Watermains -3ft- 0in 10"— 12" dia. Bell holes shall be dug after the trench bottom has been graded. Unless otherwise indicated, trenches shall be graded to avoid high points with the necessity of placing vacuum and relief valves in the water lines.
Compaction is accomplished by use of heavy equipment. Use on-site materials only if specified compaction requirements can be met. Place bioretention cells and rain gardens such that settlement monitoring would not be required during construction. In construction[ edit ] Soil compaction is a vital part of the construction process.
Surface Treatments and Pavements The Contractor shall do all pumping, shall build all drains and do all the work necessary to keep the trench and pipes free from water during the progress of the work.
Shall be provided for improved streets and alleys and shall include catch basins and inlets that discharge to a public combined sewer, public storm drain, or other discharge point approved by Seattle Public Utilities SPU.
Maintain standard cover and clearances.
Minimum pipe diameter is 8 inches Manholes are required every feet. Not allowed within footprint of bioretention cell.
Maintain standard clearance from other utilities. He shall select the methods to be used and carefully perform the work of backfilling and compaction so as to prevent damage to new or existing piping. The width of trench, measured at the top of the pipe, shall be as narrow as possible but not wider than 15 inches on each side of sewer or water pipe.
The trenches shall not be backfilled until the utilities systems as installed conform to the requirements of the Drawings and Specifications. If section of underdrain pipe is solid wall then provide minimum three-foot horizontal separation between new street tree and underdrain pipe.
Water Mains Pipe cover: Provide access to the work and all men and machinery necessary to aid the testing laboratory personnel in performing field density tests or taking samples for laboratory tests.This section analyzes the basic right-of-way width requirements for conventional cross-country pipeline construction and recommends the use of a series of standard baseline right-of-way widths.
In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densification as air is displaced from the pores between the soil grains.
When stress is applied that causes densification due to water (or other liquid).
