Slurry temperature shall be at least 40°F when tested. Water Slurry At the option of the Contractor, water may be used as slurry when casing is used for the entire length of the drilled hole. Water slurry shall be tested for conformance to the requirements shown in the following table: WATER SLURRY PROPERTY REQUIREMENT TEST Density (pcf) - before cleaning - just before placing concrete 63.5* Mud Weight (Density) API 13B-1 Section 1 Sand Content (percent) - before final cleaning -just before placing concrete less than or equal to 0.5 Sand API 13B-1 Section 5 *When approved by the Engineer, salt slurry may be used and the allowable densities may be increased up to 2 pcf. CONSTRUCTION General CIDH concrete piling 24 inches in diameter or larger may be constructed by excavation and depositing concrete slurry. CIDH concrete piling (rock socket) shall consist of drilling or coring sockets in rock to the depths or lengths specified and filling the sockets with reinforced concrete. Cored holes shall conform to the provisions of Section 49-4.03, "Drilled Holes," of the Standard Specifications. Disposal of drill cuttings shall conform to the provisions in of these special provisions.
At the Contractor's expense, additional installation tension tests, tests required to determine job inspecting torque, and rotational capacity tests shall be performed by the Contractor on each rotational capacity lot, in the presence of the Engineer, if: 1. Any fastener is not used within 3 months arrival on the job site, 2. Fasteners are improperly handled, stored, or subjected to inclement weather prior to final tightening, 3. Significant changes are noted in original surface condition of threads, washers, or nut lubricant, or 4. The Contractor's required inspection is not performed within 48 hours after all fasteners in a joint have been tensioned. Failure of a jobsite installation tension test or a rotational capacity test will be cause for rejection of unused fasteners that are part of the rotational capacity lot. When direct tension indicators are used, installation verification tests shall be performed in conformance with Appendix Section X1.4 of ASTM Designation: F 959, except that bolts shall be initially tensioned to a value 5 percent greater than the minimum required bolt tension. SURFACE PREPARATION For all bolted connections, the contact surfaces and inside surfaces of bolt holes shall be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions. SURFACE PREPARATION For all bolted connections the following be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions: 1. Contact surfaces, 2. surfaces of existing members that are within the grip and will be hidden by surfaces of outside existing members within the grip under bolt heads, nuts, and washers, and 3. Inside surfaces of bolt holes. SURFACE PREPARATION For all bolted connections, the new contact surfaces and inside surfaces of bolt holes shall be cleaned and coated before assembly in conformance with the provisions for cleaning and painting structural steel of these special provisions.
CONSTRUCTION For standards located in sidewalk areas, the pile foundation must be: 1. Placed to final sidewalk grade before the sidewalk is placed 2. Square for the top 4 inches Use sleeve nuts on Type 1-A 1-B standards. The bottom of the base plate must be flush with finished grade. PAYMENT Payment for cast-in-drilled-hole concrete pile foundations conform to the provisions in Section 86-8, "Payment," of the Standard Specifications. 103.__ STANDARDS, STEEL PEDESTALS, AND POSTS Standards, pedestals, and posts for traffic signal and lighting standards shall conform to the provisions in Section 862.04, "Standards, Steel Pedestals and Posts," of the Standard Specifications, "Steel Structures" of these special provisions, and the following requirements. Steel bolts not designated on the plans as highstrength (HS) or stainless steel shall be for general applications and shall conform to the requirements in ASTM Designation: A 307. Anchor shall conform to the requirements in ASTM Designation: F 1554, Grade 36. High-strength (HS) anchor bolts shall conform to the requirements in ASTM Designation: F 1554, Grade 105. Where the plans refer to the side tenon detail at the end of the signal mast arm, the applicable tip tenon detail may be substituted. The sign mounting hardware shall be installed at the locations shown on the plans. The sign panels will be State furnished in conformance with the provisions in "Materials" of these special provisions.
