Technical Description- Pit Plan.jpg

This is an architectural/engineering drawing depicting a pit plan for what appears to be a containment or control facility. The drawing is scaled at 1/2" = 1'-0" and shows a detailed layout of a non-control pit measuring 12'-8" by 10'-8" with a control pit section. The plan includes two ladder bolt access points with a slope to trench ratio of 1/8" per 1'-0", a centerline hatch sheave measuring 4'-8 1/4" in width, and a control pit hatch measuring 4'-9 1/2" with a clearance height of 8 1/2". A sump area is incorporated with a 3" diameter pipe sleeve for sump pump discharge, and the sump trough is detailed in Section E-E. The design specifies a 2"-high concrete pad and includes a deflector sheave with a 1'-9" dimension and a 1'-0" clearance measurement. Grade slopes are specified at 1/8" per 1'-0" from the trench. A note indicates that the contractor must verify the anchor bolt pattern of new braking assembly. The overall pit configuration includes provisions for antenna control and non-control pit functions with multiple dimensional callouts for structural and functional elements.
