The Ideal Timing of a Constructability Review for Maximum Impact

Sun, 16 Nov 2025 21:27:31 GMT

Introduction

In construction, timing is everything. Even the most thorough constructability review loses effectiveness if performed too late in the design process — after key decisions are made or documents are nearly ready for bid.

The most effective reviews are those performed early enough to influence the design, but late enough to evaluate a fully developed set of documents. Finding this balance is the key to achieving maximum impact — reducing change orders, improving coordination, and protecting project budgets.

Why Timing Matters

A constructability review is about more than catching mistakes — it’s about preventing risk before it reaches the job site. The earlier potential design issues are identified, the easier, and less costly they are to resolve.

According to industry research:

Change orders typically add 4–5% to project cost on average, and can reach 10–15% on poorly coordinated projects.
Each RFI costs roughly $1,000 to process and averages 9–10 days to resolve.

A well-timed review directly reduces these impacts by resolving coordination gaps long before they trigger costly field changes.

The Three Key Phases for Constructability Reviews

Understanding when to perform a Constructability Review is an important decision when undertaking this process. There are a number of variables that can affect the ideal timing for reviews, such as the size and complexity of the project, the design schedule, when the project will go to bid, the budget for constructability review, etc. There is no "one-size fits all" answer, however, here are some basic guidelines on deciding when to review your project.

100% Design Development

Timing: When the design team completes the DD set (typically 60–70% overall design progress).

Purpose: Identify big-picture coordination and constructability issues before systems are locked in.

Key Focus Areas:

Structural and MEP system coordination (ducts, beams, risers, penetrations)
Floor-to-floor heights, clearances, and access requirements
Material selections and constructability of proposed systems
Early logistics, phasing, and construction sequencing

�� Impact: This review ensures disciplines are aligned and that drawings are coordinated before construction documents begin.

90-95% Construction Documents

Timing: Near completion of the CD phase, typically when a project is submitted to plan check.

Purpose: Conduct a detailed, multi-disciplinary review to ensure the drawings and specifications are complete, coordinated, and buildable. This is the most critical review milestone—the point where all systems converge and coordination gaps are most visible.

Key Focus Areas:

Cross-discipline coordination between Architectural, Structural, Mechanical, Electrical, Plumbing, and Civil documents
Consistency between drawings and specifications
Details of waterproofing, finishes, and critical assemblies
Clarity of scope and intent to minimize contractor interpretation
Confirm all prior comments have been addressed (a “back-check review”).
Review final details, schedules, and specifications for completeness.
Verify scope clarity between drawings and specs (to minimize scope gaps during bidding).

�� Impact: Ensures the bid set is technically complete, coordinated, and ready for accurate pricing, reducing RFIs and change orders once construction begins.

100% Construction Documents (Back Chec k)

Timing: After the design team incorporates all comments from the 90–95% CD review and finalizes the documents.

Purpose: Verify that prior comments have been fully addressed. This final quality-assurance review closes the loop on all prior findings, confirming that the set is truly bid-ready.

Key Focus Areas:

Confirm all previous review comments have been resolved
Validate that no scope or coordination items were lost during edits

�� Impact: Provides confidence that the drawings issued for bid (or permit) are fully coordinated, reducing project risk from day one.

Additional Considerations

Small (under $20 million) and/or simple projects can get away with a two-step review such as a 90-95% CD primary review and 100% CD Back Check.
Large (above $20 million) and/or complex projects should always follow the three-step review process (100% DD / 90-95% CD / 100% CD Back Check).
If budget is limited, perform a single review at the 90-95% CD phase.
We highly recommend not skipping the back check — this will leave uncertainty about whether comments were addressed.
Thorough reviews take time and should be incorporate into the project schedule. Assume 2-3 weeks for smaller projects, 3-4 weeks (or longer) for larger projects, and 1-2 weeks for back check.

Structured constructability reviews at the three defined milestones create predictable outcomes and minimize surprises during construction. Ultimately, the most successful projects build these review milestones into their design schedule from the outset—treating the constructability review not as a reactive check, but as a proactive risk management tool.

Conclusion

The most effective constructability review process isn’t just about what’s reviewed—it’s about when.

By establishing a structured schedule at 100% DD, 90–95% CD, and 100% CD (back-check), project teams can proactively address issues, improve coordination, and deliver truly bid-ready documents.

The result: fewer surprises, fewer change orders, and a more predictable construction phase.

What Is a Constructability Review and How It Improves Project Outcomes

Sat, 15 Nov 2025 22:50:45 GMT

Introduction

Even the most carefully designed projects can face challenges once construction begins — from coordination conflicts to incomplete details. These issues often lead to change orders, delays, and cost overruns.

A constructability review bridges the gap between design and construction. By evaluating the plans through a builder’s lens, potential issues can be identified early, saving time and money while improving project quality and stakeholder confidence.

What Is a Constructability Review?

A constructability review is a comprehensive, step-by-step evaluation of a project's plans and specifications that combines architectural, engineering, and construction expertise. The goal is to uncover coordination issues, missing details, or constructability challenges early in the design process—long before they lead to RFIs, change orders, or schedule delays in the field.

Typical areas of focus include:

Conflicts between Architectural, Structural, and MEP systems
Missing dimensions, notes, or details
Ambiguous or inconsistent specifications
Access, sequencing, and construction logistics

Pain Points of a Construction Project

Industry studies show that even well-run construction projects experience change-order cost increases of ~4-5% of contract value; yet in more complex or poorly coordinated projects these can rise to 10% or more. Additionaly, each RFI (a symptom of incomplete or unclear design/coordination) costs roughly $1,080 on average and takes nearly 10 days to resolve — before even accounting for schedule / trade stacking / productivity losses.

How a Constructability Review Improves Project Outcomes

A well-executed constructability review does more than catch drawing errors — it transforms how a project moves from design to construction. By proactively identifying coordination gaps, conflicting details, and unclear specifications, a constructability review helps ensure the design intent can be built efficiently and without costly surprises. When integrated into the design process early, these reviews strengthen collaboration between architects, engineers, and builders, resulting in fewer RFIs, fewer change orders, and a smoother construction phase. In short, a constructability review improves every stage of the project lifecycle — from pre-bid coordination to final closeout — by enhancing efficiency, accuracy, and confidence across the entire team.

Reduces RFIs and Change Orders

Identifying gaps and conflicts before bid time through a structured constructability review drastically cuts the number of RFIs and costly change orders during construction.

Improves Bidding Accuracy

Clear, coordinated documents verified through a constructability review allow subcontractors to bid with confidence — reducing contingency pricing and producing more competitive bids.

Enhances Design Coordination

Reviews bring architects, engineers, and builders into alignment, ensuring systems and materials integrate as intended.

Saves Time and Money

Proactive issue resolution shortens schedules, prevents delays, and reduces costly rework in the field.

Strengthens Quality and Client Satisfaction

Owners benefit from a smoother build process and a higher-quality end product — a win for every stakeholder.

Conclusion: A Smarter Way to Build

A constructability review isn’t just another step in the process — it’s an investment in efficiency, coordination, and quality. By addressing design issues early, project teams can deliver better outcomes, reduce risk, and protect the owner’s budget and schedule. At Constructability Review Group, every review is performed by a team of specialists who understand both design intent and field execution, ensuring your project transitions from concept to completion with confidence.
