Any correspondence outside the platform shall not be the governing authority's responsibility and will be at the contractor s expense. Official project correspondence and collaboration include, but are not limited to: RFIs, submittals, schedules, shutdown requests, actionable tasks, reports, testing, safety inspections, photos, and site surveys. Contractor must inform the COR of any staff changes NLT 2 business days from the change. Staff changes pertain to staff who were granted access to the ACC platform. Contractor shall request termination of access, replacement of personnel, and/or any other action that may affect the contractor's ability to maintain the required utilization of the platform. Justification: The St. Albans Laundry mechanical room contains four Air Handling Units (HV s) and exhaust fans that provide ventilation and environmental control for laundry operations. Three of these units (AHU-1, AHU-3, AHU-4) are non-operational, along with inaccurate functional exhaust fans, resulting in inadequate airflow and compromised environmental conditions. This project seeks to execute immediate corrective repairs to restore serviceability for the overall ventilation system/units as an interim measure until a long-term design & Construction upgrade project is implemented.
