Dredging Pay Quantity Surveys
We have significant experience monitoring dredging operations in river and harbor navigation projects. Our skilled hydrographers routinely perform project condition, pre dredge surveys, interim dredge surveys and final clearance and acceptance surveys as well as provide volume computations and final as-built survey drawings. Whether the contract calls for a licensed surveyor, an ACSM Hydrographic Surveyor, or both, we can provide your dredging support.
