08/14/2025 ENGR - Drainage Structures Partial Pass 8/14/25 partial pass to backfill pipe.

8/14/25
I looked at 18" Drain pipe bedded between 3 Catch Basins at NW of site.
Pipe is bedded correctly and is in line with survey nails for placement. Okay to backfill.

Holes are dug for Catch Basins but 4 cft Gravel drain underneath CB not centered correctly as shown in plan. Contractor will remove gravel where needed and center it correctly. Gravel will be replaced with fill and compacted with machine. Forms at bottom of Cb will be moved out 3" to increase bearing surface of slab 6" each way. I will check gravel/forms tomorrow when looking at reinforcing for CB's
