The contractor shall do all ditching, pumping, well pointing and bailing, build all drains and do all other work necessary to keep the excavation clear of ground water, sewage or storm water during the progress of the work and until the finished work is safe from injury.
Where the excavation is wet sand and suitable construction conditions cannot be obtained by other methods, the contractor shall install and operate, at no additional compensation, a pumping system connected with well points, so as to drain the same effectually. No masonry or pipe shall be laid in water, and water shall not be allowed to rise over masonry until concrete or mortar has set at least forty-eight hours. All water pumped or drained from the work shall be disposed of in a manner satisfactory to the Engineer without damage to adjacent property or to other work under construction. Necessary precautions shall be taken to protect all construction against flooding.
