071203 — Borrow Excavation

203.01 Description

Furnish, excavate, haul, and place approved materials for embankments and backfills when sufficient quantities of suitable materials are not available from other excavations specified in the Contract Documents. This includes all work prescribed for backfills, embankments, subgrade, and earth shoulders, all necessary clearing and grubbing, the removal and disposal of overburden or other unsuitable spoil material, and the trimming, shaping, dressing, draining, and reclamation of the pit or location from which borrow material is secured. Refer to 201.03.02 before securing borrow.

203.01.01 Contractor's Options. As a duly authorized agent of the Administration, select one

of the following three methods to obtain borrow material for use on public highway contracts: OPTION 1 - Acquire material from a licensed commercial operating supplier. OPTION 2 - Make application to the Maryland Department of the Environment under the Annotated Code of Maryland, Environment, Title 15, Subtitle 8, entitled "Surface Mining". OPTION 3 - Make application to the Administration to operate under the standard adopted in conformance with the Annotated Code of Maryland, Environment, Title 15, Subtitle 8, Surface Mining, Subsection 15-834 entitled "Exemptions." If this option is selected, submit an application to the Administration fulfilling all the requirements of the cited subtitle. Provide notification of the option selected to the Administration.

203.01.02 Notice to Contractor—Borrow Pits. If proposed, a borrow pit may be established on

privately owned property. The Administration may grant an "Exemption for a Surface Mining Permit" normally issued by the Maryland Department of the Environment, Water Management Administration (WMA). Before a permit can be granted, submit written proof to the Administration that all local permits or approvals have been secured for the borrow pits. An exemption under Option 3 will require approval of an excavation and reclamation plan along with the drainage patterns and methods of attaining satisfactory drainage and soil conservation as the work progresses. The plan shall provide for surface restoration suitable for the proposed subsequent land use after reclamation is completed and the proposed method of accomplishment. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS

203.01.03 Borrow Pits Within Jurisdictional Resources. Borrow pits located within tidal or

nontidal wetlands, waterways, and 100 year floodplains require approval by the appropriate Federal and State Authorities. Obtain and provide all required permits. If the pit is in operation and the Administration discovers that the work does not meet these regulations, the Administration will notify the contractor to make the necessary corrections, and all other operations shall cease until the work is in compliance.

203.02 Materials

Refer to Section 916.

203.03 Construction

203.03.01 Clearing and Grubbing. Refer to Section 101.

203.03.02 Borrow Pit Material. Notify the Engineer at least 30 days in advance of the opening

of any borrow pit so that soil analysis, elevations, and measurements of the ground may be made. After the pit is opened, use the excavated material only for the project intended. Do not excavate additional material for other purposes until a final survey is made of the pit.

203.03.03 Borrow Pit After Excavation. Meet the requirements of the Reclamation (Permit)

Plan after the necessary quantity of materials has been removed. Avoid steep slopes and sheer faces. Seed and mulch all disturbed areas as specified in Section 705, at no additional cost to the Administration. Shaping and seeding requirements do not apply to commercial borrow pits.

203.03.04 Borrow Excavation Beyond Specified Limits. Refer to 201.03.08.

203.03.05 Compaction. Refer to 204.03.04.

203.04 Measurement and Payment

Borrow excavation will be measured and paid for at the Contract unit price per cubic yard for the pertinent Borrow item. The payment will be full compensation for clearing and grubbing, furnishing, excavating and hauling, sloping, draining and reclamation of pits (if Option 2 or 3 is selected), the formation and compaction of embankments, backfills, subgrade, manipulation and additives for select borrow, all work and materials for earth shoulders except as otherwise specified, disposing of all unsuitable spoil material, and for all material, labor, equipment, tools, and incidentals necessary to complete the work. When requested by the Contractor in writing, the Engineer may approve an alternate method of measurement for the computation of borrow excavation quantities. This alternate method will not be considered for approval unless the Contractor can show that the cross section method computed by average end area is not a feasible method of measurement. When approved in writing, this alternate method will consist of measuring the borrow excavation in approved hauling vehicles. Refer to TC-7.01 and the following: 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS

204.01 Description

Construct embankment and subgrade using suitable material obtained from roadway, structure, borrow, and other excavation included in the Contract. Place, process, and compact material to the specified line and grade.

204.02 Materials

Unless otherwise specified, use soils and soil aggregate mixtures that meet the common borrow requirements specified in Section 916.

204.02.01 Rock. Rock may be used in embankments, if individual pieces do not exceed 24 in. in

any dimension. Larger size rocks may be wasted with the approval of the Engineer. 204.02.02 Frozen Material. Refer to 201.03.05. In addition, do not cover any material that freezes after being placed in the embankment until it has thawed. 204.02.03 Embankment Adjacent to Structures. The Engineer may require the use of specially selected material adjacent to structures to protect the structure from damage. Do not use rock. At locations of pile supported foundations, use embankment material that will allow piles to be easily driven.

204.02.04 Geotextile Inclusions. Refer to 919.01 Class SD Type II Non-Woven.
