Multifamily Renovation: 838 Issues Found

Summary: On the Level 1 Demolition Floor Plan (A0.01), the drawings direct that the elevator be removed while keeping the opening/trim: 'RMV ELEVATOR AND CONTROLS,\nELEVATOR OPENING AND TRIM\nTO REMAIN, COORD W VT SERIES'. However, on the Level 1 Floor Plan (A2.01), the drawings indicate the elevator is to remain: 'EXG ELEVATOR TO\nREMAIN'. These...

Why it matters: This creates a construction-critical scope conflict for elevator/VT work, associated electrical controls, and architectural impacts at the elevator opening. It can lead to incorrect demolition, procurement, and sequencing (e.g., removing equipment intended to remain or leaving equipment intended to be removed).

Suggested next step: Confirm the intended scope for each Level 1 elevator: which elevator(s) (if any) are to be removed versus remain. Update A0.01 and/or A2.01 notes so elevator disposition is consistent, and confirm associated VT/electrical control work boundaries (what is removed vs what stays: cab, machinery, controls, door equipment, trim).

Summary: The civil and landscape sheets are coordinated around a site whose primary building is labeled “MCCORMICK HALL” along the Danforth Street / Memorial Drive edges, while the architectural site plan for the same street context instead labels the primary buildings as “WEST TOWER” and “EAST TOWER” with a “PODIUM” and “COURTYARD” between them. These...

Why it matters: If construction is laid out from the architectural site plan while civil/landscape work is designed around “MCCORMICK HALL,” contractors could stake/construct site improvements relative to the wrong building footprints and edges, leading to major field conflicts, rework, and potential permitting/coordination failures.

Suggested next step: Confirm which site/building configuration governs this package: (1) “MCCORMICK HALL” site improvement project or (2) “WEST TOWER / EAST TOWER” with “PODIUM/COURTYARD.” Issue corrected/updated sheets so Civil, Landscape, and Architectural plans all reference the same base plan and building names/footprints for Amherst Street, Danforth Street,...

Summary: The cover sheet identifies the drawing set as “50% CONSTRUCTION DOCUMENTS - NOT FOR CONSTRUCTION” dated “7 MARCH 2025,” while the specification set identifies itself as “100% Construction Documents – 30 May 2025.” These are conflicting issuance levels/dates between drawings and specifications.

Why it matters: This mismatch indicates the drawings and specifications may be from different project issuances, creating a high risk of pricing/constructing from an incomplete or non-permittable set, leading to bid confusion, RFIs, and potential construction delays while the correct issued-for-construction set is established.

Suggested next step: Confirm the correct issued set for contract and construction (IFC/100% date) and reissue/replace the cover sheet (and full drawing set if applicable) so the drawing issue level/date aligns with the specifications’ “100% Construction Documents – 30 May 2025.”

RFI draft: Confirm the correct issued set for contract and construction (IFC/100% date) and reissue/replace the cover sheet (and full drawing set if applicable) so the drawing issue level/date aligns with the specifications’ “100% Construction Documents – 30 May 2025.”

Summary: On sheet S0.1, the “REINFORCEMENT DEVELOPMENT & LAP SPLICE LENGTHS (TENSION ONLY)” schedule includes Class B lap splice values less than 24 inches (e.g., #4 “CLASS B SPLICE” at 5000 psi, “OTHER BARS” = 1'-11'). Specification Section 033000 states: “all vertical bars shall be lapped not less than 36 bar diameters at splices, or 24 inches,...

Why it matters: If the shorter lap lengths from the drawing schedule are used for vertical reinforcement, the work may fail special inspection/QA requirements and require invasive rework (demo/epoxy dowels/couplers), causing major cost and schedule overruns and potentially compromising structural performance.

Suggested next step: Clarify whether the S0.1 tension lap splice schedule is permitted to govern vertical bar splices. If vertical bars must comply with Section 033000 (minimum 24 inches or 36db, whichever is greater), revise the schedule/notes so no applicable listed lap splice length is less than that minimum, or explicitly state limitations on where the schedule...

Summary: Detail 1/S4.03 (AXONMETRIC - GUARDRAIL) calls out: “PUDDLE WELD BAR TO FAR SIDE OF BOT RAIL @ 4\' SPA. GRIND WELDS SMOOTH.” This indicates the vertical bar-to-bottom-rail connection is intended to be made with puddle/plug-type welds (discrete welds), rather than a continuous weld along the entire area of contact. The Exterior Metal Handrails...

Why it matters: If the guardrail is fabricated per the puddle-weld note, it may not comply with the specification’s continuous-weld workmanship/strength requirements and could be rejected during inspection, resulting in rework and schedule impacts.

Suggested next step: Confirm whether puddle/plug welding of the bar-to-bottom-rail connection (as noted on 1/S4.03) is acceptable under Section 05 7301 continuous-weld requirements. If not acceptable, revise the detail to specify continuous welds (and any required grinding/finish) consistent with the specification, or provide an explicit written deviation/approval.

If not acceptable, revise the detail to specify continuous welds (and any required grinding/finish) consistent with the specification,...

Summary: The demolition legend includes scope to remove existing ceiling finishes and explicitly includes removing 'SPRINKLER HEADS' as part of that ceiling demolition scope. The Selective Demolition specification requires maintaining fire-protection facilities in service during selective demolition operations. Removing sprinkler heads (without...

Why it matters: This conflict can create an active fire protection system impairment in an occupied/adjacent-to-occupied building area, which can trigger AHJ/fire department impairment procedures, require temporary protection, and cause schedule delays and added cost for temporary sprinklers, capping, or sequencing changes.

Suggested next step: Confirm whether sprinkler heads in areas of ceiling demolition are to be (a) temporarily removed and capped while maintaining the sprinkler system in service, (b) relocated with temporary protection provided, or (c) protected in place. Provide a detailed fire protection impairment/temporary protection plan and indicate the responsible trade and...

RFI draft: Confirm whether sprinkler heads in areas of ceiling demolition are to be (a) temporarily removed and capped while maintaining the sprinkler system in service, (b) relocated with temporary protection provided, or (c) protected in place. Provide a detailed fire protection impairment/temporary...

Summary: The demolition legend directs removal of ceiling elements including sprinkler heads, and the plan includes a callout to remove an existing fire hose cabinet. The selective demolition specification requires fire-protection facilities to be maintained in service during selective demolition operations. As drawn, removing sprinkler heads and fire...

Why it matters: If fire protection is impaired without an approved plan, the Owner’s operations and life safety can be impacted, and the AHJ/Owner may stop work until fire protection is restored, creating schedule delays and added cost for temporary measures installed reactively.

Suggested next step: Provide the required sequence and temporary fire protection approach for areas where ceiling demo removes “SPRINKLER HEADS” and where “RMV EXG FIRE HOSE AND CABINET” is indicated. Confirm how fire-protection facilities will be maintained in service (e.g., temporary heads, caps, isolation zones, fire watch, impairment permitting/notifications)...

Confirm how fire-protection facilities will be maintained in service (e.g., temporary heads, caps, isolation zones,...

Summary: The demolition ceiling legend indicates that when ceiling demolition occurs, it includes removal of existing sprinkler heads. The Selective Demolition specification requires maintaining fire-protection facilities in service during selective demolition operations. The drawing instruction to remove sprinkler heads directly conflicts with the...

Why it matters: If sprinkler heads are removed without an approved temporary protection/sequence, the fire protection system (or zones) may have to be taken out of service, which can trigger safety noncompliance and jobsite shutdowns, and can also require additional temporary work not clearly defined in the demolition scope, creating schedule and cost impacts.

Suggested next step: Confirm the intended fire-protection approach in areas with ceiling demolition: Are sprinkler heads to be removed, temporarily removed and reinstalled, or protected in place? Provide the required means/sequence to “Maintain fire-protection facilities in service during selective demolition operations,” and revise the demolition legend/notes...

Provide the required means/sequence to “Maintain fire-protection facilities in service during selective demolition...

Summary: The demolition RCP legend explicitly includes “SPRINKLER HEADS” in the ceiling removal scope. The Selective Demolition specification requires maintaining fire-protection facilities in service during selective demolition operations. If sprinkler heads are to be removed/relocated as part of the ceiling demolition, the demolition sequencing and...

Why it matters: Removing or disconnecting sprinkler heads during demolition can reduce or eliminate fire-protection coverage in the affected area unless temporary sprinklers, temporary piping, or an approved impairment plan and shutdown coordination are implemented. This is a life-safety/code compliance risk and can impact schedule and cost if not planned and...

Suggested next step: Confirm the intended demolition sequencing and fire-protection impairment/temporary protection plan for areas where the demolition RCP indicates sprinkler heads are to be removed/relocated. Provide direction/details for maintaining fire-protection facilities in service during demolition (e.g., temporary sprinklers, temporary piping/heads, or...

Summary: The building section shows West Tower level datum “WEST LEVEL 8 74' - 0'” and “LEVEL 1 0' - 0'”, indicating Level 8 is 74 feet above Level 1 in the architectural datum (and the drawing also shows a Basement datum below Level 1). The elevator specification for the West tower increase-travel project defines elevator “Travel in Feet” as “63'-0'...

Why it matters: If the elevator modernization/extension is designed and permitted per the specified 72'-0' total travel, but the architectural level datums require serving a higher elevation at the 8th floor, the elevator hoistway/rail extension and equipment layout may not coordinate with actual landing elevations. This can drive redesign, re-permitting, or...

Suggested next step: Confirm the required elevator terminal landing elevations for West Tower (Basement through 8th floor) and reconcile the elevator “Travel in Feet … = 72'-0' Total” requirement with the architectural level datums shown (including “WEST LEVEL 8 74' - 0'” and “LEVEL 1 0' - 0'”). Revise either the elevator travel requirement or the architectural...

Revise either the...

Summary: The typical shower section detail at the quartz threshold shows a vertical dimension of '+/- 3 1/4\'' at the threshold/curb condition. Section 09 3000 limits threshold height to 1/2 inch or less above adjacent floor surface, so the indicated threshold/curb height conflicts with the specification requirement.

Why it matters: If built as detailed, the threshold would not comply with the specification and would likely require demolition and reconstruction of the threshold/adjacent tile work to achieve the required height, causing significant delay and cost.

Suggested next step: Confirm the required quartz threshold height at shower entries and revise the detail to comply with the Section 09 3000 threshold height limit (or provide a documented exception/scope clarification if this element is not intended to be treated as a threshold under Section 09 3000).

RFI draft: Confirm the required quartz threshold height at shower entries and revise the detail to comply with the Section 09 3000 threshold height limit (or provide a documented exception/scope clarification if this element is not intended to be treated as a threshold under Section 09 3000).

Summary: The Type 23A elevator machine room sign detail shows the message lines including “NO STORAGE ALLOWED” called out as “1/2' TEXT,” and the wording shown differs from the specification-required text (including the required “MASSACHUSETTS-LICENSED” wording and the specified phrasing with hyphens). The elevator specification requires machine room...

Why it matters: Noncompliant elevator machine room access door signage can be rejected by the AHJ/state elevator inspection, requiring re-fabrication and re-installation and potentially delaying elevator sign-off/turnover.

Suggested next step: Revise the Type 23A machine room door sign to match the specification wording exactly and confirm all text (including “NO STORAGE ALLOWED”) is minimum 3/4' high with contrasting color. Provide the updated sign artwork/detail for review.

RFI draft: Revise the Type 23A machine room door sign to match the specification wording exactly and confirm all text (including “NO STORAGE ALLOWED”) is minimum 3/4' high with contrasting color. Provide the updated sign artwork/detail for review.

Summary: The drawing identifies the replacement machine as a “GEARED DRIVE MACHINE,” while the specification for East PE2 requires a new “Gearless ACPM” machine. This is a direct equipment-type conflict (geared vs. gearless).

Why it matters: This discrepancy affects elevator engineering (machine selection, loads/supports, controls integration, and submittals). If not resolved before procurement/coordination, it can cause major redesign, long-lead ordering impacts, and installation delays/cost overruns.

Suggested next step: Confirm the required hoisting machine type for East PE2. Revise the drawings to match the specification requirement for a new basement gearless ACPM machine (or issue a spec deviation/addendum if a geared machine is intended).

RFI draft: Confirm the required hoisting machine type for East PE2. Revise the drawings to match the specification requirement for a new basement gearless ACPM machine (or issue a spec deviation/addendum if a geared machine is intended).

Summary: The Plumbing Pump/Interceptor Schedule specifies the oil interceptor as a 'POLYETHYLENE OIL INTERCEPTOR'. Section 22 1323 requires oil interceptors to be factory-fabricated with a 'cast-iron or steel body and cover'. This is a direct material conflict with the specification.

Why it matters: A polyethylene interceptor in lieu of the specified cast-iron/steel body and cover can create procurement/approval issues (including AHJ acceptance and required load-rated cover requirements in the spec), and may require redesign/re-submittals, delaying installation and commissioning.

Suggested next step: Confirm whether the oil interceptor is required to comply with Section 22 1323 (cast-iron or steel body and cover). If so, revise the schedule to a compliant interceptor (or issue a formal spec deviation/approved substitution identifying compliant materials, cover loading, and accepted plumbing products approval).

RFI draft: Confirm whether the oil interceptor is required to comply with Section 22 1323 (cast-iron or steel body and cover). If so, revise the schedule to a compliant interceptor (or issue a formal spec deviation/approved substitution identifying compliant materials, cover loading, and accepted plumbing...

Summary: The condenser unit schedule explicitly lists the refrigerant type as R32 for the ACCU systems. The project specification for Section 23 2300 lists R-410A as the refrigerant. The drawing note also states that 'R-410 EQUIPMENT IS ACCEPTABLE IF IT CAN BE PROCURED,' which contradicts the specification requirement that identifies R-410A as the...

Why it matters: A refrigerant change affects equipment selection, code compliance requirements (ASHRAE 15 implications), refrigerant piping design/compatibility, testing requirements, and commissioning. If procurement proceeds with R32 equipment while the contract specification requires R-410A, this will likely trigger submittal rejection, redesign/review...

Suggested next step: Confirm the required refrigerant for the project: maintain compliance with Section 23 2300 (R-410A) or issue a formal specification revision/approved substitution to allow R32, including any required updates to refrigerant piping requirements, testing/commissioning, and associated schedules/notes.

RFI draft: Confirm the required refrigerant for the project: maintain compliance with Section 23 2300 (R-410A) or issue a formal specification revision/approved substitution to allow R32, including any required updates to refrigerant piping requirements, testing/commissioning, and associated schedules/notes.
