Constructability review

Established

Also: Buildability review, Constructibility review

A structured review of design documents by people with construction experience to find problems with buildability, sequencing, access, cost or safety before the design is issued for construction.

Explanation

Constructability reviews are typically held at defined design milestones (for example 50% and 90% construction documents) and are a core service of construction managers and design-builders. Reviewers check tolerances, interfaces between systems, temporary works, crane reach and laydown, prefabrication opportunities, material availability and site logistics. On BIM projects the review often uses the federated model, 4D sequencing and Clash detection results; findings are tracked as issues (for example in BCF) with responses from the design team.

Practical example

At 90% design for a pump station, the construction manager notes that the specified precast wet-well panels exceed local road-transport limits and proposes a split panel; the change is made before tender, avoiding a costly field redesign.

Why it matters

Problems found in review cost a fraction of the same problems found in the field as RFIs, change orders or rework.
