Earth Works In Industry

By Ricky Andrews


At his discretion the Superior may check the Vendor's setting out, but any such check by the Superior will not relieve the Vendor of his responsibility to prepare the projects. On completion of setting out each portion of the Projects the Vendor will notify the Superior, and will obtain the Superior's permission to proceed with excavation.

At an employee's discretion they may check the Supplier's setup, but any such check will not remove liability from the contracting company. Should the Supplier be given authority to proceed, this will in no way relieve the Supplier of his responsibility to prepare the Works. The supplier will be responsible for determining the location of any underground services (e.g. power cables, pipelines, telephone cables), in the location of excavation and will ensure that all such services are protected from destruction or displacement during the source of the Work.

The Contractor shall carry out all excavation under well drained conditions. The contractor shall perform all work necessary to protect the excavation and other works from flooding by rain water, ground water or plant process liquors. Adequate pumping facilities shall be provided and operated to maintain excavations in a dry condition suitable for placement of concrete or the installation of other items. Pumps shall not discharge into existing operating areas of the plant nor on to adjacent work areas.

Adequate pumping facilities will be provided and operated to maintain excavations in a dry condition adequate for placement of concrete or the installation of other items. The supplier will perform all work necessary to protect the excavation and other works from flooding by rain water, ground water or plant process liquors. Excavations will be accurately finished to lines, levels and grades as shown on the plans. Filling will be at the Supplier's expense except when otherwise approved by the Supervisor.

Should any destruction occur all associated repair cost will be at the Vendor's cost. Excavations will be accurately finished to lines, heights and grades as shown on the plans. The Vendor will carry out all excavation under well drained circumstances. The vendor will perform all project necessary to protect the excavation and other projects from flooding by rain water, ground water or plant process liquors. Adequate pumping facilities will be provided and operated to maintain excavations in a dry condition adequate for placement of concrete or the installation of other items.

The bottoms of completed excavations shall be kept free and cleaned of loose material, water, other liquid and rubbish and shall be kept free from trafficking. The bases of completed excavations shall be inspected by the Superintendent to determine whether the exposed material is suitable or unsuitable for the required bearing purpose. Additional excavation may be directed by the Superintendent.
