The General Conditions of the Contract are hereby, except as same may be inconsistent herewith, made a part of this Specification, to the same extent as if herein written in full. Copies of the General Conditions of the Contract are on file and may be referred to at the Office of the Architects. Scope of Work: The work involved and outlined by these Specifications is for the construction work for the completion of the Office Addition for , as further illustrated, indicated, or shown on the accompanying drawings. Examination of Site: Before submitting a proposal for this work, each bidder will be held to have examined the site, satisfied himself fully as to existing conditions under which he will be obligated to operate in performing his part of the work, or which will in any manner affect the work under this contract. He shall include in his proposal any and all sums required to execute his work under existing conditions. No allowance for additional compensation will be subsequently in this connection, in behalf of any contractor, or for any error or negligence on his part.

Section 3 Specifications and Materials X Drawings and Specifications: These Specifications are intended to supplement the Drawings, the two being considered complementary, therefore, it will not be the province of these Specifications to mention any portion of the construction which the drawings are competent to explain and such omission will not relieve the contractor from carrying out such portions as are only indicated on the drawings. Should the items be required by these Specifications which are not indicated on the drawings, they are to be supplied, even if of such nature that they could have been indicated thereon. Any items which may not be indicated on the drawings or mentioned herein, but are necessary to complete the entire work, as shown and intended, shall be implied and must be furnished in place. The decision of the architects as to the proper interpretation of the Drawings and these Specifications shall be final and shall require compliance by the contractor in executing the work. Figured dimensions shall have precedence over scale measurements, and details over smaller scale general drawings. Should any... Principles and Definitions: Where the words "approved," "satisfactory," "equal," "proper," "ordered," "as directed," etc., are used, approval, etc., by architects is understood. It is understood that when the word "Contractor" is used in these Supplementary General Conditions, the work described in the paragraph may apply to all Contractors and Subcontractors involved with the work. Temporary Facilities: Temporary Heat: Each contractor shall provide the necessary temporary heat needed for materials, water, etc., or any other heat required to accomplish his work. If the permanent heating plant is used for temporary heat, the owner will pay for its operation. Temporary Light & Power: The general contractor shall arrange and pay for a temporary electrical service taken from the existing building for use by all trades, include 60 amp, 2 pole, 4 outlet fused panel mounted on pole or wall at the site. The electrical contractor shall provide temporary light within the structure as necessary and directed. General contractor will pay for all temporary electrical service until such time when permanent meter shall be installed. Temporary Sheds for Storage: The general contractor may provide and maintain on the premises, where directed, watertight storage shed, or sheds, for storage of all material which may be damaged by the weather.

Including fly ash in mixes where permitted. Not applicable if a specified amount of fly ash is listed with the mix. The minimum cement requirement may be met by substituting 1.33 lb. of fly ash for each 1.0 lb. of Portland cement replaced, to the maximum allowed ratio of fly ash to cement. The maximum ratio of fly ash to Portland cement shall be limited to 20%. 2. Tolerance on air content shall be as delivered. 103 #57, 1" 3. Normal weight. 4. Steel fibers are required in floor slabs designated "CWT" on Architectural finish schedule. 5. The Architectural concrete mix shall be designed to minimize shrinkage. A retarder shall be used to minimize heat gain and maximize long-term strength gain. A high range water-reducing admixture shall be used to limit the W/C ratio. The retarder may cause a delay in removal of the formwork. Strength development of the concrete may be critical in cycling formwork, depending on form system. General Conditions: The contractor shall read the General Conditions and Supplementary General Conditions which are a part of these Specifications.
