Concrete for all structures shall have minimum compressive strength <br />at 28 days of 4000 psi unless otherwise indicated on the drawings. <br />3.13 FIELD CONTROL <br />A. The Contractor shall advise the Engineer of his readiness to proceed at <br />least one working day prior to each concrete placement. The Engineer <br />will inspect the preparations for concreting including the preparation of <br />previously placed concrete, the reinforcing and the alignment and <br />tightness of formwork. No placement shall be made without the prior <br />approval of the Engineer. <br />B. The Engineer may have cores taken from any questionable area in the <br />concrete work such as construction joints and other locations as <br />required for determination of concrete quality. The results of tests on <br />such cores shall be the basis for acceptance, rejection or determining <br />the continuation of concrete work. <br />C. The Contractor shall cooperate in obtaining cores by allowing free <br />access to the work and permitting the use of ladders, scaffolding and <br />such incidental equipment as may be required. The Contractor shall <br />repair all core holes to the satisfaction of the Engineer. The work of <br />cutting and testing the cores will be at the expense of the Owner if <br />cores test satisfactorily and will be at the expense of the Contractor if <br />cores test unsatisfactorily. <br />END OF SECTION <br />1 09/03 03300 -17 03- 3148.A -R <br />
