There will be tempering heaters placed as closely as possible to the cold air intake, and there will be reheaters placed at the bases of the various flues which lead to the rooms, the whole arrangement being such that when the fans are stopped, the whole building will still be warmed to some extent by gravity. Direct radiators will be placed in offices, toilets, corridors and similar rooms, The machinery, except the Auditorium supply fan and exhaust fans, will be steam operated, so that the building may be independent of electric supply for heating, while the exhaust fans will be electrically operated so as to give ventilation when the heating plant is not needed. The work- ing pressure on the boilers will be not to exceed 35 pounds. GENERAL CONDITIONS The general conditions of the architect’s specifi- cations, giving instructions and information relating to requirements, time of completion, alterations, per- mits, contract and bond, payments, drawings, etc., are hereby made a part of this specification, and contractors are required to acquaint themselves with ‘these general conditions, which will be made a part of the contract. Where no special quality of material or labor is mentioned, it 1s understood that the quality of materials and labor shall correspond with that called 131 Specifications for Labor and Material for in the architect’s specifications for similar work. WORK INCLUDED All instructions in these specifications such as “‘do,” “provide,” “furnish,” “build” and the like shall be read and understood as directions given to the con- tractor. All labor and material necessary for the completion and installation of the heating and ven- tilating system is included. WORK NOT INCLUDED: Other contractors will: Leave tees in the pump room near the receiving tank for hot and cold water connections, which will be continued from this point by the contractor.

LIABILITY INSURANCE The contractor shall carry approved insurance pro- tecting himself as well as the owner against damage caused by accident in or to the building, and against lability for injury to persons during construction and until the final acceptance of the work. GUARANTEE The contractor shall make good the following re- quirements: All apparatus shall be free from defects of material or workmanship. All apparatus shall be so built and installed as to deliver its full rated capacity at the highest effi- ciency for which it was designed. Steam and condensation shall circulate throughout the apparatus without objectionable noise at not over one pound pressure at the reducing valve, and all parts of the heating surface, blast and direct, shall be heated under this condition. Fresh air shall be delivered at the inlets to the rooms simultane- ously, in amount equal to or in excess of the volume called for in the schedule. Air shall be exhausted by the mechanical exhaust system, at the outlets from the rooms, in amounts equal to or in excess of the volume called for in the schedule. | The entire mechanical apparatus shall operate at capacity without objectionable noise or vibration. 1 Specifications for Labor and Material TEMPORARY CONNECTIONS The contractor shall set all direct radiators tem- porarily one time as a part of the contract, without extra compensation, when so ordered by the architect. Temporary valves shall be furnished for such tem- porary connections, these valves to remain the property of the Contractor, as the diaphragm valves for permanent use may not be used for temporary setting. TEMPORARY HEATING If the plant shall be used for temporary heating, it will be operated by the contractor, who will be responsible for it during such use. The contractor shall include in his bid the cost of operating the plant for not less than thirty 24-hour days, at the con- tractor’s risk, including all necessary supplies except electricity and fuel. The thirty days’ operation by the contractor will be for temporary heating or for adjusting and running in the machinery, as the owner may dictate. The thirty days need not neces- sarily be consecutive, but may begin as soon as temporary heat is needed and may terminate not later than thirty days after the completion of the building. The contractor shall be responsible for securing a certificate from the heating inspector, in writing, at the beginning and ending of each period of operation, in case, for instance ,the operating period should be interrupted by a break-down or by warm weather. If the owner requires operation by the contractor for a period longer than the thirty days above pro- vided, the contractor shall furnish such operation, still at his own risk, at an agreed price per day. 134 For Harvard School Building SUBSTITUTIONS Certain definite makes of apparatus are specified as a minimum standard.
