Right of way and compaction requirements

Generally, those that can apply significant amounts Right of way and compaction requirements shear as well as compressive stress, are most effective. These specifications are generally recommended by a geotechnical engineer in a geotechnical engineering report.

Provide barricades and restrict access as appropriate to prevent damage to Work in place. When located within the bioretention cell, rain garden or permeable pavement footprint the service shall be relocated to route under the bioretention section and supporting infrastructure i.

Side sewers and service drains shall be designed and installed in accordance with the City of Seattle Standard Plans and Specifications. The ability of the first fill layers to be properly compacted will depend on the condition of the natural material being covered. Relocating hydrants typically requires full replacement of hydrant lateral piping to the water main.

Excavation for manholes, concrete valve boxes, and similar structures shall be sufficient to leave at least 12 inches in the clear between the outer surfaces and the embankment or timber that may be used to hold and protect the banks.

Shall be accomplished by the use of sheeps-foot rollers, pneumatic tire rollers, vibrating rollers, or other mechanical tampers of a size and type necessary to achieve the required degree of compaction. Consists of preparing an acceptable pipe foundation, excavating the pipe groove in the prepared foundation and backfilling from the foundation to 12 inches above the top of the pipe.

Trench support system shall be suitable for the soil structure, depth of cut, water content of soil, weather conditions, superimposed loads, vibration. Side sewers and service drains are owned and maintained by the property owner.

Soil compaction

Generally all the cells include: Using a movable trench box built-up of steel plates and a heavy steel frame of sufficient strength to resist the pressures surrounding the excavation. Trenches shall be backfilled to the proper surface with material as shown or specified.

The term bioretention is used to describe various designs using soil and plant complexes to manage stormwater. 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.

Kneading - shear is applied by alternating movement in adjacent positions.

Midvale, UT

Additional information is available in Seattle Municipal Code: All damage, injury or loss resulting from lack of adequate sheeting, bracing, and shoring shall be the responsibility of the Contractor; and the Contractor shall effect all necessary repairs or reconstruction resulting from such damage.

If the bioretention cell is lined, provide the following horizontal clearances between the root ball of the new tree and the outside of the liner: The construction plant available to achieve compaction is extremely varied and is described elsewhere.

Backfill around valves with Granular Backfill Material. Wherever the trench subgrade material does not afford a sufficiently solid foundation to support the pipe and superimposed load, and where groundwater must be drained, the trench shall be excavated below the bottom of the pipe to such depth as may be necessary, and this additional excavation filled with clean, compacted sewer rock.

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. Vibrating - a stress is applied repeatedly and rapidly via a mechanically driven plate or hammer.

Often combined with rolling compaction see below. Roller-compactors are often fitted with Right of way and compaction requirements devices to enhance their effectiveness. Design information and figures showing design requirements for rain gardens are included in Section 5. Sloping sides of trench to the angle of repose at which the soil will remain safely at rest.

Permeable pavement systems can be designed to provide differing degrees of flow control. In planted or unimproved areas: Hydrants Provide minimum 3 feet of cover over pipe to hydrant.

These areas will be indicated by the development of ruttingpumping, or ground weaving. The Stormwater Code differentiates between projects on private property and projects in the right-of-way. Gravel road base subgrade d.

The bottom of the trenches shall be accurately graded to provide uniform bearing and support for each section of the pipe along the entire length of the barrel of the pipe. Shall be free from alkali, salt, and petroleum products, roots, sod, limbs, and other vegetative matter, slag, cinders, ashes and rubbish, or other material that in the opinion of the Engineer may be objectional or deleterious.

From centerline of watermain: The approximate location and number of such tests shall be as shown on the drawings, as described in the Bid Form, or as selected by the Engineer. Top of bituminous surface course D. Contractor may select one of the following methods of ensuring the safety of workers in the trench, as approved by the Utah State Industrial Commission or its safety inspectors:with standards and requirements for compaction, backfill and pavement restoration and resurfacing that ensures the best possible restoration of the paved surface over and adjacent to the trench”, Right-of-Way Ordinance No.

B. Placement of Hot Mix Asphalt does not meet the minimum compaction requirements of the current WSDOT Standard Specifications for Road, Bridge and Municipal Construction and the Standard Plans.

C. Differential settlement occurs within an excavation or roadway subgrade during the warranty period. additional compensation due to the testing requirements specified herein. b. At the start of the trenching operation, the Contractor shall demonstrate to the of compaction to be used with this equipment to achieve the required compaction.

Adjustments to sanitary sewers within the County right-of-way may be. Right-of-Way/Easement Work Permit Applications must be submitted to the City of Othello Public Works Department no later than two (2) business days prior to the anticipated project start date. All work within public right-of-way must be completed in Compaction Report(s) Required: Yes No Compaction Requirements: Comments.

to clear the right-of-way in preparation for construction. This consistworks of the removal and disposal of all vegetation and debris within the limits of construction which is in the way of the construction work. Any items within the right-of-way that are designated to remain in.

right-of-way management representative is responsible for determining that adequate and requirements of the National Electrical Safety Code will be met. Earth compaction is unsuitable for drainfield construction.
