Pier installation shall follow the requirements of ACI 336.1, Reference Specifications for the Construction of Drilled Piers. 2C.6.2 Drilling Foundation piers shall be drilled with an auger in earth and with an auger with hardened teeth suitable for drilling rock or a core drill as required depending on hardness. Casings shall be used where the sides of the excavation are unstable and may be used at all locations. A pier excavation will be considered dry if the infiltration of ground water from a source at or near the bottom is at a rate of less than 1/2 inch rise per minute at the bottom of the pier. The total theoretical height of water in the bottom of the pier may not exceed 6 inches at the time sufficient concrete has been placed to balance the water head. Drilling equipment shall be designed to drill straight and clean holes. Casings, if used, shall be installed as the drilling proceeds or immediately after the auger is withdrawn as required to prevent sloughing and caving of the excavation walls. The Contractor may elect to advance the excavation and facilitate the removal of cuttings by utilizing a densified fluid. All loose material shall be removed from the bottom of the pier excavations. Casings shall be of steel construction and shall be of ample strength to withstand handling and installation stresses. Casings may be removed as the concrete is placed or left in place at the Contractor's option. During removal the casing shall be continually plumb and the concrete surface within the casing shall be continually observed for maintenance of concrete "head" sufficient to offset the casing's external water head. A minimum head of 4 to 5 feet of concrete shall be maintained above the bottom of the casing during casing extraction. Casings left in place shall not be exposed above grade. Each pier shall be accurately located, sized, and plumbed. The maximum variation of any pier from its designated location shall not be more than 2 inches at its top elevation. No pier shall be out of plumb more than one inch in 5 feet of height. Variation of pier location within specified limits shall not be cause for variation in anchor bolt or concrete cap location. Each pier excavation shall be made to the depth indicated on the drawings. 2C.6.3 Placing of Concrete Concrete work for foundation piers shall conform to the requirements of Section 2C.5 and to these additional requirements. Unless otherwise permitted by the Owner, concrete shall be placed in the pier holes the same day the holes are drilled. City of Fort Collins Power & Light-06.007 2C-13 All water and loose materials shall be removed from the holes and pier reinforcing shall be thoroughly cleaned before any concrete is placed. Pier holes shall be dry when concrete is placed unless otherwise acceptable to the Owner. Concrete shall be placed with a tremie or funnel, or pumped to prevent segregation and the top 6 feet shall be rodded or vibrated to provide a dense mass free of voids. During the filling of the holes, if water begins to accumulate on the top of the concrete, the placement shall be suspended and the water removed before placement resumes. If water continues to accumulate during the suspension of placement, the concrete placed shall be removed and the pier shall be installed by underwater methods. Should there be an accumulation of scum or laitance on the top of the concrete, it shall be removed and additional concrete shall be placed to bring the pier back to the proper elevation. Pumping methods shall conform to ACI 304, Chapter 9. The maximum loss of slump due to pumping shall be 2 inches. Aluminum or aluminum alloy pipes shall not be used to convey pumped concrete. After the concreting is started for each pier, it shall be completed in a continuous process. A sufficient quantity of concrete to fill the pier shall be in delivery trucks at the pier site when the first concrete is placed in each pier. If the concreting of any pier is suspended for more than 30 minutes before the pier is completed, laitance and water shall be removed from the joint surface and the joint surface shall be coated with epoxy bonding compound before concreting is resumed. In order to provide for an emergency stoppage, bonding compound shall be at the site before the concreting of piers is started. Piers shall be reinforced as indicated on the drawings and all reinforcements shall be installed and secured to prevent shifting during the placement of concrete. The upper portion of the piers shall be formed where indicated on the drawings. Each pier shall be cured for at least 7 days by continuous saturation with water or the use of membrane curing compound as specified in Section 2C.5.12. If casings are to be left in place, the void areas between the form and the excavation walls shall be filled with grout. The grout shall be placed and compacted in such a manner that the annular space is completely filled. Records shall be kept by the Contractor indicating the exact volume of each pier excavated and this volume shall then be compared to the volume of concrete actually placed in each pier. A lesser amount of concrete placed than calculated may indicate fault pier construction. In the event of such an occurrence, the Owner shall be notified, and immediate remedial action shall then be taken by the Contractor. City of Fort Collins Power & Light-06.007 2C-14 2C.6.4 Underwater Concrete Concrete shall not be deposited under water except with specific permission of the Owner. For concrete deposited under water the limiting requirements shall be adjusted to provide not more than 6 inches of slump and to increase the cement content by one sack per cubic yard. Any extra charges for these changes by the concrete supplier shall be borne by the Contractor. Underwater concrete shall be placed through 12 inch or larger tremies having a tremie seal at the lower end and a hopper at the upper end. Before the flow of concrete is started, water shall be kept out of the tremie by means of a suitable bottom closure. After the flow of concrete is started, the lower end of the tremie shall be kept below the surface of the deposited concrete. Agitation of the deposited concrete shall be avoided. When necessary to move laterally, the tremie shall be lifted free of the concrete and lowered vertically at the new location. The entire mass of concrete shall be placed as quickly as possible so that it will flow into place without the necessity of horizontal shifting below water. The water shall be quiescent when concrete is deposited therein. After placing, the ground water level in the area adjacent to the pier shall be kept static until the concrete has taken its initial set. 2C.7 GROUTING 2C.7.1 General This section covers materials and procedures for grouting equipment and structural base plates as required on the drawings.
