04 / QUESTIONS BEFORE RELEASE
The gaps stay visible.
Ten recorded coordination questions. No approved replacement design, final product selection or settled field dimensions are implied.
EF-1(N) on floor plan/schedule versus EF-2(N) on roof plan
Confirm single new fan tag and location before ordering.
M101 / M102 / M401Floor exhaust grilles 875 + 585 = 1,460 CFM versus fan 1,500 CFM; toilet E-2 shows 40 versus 75 CFM balance
Engineer to issue corrected outlet and exhaust balancing values.
M101 / M401Air-balance total supply row 2,400 CFM conflicts with 2,630 CFM RTU, ventilation table and 14 supply devices
Use 2,630 as documented sum for review; request corrected schedule, no redesign implied.
M401 / M101M101: 10 ft main acoustic lining versus M301: all return + first 15 ft supply
Confirm lining extent, thickness and final clear-inside duct dimensions.
M101 / M301M101: 8 in retail branches at 280 CFM versus M401 neck-size table 10 in for 201-400 CFM
Engineer/shop drawings to reconcile; do not silently resize measured branches.
M101 / M401No duct centerline elevations or roof/deck height supplied in reviewed plans
Measure roof and ceiling heights, vertical rises, offsets and all crossing clearances.
M101 / M102New duct base scope versus note offering existing-duct reuse after approval
Base quote new ducts; quote approved reuse as separate alternate.
M101Fan timeclock, lighting, RTU interlocks and occupied schedule note overlap
Agree final control matrix and trade responsibility.
M401 / E101Roof openings require landlord/owner roofing coordination; roof elevation and condition absent
Field verify intake/exhaust 10 ft separations, curb supports and flashings; structural engineer review as required.
M000 / M102Scheduled S-2 12 x 12 in face and TMS-AA designation need an exact product selection.
Confirm material, frame, module and exact model with engineer and supplier. Keep the scheduled face and count pending clarification.

What has been checked
The recorded run lengths reconcile to calibrated route coordinates and the later duct schedule. The source floor plan and equipment schedules were inspected. Three supply mains (28 × 14, 16 × 12 and 14 × 10 in) were separately compared with original PDF outline geometry.
What remains open
- Horizontal centerlines are measured at the printed 1/4 in = 1 ft source scale. Verticals, offsets, fabrication fitting quantities and field routing are not settled.
- Insulation area uses clear-inside duct perimeter and horizontal length. Final outside dimensions, fitting surfaces, verticals and procurement waste remain open.
- LS means a lump-sum scope package, not a measured item count. Assembly counts do not establish a vertical length.
- Existing equipment and retained duct are identified separately and are not new purchases. Detailed equipment and terminal schedules expand the scope rows; do not add their counts twice.
- No procurement waste factor has been applied. No supplier quotes, labor rates or project bid prices are published.
- Source-route review and quantity arithmetic have been checked. Complete independent remeasurement of every route and resolution of the open questions are still required for bid release.
Original client drawings, identities, addresses, rates and quotes remain private. This public schedule contains the available quantities and questions for the matching model.
