constantly evolving industry. Mobile technology offers an integrated solution to construction companies to improve their business and ensure that they’re keeping pace with their competitors in the industry.
                                                                                    There are numerous benefits of implementing mobile technology in construction business. Among these benefits, the major ones are:

                                                                                    • Reduction of Costly Errors
                                                                                    • Using manual processes and paper forms have high risk of errors that can be extremely costly for the company owners. Moreover, physical paperwork is a slow and time-consuming task and can be difficult to read. It can also be lost easily in the shuffle of daily work. This can result in payroll mistakes, project delays, miscommunication, and many other issues. The use of mobile technology can minimize these costly errors by rearranging all the data into one place. Workers can enter their working hours directly from the worksite, which helps avoid payroll mistakes. All the team members can directly communicate with each other, which helps them finish their tasks efficiently.

                                                                                      • Reduction in Liability Issues and Other Legal Troubles
                                                                                      • Mobile technology collects data more accurately within the field as compared to manual data collection methods. This means that there is a lower chance of incurring any legal issue. For example, it is extremely important to carry out regular safety inspections on the construction sites, but paper forms fail to verify that safety inspections have been carried out at a specific place and time. This can put a company at risk for litigations and several other liability issues. By implementing mobile technology, companies can solve such issues and provide validated date and time stamps as a proof that they have performed safety inspections accurately and efficiently. In case of any disputes, this documentation can help the company settle any issues or legal action.

                                                                                        • Improved Software Safety and Security
                                                                                        • By using cloud-based technology, companies can give their data and important information the best possible protection. Many construction companies use their own servers and don’t realize that their systems can collapse anytime and as a result all their data is at a risk of being lost. Also, the servers are always at a risk of being compromised, which leaves all the important information and data of the company vulnerable to malevolent people. Mobile software ensures that the company’s data is always safe and secure and free from all such risks.

                                                                                          • Keeps Everyone in the Company Updated
                                                                                          • Mobile technology uses cloud networks which basically means that company will always stay updated about what’s happening in the office, on the construction site, warehouse etc. regular updates are provided to the company by the project teams that makes their work as seamless and efficient as possible.

                                                                                            • Customized Documentation
                                                                                            • Unlike manual paper forms documentation, mobile technology has enabled the companies to customize documentation according to their requirements. Workers can modify work order forms to include things like prices for particular parts and specific customer requirements or requests. It is difficult to modify paper forms to add additional information, which increases the risk of errors and miscalculations. Adopting mobile technology guarantees that all the documentation is accurate and complete, with the flexibility for the employees to add additional information.

                                                                                                IMPORTANCE OF DRONES IN CONSTRUCTION INDUSTRY
                                                                                                Drones have led to significant changes in the construction industry. They have changed the way construction processes take place. They have not only made construction operations easier but also improved their productivity.
                                                                                                  Here are some of the major contributions of drones in the industry and their impact on the construction processes:

                                                                                                    Land Survey

                                                                                                      Drones are rapidly replacing the traditional methods of land surveillance. They have become so popular and are being adopted so rapidly that some people have even replaced the classic expression “bird’s eye view” with “drone’s eye view”. Drones have greatly reduced the time and labour involved in land surveying. They have also eliminated much of the human error in the process with their ability to capture necessary date accurately.

                                                                                                        Improved Infrastructure

                                                                                                          Drones have provided superior intelligence and endurance on worksites. With their ability to collect and report real-time data, drones have enabled the project teams to complete their work faster. They have removed the need for manual labour to perform this task. In future, drones will take over even more complex tasks involved large projects. They have the potential to cut the time and cost it takes to build skyscrapers by a huge margin. Contractors who use drones in their work will be able to make much more profits and deliver projects on time.

                                                                                                            Improved Communication and Management

                                                                                                              Drone technology has made instant communication and connectivity possible on work sites. They are being used to maintain constant contact at construction sites. Drones with mounted cameras can also provide with video footages to facilitate surveillance and communication. They have allowed companies to keep a watchful eye on the workers to ensure they’re working properly and safely. Due to all these benefits, drones have become an invaluable tool or investors and project managers.
                                                                                                                Moreover, communication and management have seen significant improvement in efficiency to the ability of drones to collect real-time data. The time involved in gathering data has been considerably reduced due to the use of drones which has made worksite management easier and more efficient.

                                                                                                                  Improved Workers’ Safety

                                                                                                                    The use of drones in construction industry has led to a significant improvement in workers’ safety. Drones are being employed to constantly supervise the workers on site to ensure they’re working safely. In case of any risks, safety supervisors are able to take action on time before any mishap takes place. Drones have not only improved worker’s safety but also all over worksite security. The supervisors constantly monitor the construction sites to protect them from vandalism or theft. They also have the ability to survey dangerous locations safely and thus reduce worksite accidents. Manual surveys of these locations do not have to be conducted so worker’s safety is not at risk.

                                                                                                                      More Accurate Surveillance

                                                                                                                        Drones have the ability to capture everything at the same time. they not only reduce vandalism and theft and keep workers’ safe, but they also create a 24-hour real-time monitoring system. This monitoring system has been adopted by many construction companies and more and more companies are employing it with time. They elevate onsite safety and efficiency by a great margin. Drones have the ability to survey dangerous locations safely and thus reduce worksite accidents. Onsite inspection through drones drastically increases worksite safety and eliminates many safety hazards and dangers.

                                                                                                                                            What is BIM?

                                                                                                                                              Building Information Modelling (BIM) is basically information management using digital modelling, starting from initial building design all the way through its construction process, maintenance, and finally decommissioning. BIM is all about coordination and collaboration between contractors, stake holders, architects, and engineers in a 3D virtual construction environment, and it shares all the related information across these teams.
                                                                                                                                                BIM allows design and construction teams to coordinate and communicate information about the design and construction at every level of the building process. The shared information remains with the project, right from the beginning of construction till its entire lifetime.

                                                                                                                                                  Key Benefits of using Building Information Modelling

                                                                                                                                                    Applying Building Information Modelling in construction process and holding BIM certification can lead to following key benefits:

                                                                                                                                                      1. It allows visual data collection

                                                                                                                                                        BIM has provided the designers and builders with access to information about project sites that wasn’t accessible before. With better images of the Earth and improved mapping tools, today projects are analysed using aerial imagery, laser scans of infrastructure, and digital elevation. All these together help the builders and designers capture reality more accurately and streamline project preparations. BIM has allowed the designers to benefit from all the compiled input shared in a model and work in a more efficient way.

                                                                                                                                                          2. Reduced Onsite Waste

                                                                                                                                                            BIM provides a shared model to all the teams working on the project, so there’s less need to duplicate or redraft the drawings for different requirements of project teams. The model not only contains a drawing set but all the information related to the project, allowing each team to annotate and link their intellect to the project. The drawing tools of BIM are faster and more efficient than 2D drawing tools and each of the object is linked to a database. The database helps in calculations such as size and number of windows for quantity take-offs that update automatically with the advancement of the project. This quick and accurate computerized counting of project components saves significant material and labour costs.

                                                                                                                                                              3. Controlled Project Data and Reduced Uncertainty

                                                                                                                                                                BIM involves aids such as of auto-saving and project history backup so that the users can be sure that all the work they’ve done so far on the model has been captured and can be accessed any time. The access to version history of the model helps avoid disastrous losses like corruption of files that can interrupt productivity. Using BIM allows the project teams to detect, diagnose, and fix any problem with constructability timely before the construction begins. This can save significant amounts of time and money by preventing the need for any replacement materials.

                                                                                                                                                                  4. Improved Communication and Collaboration Between Teams

                                                                                                                                                                    Communicating and collaborating with models is much easier and more efficient than with drawing sets. It’s because there are various functions that are only possible through digital-model-based workflows. Much of the project management is now being carried out with the help of cloud. Here, there are multiple tools of the project teams to share their complex models and coordinate with their peers to keep them updated. Review and mark-up steps ensure that all the teams have given their input in the evolution of the project and they’re all ready to execute the finalized concept.

                                                                                                                                                                      5. Increased Speed and Efficiency of Processes by Better Sequencing of Steps

                                                                                                                                                                        A model with a well-constructed set of sub-models for each construction phase allows the teams to coordinate the sequencing of steps, crews, and materials for a more efficient and quick construction process. By merging project schedule with BIM model, project managers can watch a project being constructed virtually to ensure that the sequencing of steps within the schedule is accurate and delivering the expected outcome on time.

                                                                                                                                                                        Contractor vs. Subcontractor – What’s the difference?
                                                                                                                                                                        When people are planning to construct their own home, or a commercial building as a business start-up, they usually get confused whether to work with contractors or subcontractors. Well, basically, contractors deal directly with clients and oversee what the subcontractors are doing. They provide people with estimated costs and timeline for their building projects and keep them updated about the progress and occurring problems. One the other hand, several subcontractors are hired for a building project and each one of them is given a specific task like running the wiring across the building, installing pipes, and framing the walls, etc. The contractors are responsible for supervising the work of these subcontractors and ensuring that everything is on track.
                                                                                                                                                                          Moreover, contractors are usually self-employed and choose the projects they want to manage. They have mostly specialized in a certain skill and perform specific tasks of the project, while for the other tasks they hire subcontractors.
                                                                                                                                                                            Let’s have a look at the job responsibilities of both contractors and subcontractors and how they differ from one another:

                                                                                                                                                                              Job Responsibilities of Contractors

                                                                                                                                                                                As discussed above, contractors deal directly with the clients. They work with engineers and architects and draft the project plan. This planning includes the estimated cost and time of the project, project schedule, materials requires, and attributes that fulfil the client’s requirements. In addition, they have the responsibility to make adjustments in the plan in case there is an accident or any unforeseen complication.
                                                                                                                                                                                  The primary goal of contractors is to ensure that all the tasks are completed in a specific time frame and within a given budget in spite of accidents or unexpected problems.  Moreover, they participate in certain parts of the construction process, hire subcontractors and supervise their work, and organize the workforce. Contractors also deal with government and lawyers to ensure that all building requirements are fulfilled.

                                                                                                                                                                                    Job Responsibilities of Subcontractors

                                                                                                                                                                                      Subcontractors usually have a certain skill set and work on building projects under the guidelines of contractors. For every phase of a construction project, from land clearing to laying the foundation to final finishing, subcontractors are required. Also, each project phase needs a different subcontractor to complete the tasks. It is because all these tasks have their own tools set and require professionals who have specialized in their usage. These tools include trowels for pouring foundation, circuit breakers for working with the wiring, pipe cutters, and shovels etc. To use each of these tools, the subcontractor should have certain skills, and also the ability to work with the contractor and other subcontractors to ensure that part fits well with the others.
                                                                                                                                                                                        To help you understand better, we’ve listed down the pros and cons of hiring contractors and subcontractors.

                                                                                                                                                                                              Once you’ve decided to build your own home, or a commercial building for business purposes, the very next thing that comes you mind is execution of your idea. It is then that you begin to think of all the professional support that you may need to practically implement you plan. General contractors play a major role in construction projects and therefore their role cannot in any way be skipped.
                                                                                                                                                                                                When it comes to hiring workers, people often get confused whether to hire a general contractor or act as one. It is because hiring a general contractor will obviously cost you more and the budget of the overall project will increase. Some people are willing to bear these additional costs while some are not.
                                                                                                                                                                                                  So in case you are facing any such confusion, we have explained below how acting as a general contractor differs from hiring one.

                                                                                                                                                                                                    Acting as a General Contractor

                                                                                                                                                                                                      Being a property owner, you will be allowed by most of the jurisdictions to act as a general contractor for your own construction project.  Therefore, you can supervise all the activities taking place on the project site and ensure that everything is being completed by the given deadlines and within budget.  You can also hire and manage sub-contractors and assign tasks to workers.
                                                                                                                                                                                                        But why would you want to do all this?
                                                                                                                                                                                                          Here’s why:
                                                                                                                                                                                                          • The first reason is that you can save a lot of money that you would have to pay a hired general contractor.
                                                                                                                                                                                                          • Secondly, acting as your own general contractor will help you learn the whole process; you’ll have a better understanding of your business. Being a general contractor along with being an investor, you will have a better know-how of all the phases of construction process including HVAC systems, electrical work, and plumbing etc. You will get to know more about labour prices and material costs, and how much time it takes to install these materials.
                                                                                                                                                                                                          • The third benefit of doing so is getting more experience in this field. You will gain experience of being a real estate investor and along with that of being a general contractor. The experience you gain as a general contractor will be invaluable for your career as real estate investor.
                                                                                                                                                                                                          • Finally, you get the chance to deal with your subcontractors directly and monitor their work more closely. Whereas, if you hire a general contractor, you have contact the subcontractors through him or her.

                                                                                                                                                                                                          Hiring a General Contractor

                                                                                                                                                                                                          You’d know by now that a general contractor plays a central role in any construction project. Here’s why hiring one may be a good idea:
                                                                                                                                                                                                          • As they’re experienced professionals, they have a better understanding of the whole process. They know what permits are needed and how to get the project approved. They have dealt with inspectors and building codes before, so they make this process much easier.
                                                                                                                                                                                                          • Secondly, they know how to maximize efficiency of any job. They get the work done in the most efficient way possible. They schedule the subcontractors and workers and set deadlines to ensure everything goes smoothly.
                                                                                                                                                                                                          • Another major benefit of hiring a general contractor is that they can get labour and material at better prices due to their links in the industry. These better prices may help you reduce the overall budget of your project.
                                                                                                                                                                                                          • One of the greatest benefits of hiring general contractors is that they take warranty of the work they do. They will ensure that everything is going right and there are no delays. Even if there are any unforeseen complications in the project, they will come out and solve them as soon as possible. It’s because they want to work in long-term with their clients and keep them happy.
