The constructability review guidelines are performed as projects are being developed to make sure they are affordable, buildable, and maintainable. Constructability evaluations entail making the best use possible of a project's planning and development process of construction knowledge and experience. Constructability evaluations aim to increase construction workers' involvement in project planning and development, which is one of their main objectives.

A project's clear and practical building methods are checked as part of a systematic procedure called a constructability review. Beginning at project inception and continuing throughout project development is the constructability review process. The planning and development of the project includes a number of constructability reviews. The Constructability Review guidelines are the culmination of the reviews.

Constructability Review Guidelines: Pre-Design Stage

Preliminary Concept Field Review

The Design Manual's instructions for the Preliminary Concept Field Review must be followed. The District's Design, Construction, Materials, and Maintenance professionals, as well as others as necessary for the particular project, must at the very least be present for the field review. The project will be evaluated for scope and constructability during the field review.

Concept Approval

As specified in the Design Manual, a Concept Report must be finished and authorized. The estimate is refined during project development, which also establishes design standards, alternative options, and expenses.

The District's Construction, Maintenance, and Materials divisions should receive copies of the Concept Report that has been approved.Throughout the project development phase, the Regional/Resident/Maintenance Engineers and personnel play a significant role in providing opinions on constructability issues.

Constructability Review Guidelines: Design Stage

Project Levels for Constructability Reviews

Constructability review guidelines must be a part of the current design review procedure described in the Design Manual. Projects are divided into level one, level two, and level three categories to determine the level of constructability study necessary. Level one projectincludes those that are State Simple and Federal Simple.

Projects classified as State Complex and Federal Complex are typically level two. Projects with unique, inventive, pricey, or difficult design characteristics may be categorized as level three for state complex and federal complex projects. The District will decide whether to assign the project a level three designation.

Project Constructability Review Team

For each project, a Constructability Review Team will be constituted. The team must be constituted for level one projects prior to the final design review, or sooner if the District deems it necessary. Prior to the Preliminary Design Review, the team must be formed for level two and level three projects.

Final Design Review

All members of the Constructability Review Team will receive copies of the Final Design papers for projects at levels one, two, and three. A minimum three-week evaluation period will be provided to the constructability review team. Depending on how complex the plans are, the approval period for level three projects may be prolonged.

The Constructability Review Guidelines Method

The CR strategy is another point of contention among constructability managers. One strategy is to break plans into CSI divisions or work disciplines, with each reviewer focusing on one or a few disciplines. For instance, a reviewer in charge of the paving section would look through the paving plans and the specifications that cover base course and striping, as well as flexible and rigid pavements.

Another strategy would involve different people reviewing the requirements, the drawings, and the special provisions.Another strategy is to assign each reviewer to thoroughly examine all plans and specifications. Depending on the amount of time available, the number of disciplines involved, the availability of reviewers, and the reviewers' level of knowledge, the best course of action may be chosen.

Conclusion

The constructability review guidelines are crucial to the design phase. Conflicts that may affect build time and expense will be revealed by reviews conducted properly. Reviews must be conducted independently of the designer and finished well in advance of the start of the bid cycle so that adjustments may be made in plenty of time.

The CR procedure can be taught, even though it is practically impossible to train someone to write pertinent review comments. The designs, specifications, bid form, and other special clauses must all be examined for constructability, even though not all documents need to be.
