Several housing communities administered by RRHA are served by gas utilities for heating and cooking purposes. Government laws and codes (CFR 49 Part 192, AMPP SP0169- 2013, ASME Standard B31.8) require periodic surveys of any gas supply lines for leak detection and underground lines for cathodic protection. RRHA is responsible for ensuring that these inspections are conducted on underground piping systems from the City of Richmond Public Utilities Department installed master meter to the individual buildings. The housing communities served by natural gas include: Gilpin Court - Galvanic anodes • VA 7-1 25 buildings • VA 7-2 29 buildings • VA 7-9 46 buildings Mosby Court North - impressed current • VA 7-8 14 buildings Mosby Court Central - impressed current • VA-7 52 buildings with 168 gas services Gilpin Court consists of 100 buildings with two master meters as noted approximately on the drawings. The gas piping runs underground between buildings and then through each building’s crawl space. The Mosby Court community is divided into Mosby North and Mosby Central with each community having a single master meter. All gas piping is underground from the master meter to each building unit. The Gilpin drawings show existing gas piping as determined during a 1982 inspection and renewal of lines. The Mosby drawings show only general arrangement of the lines as originally constructed. In both drawing sets, the master meter location is approximate in relation to the buildings. • The contractor shall provide all equipment and personnel necessary to conduct the cathodic protection inspections services and leak detection services in accordance with industry standards and applicable government rules and regulations as previously noted. RRHA will provide escorts while conducting inspections. • At the completion of the services, the Contractor shall provide CHA with the original reports of the inspections conducted. The contractor shall also provide a cost estimate for any recommended repairs.
