Drainage Board at the time installation is completed and to any adjustments needed for field conditions that could not be anticipated on the design drawings. y
34. Contractor to record dimension of each water stub from nearest fire hydrant measured along the water main.
35. The above locations of laterals, along with any other construction changes are to be incorporated on the original construction drawings and record drawings submitted to
the Clay Township Regional Waste District Office as soon after completion of construction as possible.
36. Contractor shall verify subsurface conditions prior to bidding.
