648 – Streambed Simulation

Description

648.01 This work consists of placing rock and fill to simulate a natural streambed, profile and cross section though road stream crossings. The placement of Channel Rock for: fish rest stop, rock bands, rock weirs, stream bank rocks, and other in stream rock structures, is included within this specification.

Material

648.02 Conform to the following Subsections.

Foundation Fill 704.01

Stream Bed Simulation Material 705.07 Channel Rock 705.08

Construction Requirements

648.03 General. Place streambed simulation material on a prepared surface to form a well-graded, low permeability mass, similar in appearance and texture to the natural streambed. Do not drive metal track or rubber tired equipment directly on metal or concrete structure surfaces.

648.04 Placed Streambed Simulation Material and Channel Rock.

(a) Method A, Machine Placed. Place stream simulation rock in one or more layers with a layer depth less than 1 ½ times the maximum dimension of the stream simulation rock. Place stream simulation by methods that do not cause segregation or damage to the prepared surface. Place or rearrange individual rocks by mechanical methods to obtain a compact low permeability mass matching streambed simulation details. Fill voids before placing the next lift. Place fish rest stop, rock bands, rock weirs, stream bank rocks, and other in stream rock structures as designated.

(b) Method B, End Dumped. Dump stream simulation rock in one or more layers with a layer depth less than 1 ½ times the maximum dimension of the stream simulation rock.

Distribute larger rocks throughout the mass of stone. Obtain a uniformly dense, compact, low permeability bed with a surface matching stream simulation bed details. Fill voids before placing the next lift. Place fish rest stop, rock bands, rock weirs, stream bank rocks, and other in stream rock structures as designated.

(c) Method C, Hand Placed. Place stream simulation rock using hand labor. Material may be hand carried, or carried in wheelbarrows and end dumped to obtain its full thickness. Compact each load using hand operated or hand operated mechanical equipment to obtain a uniformly dense, compact, low permeability bed with a surface matching stream simulation bed details. Fill voids before placing the next lift. Place fish rest stop, rock bands, rock weirs, stream bank rocks, and other in stream rock structures as designated.

648.04 Foundation fill. Fill all voids left during placement of Channel Rocks and Streambed Simulation adjacent to footings, concrete structures or corrugated pipes with foundation fill. Use water pressure, metal tamping rods, and similar hand operated equipment to force material into all surface and subsurface voids between the structure and rocks and between individual rocks.

648.05 Acceptance. Placing streambed simulation material will be evaluated under Subsections 106.02 and 106.04.

Measurement

648.06 Measure the items listed in the bid schedule according to Subsection 109.02.

Payment

648.07 The accepted quantities, measured as provided in Subsection 109.02, will be paid at the contract unit price per unit of measurement for Section 648 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section.
