SECTION 01 11 00 - SUMMARY OF WORK

PART 1-GENERAL

1.1 SCOPE OF WORK: These Contract Documents cover the requirements of the Federal Aviation Administration (FAA), Eastern Service Area (ESA) hereinafter referred to as the Government, for the work associated with the Air Traffic Control Tower (ATCT) Project, located at Richmond International Airport 5701 Gulfstream Rd, Richmond VA.

The work is at a critical facility that must remain operational 24 hours a day 7 days a week.

The Contractor must not interfere with or disrupt air traffic operations. The work shall not discharge static electricity, damage, or interfere with other equipment at the facility, and shall not compromise security.

1.2 SUMMARY OF WORK: The work includes the removal of the two natural gas fired boilers and associated hot water pumps in room 118 of the base building at the ATCT and replacing them with new boilers and pumps. The work will include all connectors, valves, and gauges to connect the boilers and pumps to the existing hot water supply and return piping. New boilers and pumps will be installed on existing maintenance pads in the same location as the existing equipment.

The existing maintenance pads can be modified to accept the new equipment. The new boilers will be connected to the existing DC system at the existing DDC panel using the same control points as the existing equipment.

This summary does not cover all aspects of the work. See other specification sections and the drawings for more detailed information.

1.3 INTENT OF CONTRACT DOCUMENTS

A. These Contract Documents (specifications and drawings) indicate the work to be performed for the project. All material, labor, equipment, tools, layout, and supervision must be furnished by the Contractor to complete the work and provide complete operating systems. The Contractor is responsible for the supervision, health and safety, inspection, and quality control of its own work, workers, work areas, and lower tiered subcontractors. Work shall be performed to ICC, NFPA, and FAA codes and standards, and manufacturers' recommendations. All work performed and all materials and equipment used will be subject to approval by the Contracting Officer. This must include, but not be limited to, construction, testing, inspection, scheduling, reporting, and submittals.

B. Titles: Titles to divisions and sections of the specifications and notes and titles on drawings referring to subcontractors, division of work by trade, or type of work are used for convenience and do not imply any separate contractual arrangements of work assignments. Such separations into titles, divisions, sections, or notes should not be construed to establish limits between the Contractor and its subcontractors.

C. Reference to known standards within the Contract Documents means the latest edition in effect on the date of solicitation, unless specified otherwise.

D. Where Contract Documents refer to "Related Work in Other Sections" or "Related Requirements", the Contractor should not consider the list of specification divisions/sections to be all-inclusive. These lists are provided as a convenience for cross-reference and coordination.

E. Order of Preference: Generally, the written word takes precedence over the drawings. Figures marked on drawings should be followed in preference to scale measurements. Large scale

SUMMARY OF WORK 01 11 00 - 2

drawings should govern small scale drawings. The Contractor should not use dimensions scaled from the drawings. All dimensions shown on the drawings must be verified by the Contractor by actual measurements in the field. Any discrepancy between the drawings and specifications and the existing conditions must be referred to the Contracting Officer for resolution before any work affected is performed. The Contractor must compare all drawings and verify the figures before laying out the work and will be responsible for any errors which might have avoided thereby.

1.4 CONTRACT DOCUMENTS

A. Specification and Drawing Review: The Contractor is responsible for complete knowledge and understanding of the Contract Documents throughout the life of the Contract. The Contractor must check the Contract Documents immediately upon their receipt and promptly notify the Contracting Officer of any discrepancies.

B. Contracting Officer: The Contracting Officer (CO) is the person designated to act on behalf of the Government in the performance of this contract. The Contracting Officer's Representative (COR) is the Contracting Officer's authorized representative. The COR is the point of contact for all work on site between the Contractor and Government. The Contractor will coordinate all work through the COR, or will keep the COR informed when dealing directly with the Contracting Officer, and the Government will coordinate through the COR to the Contractor, except in case of urgency or emergency.

1.5 MEASUREMENT AND PAYMENT

A. The contract price constitutes full compensation for furnishing all plant, labor, materials, appurtenances, and incidentals, and performing all operations necessary to construct and complete the items in accordance with these Contract Documents performed by the Contractor.

Payment for each item will be considered as full compensation, notwithstanding that all features may not be mentioned herein. No separate payment will be made for the work, services, or operations required by the Contractor, as specified in Division 1 General Requirements, to complete the project in accordance with these specifications; all costs thereof will be considered as incidental to the work.

1.6 CORRESPONDENCE: All correspondence must be addressed and delivered electronically to the Contracting Officer and the COR, and must be serially numbered commencing with number one (1), with no numbers missing or duplicated. All files/documents must be legible. Enclosures attached or transmitted with the correspondence must also be furnished electronically with copy to the COR. Each serial correspondence must include the contract number and project name and must have only one subject. The Contractor must create and maintain a serial letter log that shows the serial letter number, date, topic, and disposition if applicable.
