Interior finishes scope gaps are the change orders that GCs generate on almost every multifamily project and that experienced finishes subs know to watch for when reviewing bid documents. Some gaps are genuine specification omissions that the architect did not intend. Others are items that the GC assumed were included in one trade’s scope when they were actually in another’s, or in no one’s. Most are preventable with a careful bid document review and a clear scope inclusion list in the finishes subcontract.
Understanding which scope items are most commonly omitted, why they are omitted, and what specification language closes each gap before the project starts reduces the volume of finishes-related change orders on every project.
1. Knox box location and fire authority coordination
Knox boxes, the key storage boxes mounted at building entries for fire department access, are consistently omitted from interior finishes bid documents because they fall between the Division 10 accessories scope and the fire protection scope. The Knox box is a Division 10 product but the location must be approved by the local fire authority before installation, and the approval process takes four to six weeks.
Prevention: explicitly include Knox box supply and fire authority coordination in the Division 10 scope in the subcontract. Require the Division 10 sub to initiate Knox box location approval with the applicable fire authority at least six weeks before the projected occupancy inspection.
2. 4C mailbox USPS approval and rough opening coordination
USPS Form 4298 approval for 4C mailboxes takes four to six weeks and must be obtained before the mailbox is installed. The rough opening dimensions must be provided to the GC before framing advances on the mailbox alcove wall. Both of these requirements are missed when the mailbox scope is added to a Division 10 bid document as a line item without the coordination language that defines when the sub must initiate the approval process.
Prevention: include USPS coordination initiation as a pre-construction deliverable with a specific deadline in the Division 10 subcontract. Require the rough opening dimensions as a pre-framing deliverable.
3. Shower door measurement and lead time
Shower door and frameless glass enclosure measurement cannot occur until tile is set and grouted. The fabrication lead time after measurement is two to three weeks for frameless and one to two weeks for semi-frameless. When this lead time is not accounted for in the project schedule, shower door installation falls on the critical path after occupancy is already scheduled.
Prevention: include shower door measurement timing and fabrication lead time explicitly in the Division 8 subcontract and in the master schedule. Flag the shower door lead time to the superintendent at pre-construction so the tile sequencing accounts for it.
4. Wire shelving in linen closets
Wire shelving specifications frequently identify primary bedroom closets but omit linen closets, pantry closets, and utility closets. Residents expect shelving in every storage space. When the specification omits linen closets, either the GC absorbs a change order or the units deliver without shelving in a location that residents immediately notice.
Prevention: explicitly list every closet and storage space in the wire shelving scope, including linen closets, pantry closets, coat closets, and utility closets. Identify the number of shelves required in each.
5. Base installation after flooring
Wall base, whether vinyl cove base or painted MDF base, is often omitted from the flooring scope and included in the paint scope as a painted surface, or from both scopes without explicit assignment. The installation sequence creates the assignment problem: base installs after flooring in the correct sequence, which puts it temporally in the flooring crew’s work period, but it may be in the paint scope as a painted element.
Prevention: explicitly assign wall base installation to a specific trade in the subcontract and confirm the assignment does not create a gap or duplication with the paint scope.
6. Threshold and transition strip installation
Transition strips at flooring material changes and thresholds at unit entry doors are consistently omitted from flooring specifications or under-specified as “transitions as required.” A 200-unit project may have 400 to 600 transition strip installations depending on unit configuration. Specifying “as required” without identifying the number and type allows bidders to price zero and change-order the actual scope.
Prevention: include transition strip counts by type in the flooring specification and confirm the count in the subcontract bid review before award.
7. Mirror installation above vanities
Vanity mirrors in multifamily bathrooms are a Division 8 scope item that is frequently omitted when the project specifies framed mirrors or beveled plate mirrors without explicitly assigning the installation to the Division 8 sub. The mirror supply is in Division 8 but the installation may be unclear.
Prevention: explicitly include mirror supply and installation in the Division 8 scope, including the mounting method and the height from the finished floor to the bottom of the mirror.
8. Appliance installation versus supply
When appliances are supplied by the developer and installed by a finishes sub, the installation scope must be explicitly assigned. When appliances are supplied and installed by the appliance manufacturer’s installer, the finishes sub’s scope boundary must exclude appliance installation explicitly. Gap: when neither the developer nor the GC has confirmed which arrangement applies, appliance installation either falls through or is double-assigned.
Prevention: confirm appliance supply and installation assignment in writing with the developer before finalizing any finishes subcontract scope.
9. Toilet seat supply
Toilet seats are frequently not included in the plumbing specialties scope because they are not installed by the licensed plumbing sub and may not be included in the Division 22 supply scope either. Units that complete with a toilet and no seat are a leasing and occupancy problem.
Prevention: explicitly include toilet seat supply in the Division 22 fixture supply scope or in the Division 10 accessories scope. Confirm the assignment with both subs.
10. Shower curtain rods in non-glass shower applications
In affordable and workforce housing where shower curtains are used instead of glass enclosures, the shower curtain rod is often omitted from the Division 8 scope because the specification focuses on glass enclosures. Units that complete with a tub and shower combination but no curtain rod cannot be occupied.
Prevention: explicitly include shower curtain rod supply and installation in the Division 8 scope for any unit type with a tub-and-shower combination.
How Innergy prevents scope gaps
Innergy covers Division 6-Finish Carpentry & Cabinets, Division 9-Flooring, and Division 10-Specialties for multifamily construction under a single subcontract.
Innergy reviews the bid documents for each project and identifies scope items that are not explicitly assigned before we submit our bid. We include identified gaps in our bid clarifications and price the scope into our bid rather than excluding it and submitting a change order after award.
