PART 3 - EXECUTION

3.1 PREPARATION

A. Protect structures, utilities, pavements, cemetery improvements, drainage facilities, and other facilities from damage caused by settlement, lateral movement, undermining, washout, erosion, flooding, and other hazards created by dewatering operations.

1. Prevent surface water, subsurface water, and groundwater from entering excavations and trenches, from ponding on prepared subgrades, and from flooding the site or surrounding areas.

2. Protect subgrades and foundation soils from softening and damage by rain, groundwater, pond water, or other water accumulation.

B. Install and maintain dewatering systems and temporary water control measures to minimize interference with cemetery operations, construction access, pedestrian access, vehicular circulation, and adjacent occupied or used facilities.

C. Provide temporary grading, berms, diversions, pumps, hoses, discharge piping, filter bags, settling areas, stone aprons, check dams, or other temporary measures necessary to facilitate dewatering and control surface water.

D. Protect and maintain temporary erosion and sedimentation controls specified in Section

312513 – Erosion and Sediment Control during dewatering operations.

3.2 INSTALLATION

A. Install dewatering system utilizing pumps, hoses, temporary piping, sumps, trenches, filters, sediment-control devices, energy dissipation measures, and other methods selected by the

Contractor and acceptable for the conditions encountered.

B. Use filters, intake protection, filter bags, sediment basins, settling tanks, stone check dams, or other means to prevent discharge of sediment-laden water and to prevent pumping of fine sands or silts from the subsurface.

C. Provide sumps, sedimentation tanks, filter bags, stabilized outlets, and other flow-control devices as required by site conditions, the Contract Documents, permits, and authorities having jurisdiction.

D. Provide standby equipment on-site, installed or available for immediate operation, to maintain dewatering on a continuous basis if any part of the system becomes inadequate or fails.

3.3 OPERATION

A. Operate dewatering and temporary water control systems continuously as required until storm drainage pipe, structures, embankment fill, pavement subbase, and related Work have been constructed, or until dewatering is no longer required.

B. Operate systems to lower and control water to permit excavation, trenching, structure installation, pipe installation, embankment reconstruction, fill placement, backfilling, and compaction on dry and stable subgrades.

1. Do not permit pumping operations that lead to loss of fines, soil piping, subgrade softening, slope instability, or damage to adjacent improvements.

2. Do not place bedding, pipe, structures, fill, or backfill in standing water or on softened, unstable, or disturbed subgrade.

C. Dispose of water removed by dewatering in a manner that avoids endangering public health, property, cemetery operations, adjacent properties, and portions of Work under construction or completed. Dispose of water and sediment in a manner that avoids inconvenience to others.

D. Remove dewatering systems and temporary water control measures from Project site on completion of dewatering. Restore areas disturbed by installation, operation, or removal of dewatering systems.

E. Pond Drainage and Drawdown: Where pond drainage or drawdown is required to perform the

Work, provide pumps, hoses, intake protection, discharge piping, sediment controls, energy dissipation, and other temporary measures required to lower and control the pond water level.

Discharge water only to locations shown on the Drawings or approved by the Engineer. Do not discharge water in a manner that causes erosion, sedimentation, flooding, damage to existing improvements, or violation of applicable permits.

F. Trench Dewatering: Keep trenches and excavations free of standing water during excavation, bedding placement, pipe installation, structure installation, backfilling, and compaction. Do not place bedding, pipe, structures, fill, or backfill in standing water or on softened, unstable, or disturbed subgrade. Remove and replace unsuitable or softened material caused by water control operations as directed by the Engineer.

G. Discharge and Sediment Control: Dewatering discharge shall comply with Section 312513 –

Erosion and Sediment Control. Provide temporary sediment basins, filter bags, check dams, stone aprons, stabilized outlets, energy dissipation, or other measures as required to prevent erosion and sediment discharge. Do not discharge turbid or sediment-laden water directly to the pond, wetlands, storm drainage system, watercourses, or adjacent properties.

3.4 FIELD QUALITY CONTROL

A. Monitor dewatering operations to verify that water control measures are functioning as intended and that excavations, trenches, subgrades, and adjacent improvements remain stable.

B. Provide continual observation to ensure that subsurface soils are not being removed by dewatering operations.

C. Promptly notify Engineer if dewatering operations cause or appear likely to cause erosion, sediment discharge, soil piping, instability, settlement, damage to existing improvements, or other adverse conditions.

D. Prepare reports of observations when requested by Engineer.

3.5 PROTECTION

A. Protect and maintain dewatering systems, temporary water control measures, discharge routing, erosion controls, and sediment controls during dewatering operations.
