A BSC agreed to provide "construction clean" for a 28,000 RSF tenant improvement buildout in a Class A tower in Philadelphia. The contract said "construction clean per industry standard" at a lump sum of $4,800. When the project concluded, the BSC discovered that the tenant's interior designer expected a three-phase service: a rough-in clean during framing and MEP work, a final clean after drywall and finish installation, and a pre-occupancy detail including window wash, floor protection removal, millwork polish, and HVAC register cleaning. Three separate mobilizations, approximately 180 labor hours total. The $4,800 was priced for the pre-occupancy detail alone. The BSC completed the work to avoid a project dispute, absorbing an estimated $8,200 in under-priced labor.
Tenant improvement cleaning is a distinct service category from ongoing building maintenance cleaning. It requires separate pricing, a separate scope of work, and a separate scheduling protocol that coordinates with the general contractor's construction timeline. BSCs who treat TI cleaning as an add-on to the maintenance contract consistently underprice and over-deliver.
The Three-Phase Construction Clean Model
A standard commercial office TI clean for a mid-size buildout (10,000 to 50,000 RSF) proceeds in three distinct phases, each with a different scope, different labor type, and different scheduling trigger.
- Rough clean (during construction). Performed after framing, rough MEP, and insulation are complete but before drywall is hung. Removes construction debris, scrap lumber, wire offcuts, and insulation fragments from the floor and work area. Protects the base building from embedded construction dust that would later require specialist removal. Rough clean is often scheduled on a weekly basis during active construction. Scope: debris removal to dumpster, floor sweep, air register protection check, and stairwell debris removal if the construction zone is elevated.
- Final construction clean (post-GC substantial completion). Performed after drywall, paint, millwork, and flooring are complete and the GC has signed off on substantial completion. This is the most labor-intensive phase: removes all visible construction dust from all surfaces (sills, horizontal surfaces, above-ceiling accessible areas), cleans floor protection material, vacuums HVAC registers of construction dust, cleans inside millwork and cabinetry, wipes all painted surfaces for paint overspray, and removes window film and protective coverings.
- Pre-occupancy detail (24-48 hours before tenant move-in). The polish phase: spotless glass on all interior partitions and windows, final floor prep (carpet vacuum or hard floor scrub, depending on type), appliance interiors (refrigerator, microwave, dishwasher), restroom fixture detail, and a full walkthrough with the tenant's project manager. This phase should be priced and scheduled as a same-week service, not weeks before occupancy.
Labor Requirements and Crew Type
Construction cleaning at the final and pre-occupancy phases requires different skill sets than routine maintenance cleaning. Final construction clean crews need comfort with HEPA vacuuming of above-ceiling accessible spaces, ladder work for high surface cleaning, and experience recognizing the difference between construction residue and finish damage on new surfaces. A maintenance cleaning crew assigned to a TI final clean without training in construction clean protocols will damage new finishes and miss embedded dust in ways that result in tenant complaints on day one.
| Phase | Labor Type | Approx. Hours per 10,000 RSF |
|---|---|---|
| Rough clean (weekly during construction) | General labor; construction debris experience | 6-10 hrs per visit |
| Final construction clean | Trained construction clean crew; HEPA vacuum certified | 40-60 hrs total |
| Pre-occupancy detail | Detail-trained crew; glass cleaning certified | 15-25 hrs total |
HEPA vacuuming of above-ceiling construction dust is required in buildings where the HVAC system serves both the TI zone and adjacent occupied tenants. Construction drywall dust that is not removed before the HVAC system is restarted will circulate into occupied zones and generate IAQ complaints from tenants who were not party to the construction activity. The OSHA construction silica page covers respiratory protection requirements for TI cleaning crews working in post-drywall dust environments.
Pricing TI Cleaning Correctly
TI cleaning is priced per square foot of buildout area, not per RSF of total building. The three phases priced separately and billed on completion milestones is the correct structure. Typical market pricing (2024-2025, major metros): rough clean $0.08 to $0.14 per buildout SF per visit; final construction clean $0.50 to $0.90 per buildout SF; pre-occupancy detail $0.30 to $0.55 per buildout SF. Total three-phase cost for a 30,000 SF buildout with four rough clean visits runs approximately $24,000 to $38,000 in a major metro market.
The most common pricing error is not separating the phases. A single lump-sum "construction clean" bid that the GC interprets as covering all three phases and the BSC interprets as covering only the pre-occupancy detail creates the dispute described above. Write the phases, the triggers, and the deliverables explicitly in the scope of work. The Opora Scope of Work Generator includes a TI cleaning module with phase-specific deliverables and billing trigger language.
Tradeoff: TI Clean and Base Building Restoration
TI construction inevitably impacts the base building beyond the buildout zone: construction dust in elevator cabs used to move materials, lobby floor traffic from workers and materials, stairwell debris from vertical transport. The base building cleaning contract almost never covers TI-generated soil in common areas; that is an additional charge to the GC or tenant. If the base building cleaning contract runs at a flat monthly rate while a TI project is active, the BSC is absorbing the incremental cleaning cost of the construction activity without compensation.
The correct contract structure: a change order to the base building maintenance contract covering TI-period common area incremental cleaning, billed to the GC or property manager on a time-and-materials basis, with a floor-by-floor access log to document when construction crews used building common areas. That documentation supports the billing and is available if the GC disputes the charge.
For the adjacent IAQ compliance dimension of TI cleaning, the office IAQ and ASHRAE guide covers post-construction ventilation requirements before occupancy. The office floor care guide covers the floor prep phase specific to different surface types installed during TI. The office cleaning hub indexes all related tools. The IAQ glossary entry covers terms relevant to post-construction air quality. The EPA Indoor Air Quality Building Action Plan guidance addresses post-construction IAQ management. The CDC NIOSH indoor environment quality page covers construction dust and IAQ research relevant to pre-occupancy cleaning design. The BLS OEWS SOC 37-2011 wage data applies to TI crew labor cost modeling.
The ISSA CIMS standard documentation framework applies to pre-occupancy projects: scope-of-work records, inspection logs, and chemical usage tracking are all part of the quality evidence package a property manager expects at project close.
