Hunson, Michigan State College architects. Using these plans and specifications, a quantity estimte was first nade, checking frcn time to time with' the contractor of this Job, Reniger Construction Cmpany. From the quantity estimte the estimate of cost of nterials and labor was nade. l'he Bngineeriflews-Reccrd, Vol. 1283 lo. 17: Pages 595-736, April 23, 1942,.was used as reference for mterials prices as of Decuber, 1941, and any reference nde to this ngasine will be indicated by "ERR”. The union wage rates for construction trades were acquired from the Lansing Building and Construction Trade Council, in affiliate of the Building Trades Department of the Anerican.Federation of Labor. Any reference made to CONSTRUCTION ESTIMATES AND COSTS by n. s. Pulver, 3.3., c.s., University of‘lisconsin, IoGraw-Hill Book Company, Inc., 1940, will be indicated hereinafter as “text”. The period of six months to complete the building was arrived at by the colparison of this building with one of comparable size that I followed through to completion. A In a number of instances the complete size of materials were omitted from Specifications and Drawings of the Architect. Due to 11v own inexperience at guessing what was meant, the size of some of the materials I used may not be accurate. 143081 .s'l Hr. ,1 III!!!“ P..—~V.O‘f‘ ‘ I .. I. a.

It is reasonable then to assume the unit costs to be the sane, $5.92 per cu. yd. The labor will also be about the sane as slabs in as such as the pouring of the two is one and the same operation as speci- fied. It would be illogical to charge a different price for the same operation. Porns-dlaterial and Labor II'By using the sheet-steel cores or pans the wood fern material has been reduced very nuch. It is necessary to use wood ferns only on the bottom side of the joist and these forns have already been figured under "Beans”.
