2547.01 DESCRIPTION.
This work shall consist of the construction, use, maintenance and removal of temporary structures used to provide construction access across along or into waters of the United States. Temporary structures are any features not a part of the completed project that are constructed or installed to provide access to the project site including stream crossings, causeways, pads and temporary bridges or barges. The type of structure used, if any, is at the Contractor’s discretion provided it complies with Article 1105.14.

Unless indicated otherwise in the contract documents, the Contracting Authority will obtain approval for temporary stream crossings, constructed in accordance with Standard Road Plan RL-16 or as shown in the contract documents, in the Section 404 permit. The Contractor shall obtain a Section 404 permit for temporary stream crossings not to be constructed in accordance with RL-16 or the contract documents.

2547.02 MATERIALS.
Fill materials shall be furnished by the Contractor and shall not be obtained from the stream unless specifically allowed elsewhere in the contract documents. All fill material shall be clean with less than 10% fines passing the #200 sieve, broken concrete (with no exposed rebar), revetment, or granular materials.

Material used for armoring shall be Class D or Class E revetment, or broken concrete with no exposed steel.

2547.03 CONSTRUCTION.
Temporary structures shall not restrict expected high flows or disrupt the movement of aquatic life native to the stream or water body, and shall not extend over 100 feet (30 m) into any swamp, bog, marsh, or similar area that is adjacent to the stream or water body. Expected high flows are those flows which the Contractor expects to experience during the period of time that the crossing is in place. Pre-construction downstream flow conditions shall be maintained. Temporary structures shall be maintained to prevent unnecessary erosion and other non-point sources of pollution.

Within 30 calendar days of when no longer being needed, these features shall be completely removed. Revetment that has been removed may be incorporated elsewhere in the project provided it meets the specification for the intended final use. All other fill material shall be removed to an upland area. All disturbed areas shall be reshaped and stabilized.

2547.04 METHOD OF MEASUREMENT.
Temporary stream access will not be measured separately but will be considered as a lump sum.

2547.05 BASIS OF PAYMENT.
For Temporary Stream Access, the Contractor will be paid the lump sum contract price. This payment shall be considered full compensation for furnishing all material, labor, and equipment and for the performance of all work necessary for the construction, maintenance, use and removal of temporary stream access, reshaping, and stabilizing; all in accordance with the contract documents.

Temporary stream accesses installed by the Contractor but not included in the contract documents for payment shall be considered incidental to Mobilization.

Seventy-five percent of the lump sum contract price will be paid when the Contractor has installed the Temporary Stream Access. The remaining 25% will be paid when the Temporary Stream Access has been removed, and the area reshaped and stabilized.
