Post-Construction Cleaning & Closeout Checklist: 3-Phase Turnover, Surface Chemistry, Punch List & O&M Handover

Peeling temporary floor protection after its UV adhesive cure window expires, scraping tempered curtain wall glass with a broad razor blade, or requesting the Architect’s walkthrough before the general contractor’s pre-punch is complete causes permanent finish damage, rejected inspections, and frozen retainage. Post construction cleaning and project turnover follow a three-phase physical and contractual closeout sequence under CSI Division 01 74 23 and AIA A201-2017 §9.8 that synchronizes dust-controlled substrate detailing, rolling punch-list resolution, and administrative O&M and lien-waiver handoffs.

Post construction cleaning and project closeout follow a three-phase physical and contractual sequence under UFGS 01 78 00 Closeout Submittals (CSI Division 01 74 23 and 01 77 00) and AIA Document A201-2017 §9.8: Phase 1 rough debris removal, Phase 2 detail cleaning with pH-neutral surface protection before the Architect’s Substantial Completion punch list walkthrough, and Phase 3 white-glove turnover cleaning alongside O&M manuals, as-built drawings, and AIA G704/G706/G707 closeout affidavits.

This field guide sits in the Planning collection, connects to all construction guides, and picks up directly where the construction project coordination checklist concludes weekly trade lookaheads and overhead plenum sign-offs.

1. Three-Phase Post-Construction Cleaning Specification (CSI 01 74 23 & FAR 52.236-12)

Single-pass cleaning at the end of a commercial build fails because fine gypsum and crystalline silica particulates settle out of the air column over multiple days, while curing mortar and acrylic masking adhesives chemically bond to substrates if left past their dwell limits. Under CSI MasterFormat Section 01 74 23 (Final Cleaning), UFGS 01 78 00 Closeout Submittals, and FAR 52.236-12 Cleaning Up, professional post construction cleaning is divided into three distinct field mobilizations tied to schedule hold points.

Phase 1: Rough Clean (Pre-Paint & Pre-Flooring Substrate Preparation)

• Schedule Trigger: Mobilize immediately after structural framing, overhead MEP rough-in, through-penetration firestopping, and drywall hanging/taping/sanding conclude—before prime painting, ceiling tile installation, or finished flooring begins.
• Bulk Debris & Subfloor Preparation (29 CFR 1926.25): Under OSHA 29 CFR 1926.25 Housekeeping, remove all scrap lumber, drywall offcuts, banding straps, cable spools, and combustible packaging from floors, corridors, and egress stairs. Scrape dried joint compound and fireproofing overspray flat off concrete slabs and wood subfloors without gouging underslab vapor barriers or acoustic mat membranes.
• Mandatory Silica HEPA Vacuuming (29 CFR 1926.1153(f)): Under OSHA’s Respirable Crystalline Silica standard (29 CFR 1926.1153(f)), dry sweeping, dry brushing, or blowing down concrete, mortar, stone, or drywall dust with uncaptured compressed air is strictly prohibited. Crews must use industrial HEPA-filtered vacuums (99.97% capture efficiency at 0.3 microns) or wet-sweeping compounds to vacuum bottom metal stud tracks, window sill channels, floor expansion joints, and open electrical outlet boxes so hidden dust does not blow back onto wet paint when wallplates and base trim are installed.
• HVAC Return Boot Sealing (SMACNA IAQ): Verify that all return-air ductwork boots and transfer openings remain sealed with polyethylene sheeting or temporary MERV 8 filter media throughout drywall sanding and Phase 1 rough cleaning.

Phase 2: Light / Final Detail Clean (Pre-Substantial Completion Walkthrough)

• Schedule Trigger: Execute after acoustical ceiling grids, light fixtures, architectural millwork, interior/exterior glazing, plumbing fixtures, and finished floors are installed—completed 24 to 48 hours prior to the Architect’s AIA A201 §9.8.3 Substantial Completion inspection.
• Temporary Protection Stripping & UV Dwell Limits: Peel breathable floor protection board (Ram Board or Skudo), self-adhesive carpet protection film, factory laser-film on stainless steel, and blue/green painter’s masking tape. Most acrylic masking tapes and protective films carry a 14-to-60-day maximum UV and solar-heat dwell rating; leaving tape on curtain wall mullions or factory millwork beyond that window cross-links the adhesive polymer into a hardened residue that requires solvent stripping. Leaving non-breathable polyethylene sheet over curing concrete or natural stone traps moisture vapor, inducing sub-surface efflorescence, spalling, or wood floor cupping.
• HVAC Plenum Vacuuming & Permanent MERV 13 Filter Swap: Before starting continuous mechanical conditioning or certified Testing, Adjusting, and Balancing (TAB), vacuum terminal VAV boxes and fan-coil plenums, wipe supply diffusers and return grilles, remove temporary construction filters (MERV 8), and install clean permanent MERV 13 filtration media. Running air-handling units during or after drywall finishing without a clean filter swap pulls fine calcium-sulfate and silica dust into wet cooling coils, cementing fin channels shut and voiding mechanical equipment warranties.
• Fixture, Millwork & Glazing Detailing: Vacuum inside every cabinet box, drawer slide, and concealed Euro-hinge cup; remove manufacturer barcode stickers using non-etching citrus or isopropyl release agents; descale and sanitize vitreous china plumbing fixtures; wash interior and exterior glazing per GANA 01-0300; and auto-scrub or damp-mop hard flooring.

Phase 3: Touch-Up / White-Glove Turnover Clean (Post-Punch & Dust Settling Window)

• Schedule Trigger: Mobilize only after all punch-list trades have completed corrective work and exited the zone, and after a mandatory 48-to-72-hour airborne dust settling window with the permanent HVAC system operating continuously through clean MERV 13 filters.
• Particulate Settling Mechanics & White-Glove Execution: Fine gypsum and silica particles (1 to 10 microns aerodynamic diameter) disturbed during punch-list ceiling tile access and wall touch-ups remain suspended in room air for 48 to 72 hours. If a crew performs final wipe-downs the same afternoon punch painters leave, a visible grey film re-deposits across dark millwork and glass within two days. After the 48-to-72-hour settling hold, Phase 3 crews use damp microfiber cloths and backpack HEPA vacuums to wipe all horizontal ledges top-down (door tops, light troffer lenses, window sills, countertops), buff out trade boot scuffs, polish entry hardware, and lock each room door prior to Owner key handover.

Rule of thumb: Never authorize Phase 3 Touch-Up Cleaning until punch-list trades are 100% out of the building zone and the permanent HVAC system has scrubbed room air through clean MERV 13 filters for at least 48 consecutive hours.

Equation: Three-Phase Cleaning Crew-Hour & Budget Sizing

Estimators and project managers size post construction cleaning labor and subcontract budgets by summing the reciprocal production rates across each required mobilization phase:

Formula: Total Crew-Hours (H_total) = Gross Floor Area (A_sf) × [ (1 / R_phase1) + (1 / R_phase2) + (1 / R_phase3) ]

Worked Example: A general contractor is scheduling turnover for a 45,000 SF commercial office tenant improvement (TI) requiring all three CSI 01 74 23 phases. Based on fixture density and interior glass partitions, the estimator selects mid-band production rates of R_phase1 = 500 SF/hr, R_phase2 = 225 SF/hr, and R_phase3 = 600 SF/hr at a fully burdened cleaning labor rate of $48.00 / hr (plus $2,100 for HEPA vacuum consumables, neutral surfactants, and lift rental):

Calculation:

• Phase 1 Rough Clean Hours = 45,000 SF / 500 SF/hr = 90.0 crew-hrs
• Phase 2 Final Detail Clean Hours = 45,000 SF / 225 SF/hr = 200.0 crew-hrs
• Phase 3 White-Glove Turnover Hours = 45,000 SF / 600 SF/hr = 75.0 crew-hrs
• Total Cleaning Labor (H_total) = 90.0 + 200.0 + 75.0 = 365.0 crew-hrs (Blended rate: 45,000 / 365 = 123.3 SF/hr)
• Total Subcontract Cost = (365.0 hrs × $48.00/hr) + $2,100 = $17,520 + $2,100 = $19,620 ($0.436 / SF)

To finish the 200.0-crew-hour Phase 2 Final Clean inside a 2-day (16-working-hour) schedule window ahead of the Architect’s walkthrough, the cleaning subcontractor must staff a dedicated crew of 200.0 / 16 = 12.5 → 13 cleaners.

Takeaway: Budget and schedule all three CSI 01 74 23 cleaning phases separately; enforce 29 CFR 1926.1153 HEPA vacuuming in Phase 1, swap MERV 13 filters before Phase 2, and hold a 48-to-72-hour dust settling window before Phase 3.

2. Architectural Surface Chemical Compatibility & Cleaning Contraindications

Improper chemical selection or aggressive scraping during Phase 2 Final Clean is the single largest source of late-stage backcharges during project closeout. A single laborer using an acidic tile-haze remover on honed limestone or dragging a 4-inch razor scraper across tempered curtain wall lites can destroy $50,000+ of architectural finishes in an afternoon. Enforce the governing industry chemical and tooling standards across all five high-risk building substrates.

1. Anodized & PVDF / Kynar-500 Architectural Aluminum (FGIA / AAMA 609 & 610-15)

Under FGIA / AAMA 609 & 610-15 (Cleaning and Maintenance Guide for Architecturally Finished Aluminum), curtain wall mullions, storefront frames, and metal rainscreen panels finished with architectural Class I anodizing (AAMA 611) or 70% PVDF fluoropolymer coatings (AAMA 2605) must be washed strictly with clean water and mild, pH-neutral non-ionic detergents (pH 6.0 to 8.0).

• Thermal & Rinsing Protocol: Clean shaded elevations when metal surface temperatures are moderate (< 100°F / 38°C); applying soap to sun-baked aluminum flashes the water carrier off instantaneously and bakes permanent surfactant streaks into the coating.
• Dominant Failure Mode & Contraindications: Strictly prohibit alkaline mortar washes, trisodium phosphate (TSP), muriatic or hydrofluoric acid masonry cleaners, brass/steel wire brushes, abrasive scouring pads, and ketone solvents (MEK, acetone, lacquer thinner). Strong alkalies and acids chemically dissolve the 0.7-mil anodic oxide barrier into chalky white blooms, while ketones soften PVDF fluoropolymer resin and swell perimeter silicone weatherseal joints.

2. Calcareous Natural Stone & Cementitious Terrazzo (Natural Stone Institute / MIA)

Under Natural Stone Institute (formerly Marble Institute of America) post-construction care standards, architectural stone is divided between siliceous stone (granite, slate, sandstone) and calcareous stone—including marble, travertine, limestone, onyx, and Portland-cement marble-chip terrazzo—which is composed primarily of calcium carbonate (CaCO3).

• Dominant Failure Mode & Contraindications: Strictly prohibit any acidic cleaner (pH < 7.0) on calcareous stone or terrazzo—including muriatic (HCl) acid, sulfamic acid, phosphoric acid, vinegar, lemon/citrus cleaners, and standard ceramic-tile acidic grout-haze removers. Acid reacts instantaneously with calcium carbonate (CaCO3 + 2H+ → Ca2+ + H2O + CO2), evolving carbon dioxide gas, dissolving the polished mineral crystal faces into dull white etch marks, and pitting cementitious grout joints.
• Approved Protocol: Scrub exclusively with a pH-neutral (pH 7.0 to 8.0) non-ionic stone surfactant diluted in warm water using soft bristle brushes or white non-abrasive pads, extract slurry immediately with a wet vacuum, and allow the stone substrate to dry thoroughly before applying breathable fluorochemical or siloxane penetrating sealers.

3. Heat-Treated / Tempered & Low-E Coated Glass (GANA Bulletin 01-0300)

Under GANA Glass Informational Bulletin 01-0300 (Proper Procedures for Cleaning Architectural Glass Products), general contractors must prohibit window-cleaning crews from using broad metal razor blades or steel putty knives across entire glass lites—especially heat-strengthened, tempered, and pyrolytic or sputter-coated Low-E insulating glass units (IGUs).

• Dominant Failure Mode (“Roller Pickup” Scratching): When flat glass is heated to ~1,150°F (620°C) inside a horizontal tempering furnace, microscopic silica particles from the ceramic hearth rollers fuse onto the bottom surface of the glass lite (“roller pickup”). When a cleaner drags a wide metal razor blade across the tempered lite, the steel edge snaps those microscopic fused glass nodes loose, traps them alongside airborne quartz drywall/mortar grit underneath the blade, and drags hundreds of permanent comet-tail scratches across the vision glass—voiding the glass fabricator’s warranty.
• Approved Protocol: Flood the glass surface generously with clean water first to float off abrasive construction grit; wash with mild neutral soap or a 50/50 isopropyl alcohol and water solution using a microfiber sleeve and rubber squeegee; and remove localized mortar or paint dots individually by soaking them first and lifting each softened spot with a plastic or nylon scraper.

4. Architectural Stainless Steel (Type 304 / Type 316 — ASTM A380 / SSINA)

Elevator cab doors, monumental stair railings, and restroom accessories rely on a self-healing passive chromium-oxide (Cr2O3) surface film.

• Dominant Failure Mode (Chloride Vapor Pitting & Rouging): Strictly prohibit sodium hypochlorite (household bleach), muriatic/hydrochloric acid liquid, and carbon-steel wool. Crucially, even if muriatic acid never touches stainless steel directly, volatilized hydrochloric acid fumes drifting from nearby ceramic floor tile acid-washing condense onto elevator doors and handrails, penetrating the passive Cr2O3 film and triggering widespread brown chloride pitting corrosion overnight. Carbon-steel wool embeds microscopic free-iron particles into the stainless grain that rust upon exposure to humidity (“rouging”).
• Approved Protocol: Wipe strictly parallel to the #4 brushed polish grain line using clean water, a non-chloride neutral cleaner, and lint-free microfiber cloths, then buff dry.

5. Densified Polished Concrete & Resinous Epoxy Flooring (ACI 302.1R / CPAA)

Clean lithium- or sodium-silicate densified polished concrete slabs and epoxy/polyaspartic floors using a walk-behind auto-scrubber fitted with soft white or red non-abrasive pads (or soft nylon brushes) and a pH-neutral floor conditioner (pH 7.0 to 8.5) with immediate squeegee vacuum pickup. Never apply acidic concrete etchers (pH < 5.0), high-alkaline butyl degreasers or floor strippers (pH > 11.0), or aggressive black/green stripping pads that chemically degrade calcium-silicate-hydrate (CSH) gloss and micro-scratch resinous topcoats.

Takeaway: Require written chemical SDS approval before Phase 2 mobilization; enforce pH 6.0–8.5 neutral detergents on aluminum, stone, and polished slabs, ban metal razor scrapers on tempered glass (GANA 01-0300), and ban muriatic acid and bleach anywhere near stainless steel.

3. Substantial Completion & Punch List Execution (AIA A201 §9.8, AIA G704 & ASTM C840)

Physical cleaning and quality verification converge at the substantial completion punch list gate. Connecting in-progress stage inspections from the construction quality control checklist and the project-wide construction quality control plan to contractual closeout requires following the exact procedural sequence in AIA Document A201-2017 §9.8 (see our AIA contract documents procurement guide for how A201 binds prime agreements A101, A102, and A133).

Step 1: Contractor’s Comprehensive Pre-Punch List (AIA A201 §9.8.2)

Under AIA A201-2017 §9.8.2, when the Contractor considers that the Work (or a designated portion thereof) is substantially complete, the Contractor must first prepare and submit to the Architect a comprehensive list of items to be completed or corrected prior to final payment.

• Dominant Failure Mode (Premature Walkthrough Rejection): Calling the Architect and Owner for a Substantial Completion walkthrough before the GC superintendent and trade foremen have run their own room-by-room pre-punch—and before Phase 2 Final Clean is complete—results in the Architect terminating the walkthrough under §9.8.3 and backcharging the Contractor for additional architectural re-inspection services. Furthermore, §9.8.2 explicitly states that failure to include an item on the Contractor’s punch list does not alter the responsibility of the Contractor to complete all Work in accordance with the Contract Documents.

Step 2: Room-by-Room Top-Down Rolling Punch Sequence & ASTM C840 Lighting Rule

To prevent overhead punch repairs from dropping ceiling dust or paint splatters onto finished floors, inspect and sign off every room in a strict top-down, clockwise geometric sequence:

1. Above-Ceiling Plenum Pre-Cover Sign-Off: Before dropping final acoustic ceiling tiles, verify that all IBC Section 714 firestop penetration labels are affixed, seismic splay wires and compression struts are taut, chilled-water insulation vapor seals are continuous, and electrical junction box covers are screwed shut.
2. Suspended Ceiling Grid & Overhead Fixtures: Check 2×2 or 2×4 acoustical ceiling tile (ACT) grid laser levelness, verify clean factory-cut perimeter tiles without sag or handprints, confirm fire sprinkler escutcheon rings sit flush, and test 90-minute emergency egress luminaire battery transfer.
3. Walls, Drywall Finish & Paint Inspection Lighting (ASTM C840 / GA-214 / PDCA P1): Under ASTM C840 (Standard Specification for Application and Finishing of Gypsum Board) and Gypsum Association GA-214, drywall finishing (Level 4 and Level 5) and painted wall surfaces must be inspected under normal occupancy design lighting from a perpendicular viewing distance of 5 feet (1.5 meters). Holding a high-lumen handheld LED or halogen work light obliquely flush against the wall surface (“raking light inspection”) is explicitly prohibited by ASTM C840 and GA-214, as oblique raking light magnifies sub-millimeter roller stipple outside industry tolerances.
4. Doors, Frames, Glazing & Hardware (NFPA 80 & ADA): Confirm fire-rated doors self-close and positively latch from a 12-inch open release (NFPA 80), verify perimeter clearances (≤ 1/8 in. at jambs/heads for steel doors), check interior hinged door opening force (≤ 5 lbf per ADA standards), and verify permanent key cores and access-control strikes.
5. Millwork, Plumbing Fixtures & Flooring Transitions: Verify ADA lavatory knee clearance (27 in. minimum height) and insulated P-trap/supply wraps, test GFCI receptacle trip within 6 feet of wet sinks, inspect continuous sanitary silicone sealant beads at backsplashes and floor base, and verify flush floor transition strips without lippage (≤ 1/4 in. vertical change without bevel per ADA).

Rule of thumb: Never allow a punch-list walkthrough to be conducted with handheld oblique raking lights or before permanent room lighting is energized; evaluate wall and ceiling finishes strictly at a 5-foot (1.5 m) perpendicular distance under normal occupancy illumination per ASTM C840 and GA-214.

Step 3: IBC Section 111 TCO/CO & AIA G704 Certificate of Substantial Completion

Once the Authority Having Jurisdiction (AHJ) Building Official completes final life-safety, fire alarm (NFPA 72), fire sprinkler (NFPA 13), elevator, and accessibility inspections—and verifies that all IBC Chapter 17 special inspection final reports are closed—the Building Official issues a Temporary Certificate of Occupancy (TCO under IBC Section 111.3) or final Certificate of Occupancy (CO under IBC Section 111.1).

Following verification walkthrough sign-off, the Architect issues AIA Document G704-2017 (Certificate of Substantial Completion). Executing AIA G704 triggers five simultaneous contractual and financial shifts:

1. Stops Liquidated Damages: Locks the official Date of Substantial Completion, halting daily delay liquidated damages exposure under the prime contract.
2. Transfers Building Operations, Utilities & Insurance (§9.8.4): Transfers responsibility for building security, mechanical conditioning, utilities (electricity, gas, water), routine maintenance, and property insurance coverage from the Contractor to the Owner on the date stipulated in G704.
3. Starts the 1-Year Correction Period & Warranties (§12.2.2): Starts the clock on the Contractor’s one-year obligation to correct non-conforming Work (AIA A201 §12.2.2.1) and initiates standard manufacturer equipment and workmanship warranties (unless a specific deferred warranty start date is recorded on G704).
4. Sets the Fixed Punch-List Completion Window: Establishes the binding calendar deadline (commonly 30 calendar days) within which the Contractor must complete all items on the attached punch list.
5. Releases Base Retainage Less Monetized Punch List Holdback (§9.8.5): Upon execution of G704 (and consent of surety where applicable), the Owner releases accrued contract retainage (5% to 10%), holding back only a monetized punch-list reserve equal to 150% to 200% of the Architect’s estimated value of incomplete punch-list work plus any unsettled claims.

Equation: Substantial Completion Retainage Release & Monetized Holdback (AIA A201 §9.8.5)

Formula: Net Retainage Released at G704 = (C_adjusted × r_retainage) − (M_holdback × V_punch) − H_claims

Worked Example: A general contractor reaches Substantial Completion on an $8,400,000 adjusted commercial contract (C_adjusted) where the Owner has withheld 5.0% retainage (r_retainage = 0.05), totaling $420,000 in accrued retainage. The Architect’s attached AIA G704 punch list contains 42 open deficiency items with an Architect-certified completion value of V_punch = $38,000, the contract specifies a 200% (M_holdback = 2.00) punch-list holdback multiplier, and there is $0 in unsettled subcontractor lien claims (H_claims = $0):

Calculation:

• Total Accrued Retainage = $8,400,000 × 0.05 = $420,000
• Monetized Punch List Holdback = 2.00 × $38,000 = $76,000
• Net Retainage Released upon AIA G704 Execution = $420,000 − $76,000 − $0 = $344,000

The remaining $76,000 holdback is paid upon 100% punch-list sign-off, Phase 3 Touch-Up Cleaning, and submission of the Final Payment closeout package under AIA A201 §9.10.

Takeaway: Complete the GC’s §9.8.2 pre-punch list and Phase 2 cleaning before inviting the Architect; secure AIA G704 and the IBC §111 TCO/CO to stop liquidated damages, transfer utility/insurance costs, and release base retainage less the 150%–200% monetized punch holdback.

4. Closeout Documentation, O&M Manuals, Attic Stock & Final Payment (CSI 01 77 00 / 01 78 23 & AIA G706/G706A/G707)

Clearing physical punch-list items in the field never unlocks Final Payment (AIA A201 §9.10.2) until the administrative construction closeout checklist deliverables are verified and accepted. Track these five closeout packages weekly during the final six weeks of OAC meetings alongside the Procurement collection closeout log:

1. Red-Line Record As-Built Drawings & BIM Turnover (CSI 01 78 39 / UFGS 01 78 00)

Convert the field superintendent’s and MEP foremen’s continuous red-line markups into clean As-Built Record Drawings and updated native CAD / Revit BIM models (LOD 350 / LOD 500 as specified). Record drawings must document exact horizontal and vertical coordinates of underground utilities, post-pour slab penetration offsets, rerouted ductwork, and concealed isolation valves, fire/smoke dampers, and sanitary cleanouts above hard gypsum ceilings.

2. Operations & Maintenance (O&M) Manuals & Owner Training (CSI 01 78 23 / UFGS 01 78 23)

Under UFGS 01 78 23 Operation and Maintenance Data, submit draft O&M manuals 30 to 60 days prior to Substantial Completion so the Architect and commissioning agent can approve them before Owner facility staff training:

• Mandatory O&M Contents: Indexed by CSI MasterFormat division, including final approved product data and shop drawings, serialized equipment nameplate schedules (model, serial number, voltage, refrigerant charge, belt/filter part numbers), point-to-point control wiring diagrams, preventive maintenance (PM) calendars, lubrication charts, and 24-hour emergency service contacts.
• Owner Demonstration & Training (CSI 01 79 00): Conduct and video-record hands-on training sessions with the Owner’s facility engineers covering HVAC building automation (BAS), fire alarm panel reset, emergency generator transfer, and domestic water booster pumps, obtaining signed attendance rosters.

3. Testing, Adjusting, and Balancing (TAB) & Commissioning (CSI 01 91 13)

Deliver certified third-party NEBB or AABC Testing, Adjusting, and Balancing (TAB) reports confirming that every air diffuser, VAV terminal, exhaust fan, and hydronic coil operates within ±10% of design flow rates with clean MERV 13 filters installed. Pair the TAB report with signed Functional Performance Test (FPT) commissioning scripts, building envelope blower-door/thermography reports, and potable water chlorination/bacteriological clearance certificates.

4. Attic Stock & Spare Parts Turnover (CSI 01 78 46)

Cross-check contract extra-material requirements against the material procurement log template at initial buyout so attic stock is ordered from the exact same production run and dye lot as installed finishes. Box, weather-wrap, label by room/spec section/lot number, stack in the Owner’s designated storage room, and obtain a countersigned Attic Stock Transmittal Receipt for:

• Resilient Flooring, Carpet Tile & Ceramic/Porcelain Tile: 2% to 5% of net installed square footage for each pattern, size, and dye lot, plus matching cove base and grout color cartons.
• Acoustical Ceiling Tiles (ACT): 2% of installed tile count (full unopened cartons) matching edge profile (tegular / square), NRC, and CAC rating.
• Architectural Paint & Coatings: 1 to 2 unopened, custom-tinted 1-gallon cans per interior/exterior paint color, sheen, and primer formula, labeled with manufacturer color code and room schedule.
• Fire Protection (NFPA 13 Spare Sprinkler Cabinet): A dedicated wall-mounted red steel cabinet near the main riser room stocked with spare sprinkler heads of each temperature rating, K-factor, and finish installed:
  • Systems under 300 installed heads: Minimum 6 spare sprinklers
  • Systems with 300 to 1,000 installed heads: Minimum 12 spare sprinklers
  • Systems over 1,000 installed heads: Minimum 24 spare sprinklers
  • Plus at least 1 manufacturer-specific sprinkler wrench for each head model installed.

Equation: Attic Stock Carton & NFPA 13 Spare Inventory Reconciliation

Formula: Required Attic Stock Cartons (N_cartons) = CEILING( (Installed Area A_installed × p_attic) / SF_per_carton )

Worked Example: A project installs 18,400 SF of 24×24 in. modular carpet tile packed at 48 SF per carton with a CSI 01 78 46 specification requiring 3.0% (p_attic = 0.03) attic stock, alongside a wet-pipe fire sprinkler system containing 420 total sprinkler heads (70% concealed pendent 155°F heads and 30% upright 200°F mechanical-room heads):

Calculation:

• Net Attic Stock Carpet Area = 18,400 SF × 0.03 = 552.0 SF
• Required Unopened Carpet Cartons (N_cartons) = CEILING( 552.0 SF / 48 SF/carton ) = CEILING( 11.50 ) = 12 full cartons (576 SF delivered from matching dye lot)
• NFPA 13 Spare Sprinkler Count (300–1,000 head bracket) = 12 spare heads (8 concealed pendent 155°F + 4 upright 200°F + 2 model-specific sprinkler wrenches locked in the riser cabinet)

5. Executed Warranties & AIA Financial Closeout Affidavits (AIA A201 §9.10.2)

Before submitting the Final Application and Certificate for Payment (AIA G702/G703), resolve all open PCOs and change orders to lock the final Contract Sum, and submit the four mandatory contractual instruments under AIA A201-2017 §9.10.2:

Takeaway: Tie final subcontractor retainage release directly to their delivery of approved O&M data (CSI 01 78 23), signed Attic Stock receipts (CSI 01 78 46), red-line as-builts, and unconditional final lien waivers required for AIA G706, G706A, and G707.

Frequently Asked Questions

What are the 3 phases of post construction cleaning under CSI 01 74 23?

Phase 1 (Rough Clean) removes framing and drywall debris, scrapes subfloors, and HEPA-vacuums wall tracks and electrical boxes (29 CFR 1926.1153(f)) before painting and flooring ($0.15–$0.30/SF at 400–650 SF/hr). Phase 2 (Light / Final Detail Clean) peels temporary floor protection and UV tape, washes glazing (GANA 01-0300), details millwork and restrooms with pH-neutral surfactants, and swaps HVAC filters from MERV 8 to clean MERV 13 media 24 to 48 hours before the Architect’s Substantial Completion walkthrough ($0.25–$0.55/SF at 175–300 SF/hr). Phase 3 (Touch-Up / White-Glove Turnover Clean) performs a microfiber HEPA wipe-down of horizontal surfaces after punch-list trades exit and airborne dust settles for 48 to 72 hours ($0.10–$0.22/SF at 500–800 SF/hr).

Why are razor blades prohibited on tempered and Low-E architectural glass during final cleaning?

Under GANA Glass Informational Bulletin 01-0300, heat-strengthened and tempered glass lites frequently carry microscopic fused glass particles (“roller pickup”) transferred from ceramic hearth rollers inside the tempering furnace. Dragging a broad metal razor blade or steel scraper across the glass snaps these fused glass nodes loose and traps construction silica grit beneath the blade, carving permanent comet-tail scratches across the lite and voiding the manufacturer warranty. Approved cleaning requires flooding the lite with water first and lifting soaked point deposits individually with a soft nylon or plastic blade.

What is the difference between Substantial Completion (AIA G704) and Final Completion (AIA A201 §9.10)?

Substantial Completion (AIA A201-2017 §9.8, certified on AIA Document G704-2017) occurs when the Work is sufficiently complete in accordance with the Contract Documents so the Owner can occupy or utilize the space for its intended purpose, backed by an AHJ Temporary or Final Certificate of Occupancy (IBC Section 111). It stops liquidated damages, transfers utilities, security, and insurance to the Owner, starts 1-year §12.2.2 correction warranties, and releases retainage minus a 150% to 200% monetized punch-list holdback. Final Completion (§9.10) occurs only after 100% of punch-list items are signed off, Phase 3 cleaning is complete, O&M manuals, as-builts, and attic stock are accepted, and AIA G706, G706A, and G707 affidavits are delivered.

When should temporary blue/green UV tape and floor protection board be removed?

Peel temporary floor protection (Ram Board, adhesive carpet film) and UV masking tapes during Phase 2 Final Clean before their rated UV and heat dwell-time expires (typically 14 to 60 days). Leaving acrylic masking tape exposed to solar heat beyond its rating cross-links the adhesive polymer onto anodized aluminum mullions and factory finishes, while leaving non-breathable plastic film over curing concrete or natural stone traps moisture vapor and causes efflorescence or wood floor cupping.

What lighting conditions govern drywall and paint punch list inspections?

Under ASTM C840 and Gypsum Association GA-214 (as well as PDCA Standard P1), finished gypsum board (Level 4 and Level 5) and painted wall or ceiling surfaces must be inspected under normal occupancy design lighting from a perpendicular viewing distance of 5 feet (1.5 meters). Shining a handheld LED or halogen work light obliquely flush against the wall surface (“raking light”) violates ASTM C840 inspection rules.
