Interior finishes change orders on multifamily projects follow predictable patterns. The same five or six sources generate the majority of finishes-related change orders across projects in every market. Most of them are not the result of design changes or unforeseen conditions. They are the result of coordination failures that could have been identified and resolved at pre-construction for a fraction of what the change order costs.
Understanding where these change orders come from allows GCs to structure pre-construction meetings, subcontract requirements, and scope review processes to eliminate most of them before the project starts.
Substrate conditions discovered after flooring mobilization
The most expensive flooring change order category on multifamily projects is substrate preparation that the flooring sub identifies at mobilization because no one documented substrate conditions before the floor was scheduled for installation. The flooring sub arrives, measures the slab, discovers 3/4-inch deviation over a 10-foot span at a construction joint, and submits a change request for self-leveling underlayment.
The self-leveling underlayment is probably legitimate scope. The problem is that it is being identified at mobilization, when the floor is on the schedule and the delay cost is real. If substrate conditions were documented before the floor was scheduled for installation, the GC could have included the self-leveling underlayment in the original scope or factored the cost into the project budget.
Prevention: require the flooring sub to perform and document substrate flatness and moisture measurements before mobilization is scheduled for each floor, not at mobilization. Any out-of-tolerance conditions identified at that stage can be priced and scheduled without creating a mobilization delay.
Blocking omissions discovered at Division 10 installation
Grab bars, fire extinguisher cabinets, and recessed mailbox units all require wall blocking that must be installed before drywall closes. When the Division 10 sub is not engaged before framing, or when the GC does not know to request blocking specifications from the Division 10 sub before drywall, the blocking is not there at installation. The correction requires opening the wall, installing blocking, repatching, retaping, and repainting.
On a 150-unit project with ten or twelve accessible units and a common area restroom on each floor, a grab bar blocking omission that affects every accessible location is a correction that multiplies quickly. The per-unit cost of the correction, across the total affected unit count, typically exceeds what a thorough pre-construction blocking specification process would have cost by a factor of five to ten.
Prevention: require the Division 10 sub to provide blocking location specifications, including heights and load requirements, to the GC before the framing crew advances on any accessible unit bathroom walls or common area restroom walls. Make this a contractual pre-construction deliverable, not a courtesy.
Trim kit incompatibility with installed valve bodies
Plumbing fixture trim kits are valve-specific. A faucet trim kit from one manufacturer will not fit a valve body from another. When the Division 22 fixture supply sub orders trim kits without confirming the valve brand and model from the licensed plumbing sub, the kits may arrive incompatible with the installed valve bodies. The correction requires returning the incompatible kits, reordering compatible kits, and waiting for delivery, during which the plumbing sub cannot complete trim-out on the affected floors.
Prevention: require the Division 22 sub to confirm valve brand and model from the licensed plumbing sub’s approved submittal before placing any trim kit order. Make this a pre-procurement contractual step, not a step that happens at installation when the incompatibility is discovered.
Countertop cutout errors from missing sink templates
The sink cutout in a countertop is fabricated to the specific dimensions of the specified sink model. When the countertop fabricator does not have the sink model and the manufacturer’s cutout template before fabrication begins, the fabricator either guesses at a standard cutout dimension or fabricates without a cutout at all. Both require field modification or refabrication.
Field modification on a stone countertop risks cracking the slab. Refabrication adds two weeks to the delivery schedule. Either outcome delays plumbing trim-out and the floor completion milestone.
Prevention: require the Division 22 sub to transmit the sink model number and manufacturer’s cutout template to the countertop sub before countertop fabrication begins on each unit type. Make this a pre-fabrication contractual step with written confirmation from both subs.
Shower enclosure measurement from drawing dimensions
Frameless and semi-frameless shower enclosures must be measured from the finished tile face, not from architectural drawing dimensions. Tile installation variation, even within the tolerance of a well-managed project, is enough to produce a frameless enclosure that does not fit the opening correctly if the enclosure was fabricated from drawing dimensions.
A frameless enclosure that arrives to a unit and does not fit requires refabrication at two to three weeks of lead time. During that time, the unit cannot be completed. On a floor where multiple units are affected, the floor completion milestone slips by the same lead time.
Prevention: require the Division 8 sub to confirm measurement timing as part of their pre-construction scope discussion. Measurement must occur after tile is complete and grouted, from the actual installed tile dimensions, before the fabrication order is placed.
Unit type matrix errors discovered at delivery
On multifamily projects with multiple unit types, cabinet packages, countertop edge profiles, hardware finishes, and fixture specifications may vary by unit type. When the interior finishes sub procures without confirming the full matrix against the architectural drawings, discrepancies between the matrix and the drawings produce deliveries in the wrong configuration that cannot be corrected without reordering.
Reordering cabinets, for example, adds four to six weeks of lead time on custom or semi-custom product. That delay ripples through every subsequent interior finishes trade on the affected floors and units.
Prevention: require the interior finishes sub to review the full unit type matrix against the architectural drawings and submit a written confirmation, with any discrepancies flagged, before any procurement order is placed. This review is free. The correction is not.
How Innergy’s process addresses each of these sources
Innergy’s pre-construction deliverables directly address every change order source described above. Substrate inspection is documented before flooring mobilization is scheduled. Division 10 blocking specifications are provided before framing advances. Trim kit compatibility is confirmed from the licensed plumbing sub before any kit is ordered. Sink cutout templates are transmitted to the countertop fabricator before fabrication. Shower enclosure measurement is taken from finished tile dimensions, not from drawings. The unit type matrix is reviewed and confirmed before any procurement order is placed.
These are not value-added services we offer on premium projects. They are how we run every project, because the cost of the change order they prevent is always greater than the cost of the process that prevents it.
