Submit new inquiry for this projectInquiry #1: Drainage System 7-D GT4 DI is described of having a height of 3.1’ in the drainage quantities (sheet 172) but in the profiles (sheet 160) the difference between the Grate FL and the outlet pipe FL is 2.51’. If the inlet is 2.51’ between Grate FL and Outlet Pipe Opening, there is a conflict due to the minimum height of the GT4 Lid described in the 2023 Standard Plan D73D Section E-E. Can Caltrans consider changing this inlet into a G6 inlet? Please advise.
