Ms. Angel Barnes <br />June 24, 2025 <br />Page 2 of 5 <br />MBP Facility Solutions, LLC <br />2600 Park Tower Drive, Suite 801 | Vienna, Virginia 22180 | 703-641-9088 | www.mbpce.com <br /> <br />SCOPE OF WORK (SOW) <br />MBP-FS’ Subcontractor Phoenix will: <br />1. General Requirements: <br />a. Review and finalize the TAB plan in coordination with the BAS controls contractor. <br />b. Document all measured values and identify any discrepancies, deficiencies, or conditions <br />affecting system performance. <br />c. Provide recommendations and annotated documentation as required. <br />2. Air Handling Units (AHUs): <br />a. Two rooftop air handling units (RTU) will be evaluated. In coordination with the BAS <br />contractor, dampers will be set to fixed positions (noted in the original TAB report) and all <br />VAVs will be commanded to their maximum cooling airflow setpoints. <br />b. Once the fan speed increases to meet the static pressure setpoint, the AHUs will be <br />operated at a fixed speed via VFD manual mode or BAS override. <br />c. Outdoor, return, and exhaust/relief damper positions will be recorded. <br />d. Supply, return, outdoor, and exhaust airflow will be measured and recorded. <br />e. During outdoor airflow measurements, the contractor will record the values reported by the <br />installed airflow measuring device. If the device is found to be out of calibration, <br />adjustments to the correction factor will be made. <br />3. Exhaust Fans: <br />a. Seven exhaust fans will be tested. Airflow at each fan will be measured and recorded. The <br />operational condition of each fan will also be noted. <br />b. Speed settings will be adjusted as required to achieve the design airflow setpoints. <br />4. Constant Volume Air Terminal Unit (CV ATU – Interview Room 6): <br />a. Following installation of new air terminal unit controller by Siemens, the controller will be <br />calibrated, and a correction factor established. Supply and exhaust airflow will be adjusted <br />to achieve negative pressurization in the space. <br />5. Variable Air Volume (VAV) Terminal Unit Sampling: <br />a. Five VAVs associated with each RTU (ten total) will be sampled. Calibration and correction <br />factors will be verified in the BAS to confirm that original TAB settings are accurate. <br />b. Record outlet airflow values for each VAV. <br />6. Building Pressurization Testing: <br />a. Readings will be taken at eleven exterior door locations to confirm positive pressurization of <br />the building envelope. <br />b. Adjustments will be made to the RTUs and exhaust systems to achieve a positive building <br />pressure condition. <br />7. Documentation and Reporting: <br />a. A comprehensive TAB report will be provided, detailing all findings, airflow measurements, <br />and deviations from design. <br />Docusign Envelope ID: D9853A4E-EA2F-4C7B-B381-199608BC7E0E
