The scope of work for the contract will include, but is not limited to, the following: • The Contractor will plant cultch in specified areas which will be designated by MDMR personnel in advance of the day of the cultch deployment. The contractor will give the MDMR Project Manager at least twenty-four (24) hours’ notice of cultch deployment. • Types of approved cultch material are course aggregate (#4 stone) or oyster shell. • Cultch will be clean and free of any hazardous substances or excessive dust. • Bidders proposing any non-domestic or non-traditional cultch material must include a marked 5-gallon representative sample of the cultch material at the time of the bid submittal. This sample will be used to determine the cultch material’s suitability for the project purpose. • The Contractor will guarantee that all cultch is clean and no more than 5% of the cultch material, by volume, may consist of fragments, pieces, fines, or shells smaller than ¾” to 1 ½” (three-fourths inch to one and one-half inch) in diameter. For cultch material other than shell, the size should be in accordance with the American Society for Testing and Materials (“ASTM”) C33 specifications, size #4 stone or equivalent, with no more than 5% by volume of the cultch material out of the ASTM size #4 stone specification. The MDMR reserves the right to have its representatives inspect all cultch material at the loading site before cultch material is accepted and each barge-load will be monitored at the deployment site. All small particles in excess of the allowed 5%, or otherwise outside of the specifications listed above, will be deducted from the total project cost.
