SECTION 01110

PROJECT PHASING

PART 1 – GENERAL

1.1 SUMMARY

A. The intent of this Section is to identify major project sequencing requirements and inform the Contractor of Government’s known restrictions that will affect the timing of work and provide general phasing guidelines.

B. The phasing scope described in this Section shall not be deemed to constitute the comprehensive scope of all Contract requirements but is identified herein to assist the

Contractor in the understanding of existing systems and conditions which may affect the

Contractor’s planned work sequence.

C. The Contractor shall provide necessary resources as needed to perform required services including, but not limited to, those described in the RFP, the construction documents, exhibits, and attachments made a part of the contract to successfully complete the construction work required for Back on Campus Phase 02.

D. The ultimate responsibility of comprehensive project phasing rests with the Contractor. All

Contractor phasing plans must be documented in a submittal and reviewed and approved by the Government prior to commencing with such plan. Also phasing activities shall be reflected in the Contractor’s baseline schedule (Project Schedule) and monthly updated

CPM construction schedules. Refer to Section 013110 – Critical Path Method Scheduling for submission of Contractor’s Preliminary, Baseline and updated CPM Project Schedules.

1.2 PHASING AROUND CMS OCCUPANCY

A. The project comprises three distinct portions of work, each with unique occupancy requirements which will influence how construction is sequenced and phased. One construction Notice to Proceed (NTP) date is anticipated on or about November 15, 2022 for all three portions. See also section 011000 for milestone dates for design and construction. However, there may be opportunities for early work packages which could necessitate more than one construction NTP.

1. C2: Upon NTP, C2 will have existing furniture and fixtures that remain and will be part of the GC demolition scope. There are two restrooms serving the C2 spaces. When contractor sequencing and phasing require, both restrooms will be allowed to be closed for a defined period. The defined period will require work plans, review and approval by GSA Building Management.

a. Noisy producing work that may disrupt tenant operations in adjacent spaces must be performed during off-hours or weekend schedules. Noise levels exceeding

65db or noise levels that are consistent will be considered disrupting tenant functions.

2. SLL: The Badging Office currently occupying space on SLL is required to be functional all times during construction, therefore, sequencing for SLL will require in depth analysis with CMS and GC. As such, life safety and building systems serving the occupied spaces as well as egress pathways must be maintained. Upon NTP, SLL will have existing furniture and fixtures that remain and will be part of the GC demolition scope. There are two restrooms serving the SLL spaces. When contractor sequencing and phasing require, both restrooms will be allowed to be closed for a defined period. The defined period will require work plans, review and approval by

GSA Building Management.

a. Noisy producing work that may disrupt tenant operations in adjacent spaces must be performed during off-hours or weekend schedules. Noise levels exceeding

65db or noise levels that are consistent will be considered disrupting tenant functions.

3. CLL: Upon NTP, CLL will have existing furniture and fixtures that remain and will be part of the GC demolition scope.

a. Noisy producing work that may disrupt tenant operations in adjacent spaces must be performed during off-hours or weekend schedules. Noise levels exceeding

65db or noise levels that are consistent will be considered disrupting tenant functions.

b. Removal of trash activities on the Lower Level of the Central building (CLL) shall be performed during off-hours

4. C1: Upon NTP, the first level of the Central building (C1) space will have existing furniture and fixtures that remain and will be part of the GC demolition scope. The contractor will require to coordinate with CMS and to provide the access to the auditorium.

65db or noise levels that are consistent will be considered disrupting tenant functions.

b. Removal of trash activities on the Lower Level of the Central building (C1) shall be performed during off-hours

1.3 BUILDING SYSTEMS INTERFACE

A. Contract work that ties into and/or requires cutting & capping of the operational building systems must be coordinated so that required systems remain fully functional for the duration of this project. Coordination with the CMa and GSA Building Management staff is required to ensure operations are not impacted during project installations and testing.

Following is a brief summary of systems which may require contractor awareness and consideration as system tie-ins or cut/cap activities are conducted.

B. Sprinkler: The building has a full sprinkler system consisting of vertical sprinkler mains, combined risers and sprinkler floor control valve assemblies which are located in the

05/10/2022 egress stairways. GSA Building Management will work directly with Construction

Manager and the Contractor to coordinate all outage requests in advance with GSA Fire

Shop. This also includes daily burning permits which will require coordination between

GC, CMa and GSA Building Management and call made daily to GSA Fire Shop and CMS

Security. See also section 013100 for requirements and processes for utility service interruptions or outages necessary to complete the project.

C. Existing addressable Fire Alarm: The GC is responsible for a fully operational fire alarm system throughout the renovations. The existing FACP and related systems are to remain in service throughout demolition and renovation phases; there will be de commissioning of many existing fire alarm points, re programming and re testing by AHJ. These efforts are the responsibility of the GC. GC to survey and verify requirements of existing fire alarm cable and termination panels.

D. Existing IT/AV/PA/Security cabling: Cabling for security, infrastructure technology, Public

Address System, and Audio Visual services may run through the renovation areas but be connected to other occupied spaces. The GC is to identify, protect and relocate prior to demolishing these existing systems.
