Protection of Existing Structures. Monitor structures for settlement that are within a distance of ten Compacted Aggregate Pier diameters or the estimated Compacted Aggregate Pier depth, whichever is greater, in a manner approved by the Engineer. Record elevations to an accuracy of 0.01 foot (3 mm). Record elevations before construction begins, after completion, or as directed by the Engineer. Document thoroughly the condition of the structures with descriptions and photographs made both before and after Compacted Aggregate Piers are constructed. Document all existing cracks, and provide copies of all documentation to the Engineer. At any time settlement of 0.05 foot (15 mm) or damage to the structure is detected, immediately stop the source of vibrations, backfill any open excavations and contact the Engineer for instructions.
Protection of Existing Structures. Contractor shall protect existing structures, walks, curbs, pavements, roads, trees, landscaping, survey markers, monuments, or other devices marking property boundaries or corners, and/or improvements in working areas, utilities, and adjoining property (including, without limitation, protection from settlement or loss of lateral support). Contractor shall replace same at his expense with same kind, quality, and size of Work or item if temporary removal is necessary, or damage occurs due to the Work. Water Quality. Contractor shall comply with all applicable water quality laws and regulations, including permitting, monitoring, and reporting of storm water discharge applicable to the Work, at no additional cost to District. Contractor shall indemnify and hold district harmless from loss, cost, or liability arising out of Contractor’s violation of such laws or regulations.
Protection of Existing Structures. All existing pipes, poles, wires, fences, curbing, property line markers and other structures which the Engineer decided must be preserved in place without being temporarily or permanently relocated, shall be carefully supported and protected from injury by the Contractor. Should such items be injured, they shall be restored by the Contractor, without compensation, to at least as good condition as that in which they were found immediately before the work was begun.
Protection of Existing Structures. Contractor shall protect existing structures, walks, curbs, pavements, roads, trees, landscaping, survey markers, monuments, or other devices marking property boundaries or corners, and/or improvements in working areas, utilities, and adjoining property (including, without limitation, protection from settlement or loss of lateral support). Contractor shall replace same at his expense with same kind, quality, and size of Work or item if temporary removal is necessary, or damage occurs due to the Work.
Protection of Existing Structures. The Contractor shall implement best management practices (BMPs) to protect existing structures within and immediately adjacent to the Work Area at all times. Existing structures include but are not limited to geotubes, armor mat, pilings, rock jetty, and subsidence monitoring control stations. The Contractor shall exercise due caution when working near structures so as not to damage the structures. The Contractor will be responsible for the cost to repair any damage to existing structures caused by the Work. Final payment shall be withheld until the repairs are made and approved by the Owner. Any existing structures such as pilings, signs, barricades, fencing, etc. that must be removed from the Work Area by the Contractor to conduct the Work shall be surveyed in accordance with TS-6, photographed, and recorded in a log prior to removal. The Contractor shall be required to reinstall any structures removed for construction prior to demobilization. Any existing structure removed by the Contractor shall be replaced with the same size and type of material as the original materials or equivalents approved by the Owner and Engineer. Replaced structures shall be installed to the same penetration depth as the original and shall extend to the original height above grade. All expenses associated with the removal, replacement, and reinstallation, should be included in Bid Item No. 1, “Mobilization and Demobilization”. Specific to the vehicular traffic barricade pilings existing between Stations 128+00 to 159+00, the Contractor shall be required to replace any of these piling removed to conduct the Work. Pilings that are not a hindrance to construction may be left in place if the height of the top of piling above the final construction grade is a minimum of four (4) ft. Pilings that are removed to facilitate construction shall be replaced with material of the same size and type. Embedment and the height of the top of structure above the final construction grade shall be the same as that surveyed of the original piling at pre-construction grade provided that the height of the top of piling above the final construction grade is a minimum of four (4) ft. Refer to TS-6 for surveying requirements.
Protection of Existing Structures. Monitor structures for settlement that are within a distance of ten pile diameters or the estimated pile depth, whichever is greater, in a manner approved by the Engineer. Record elevations to an accuracy of 0.01 foot (3 mm). Record elevations before construction begins, after completion, or as directed by the Engineer. Document thoroughly the condition of the structures with descriptions and photographs made both before and after H-pile supported LTP is constructed. Document all existing cracks, and provide copies of all documentation to the Engineer. At any time settlement of 0.05 foot (15 mm) or damage to the structure is detected, immediately stop the source of vibrations, backfill any open excavations and contact the Engineer for instructions.
