pin having a diameter not less than 7.5 times the bar diameter as shown on the Drawings. Reinforcing bars shall be accurately formed to the shapes and dimensions indicated on the Drawings, and shall be fabricated in a manner that will not injure the materials. (c) Placing Reinforcing bars shall be accurately placed in proper position, and so that they be firmly held during placing of concrete. Bars be tied at all intersections by using annealed iron wire 0.9mm or larger diameter, or suitable clips. Distances from the forms shall be maintained, corrected by means of metal hangers, metal blocks, metal supports or other supports approved by the Engineer. The Engineer shall inspect reinforcing bars after placing. When a long time has elapsed after placing reinforcing bars, they shall be cleaned and inspected again by the Engineer before placing concrete. (d) Splicing and Joint When it is necessary to splice reinforcing bars at points, position and methods of splicing shall be determined based on strength calculations and approved by the Engineer. In lapped splices, the bars shall be lapped by the required length, and wired together at several points by using annealed iron wire larger than 0.9mm. Exposed reinforcing bars intended for bonding with future extensions shall be effectively protected from injury and corrosion. Oxyacetylene welding joint of reinforcing steel shall be done only if authorised by the Engineer in writing. (e) Measurement and Payment Bending and installation of reinforcing bar of piers and abutments shall be measured in terms of tons. The length of steel bar of each size will be shown on the drawings in which the bar length for splicing is excluded. In computing the weight to be measured, the theoretical weights of bars of the cross-section shown on the Drawings or authorised shall be used. These weights are given in the following table: - Bar type and the in millimeters Weight of Bar in 12m length of bar Y10 7.40 Y12 10.66 Y16 18.95 Y20 29.60 Y25 46.30 1703 (C) FORMWORK FOR CULVERT WALLS AND SLABS This work consist of all temporary moulds for forming the concrete for culvert
