2101. DESCRIPTION The work shall cover furnishing and providing plain or reinforced concrete foundation placed in open excavation, in accordance with the drawings and these specifications or as directed by the Engineer. 2102. MATERIALS Materials shall conform to Section 1000 of these <strong>Specification</strong>s. 2103. GENERAL A method statement for construction indicating the following shall be submitted by the Contractor for approval of the Engineer, well in advance of the commencement of open foundation: i) Sources of Materials ii) Design, erection and removal of formwork iii) Production, transportation, laying and curing of concrete iv) Personnel employed for execution and supervision v) Tests and sampling procedures vi) Equipment details vii) Any other point Necessary arrangements for execution under water wherever necessary, shall be included in method statement. Dimensions, lines and levels shall be set out and checked with respect to permanent reference lines and permanent bench mark. 2104. WORKMANSHIP 2104.1. Preparation of Foundations Excavation for laying the foundation shall be carried out in accordance with Section 300 of these specifications. The last 300 mm of excavation shall be done just before laying of lean concrete below foundation. In the event of excavation having been made deeper than that shown on the drawing or as ordered by the Engineer, the extra depth shall be made up with M15 concrete in case of foundation resting on soil and foundation grade concrete for foundations in rock, at the cost of the Contractor and shall be considered as incidental work. Special care shall be taken not to disturb the bearing surface. Open foundations shall be constructed in dry conditions and the Contractor shall provide for adequate dewatering arrangements to the satisfaction of the Engineer. 2104.2. Setting Out The plan dimensions of the foundation shall be set out at the bottom of foundation trench and checked with respect to original reference line and axis. It shall be ensured that at no point the bearing surface is higher than the founding level shown on the drawing or as directed by the Engineer. 2104.3. Construction Where the bearing surface is earth, a layer of M15 concrete shall be provided below foundation concrete. The thickness of lean concrete layer shall be 100 mm minimum unless otherwise specified. No formwork is necessary for the lean concrete layer. For foundation concrete work, side formwork shall be used. Formwork for top of the foundation concrete shall also be provided, if its top has slopes steeper than 1 (vertical) to 3 (horizontal). When concrete is laid in slope without top formwork, the slump of the concrete shall be carefully maintained to ensure that compaction is possible without slippage down the slope of freshly placed concrete. In certain cases it may be necessary to build the top formwork progressively as the concreting proceeds up the slope. Reinforcement shall be laid as shown on the drawing. Before laying of lean concrete layer, the earth surface shall be cleaned of all loose material and wetted. Care shall be taken to avoid muddy surface. If any portion of the surface has been spoiled by over-wetting, the same shall be removed. Concrete M15 shall be laid to the thickness as required. No construction joint shall be provided in the lean concrete. Before laying foundation concrete, the lean concrete or hard rock surface shall be cleaned of all loose material and lightly moistened. Foundation concrete of required dimensions and shape shall be laid continuously upto the location of construction joint shown on the drawing or as directed by the Engineer.
