This specification covers the design, testing, manufacture, selection, and installation of fabricated metal access hatches for utility, water, and wastewater structures including utility vaults, drainage structures, valve vaults, meter vaults, wet wells, pump enclosures, utility trenches, piping trenches, and drainage trenches. It applies to various configurations of access hatches constructed of fabricated metal of various materials and grades for various loading conditions, traffic speeds, or both. It provides engineering design and testing criteria for access hatches to be located in various areas subjected to various loading conditions, traffic speed, frequency, or combinations thereof. It also includes production loading criteria to allow the access hatches to be tested in order to verify the load capacity of the manufactured hatches, as well as hatch loading selection guidelines to allow selection of the proper hatch design loading for the conditions of the actual area of placement. This specification also details requirements with respect to the acceptability of the access hatches, material certification and quality control, repairs, inspection, marking, optional features as part of the access hatch design, and submittal drawings.
