605.3CONSTRUCTION —Before construction or fabrication, obtain acceptance of shop drawings, if required.
as shown on the accepted shop drawings, and as follows:
• Cement Concrete Structures —As specified in Section 1001.3
Excavate for the structure as required. Place No. 2A Coarse Aggregate and compact as specified in Section 350.3(e), if specified. Place concrete foundations and walls monolithically, except if otherwise allowed. Carefully remove existing castings that are to be reused. Clean and transport to the new location. Construct new inlet or manhole walls and b ottoms to accommodate the dimensions of the existing castings. Set frames, concrete top units, and grade adjustment rings (if required for inlets and manholes) on a bed of non -shrink grout to provide full bearing on the supporting surface . Set pipes in inlets and manholes, flush with the inside structure face. For pipes protected by end walls, set flush with the exposed structure face. If constructing structures in conjunction with existing pipe culverts and drains, provide for satisfactory connections, as specified for new construction of a similar type. 605.3(a) 605.4(l) Section 206.3(b)4. Satisfactorily dispose of unsuitable and surplus materials. Brick and Brick and Mortar are not allowed for grade adjustments. Coat all aluminum surfaces to be embedded in concrete with one coat of zinc chromate primer, or a coat of asphalt paint. Allow to dry completely before placing concrete.
