Constructability is defined as the incorporation of construction skills into project planning and designs so that builders have the best chance of delivering a quality project on time and within budget without jeopardizing safety. The processes in developing a constructability review process targeted at enhancing contract document quality.

To be effective, the constructability process should begin at the earliest conceptual stage of the project. The importance of hiring a construction specialist is emphasized. Their responsibilities would include researching the project's scope, inspecting the proposed location, estimating the time required for design and construction, and reviewing preliminary drawings for potential advantages and disadvantages in design choices.

The introduction of constructability evaluations into the highway design process will have a significant positive impact on the development of transportation facilities in the transportation area.To avoid any delays or errors, it is critical to address the issue early in the project.  Let's go over the essential stages of the constructability review process in this post.

Stages in Constructability Review Process

1. Design Stage

• Determine whether the construction design is realistic (between contractor, client, consultants, and architects/designers); architects can sometimes get carried away, and contractors know what is feasible or not.

• Determine whether the design can be completed within the budget.

• Determine whether the design will take longer to implement than the period allotted to the project.

2. Planning Stage

• Determine which materials are required to finish the design and which are the most cost effective while still fulfilling the design objective.

• Determine which construction equipment is required and which can be done without; remove luxury but non-essential construction equipment.

• Conduct a cost/benefit analysis on equipment quantity demands (for example, will employing a single tractor for several jobs, which takes more time, save more project money than investing in multiple tractors to complete specific roles more quickly?)

• Examine the intended site soil composition and how it will affect the project. 

3. Building Stage

• Examine how quickly the contractor is completing the construction, whether it is on time or behind schedule;

• Examine whether design expectations are being met;

• Examine how construction waste is being managed; and

• Examine again if any extraneous, non-essential equipment is being used during site construction.

Benefits of Constructability Review Process

While hiring an independent construction specialist has an upfront expense, constructability assessments eventually attempt to save ownership time and money by discovering difficulties or potential errors, omissions, ambiguities, or conflicts that may be faced during bidding or building.

Prior to construction, following a constructability assessment procedure, there may be higher quality bids with fewer addenda, clarifications, and bid date delays. Constructability evaluations can assist avoids disagreements and ambiguities during project execution, which reduces problems on the job site and helps maintain projects on schedule and on budget.

While they have many elements and can be difficult, knowing what a constructability review is will help your team prepare for and excel at your next development project. The project team receives a reduction in construction cost, direct field labor hours, construction schedule, and design rework hours for using the constructability review process.

Conclusion

The constructability review process is not about adding more activities to an already overburdened project team; rather, it is a formalized procedure that sensitizes and enables the team to begin thinking about project building as early as the feasibility stage. Owner advantages include dependability, maintainability, and operability.

A constructability assessment should also strive to decrease redundancy in quality control evaluations. Improvements in lost time event rate ease of people and material accessibility during construction and maintenance, labor productivity, increased security, and improved teamwork all benefit the project team.
