It ran 312 comments across nine disciplines. Thorough work. Genuinely good findings, including three that would have cost real money in the field.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The log was dated two business days before the bid date.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nobody could act on it. The design team could not issue 312 clarifications in 48 hours. The estimators had already priced the work. So the log got filed, the project went to bid, and roughly forty of those comments came back as RFIs during construction at somewhere between four and twenty times the cost of fixing them on paper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reviewer did nothing wrong. The <strong>constructability review process<\/strong> did. A review that arrives after the decisions it should inform is documentation, not risk management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article covers the process itself. When reviews happen, who runs them, what each phase should produce, how comments get resolved, and how the whole cycle gets governed so that findings actually change the drawings. For the content of what reviewers look for, see the companion article on the constructability review checklist. For how findings get classified, see the article on types of constructability issues.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>KEY TAKEAWAY<\/strong><br>Timing beats thoroughness. A review at 60 percent design development with 40 findings changes more outcomes than a review at 95 percent construction documents with 300. The process question is not &#8220;did we review?&#8221; but &#8220;did we review while the design could still move?&#8221;<\/th><\/tr><\/thead><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Key Definitions: What a Constructability Review Is and Is Not<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The term gets used loosely enough that two people can agree to &#8220;do a constructability review&#8221; and mean completely different activities. Here is the vocabulary as it functions on a real project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Constructability review<\/strong> is a structured examination of design documents by people who will build the work, performed to identify conditions that will make construction difficult, expensive, slow, unsafe, or impossible, while the design can still be changed economically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two parts of that definition carry weight. &#8220;By people who will build the work&#8221; separates it from design QA. &#8220;While the design can still be changed economically&#8221; separates it from field problem-solving.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The governance process around<strong> the constructability review<\/strong> is the control process<strong> <\/strong>around the examinations. Constructability reviews are scheduled, reviewers are assigned, formats for comments are established, and the review process is completed and documented.<strong> <\/strong>The review is an activity. The process is what makes it repeatable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It helps to distinguish four related reviews that get confused constantly.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Review type<\/strong><\/strong><\/th><th><strong><strong>Question it answers<\/strong><\/strong><\/th><th><strong><strong>Who performs it<\/strong><\/strong><\/th><th><strong><strong>Typical timing<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Design QA \/ QC<\/strong><\/td><td>Is the design internally consistent and code-compliant?<\/td><td>Design team, internal<\/td><td>Before each issuance<\/td><\/tr><tr><td><strong>Constructability review<\/strong><\/td><td>Can this be built safely, affordably, and in sequence?<\/td><td>Contractor, CM, VDC<\/td><td>At each design milestone<\/td><\/tr><tr><td><strong>BIM coordination<\/strong><\/td><td>Do modeled systems physically conflict?<\/td><td>VDC \/ trade detailers<\/td><td>After CD, before fabrication<\/td><\/tr><tr><td><strong>Peer review<\/strong><\/td><td>Is the engineering approach sound?<\/td><td>Independent engineer<\/td><td>At owner request<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Constructability review overlaps with BIM coordination and gets substituted for it, which causes trouble in both directions. Coordination finds geometric conflicts between modeled elements. Constructability review finds conditions a model will never flag: a wall detail with no installation sequence, a mechanical room with a door too small for the equipment, a waterproofing transition drawn at two different elevations on two different sheets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Four attributes travel with constructability and each one generates different comments.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Lens<\/strong><\/strong><\/th><th><strong><strong>What the reviewer is asking<\/strong><\/strong><\/th><th><strong><strong>Example finding<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Constructability<\/strong><\/td><td>Can this be physically installed in the space and sequence shown?<\/td><td>Beam pocket leaves no room for the shoring the detail requires<\/td><\/tr><tr><td><strong>Biddability<\/strong><\/td><td>Can a trade price this without guessing?<\/td><td>Finish schedule references a room type that does not appear on plans<\/td><\/tr><tr><td><strong>Operability<\/strong><\/td><td>Can the owner run the building as designed?<\/td><td>Control valve located above a hard ceiling with no access panel<\/td><\/tr><tr><td><strong>Maintainability<\/strong><\/td><td>Can components be serviced and replaced over the life cycle?<\/td><td>Air handler shown with 18 inches of coil pull space against a 60 inch coil<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>FIELD REALITY<\/strong><br>Most teams review for constructability and biddability, then stop. Operability and maintainability comments come from the owner&#8217;s facilities group, who are usually not invited to the review. That absence is the easiest gap to close and it\u2019s totally free, just make the calendar invite.<\/th><\/tr><\/thead><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Objectives: What the Process Is Supposed to Deliver<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A review process without stated objectives becomes a comment-generating exercise measured by volume. Volume is a terrible metric. Three hundred low-value comments bury the twelve that mattered, and the design team learns to skim.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Move risk earlier.<\/strong> Shift issue discovery from construction into design, where a change costs a drawing revision rather than demolition.<\/li>\n\n\n\n<li><strong>Reduce RFI volume attributable to document gaps.<\/strong> Not all RFIs, just the ones caused by missing details, conflicts, or ambiguity that a reviewer could have caught.<\/li>\n\n\n\n<li><strong>Protect the bid.<\/strong> Give estimators documents complete enough to price without contingency padding or exclusion lists.<\/li>\n\n\n\n<li><strong>Establish sequence feasibility.<\/strong> Confirm the work can actually be built in the order the schedule assumes.<\/li>\n\n\n\n<li><strong>Create a defensible record.<\/strong> Document what was flagged, when, and how it was resolved, which matters enormously if the project ends up in dispute.<\/li>\n\n\n\n<li><strong>Build institutional knowledge.<\/strong> Feed field lessons back into the checklists so the same issue is caught earlier next time.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Objective<\/strong><\/strong><\/th><th><strong><strong>Indicator<\/strong><\/strong><\/th><th><strong><strong>Typical baseline<\/strong><\/strong><\/th><th><strong><strong>Achievable target<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Earlier risk discovery<\/strong><\/td><td>Share of findings raised at or before DD<\/td><td>20 to 35 percent<\/td><td>60 percent or better<\/td><\/tr><tr><td><strong>Lower document-driven RFIs<\/strong><\/td><td>RFIs traceable to a missed reviewable condition<\/td><td>35 to 50 percent of all RFIs<\/td><td>Under 20 percent<\/td><\/tr><tr><td><strong>Bid protection<\/strong><\/td><td>Trade exclusions and clarifications per bid package<\/td><td>8 to 20<\/td><td>Under 5<\/td><\/tr><tr><td><strong>Comment quality<\/strong><\/td><td>Share of comments accepted and incorporated<\/td><td>40 to 60 percent<\/td><td>80 percent or better<\/td><\/tr><tr><td><strong>Resolution discipline<\/strong><\/td><td>Comments closed before the next issuance<\/td><td>Often under half<\/td><td>95 percent<\/td><\/tr><tr><td><strong>Knowledge capture<\/strong><\/td><td>New checklist items added per project<\/td><td>Zero<\/td><td>10 to 25<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Notice what is not on that list. Total comment count. Reviewer hours. Number of disciplines covered. Those are activity measures, and a process optimized for activity measures produces exactly the log that GC handed me.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Why the Process Matters More Than the Reviewer<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the uncomfortable part. Most firms treat constructability review as a talent problem. Assign a good superintendent, get good findings. There is truth in that, and it is also why so many programs never improve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A talented reviewer with no process produces findings that depend on which sheets caught their eye and how much time they had that week. The same person reviewing the same set twice will produce different comments. That is not a criticism of the reviewer. It is a property of unstructured expert judgment applied to 900 sheets under deadline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Process converts individual skill into organizational capability. It decides the review phase, order of disciplines, prompts provided to the reviewer, in what order comments appear on the design team\u2019s electronic tablets, whether anyone confirms the fix, etc.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cost curve is the whole argument. A condition caught during design development costs a drawing revision. The same condition caught during construction documents costs a revision plus a re-price. Caught after buyout, it becomes a change order. Caught in the field, it becomes demolition, rework, delay, and sometimes a claim.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Discovered at<\/strong><\/strong><\/th><th><strong><strong>What it takes to fix<\/strong><\/strong><\/th><th><strong><strong>Relative cost<\/strong><\/strong><\/th><th><strong><strong>Schedule exposure<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Schematic design<\/strong><\/td><td>Design decision, no rework<\/td><td>1x<\/td><td>None<\/td><\/tr><tr><td><strong>Design development<\/strong><\/td><td>Drawing revision<\/td><td>2x to 4x<\/td><td>None<\/td><\/tr><tr><td><strong>Construction documents<\/strong><\/td><td>Revision plus re-coordination<\/td><td>5x to 10x<\/td><td>Minimal<\/td><\/tr><tr><td><strong>Bid \/ buyout<\/strong><\/td><td>Addendum, re-pricing, scope renegotiation<\/td><td>10x to 20x<\/td><td>Days<\/td><\/tr><tr><td><strong>Shop drawings<\/strong><\/td><td>Redesign plus fabrication delay<\/td><td>20x to 40x<\/td><td>Weeks<\/td><\/tr><tr><td><strong>Field installation<\/strong><\/td><td>Demolition, rework, change order, possible claim<\/td><td>40x or more<\/td><td>Weeks to months<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Those multipliers are directional rather than precise, and they vary by trade. The shape of the curve is the point. It is not linear. It steepens hard after documents are issued for bid, which is exactly why a review scheduled late has so little leverage no matter how good the findings are.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>INDUSTRY INSIGHT<\/strong><br>The most valuable constructability comment is rarely the most technically impressive one. It is the boring observation made early enough that fixing it required nothing but a phone call.

Nobody owns comment resolution, and the design team receives comments in a format that feels like criticism rather than collaboration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both are governance problems, and both are fixable with an explicit assignment of roles.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Stakeholder<\/strong><\/strong><\/th><th><strong><strong>Contribution to the review<\/strong><\/strong><\/th><th><strong><strong>What they need from the process<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Owner \/ Developer<\/strong><\/td><td>Sets expectations, funds the review, arbitrates cost impacts<\/td><td>Evidence that findings reduced risk, not just paperwork<\/td><\/tr><tr><td><strong>Preconstruction Manager<\/strong><\/td><td>Owns the schedule, assembles the team, issues the log<\/td><td>Clear phase gates and reviewer availability<\/td><\/tr><tr><td><strong>Superintendent<\/strong><\/td><td>Sequence feasibility, access, site logistics, means and methods<\/td><td>Enough time and a checklist that prompts field thinking<\/td><\/tr><tr><td><strong>Project Manager<\/strong><\/td><td>Comment resolution tracking and design team liaison<\/td><td>A single log, not comments scattered in email<\/td><\/tr><tr><td><strong>Estimator<\/strong><\/td><td>Biddability, quantity clarity, scope gaps affecting price<\/td><td>Findings early enough to price rather than caveat<\/td><\/tr><tr><td><strong>BIM \/ VDC Manager<\/strong><\/td><td>Model-based spatial checks, congestion analysis<\/td><td>Model availability at the right level of development<\/td><\/tr><tr><td><strong>Trade partners (if engaged)<\/strong><\/td><td>Installation reality, tolerances, prefabrication feasibility<\/td><td>Early engagement and a reason to invest the hours<\/td><\/tr><tr><td><strong>Design team<\/strong><\/td><td>Disposition of every comment, revision issuance<\/td><td>Comments that are specific, located, and non-accusatory<\/td><\/tr><tr><td><strong>Owner facilities group<\/strong><\/td><td>Operability and maintainability findings<\/td><td>An invitation, which they frequently do not get<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The RACI below reflects a common delivery structure where the contractor leads the review and the design team disposes of comments.

Reviewing for detail at 30 percent wastes everyone&#8217;s time because the detail does not exist yet. Reviewing for concept at 90 percent is too late to matter. Each phase has questions it is uniquely positioned to answer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Schematic Design (roughly 30 percent)<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Documents are conceptual. Systems are located but not detailed. This is the only phase where big moves are still cheap, so the review should be about feasibility and logistics rather than dimensions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Useful questions here: Can the site accept the crane and laydown this footprint implies? Does the structural system suit the local labor market and the schedule? Is the floor-to-floor dimension realistic for the systems the program requires? Where is the phasing line, and does it work with existing operations?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A single finding at this stage can be worth the entire review budget. On one hospital addition, a reviewer noted that the proposed structural bay conflicted with the imaging equipment layout the owner had already procured. That comment cost fifteen minutes. Found six months later, it would have cost a redesign of an entire wing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Design Development (roughly 60 percent)<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the highest-leverage review phase, and the one most often skipped because the schedule is tight and everyone assumes the CD review will catch things.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Systems are located, major details are emerging, and changes are still absorbable. The review should focus on spatial adequacy, coordination between disciplines, access and clearance, and whether the sequence the schedule assumes is physically possible. Ceiling space is the classic DD finding: once ductwork, cable tray, sprinkler main, and structure are all located, the reviewer can check whether the plenum actually accommodates them before anyone details the transitions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Construction Documents (roughly 90 percent)<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now the review shifts to completeness and consistency. Are details drawn where they are referenced? Do the drawings and specifications agree? Are dimensions closed? Are transitions and terminations shown, or do they trail off at a match line?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is also the biddability review. An estimator reading the set should be able to price every scope item without inference. Where they cannot, that is a comment, and it is worth more than most technical findings because it prevents a priced assumption from becoming a contract dispute.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Pre-Bid and Issued for Construction<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A final pass focused narrowly on the items that generate the most RFIs: interface conditions between trades, penetration and sleeving details, embeds and blockouts, and anything the previous review flagged that came back unresolved.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keep this pass short and targeted. A broad review here produces the 312-comment log that nobody can use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>During Construction<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Constructability review does not stop at award. Shop drawings and deferred design packages arrive throughout the job, and each one deserves the same lens. A curtain wall shop drawing, a stair fabrication package, a headwall assembly: all of these introduce constructability questions that the contract documents could not have answered.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Phase<\/strong><\/strong><\/th><th><strong><strong>Review focus<\/strong><\/strong><\/th><th><strong><strong>Typical duration<\/strong><\/strong><\/th><th><strong><strong>Primary deliverable<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Schematic design<\/strong><\/td><td>Site logistics, system selection, phasing feasibility, floor-to-floor adequacy<\/td><td>1 to 2 weeks<\/td><td>Feasibility memo, 15 to 40 findings<\/td><\/tr><tr><td><strong>Design development<\/strong><\/td><td>Spatial coordination, clearances, access, sequence feasibility<\/td><td>2 to 3 weeks<\/td><td>Comment log, 60 to 150 findings<\/td><\/tr><tr><td><strong>Construction documents<\/strong><\/td><td>Completeness, consistency, biddability, detail adequacy<\/td><td>2 to 4 weeks<\/td><td>Comment log plus bid clarification list<\/td><\/tr><tr><td><strong>Pre-bid \/ IFC<\/strong><\/td><td>Interfaces, penetrations, unresolved prior comments<\/td><td>3 to 5 days<\/td><td>Targeted punch list of open items<\/td><\/tr><tr><td><strong>Shop drawings<\/strong><\/td><td>Fabrication feasibility, field fit, installation sequence<\/td><td>Rolling<\/td><td>Review comments per package<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Between phases sits the part of the process that gets neglected: the resolution cycle.

Sheet number, grid, level, detail callout. A finding without a location is an opinion, and design teams reject opinions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>AI-Assisted Opportunities in the Review Process<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Constructability review has a structural weakness that AI addresses well. The work is exhaustive reading against a known set of criteria, performed under time pressure by people whose attention degrades across hundreds of sheets. Coverage, not intelligence, is the binding constraint.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A checklist-driven AI review inverts the economics. Instead of a reviewer choosing which sheets to examine closely, the system applies trade-specific checklists across the entire set and returns findings with drawing locations, a description of the condition, and its likely execution impact. The reviewer&#8217;s time moves from searching to judging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That distinction matters for how the output should be treated. The system flags conditions. It does not decide whether a condition is acceptable. A 6 inch plenum clearance might be fine or might be fatal depending on what has to run through it, and that call belongs to someone who has installed ductwork.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Process step<\/strong><\/strong><\/th><th><strong><strong>AI contribution<\/strong><\/strong><\/th><th><strong><strong>Human decision retained<\/strong><\/strong><\/th><th><strong><strong>Output<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Checklist application<\/strong><\/td><td>Runs discipline checklists across every sheet at equal depth<\/td><td>Which checklists apply to this project type<\/td><td>Findings list with sheet and grid references<\/td><\/tr><tr><td><strong>Note and detail extraction<\/strong><\/td><td>Pulls notes, dimensions, and detail callouts into structured data<\/td><td>Interpreting ambiguous or unusual annotations<\/td><td>Queryable drawing content index<\/td><\/tr><tr><td><strong>Reference integrity check<\/strong><\/td><td>Finds details referenced but not drawn, and orphan callouts<\/td><td>Deciding which gaps are material<\/td><td>Missing-detail report<\/td><\/tr><tr><td><strong>Drawing-to-spec conflict<\/strong><\/td><td>Compares drawing content against specification requirements<\/td><td>Judging which document governs<\/td><td>Conflict list by spec section<\/td><\/tr><tr><td><strong>Clearance screening<\/strong><\/td><td>Flags dimensions below stated minimums<\/td><td>Whether the clearance is actually adequate<\/td><td>Clearance exception list<\/td><\/tr><tr><td><strong>Severity triage<\/strong><\/td><td>Proposes a severity ranking from condition patterns<\/td><td>Final severity, which drives design team attention<\/td><td>Ranked comment log<\/td><\/tr><tr><td><strong>Prior-comment carryover<\/strong><\/td><td>Checks whether last cycle&#8217;s findings appear resolved<\/td><td>Confirming true incorporation<\/td><td>Open-item verification list<\/td><\/tr><tr><td><strong>Discipline report generation<\/strong><\/td><td>Assembles findings into a trade-specific report<\/td><td>Editing, adding field judgment, issuing<\/td><td>Draft constructability report<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The prompt pattern that works in practice is narrow and trade-scoped. &#8220;Generate a mechanical constructability report for levels 2 through 4.&#8221; &#8220;Review ceiling coordination in the east wing.&#8221; &#8220;Check plumbing rough-in against the structural set.&#8221; Broad requests produce broad output, so the log is the broad output of the 312-comment request, again.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>BEST PRACTICE<\/strong><br>A one-click traceability mechanism must be implemented to each AI-generated location to the highlighted location in the diagram.

What changes is which phase carries the most risk and which disciplines deserve the deepest review.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong><strong>Project type<\/strong><\/strong><\/th><th><strong><strong>Highest-risk phase<\/strong><\/strong><\/th><th><strong><strong>Review emphasis<\/strong><\/strong><\/th><th><strong><strong>Characteristic finding<\/strong><\/strong><\/th><\/tr><\/thead><tbody><tr><td><strong>Commercial office<\/strong><\/td><td>DD<\/td><td>Core and shell to fit-out interface, ceiling zones<\/td><td>Plenum depth inadequate once tenant systems are added<\/td><\/tr><tr><td><strong>Data center<\/strong><\/td><td>SD and DD<\/td><td>MEP density, module repeatability, service access<\/td><td>Maintenance clearance lost in repeated equipment rows<\/td><\/tr><tr><td><strong>Healthcare<\/strong><\/td><td>DD<\/td><td>Above-ceiling coordination, medical gas, infection control phasing<\/td><td>Access panel omitted at an in-ceiling valve<\/td><\/tr><tr><td><strong>Industrial \/ process<\/strong><\/td><td>SD<\/td><td>Equipment access, structural interface, utility routing<\/td><td>No rigging path to set equipment after enclosure<\/td><\/tr><tr><td><strong>Manufacturing<\/strong><\/td><td>DD<\/td><td>Owner-furnished equipment interfaces, floor tolerance<\/td><td>Utility termination point undefined between GC and vendor<\/td><\/tr><tr><td><strong>Infrastructure<\/strong><\/td><td>SD and DD<\/td><td>Staging, phasing, traffic control, agency constraints<\/td><td>Sequence assumes closure the permit does not allow<\/td><\/tr><tr><td><strong>Multifamily residential<\/strong><\/td><td>DD<\/td><td>Repetitive unit details, shaft alignment, envelope transitions<\/td><td>Waterproofing transition drawn differently on two sheets<\/td><\/tr><tr><td><strong>Institutional \/ education<\/strong><\/td><td>CD<\/td><td>Biddability under public procurement, summer phasing<\/td><td>Finish schedule references undefined room types<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Multifamily: Repetition Amplifies Everything<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On a recent review of a multifamily project, the architectural and interiors sets produced fourteen findings across eight coordination categories. Modest count. What made them significant was repetition. A single unresolved detail at a unit-type balcony threshold repeats across every stack in the building.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process implication is specific: on repetitive work, review depth should be concentrated on unit types and typical details rather than distributed evenly across sheets. Reviewing one unit type exhaustively beats reviewing forty sheets superficially.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Healthcare: Above the Ceiling Is Where the Money Is<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hospital plenums carry ductwork, medical gas, sprinkler, cable tray, pneumatic tube, structural elements, and hangers, inside a floor-to-floor dimension that value engineering usually squeezed at SD. Every one of those systems has a maintenance access requirement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The review process needs a dedicated above-ceiling pass at DD with the mechanical contractor present if at all possible. Reviewing those systems separately by discipline, which is the default, guarantees that the interaction between them goes unexamined.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Infrastructure: The Sequence Is the Design<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On phased infrastructure work, constructability review is largely a review of the staging plan against the permit conditions and the traffic control requirements. A structurally sound design that requires a lane closure the agency will not approve is not constructible, and no amount of detail review will surface that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the clearest case for the SD review. Once the phasing is committed and the permits are in progress, sequence findings have almost no leverage left.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Frequently Asked Questions<\/strong><\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>What is the constructability review process?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Constructability review is the methodical process that a construction specialist uses to analyze design documents and impacts of design decisions at key points during the project. The findings of the constructability review are documented in a priority log, sent to the design team to be acted on, and ensured to be incorporated in the next version. This process is different from a single review process, as it has phase gates, assigned ownership, a severity scale, a resolution workflow, and a feedback loop back into the checklists.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>When should constructability reviews take place?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At a minimum, at design development and construction documents. A schematic design review is where the highest-value findings live because system selection, floor-to-floor dimensions, and site logistics are still changeable. A short pre-bid pass on interfaces and unresolved items is worth the few days it takes. Reviews should also continue during construction on shop drawings and deferred design packages. If you can only do one, do design development, not construction documents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Who should perform a constructability review?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">People who will build or price the work. A superintendent for sequence, access, and means and methods. An estimator for biddability and quantity clarity. A VDC manager for spatial coordination. A preconstruction manager to own the cycle. Trade partners where they are engaged early enough. The owner&#8217;s facilities group for operability and maintainability, which is the most commonly missing voice. A review performed only by design professionals is design QA under a different name.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>How long does a constructability review take?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For a mid-size commercial project, expect one to two weeks at schematic design, two to three at design development, and two to four at construction documents, plus a resolution cycle of one to two weeks after each. Those durations assume reviewers with allocated time rather than reviewers squeezing it between other duties. The most common cause of a shallow review is not lack of skill but a five-day window on a three-week job.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>What should a constructability review report contain?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Each finding needs a unique identifier, a document location (sheet, grid, level, detail reference), a factual description of the observed condition, the discipline or disciplines affected, an assessed severity, the likely execution impact, and a disposition field for the design team&#8217;s response. A narrative summary section helps owners understand themes. What it should not contain is instruction on how to redesign, which invites professional liability questions and antagonizes the design team.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>How is constructability review different from BIM clash detection?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Clash detection finds geometric interference between modeled elements. Constructability review examines whether the work can be built, priced, sequenced, operated, and maintained. Clash detection cannot find a missing detail, a drawing-to-specification conflict, an unbuildable sequence, an inadequate rigging path, or a valve with no access panel, because none of those are geometric collisions. Both are necessary. Neither substitutes for the other, and treating coordination as the review is a frequent and costly assumption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>How many comments should a review produce?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Fewer and better ranked beats more. The useful measure is acceptance rate and incorporation rate rather than volume.  A design development log of 80 findings with an 80 percent acceptance rate yields a healthier result than 250 findings with 45 percent acceptance, because the second log indicates to you that reviewers were padding and the design team was skimming. If the log exceeds roughly 150 items at any single gate, triage before issuing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>What severity scale should we use?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Three tiers is about enough and five is very likely too many. An appropriate scale: critical means construction cannot continue as documented and a cost or time impact is eminent; significant means a construction condition will yield a request for information (RFI) or field conflict if left unaddressed; and advisory means that the construction condition, while noteworthy, does not adversely affect the constructability of the work as documented.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Can AI perform a constructability review on its own?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No, and vendors claiming otherwise are overselling. AI is very good at checklists. It can examine a full set of drawings and a notational and dimension set, finding referenced but not shown elements and recording if conditions outside the stated minimums are reported. AI does not understand that a case of clearance is acceptable in one case and unacceptable in another case, and does not understand means and methods. The realistic model is AI for coverage and a human for judgment, with every finding traceable to a drawing location so the human can verify quickly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>How do we get the design team to engage constructively?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Three things change the dynamic. Write findings as observed conditions with locations rather than as instructions or criticisms. Rank them, so the design team can see you distinguished the critical from the trivial. And accept rejections gracefully when the reason is sound, then check whether the rejection reveals a flaw in your checklist. Design teams disengage from reviews that read like fault-finding exercises, and they are not wrong to.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>How do we measure whether the review process is working?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Track the share of findings raised at or before design development, the comment acceptance rate, the incorporation verification rate, and the proportion of RFIs during construction that trace back to a condition a reviewer could have caught. That last metric is the real one, and it takes two or three completed projects to trend. Also count new checklist items added per project, because a process with no feedback loop is not improving regardless of what the other numbers show.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong><strong>Does the review process change on design-build or IPD projects?<\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The mechanics stay similar but independence becomes the problem. When the same organization designs and builds, the reviewer and the designer report to the same leadership, and uncomfortable findings get resolved informally without ever entering a log. The fix is structural: assign review to staff outside the design reporting line, require a written log regardless, and have the owner or an independent party receive it. On integrated delivery the upside is that trade partners are already at the table, which makes early-phase reviews substantially stronger.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Expert Recommendations<\/strong><\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Put review windows in the design services agreement.<\/strong> Reviews that live only in a project schedule get compressed first when the schedule slips.<\/li>\n\n\n\n<li><strong>If you can only fund one review, fund design development.<\/strong> Construction documents feels safer because there is more to look at. Design development is where findings still change something.<\/li>\n\n\n\n<li><strong>Pull three closed projects and classify the RFIs.<\/strong> Count how many trace to a condition a reviewer could have caught. That number is your business case, and it is usually larger than leadership expects.<\/li>\n\n\n\n<li><strong>Assign verification to the person who wrote the comment.<\/strong> They are the only one who will notice a response that technically addresses the wording but misses the condition.<\/li>\n\n\n\n<li><strong>Invite the owner&#8217;s facilities manager to design development.<\/strong> One afternoon of their time reliably produces findings no contractor reviewer will generate.<\/li>\n\n\n\n<li><strong>Rank before you issue.<\/strong> An unranked log transfers the triage burden to the design team, who will do it based on what is easiest to answer.<\/li>\n\n\n\n<li><strong>Run AI-assisted review in parallel for one full cycle.<\/strong> Compare the two logs. The overlap calibrates trust and the divergence exposes checklist gaps.<\/li>\n\n\n\n<li><strong>Hold a one-hour lessons session before the team demobilizes.<\/strong> Field issues that trace back to a reviewable condition become next year&#8217;s checklist items. This is the cheapest improvement mechanism available and almost nobody does it.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong><strong>Conclusion<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">That 312-comment log was good work performed inside a broken process. The reviewer found real problems. The process delivered them at a moment when finding problems no longer helped anyone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Everything that separates an effective constructability review process from an expensive one comes down to a few structural decisions. Review at the phase where design can still move. Rank findings so attention lands where it should. Give every comment a location so it can be verified. Confirm that accepted comments actually reached the documents. Feed what the field learned back into the checklists.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">None of that requires new technology, and all of it gets substantially easier with it. AI-assisted review solves the coverage problem that has always limited manual review, applying checklists across a full set at consistent depth rather than at whatever depth the calendar allowed. What it does not solve is process design. A tool that generates findings faster inside a process that delivers them too late just produces a longer log two days before bid.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>KEY TAKEAWAY<\/strong><br>Review early, rank honestly, locate every finding, verify incorporation, and close the loop into your checklists.
