MEASUREMENTS & PAYMENT Sample Clauses

MEASUREMENTS & PAYMENT. Cross section shall be taken normal to the centre line at as close intervals as necessary and practicable, but in any case not more than 5 m. apart prior of starting of excavation. The volume of excavation in soil shall be computed from the cross section taken after deducting the volume of hard rock. All rock excavated shall be stacked in depots and arranged as not to obstruct development of site or building work or construction of roads. Measurements for rock payment will be by depots at least 1 m. high with 40% deduction for voids. The contractor should carry out the excavation work to the levels, spaces, and dimensions as shown or figured on the drawing or as required by the Architect/Consulting Engineers to receive the concrete work. Should any of the excavation be taken down below the proper levels, the contractor shall fill in such excavation at his own expense with M-10 concrete well rammed in the position until it is brought up to the proper level. If the trenches are made broader or longer than directed, the extra breadth and length shall be filled in, after the foundations are built, with earth rammed hard, by the contractor at his own expense and without extra charge. The Contractor shall make provision for all shoring, pumping, dredging or bailing out of water and keep in the trenches free from water while the masonry work is in progress. The contractor shall also, at his own costs, remove such portions of boulders, or rocks as required to make the bottom of the trenches horizontal and levelled, The rate of this item includes the refilling excavated earth in the sides of the masonry or concrete work to the original surface of the ground in 230 mm. layers with watering and ramming. All surplus earth left over shall be either spread or deposited on the site, within a lead as specified in the Bill of Quantities and as directed by Owner/Consulting Engineers, without any extra charge.
