Nothing is more problematic for contractors than projects that take longer than expected or are over budget. Through the integration of construction site knowledge into the design process, constructability review aids contractors in avoiding this. By removing work delays, rework during construction, and construction waste, constructability evaluation aids in minimizing project risk and overall project cost.
What is Constructability Building Review?
One essential component of a construction project is the constructability review. Reviewing all construction processes from beginning to end during the pre-construction or early design phase is the primary goal of the constructability evaluation. Before the start of the actual building, this constructability assessment assists in identifying and resolving various types of issues while minimizing mistakes, delays, and costs.
Constructability studies aim to save the owner time and money by identifying issues that may arise during building, such as mistakes, omissions, ambiguities, and conflicts. A CR will be advantageous for every construction project (and any suggested contract amendment).
Guidelines For A Constructability Review
There are a few things that a constructability reviewer needs to remember-
Focus on execution
Create the project, don't just concentrate on the issues. Only by spending the time to go through the laborious steps of construction will the issues be found. You shouldn't approach a constructability review as a task of reading through the construction documentation in search of issues, because those issues won't jump out at you.
Examine the interfaces of different systems
Problems are not found in the body of a system nearly as frequently as they are in the perimeter of a system where it interfaces with the many nearby systems and trades, regardless of whether they are interior, exterior, structural, or MEP.
Constructive Review
Be constructive when reviewing the preliminary documents. Be aware that the design papers are incomplete when conducting a constructability review on 50%, 75%, or even 90% of the documents. Additionally, you should avoid providing the design team with an extensive list of everything that has to be done. Initial assessments should concentrate on broad design strategies, fixing already-completed tasks, and locating the minute, easily overlooked details.
Focus on what's important
Think about these two things before you speak to the design team. First, "Will this affect the project's cost, timeline, or quality?" Furthermore, "Will the contractor, or subcontractors, require an answer to this issue to do their work?" Pose the remark if either of these questions has a yes response. Otherwise, commenting will take up time that the design team may be using to address other problems.
Conduct a thorough review
Even though a complete constructability study can take weeks or even months, the amount of time that can be saved by preparing a project in advance is exponential. Even while thorough assessments aren't always finished and integrated into design papers in time for bids, it's still crucial to deal with issues as soon as they arise in a project.
Benefits of Constructability Building Review
- Re-work-related change order difficulties will be less frequent since the errors will be found and fixed before the incorrect work is done.
- The luxury of time to analyze and haggle the general contractor's and subcontractors' change order pricing. Time restraints frequently drive you to quickly approve change order requests when issues are found while working.
- Preventing delays brought on by issues uncovered during building. Progress is often slowed, if not stopped, by the time it takes to analyze a problem and come up with a solution.
Summary
It's important to realize that constructability assessments are advantageous to a project in numerous ways. For instance, a constructability review is a great opportunity for the reviewer to understand and become familiar with all of the complex details of a project.
