This document, "Attachment 4 - Phasing Plan.pdf", provides a detailed construction phasing plan for the NIST Building 215 Cleanroom Re-Balance project. It supplements the original design documents by outlining a phased approach to minimize disruption to ongoing cleanroom operations, as extended shutdowns are not permissible.

• Phased Approach: The plan details how each cleanroom bay will be isolated and shut down individually to allow other areas to remain operational.
• Scope per Phase: Each phase includes tasks such as testing associated AHUs, performing equipment modifications, providing protective coverings, isolating bays, shutting down AHUs and exhaust tools, replacing HEPA filters and housings, replacing magnehelic gauges and AFMs, rebalancing air systems, and performing HEPA and cleanroom recertification.
• Guidelines and Assumptions: Includes parameters for construction hours, coordination with holidays, use of multiple crews, and the requirement for contractors to verify existing conditions and submit phasing plans for approval.
• Specific Phases: Outlines a sequence of phases including Class 1000 Corridors A and B, Central Corridor, various Cleanroom Modules (A101-A106, B101-B107), Spaces D106-D108, D101-D105, and Non-critical spaces.
• Appendix One: Presents a visual representation of the anticipated construction sequence, estimating approximately 19 construction phases.

This document is crucial for bidders as it defines the methodology for executing the cleanroom re-balancing work. It highlights the need for careful scheduling, coordination with NIST personnel and users, and the requirement to minimize operational impact. Bidders must understand this phasing plan to accurately estimate timelines, resources, and potential disruptions during their proposed work.
