1. INTRODUCTION

1.1. Tunnel 9 legacy buildings’ design uses a central system of chilled water (CW), hot water (HW), and steam to heat and cool buildings. Boilers that were intended to operate year round now only operate from May to October. With no heat energy, some controls that look for humidity inputs to remove moisture result in excessive cooling. Many instruments and certain equipment have been disconnected from pneumatic control systems. In addition, over decades, rooms were isolated from the central system and units were installed to provide specific-room climate control. In noting these deficiencies, it is observed that GSA’s maintenance contractor spends approximately a third of their time manually intervening to correct temperature swings in various occupied parts of buildings.

1.2. Multiple solutions are needed to solve problems in different areas. A system wide BMS that was formerly proposed is not appropriate as there are too many disparate variables to place entire buildings under one HVAC solution. Any solution and selection of controllers/software should emphasize task simplicity and be easily user addressable. Human-machine interface (HMI), or laptop, is desired outside secure areas, as maintenance staff lack unescorted access to many areas.

1.3. The scope of work (SOW) presented herein identifies a solution for temperature and humidity problems for two mission critical secure spaces in Building 405.

The SOW introduces automated controls for Mechanical Room 1208 to replace original pneumatic components, along with selected equipment to be installed inside ductwork. Both rooms serve critical testing activities:

SUBMITTAL PROCEDURE

PART 1 GENERAL

1.1 DESCRIPTION OF REQUIREMENTS. This section specifies procedural requirements for non-administrative submittals, including but not limited to shop drawings, product data, manufacturer’s certificate, design data, calculations, and verifications, manufacturer’s instructions, manufacturer’s field service reports, samples, operation and maintenance manuals, and other miscellaneous work-related submittals. These submittals are required to amplify, expand, and coordinate other information contained in the contract.

Non-work-related submittals are addressed elsewhere in the contract rather than in the specification and may include items such as: contract progress schedule, permits, payment applications, performance and payment bonds, insurance certificates, and progress reports.

The Contracting Officer may request submittals in addition to those specified when deemed necessary to adequately describe the work covered in the respective sections of the specification or statement of work.

1.2 SUBMITTAL PROCEDURE

A. Definition: For the purposes of this section, the term “Contractor” denotes the prime contractor.

B. Listing: The statement of work contains a summarized listing of item submittals requiring approval for the work. The listing is included for the convenience of users of the contract documents. The listing may not be all inclusive and additional item submittals may be required.

C. Risk: Do not proceed with the part of the work covered by an item submittal including purchasing, fabricating, and delivering until approval is received.

Machinery, equipment, material, and articles that do not have the required approval shall be installed or used at the risk of subsequent rejection. Any fabrication or other work performed in advance of the receipt of accepted item submittals and approvals shall be entirely at the Contractor’s risk and expense.

D. Transmittal Timing: Coordinate the preparation and processing of item submittals with the performance of the work. Prepare and transmit each item submittal to the Contracting Officer sufficiently in advance of the performance of related work and other applicable activities. Transmit related item submittals for the same unit of work so that processing will not be delayed by the Government's need to review submittals concurrently for coordination. No delay damages or time extensions will be allowed for time lost in late submittals.

Appendix A-2

E. Content: Each submittal shall be complete and in sufficient detail to allow ready determination of compliance with contract requirements. Complete AF Form 3000 and attach as cover sheet for each submittal. Contractor may include multiple item numbers on an AF Form 3000.

F. Language: All item submittals shall be written in English, including documents, notes on drawings, sketches, and/or samples, calculations, manuals, and all other instances of written text and communication.

G. Units: All item submittals shall be marked or show dimensions and values in the same units as specified in the contract documents.

H. Review Time: Allow sufficient time so that contract performance will not be delayed as a result of the time required to properly process submittals, including time for re-submittals, if necessary. Allow 10 working days for initial Government processing of each submittal. No extension of time will be authorized because of the Contractor's failure to transmit submittals to the Government sufficiently in advance of the work.

I. Contractor Certification: All submittals shall be carefully reviewed by an authorized representative of the Contractor prior to submission to the Government. Each submittal shall be dated, signed, and certified by the Contractor as being correct and in strict conformance with the contract documents. No consideration for review by the Government of any Contractor’s submittal will be made for any items which have not been so certified by the Contractor. All noncertified submittals will be returned to the Contractor without action taken by the Government, and any delays caused thereby shall be the total responsibility of the Contractor.

J. Deviations: Should any item submittals required by the contract documents show deviations from the contract requirement, the Contractor shall make specific mention of such deviations in the letter of transmittal, including stating cost effects, and product and system limitations which may adversely affect the work, in order that if acceptable, suitable action may be taken for proper adjustment of the contract; otherwise the Contractor will not be relieved of the responsibility for executing the work in accordance with the contract documents and the approved submittals. Contractor shall clearly mark the proposed variation in all documentation and specifically point out deviations from contract requirements in transmittal letters. Failure to point out deviations may result in the Government requiring rejection and removal of such work at no additional cost to the Government. Deviations from contract requirements require Government approval and will only be considered when advantageous to the Government. When proposing deviations, deliver written request to the Contracting Officer, with documentation of the nature and features of the deviation and why the deviation is desirable and beneficial to the Government. If lower cost is a benefit, include an estimate of the cost savings. In addition to documentation required for deviation, include the submittal information

Appendix A-3 required for the item. Allow an additional 10 working days beyond normal submittal review period for consideration by the Government of submittals with deviations.

K. Approved Submittals: The part of the work covered by the approved item submittal may proceed provided it complies with the requirements of the contract documents. Final acceptance will depend upon that compliance.

The term “Approved” shall only indicate that there is no exception taken to the submittal. Approval of the item submittal shall not be construed as a complete check, and indicates only that the general method or other information appears to meet the contract requirements. Approval does not relieve the Contractor of the responsibility for any error which may exist.

After item submittals have been approved by the Contracting Officer, no resubmittal for the purpose of substituting materials or equipment, or changes to any other information will be considered unless accompanied by an explanation of why a substitution or change is necessary.

L. Disapproved Submittals: Contractor shall correct disapproved item submittals and resubmit for approval within timeframe noted. If no date is given, Contractor shall submit corrected submittal within 10 working days.

If the Contractor considers any correction or notation on the returned submittal to constitute a change to the contract drawings, specification, or statement of work the Contractor shall notify the Contracting Officer.

M. Responsibility: The Government’s review of Contractor submittals shall not relieve the Contractor of the entire responsibility for the correctness of details and dimensions and conformance to the specifications. The Contractor shall assume all responsibility and risk for any mistakes and/or costs due to any errors in submittals.

N. Inconsistencies: If a conflict or inconsistency arises between an approved item submittal and the contract documents, the contract documents shall govern.
