Prime surfaces to receive the fluidapplied waterproofing membrane. Apply the primer as required by the membrane manufacturer’s printed instructions. Over the primed surfaces, provide a uniform, monolithic coating of fluidapplied membrane, 60 mils thick, plus or minus 5 mils thick, by following the manufacturer’s printed instructions. Apply material by trowel, roller, brush, spray apparatus, or other method acceptable. Check wet film thickness as specified under Field Tests, and adjust application rate as necessary to provide a uniform coating of the thickness specified. Where possible, mark off the surface to be coated in even units to facilitate proper coverage. At expansion joints, control joints, prepared cracks, and termination, carry the membrane over the preformed elastomeric sheet in uniform 60 mils thick, plus or minus 5 mils, wet thickness to provide a monolithic coating. When work has stopped long enough for the membrane to cure, begin the next application by wiping the previously applied materials with a solvent so that accumulated dirt and dust, which could inhibit adhesion of the overlapping membrane coat, is removed. Use solvent recommended by the membrane manufacturer, as approved.

Availability of approved drawings, Method Statements and Work shall not begin until all the required submittals have been accepted 2. ACTIVITIES 1
Mock up 2. ACTIVITIES 3 Installation of steel casing (length, Dia. And verticality / All permanent structural casing shall be of steel conforming to ASTM A36/A36M or ASTM A252 Gr. 2 unless specified otherwise in the Drawings /All splicing of permanent structural casing shall be in accordance with Article 6.13.3, "Welded Connections," of the AASHTO LRFD Bridge Design Specifications. Borehole drilling and cleanliness / The Contractor shall use appropriate means, such as a cleanout bucket, air lift, or hydraulic pump, to clean the bottom of the excavation of all bored piles
Drilling depth / tape with a heavy weight attached to the end of the tape, or other means acceptable to the Engineer to determine that the shaft bottom meets the requirements in the Contract Bentonite slurry testing (spec. gravity., marsh viscosity, PH, dosage / Bentonite Suspension must conform to the following specifications stated in TS 204.3.7 Drilling depth / the base of the excavation shall be covered with not more than 12.5mm for 50 percent of the base area of sediment or loose or disturbed material just prior to placing concrete. Placing of sediments or Disturd material / or wet bored pile excavations in soils, the base of the excavation shall be covered with not more than 75mm of sediment or loose or disturbed material just prior to placing concrete. For dry bored pile excavations in soils, the base of the excavation shall be covered with not more than 37.5mm sediment or loose or disturbed material just prior to placing concrete 2.

Delivery of concrete and testing of fresh concrete and Concrete used in the construction of bored piles shall conform to Section 206.4 Laboratory testing cylinder Placing of concrete / The concrete shall be placed such that the free fall is vertical down the center of the shaft without hitting the sides, the steel reinforcing bars, or the steel reinforcing bar cage bracing. Curing / After placement, the temporarily exposed surfaces of the shaft concrete shall be cured in accordance with the provision in Section 206.13
Removal of steel casing / Casing extraction shall be at a slow, uniform rate with the pull in line with the axis shaft. Excessive rotation of the casing shall be avoided to limit deformation of the reinforcing steel cage. 2. ACTIVITIES 5
Crosshole sonic tubes( number, diameter and cleanliness of tubes) / Access tubes for crosshole sonic log testing shall be steel pipe of 3.6mm minimum wall thickness and at least 38.1mm inside diameter. Crosshole sonic logging test on hardened bored pile / The access tubes shall have a round, regular inside diameter free of defects and obstructions Grouting of crosshole sonic tubes / Grout for filling the access tubes at the completion of the cross-hole sonic log tests shall be a neat cement grout with a maximum water/cement ratio of 0.45. All bleed water is to be removed and the access tubes topped up with grout. 2. ACTIVITIES 6
Initial load testing / The initial load test shall be cyclic load test for the test piles deriving strength from end bearing and side friction. The maintained load test can be performed for end bearing piles which do not rely on friction and for piles socketed in rock. Initial load test shall be referred to Static Load Test in Section 204.2.6.2. Static load testing / The static load test shall follow the procedures specified in ASTM D1143/D1143M, and the loading procedure should follow the Quick Load Test Method, unless detailed longer-term load-settlement data are needed, in which case the standard loading procedure should be used
