Do not scale drawings. Verify dimensions in field prior to commencement of work. Refer to architectural drawings for all dimensions. 2. All subcontractors shall be licensed, experienced, and thoroughly knowledgeable in their respective areas of the construction industry and shall perform in a responsible manner with established construction sequence, shall recognize the priority of the construction documents, and shall inform the prime contractor of potential problems when the construction documents are unclear or inconsistent. 3. Subcontractors shall be responsible to notify the prime contractor of discrepancies or conflicts in the construction documents found during bidding and/or prior to performing the work. 4. Examination of bidding documents. A. Each bidder shall examine the bidding documents carefully, and not later than seven (7) days prior to the date of receipt of bids, shall make written request to the architect for interpretation or correction of any discrepancies, ambiguities, inconsistencies, or errors therein which he may discover. The architect will issue any interpretation or correction as an addendum. Only a written interpretation or correction by addendum shall be binding. No bidder shall rely upon interpretations or corrections given by any other method. If discrepancies, ambiguities, inconsistencies, or errors are not covered by addendum or written directive, contractor shall include in his bid, labor materials and methods of construction resulting in higher cost. After award of contract, no allowance or extra compensation will be made on behalf of the contractor due to his failure to make the written requests as described above. B. Failure to request clarification during the bid period of any inadequacy, omission, or conflict will not relieve the contractor of his responsibilities. The signing of the contract will be considered as implicitly denoting that the contractor has a thorough comprehension of the full intent and scope of the construction contract drawings and specifications. 5. Provide a base bid which shall include only specified equipment or equipment listed as equivalent. No substitutions for the listed equipment shall be allowed in the base bid. A. The manufacturer of equipment or materials first named on the drawings is the basis of design. Other manufacturers listed are considered general equivalents only. B. Coordination of general equivalents and substitutions: where contract documents permit selection from several general equivalents, or where substitutions are authorized, coordinate clearance and other interface requirements with mechanical and other work. 1) Provide necessary additional items so that selected or substituted item operates equivalent to the basis of design and properly fits in the available space allocated for the basis of design. 2) Provide all features which are standard on the basis of design plus any specified options. 3) Be responsible for assuring that piping, conduit, duct, flue, and other service locations for general equivalents or substitutions do not cause access, service, or operational difficulties any greater that would be encountered with the base design. 6. Inasmuch as design for remodel and/or rehabilitation requires that certain assumptions be made regarding existing conditions, and because some of these assumptions cannot be verified without destroying otherwise adequate or serviceable portions of the building, the Engineer cannot assure the Owner or the contractor that the professional consulting services herein encompass all contingencies. Field coordination during construction is imperative. Make reasonable allowances for unseen conditions. 7. The existing building will be occupied by the Owner during construction. Continued operation of the facility shall not be hindered by this work. Account for all additional costs which may be incurred due to the difficulty of working over and around employees, furniture, equipment, etc.; and due to the hours of the day in which an area may be accessible when compiling this bid. 8. Be responsible to field verify existing equipment or ductwork remaining to be connected to existing systems. Provide ductwork, piping, controls, diffusers, etc., as required to restore continuity of system(s), or to make new work meet existing conditions, whether indicated or not. 9. Subcontractor shall verify existence and location of all utility services and coordinate as required by their respective area of the construction, notifying the prime contractor of variations or conflicts. 10. If not specifically defined in these construction documents, materials and/or equipment shall be identified by the subcontractor with sufficient time to allow selection, purchase, and delivery to maintain construction schedule. 11. Provide mechanical demolition as required. Refer to architectural demolition drawings for location and extent of demolition required. Visit site prior to bid to determine extent of work involved.

All existing support rods and straps now supporting ducts, pipes, air tubing, electrical conduit, etc. that are removed to allow room for installation of new ductwork shall be relocated and reinstalled, or replaced if damaged. 15. Cap all demolished and abandoned duct take-offs at trunk duct. 16. Work shall be performed in a workmanlike manner to the satisfaction of the architect, Owner, and Engineer. 17. It is the contractor's responsibility to perform his/her work in conformance with all applicable codes, ordinances and life safety features as required by local, state, or national authorities. The contractor shall verify with the architect if modification of his/her work is required for compliance. 18. All work of all trades must be in strict compliance, or exceed the minimum material and method requirements of the 2015 version of the International Building, Mechanical, Energy Conservation, and Fire Codes; the 2012 International Plumbing and Fuel Gas codes; and the 2014 National Electrical Code, most current NFPA, all local ordinances and amendments and manufacturer's installation recommendations. If a conflict between those publications exists, the most stringent requirement shall apply. 19. Pay for and secure all required permits and inspections. Prior to final payment, turn over to architect all certificates of completion. 20. Warranty the installation against defects in materials and workmanship. The warranty shall be for a period of one year after Owner's acceptance. Defects shall be promptly remedied without cost to the Owner. 21. Submit record documents to architect. Documents shall include all addendum items, change orders, alterations, reroutings, etc. 22. Systems shall be complete, operable, and ready for continuous operation prior to acceptance by the Owner. 23. Systems shall be tested for proper operation. Perform at a minimum all code required tests or systems. If tests of work are defective, contractor shall make corrections necessary at no additional cost to Owner. 24. All materials and/or equipment shall be handled and installed as per manufacturer's specifications and recommendations. 25. Submit all mechanical division shop drawing and product data at one time. Partial submittals will be rejected. 26. Shop drawing submittals shall state capacities, sizes, etc., of all equipment and devices and shall be certified and include computer based project specific selections where applicable.
