Post-Construction Final Clean for Developers and Owners
Publicly funded affordable housing, multifamily, and commercial builds in Greater Portland carry DMWESB participation goals, BOLI prevailing wage requirements, and owner-specified closeout standards. Strong Tower is a COBID-certified MBE/WBE firm that delivers the final clean scope — and the documentation — your project requires.
Common challenges
- DMWESB participation goals require a certified sub — not all final clean providers qualify
- Affordable housing and public projects require documented Green Seal or equivalent product use
- Multiphase developments need final cleans sequenced across units or floors on a rolling schedule
- Owner-specified closeout standards (e.g., Spec 017700 scope language) must be met precisely
- Subcontractor documentation — COI, certification, prevailing wage compliance — must be in order before award
What we deliver
- COBID 8404 MBE/WBE certification satisfies DMWESB participation requirements
- Green Seal GS-37 compliant products documented for spec compliance
- Full closeout scope: dust-out, detail clean, glass restoration, touch-up
- Rolling schedule for multiphase projects — clean completed units while others finish
- Written scope and COI documentation for subcontract compliance
- Prevailing wage scheduling available for publicly funded projects
Questions
What does the COBID 8404 certification mean for a Portland development project?
COBID 8404 is Strong Tower's Oregon DMWESB certification number. It certifies us as a Minority Business Enterprise (MBE) and Woman Business Enterprise (WBE). On publicly funded Portland projects that carry DMWESB participation goals, engaging Strong Tower as a subcontractor helps satisfy those requirements.
Do you use products that meet Green Seal or GS-37 requirements?
Yes. We use Green Seal GS-37 compliant cleaning products on all jobs. We can provide product documentation for projects that require it, including LEED or healthy building certifications.
Can you handle rolling final cleans on a multiphase development?
Yes. We work with developers and GCs on phased closeout schedules — cleaning completed units or floors while other phases are still finishing. This is common on multifamily affordable housing projects in Greater Portland.
What does Spec 017700 closeout cleaning scope require?
Spec 017700 (Closeout Procedures) typically requires cleaning each surface to the condition expected in an average commercial building maintenance program, and restoring glass and mirrors to their original condition. Strong Tower's final clean scope meets this standard.
Are you available for publicly funded Portland projects with prevailing wage requirements?
Yes. We work on publicly funded projects and are familiar with BOLI prevailing wage schedules for Oregon. Contact us early in the bid process so we can factor the right rates into the scope.
