Before placement and installation of work subject to tests by testing laboratory, the Contractor shall notify the COR in sufficient time to enable testing laboratory personnel to be present at the site in time for proper taking and testing of specimens and field inspection. Such prior notice shall be not less than three workdays unless otherwise designated by the COR.

D. All employees of general contractor and subcontractors shall comply with VA security management program and obtain permission of the VA police, be identified by project and employer, and restricted from unauthorized access.

E. Hours of Work: The normal working hours of this facility are Monday through Friday 7:00AM to 5:30PM. Work shall be scheduled to be performed during normal operating hours whenever possible, and after hours whenever deemed necessary by the VA Project Engineer (COR) due to operational requirements of the Medical Center. Work conducted in occupied areas, work that will create medical center interruptions, work that will create utility shutdowns/disruptions, work that will create noise & vibrations is designated as after-hours. Any after-hours work shall be scheduled in writing by the Contractor using the facility standard request form. Specific special work hours for individual projects shall be as follows for coordinating shutdowns and after-hours work.

The drawings show or describe the general arrangement of equipment, articles, assemblies, appurtenances but do not show all required fittings, drains, air vents, supports and may not identify all required accessories, components, fittings, and offsets that are necessary to properly complete the installation for the purpose intended. The contract drawings are diagrammatic only intended to show general layout of conduit, ductwork, piping, equipment, terminals, specialties and not intended to show all required offsets, details, accessories and equipment to be connected. Provide all necessary fittings, offsets and pipe runs based on field measurements and reviewed coordination drawings. Coordinate with other trades for space available and relative location of equipment and accessories to be connected at all locations. The

Contractor shall alter locations of items where necessary to avoid interference and clearance difficulties. Locations of components and equipment shall be adjusted to accommodate the work with interferences anticipated and encountered. The Contractor shall determine the exact routing and location of systems prior to fabrication and installation. Accurate field measurements and coordination drawings shall be prepared to establish the locations and characteristics of the various systems (new and existing to remain). It is the intent of the drawings/specifications that the Contractor provides all materials, labor and coordination necessary to complete the work described or implied by the contract documents at no additional cost/time to the

Government. The Contractor shall propose with submitted coordination drawings other dimensions with similar characteristics where necessary to avoid interferences and clearance difficulties. Should the contract documents not agree with themselves the greater quantity of superior work and materials shall be performed.
