CAST -IN-PLACE CONCRETE Section 03300 15-1207 B. The Owner reserves the right to survey the slabs, if the slabs are determined to be outside of the maximum tolerance for slab flatness. If the slabs are found to be out of tolerance, then the Contractor will be required to bring the slabs to within tolerance by either grinding and filling or replacing the slab. Repair methods proposed by the Contractor must be acceptable to the Owner and Architect. The Contractor will be responsible for reimbursing the Owner for any surveying costs incurred. Determination of slab flatness, surveying and any remedial work must be completed far enough in advance of the scheduled date for installation of the floor finishes so that the project schedule is maintained, delays are avoided and the new slabs or slab repairs are properly cured. C. As directed by Architect, cut out and replace defective concrete. All defective concrete shall be removed from the site. No patching is to be done until surfaces have been examined by Architect and permission to begin patching has been provided. D. Permission to patch any area shall not be considered waiver of right, by the Owner, to require removal of defective work, if patching does not, in opinion of Architect, satisfactorily restore quality and appearance of surface. E. Defective concrete is: 1. Concrete that does not match the approved mix design for the given installation type. 2. Concrete not meeting specified 28 -day strength. 3. Concrete which contains rock pockets, voids, spalls, cracks, exposed reinforcing, or other such defects which adversely affect strength, durability or appearance. 4. Concrete which is incorrectly formed, out of alignment or not plumb or level. 5. Concrete containing embedded wood or debris. 6. Concrete having large or excessive patched voids which were not completed under Architect's direction. 7. Concrete not containing required embedded items. 8. Excessive Shrinkage, Cracking, Crazing or Curling; Defective Finish: Remove and replace if repair to acceptable condition is not feasible. F. Patching: Install specified Patching Mortar per manufacturer's recommendations. REPAIRS TO DEFECTIVE CONCRETE WHICH AFFECT THE STRENGTH OF ANY STRUCTURAL CONCRETE MEMBER OR COMPONENT ARE SUBJECT TO APPROVAL BY THE ARCHITECT AND DSA. 3.07 INSPECTION A. There will be initial or preliminary inspection of the finished concrete slabs by the Project Inspector and/or Architect for flatness. If deemed necessary, the Owner reserves the right to have a survey performed by a registered surveyor or testing lab. If it can be determined that floors not meeting the flatness criteria is due to means and methods fully within the control of the Contractor, the cost of the survey will be back charged to the Contractor. This includes, but is not limited to the erection of steel and metal deck outside industry tolerances and referenced standards. 3.08 CONCRETE TESTING A. Comply with CBC Section 1903A, 1905A.3, 1916A and as specified in B. below. Costs of tests will be borne by the Owner. 10
