Private Office Finishes Analysis

Standard Private Office Finish Package

Based on the third floor finish plan (A2.3.2) and finish schedule (A10.6.1), private offices consistently use the following finish package:

• Flooring: C2 - BENTLEY ALLEGRO carpet
  - Size: 18"x36" tiles
  - Backing: NEXSTEP CUSHION
  - Pattern: TBD (to be coordinated with architect)
  - Finish: PULSE 800243
  - Class B Flame Spread Rating
• Base: RB1 - Rubber base
  - Likely Johnsonite 4" Toeless Base in Black (40)
• Walls: P1 - Paint
  - Kelly Moore KMW46 / Picket Fence (White)
• Ceiling: ACT1 - Acoustic Ceiling Tile type 1

Construction Management Insights

• Material Coordination: The carpet pattern orientation requires coordination with the architect prior to installation. This should be scheduled as a pre-installation meeting to avoid costly rework.
• Fire Rating Compliance: The C2 carpet has a Class B Flame Spread Rating requirement. This is critical for code compliance and should be verified through submittal review before materials are ordered.
• Transition Details: The drawings specify to "feather out levels approximately 5'-0" long to provide smooth transition where floor materials change." This is particularly important where private offices (C2 carpet) meet open office areas (C1 carpet) or circulation spaces (CN2 concrete).
• Mock-Up Requirements: A 10'x10' mock-up installation of floor finishes is required for owner/architect review. This should be scheduled early in the construction process to allow time for adjustments.
• Consistency Across Floors: While the query focuses on the third floor, the finish schedule shows that private offices on Level 1 (rooms 107, 108) use a similar finish package (CPT-1, RB-1, PT-1, ACT-1), suggesting a consistent design approach throughout the building.
• Material Differentiation: Private offices use a different carpet specification (C2) than open offices (C1) and conference rooms (C3/C4/C6). This differentiation should be clearly communicated to installers to prevent mixing of materials.
• Quantity Takeoffs: With numerous private offices using the same finish package, accurate quantity takeoffs are essential. Based on the floor plan, approximately 20+ private offices on the third floor will require the C2 carpet specification.
• Quality Control: The finish schedule notes that carpet installation should "use largest tile size" and "minimize number of seams," indicating a focus on aesthetic quality that should be emphasized during installation supervision.

This consistent finish package across all private offices simplifies material procurement and installation while creating a unified aesthetic throughout the private office spaces.
