D3080 COMMISSIONING

Dam Neck Building 530 1862885 Repair Building

- Natatorium Commissioning Statement of Work

SECTION 1: PROJECT OVERVIEW & GENERAL PROVISIONS

1.1 Purpose and Objective

The purpose of this Statement of Work (SOW) is to define the commissioning (Cx) and Testing, Adjusting, and Balancing (TAB) requirements for the Natatorium HVAC Renovation project. Bidding contractors shall include all labor, materials, equipment, and services necessary to fully support and execute the commissioning activities detailed herein.

1.2 Project Context & Boundaries

The renovation includes the mechanical, exhaust, heating, control, fire protection, and lighting systems serving the natatorium. The pool structure, building envelope (except as specified for roofing), and specific water systems remain unchanged.

Systems Being Replaced/Added (In-Scope for Cx):

• Pool Dehumidification System (PDS)

• Source Capture Exhaust System (SCES)

• Space Heating Hot Water System (boilers, pumps, valves, and piping)

• Direct Digital Control (DDC) System

• Fabric Supply Duct System

• Return Air System (All new return air ductwork and grilles)

• Fire Alarm and Detection System (Voice-evacuation, mass notification integration)

• Pool Area LED Lighting and Control System

• Roofing System (with Registered Roof Consultant oversight)

Existing Systems Remaining (Out-of-Scope / Baseline Only):

• Pool Water Heating System

• Domestic Hot Water System

• Pool Water Treatment and Filtration System

SECTION 2: PRE-CONSTRUCTION & PRE-TAB BASELINE

VERIFICATION

Because multiple critical systems and structural boundaries are existing to remain, the Contractor shall perform a rigorous pre-construction assessment and baseline verification prior to any demolition or installation of new equipment.

2.1 Geotechnical and Structural Verification

• Requirement: The Contractor’s geotechnical engineer shall verify that the existing concrete slab and subgrade can support the new, heavier pool dehumidifier unit.

• Commissioning Verification: Prior to approval for startup and functional performance testing, the

Commissioning Authority (CxA) must verify and document that this geotechnical report has been completed and that its physical structural recommendations are successfully implemented.

2.2 Roof Curbs & Penetration Coordination

• Requirement: The project incorporates a new roof installation, governed by a Registered Roof

Consultant (RRC).

• Commissioning Verification: The commissioning process shall verify that the RRC has formally approved the design and that the quality control program is strictly adhered to during construction.

Additionally, the CxA must perform a coordinated inspection of all rooftop HVAC interfaces, verifying that all roof curbs, ductwork penetrations, and equipment supports for the PDS and exhaust fans are installed according to the approved design so that the 10-year roof warranty is not voided.

2.3 Baseline Building Pressure Testing

• Requirement: Measure and document the existing static pressure relationship between the natatorium space, adjacent indoor spaces (e.g., locker rooms, corridors, offices), and the outdoors.

• Objective: Establish a precise pressure baseline to ensure that the new PDS and Source Capture

Exhaust systems maintain a continuous negative pressure environment (0.05 to 0.15 inches w.g.)

under all operating modes, preventing chloramine-laden air from migrating into adjacent spaces.

2.4 Envelope & Structural Inspection

• Requirement: Conduct a sensory and structural inspection of existing exterior window glazing, structural steel, and roof decks to document existing moisture or condensation damage. This serves as a baseline to protect all parties from disputes regarding preexisting conditions versus new system performance.

2.5 Pool Water Temperature Baseline

• Requirement: Measure and record the operating temperature of the existing pool water system over a 48-hour cycle.

• Frequency of Recording: Temperatures must be recorded automatically at 15-minute intervals throughout the 48-hour cycle to capture high-resolution diurnal and operational thermal shifts.

• Rationale: The new DDC system must be programmed with an understanding of this baseline, as the natatorium air temperature must be maintained at approximately 2°F above pool water temperature to control evaporation.

SECTION 3: TESTING, ADJUSTING, AND BALANCING (TAB)

REQUIREMENTS

The TAB Contractor shall be certified by NEBB or AABC and shall coordinate all activities with the Commissioning Authority (CxA).

3.1 Fabric Duct System Calibration

• Static Pressure Verification: Fabric supply air ducts require specific static pressure to inflate properly and distribute air evenly without flapping or sagging. TAB must calibrate the PDS supply fan speed to meet the exact static pressure requirements specified by the fabric duct manufacturer.

• Velocity Profile & Window “Wash”: Verify that the discharge velocities through the fabric orifices achieve the design “throw” to wash exterior glass and cold surfaces, thereby eliminating condensation risk without creating draft conditions at the pool deck level.

3.2 Source Capture Exhaust System Balancing

• Intake Velocity: Calibrate the source capture exhaust intakes to ensure designated airflow rates are achieved directly above the water surface to capture chloramines and heavy gases.

• Draft Prevention: Confirm that air velocities at the pool water surface and adjacent wet deck areas do not exceed 30 feet per minute (FPM) to avoid evaporative cooling and discomfort for swimmers.

3.3 Overall Space Pressurization

• Volumetric Balance: Balance the total supply air, outside air, PDS exhaust air, and Source Capture

Exhaust air volumes to maintain a continuous negative pressure between 0.05 and 0.15 inches w.g.

relative to adjacent spaces across all operational modes.

3.4 Acoustic Performance & MNS Intelligibility Verification

• Requirement: During the TAB phase, the CxA shall require sound level readings (Noise Criteria or NC levels) in the pool area with the PDS and exhaust fans running at maximum capacity.

• Objective: Ensure that background noise generated by the new HVAC system does not exceed levels that would prevent the Mass Notification System (MNS) from passing its required voice intelligibility testing, safeguarding clear communication of emergency broadcasts to building occupants.

SECTION 4: FUNCTIONAL PERFORMANCE & INTEGRATED

SYSTEMS TESTING (FPT)

The Contractor shall assist the Commissioning Authority in executing functional performance testing for all new equipment. Testing shall verify the dynamic response of the systems under simulated load conditions, emergency operations, and sequence transitions.

System / Test Area Functional Testing & Verification Requirements

Pool Dehumidification System (PDS)

Test transitions (Occupied, Unoccupied, Economizer, Purge), compressor & hot gas reheat staging, and relative humidity control (50–60% RH).

Test and verify base-wide communication of all alarm, supervisory, and trouble signals to the base fire alarm receiving station via the radio transceiver.

Lighting System Commissioning

Functionally test the new LED lighting control system to ensure it operates as designed (e.g., scheduling, dimming, occupancy sensing). Measure and verify actual light levels throughout the pool area after

System / Test Area Functional Testing & Verification Requirements installation to confirm compliance with design specifications.

Fire Alarm & HVAC Interlocks

Perform physical simulations of fire alarm events (e.g., triggering a smoke detector or manual pull station) to verify that the DDC system interfaces correctly with the fire panel. Confirm automatic HVAC shutdown sequences (PDS and SCES fan shutdown, damper closures to prevent smoke migration) and verify that systems do not automatically restart until the fire panel is reset.

Mass Notification System (MNS) & PA Integration

Verification that the fire alarm system correctly integrates with and can be overridden by the building‘s MNS. Test LED text signs and the modified PA system’s ability to broadcast emergency messages.

Verify functional connection of new wall-mounted speakers with existing building PA and two-way communication systems.

SECTION 5: OPERATIONS, TRAINING, AND DOCUMENTATION

5.1 Documentation, Warranties, and O&M Submittals

Anticipate minor variations in subsurface conditions between borings. The Contractor is responsible for costs associated with the site preparation, ground improvement and foundations except as allowed by Contract Clause Federal Acquisition Regulation (FAR) 52.236-2, "Differing Site Conditions". The Contractor's Geotechnical Engineer must perform subsurface investigation / testing as required to adequately determine geotechnical factors including the type and capacity of the pipe bedding material. The Contractor's Geotechnical Engineer is required to evaluate the information obtained and prepare a report as described in other portions of this RFP. The minimum requirements for the subsurface investigation and report are as required by FC 1-300- 09N with associated references.

Perform the soils investigation at the site for use in the design and construction of the new facilities. Perform, at Contractor's expense, subsurface exploration, investigation, testing, and analysis for the design and construction of features such as the pavement section(s) and utility structure foundations. Prepare a report including laboratory analysis of samples and recommendations for foundation and pavement design by a Professional Engineer as specified and in accordance with UFC 3-201-01, Civil Engineering.

As a minimum, the successful bidder's Geotechnical Engineer must perform additional subsurface exploration and supplementary laboratory testing as necessary to support the design concept.

Observed site conditions which may present a challenge during design/construction include - The soils that will be exposed after completion of stripping will be soft and at or near the groundwater elevation. Anticipate these marginal subgrade support conditions and incorporate measures into the design and construction procedures to obtain required soil support while maintaining progress for completion on schedule.

Provide personnel under the supervision of a registered Professional Engineer to inspect excavations and soil/groundwater conditions throughout construction. The Engineer is required to perform pre-construction and periodic site visits throughout construction to assess site conditions. The Engineer, with the concurrence of the Contractor and the Contracting Officer, is required to update the excavation, sheeting, shoring and dewatering plans as construction progresses to reflect actual site conditions and is required to submit the updated plan and a written report (with professional stamp) at least monthly informing the Contractor and Contracting Officer of the status of the plan and an accounting of Contractor adherence to the plan;

specifically addressing any present or potential problems. The Engineer must be available to meet with the Contracting Officer at any time throughout the Contract duration. Provide the services of the Engineer at no additional cost to the Government. It is important to note that the presence of loose or compressible soils may result in excessive settlement that could impact the performance of surface bearing structures and supporting facilities such as pavements and utilities. The magnitude and duration of consolidation settlement will be dependent on the composition, depth, and thickness of the compressible soils as well as the successful bidder's design concept. The Contractor's Geotechnical Engineer is responsible for evaluating potential global settlement due to designed grade increases and final structural loads. The Contractor's Geotechnical Engineer must develop any settlement mitigation procedures (such as preloading, surcharging, fill monitoring programs, and ground improvement systems) needed to maintain global settlements within tolerable limits.
