Guidance for Manhole Rehabilitation in Army Underground Heat Distribution Systems
Abstract
Field inspections at many military installations have shown that deterioration of components in manholes is one of the main reasons for loss of efficiency and lowered service life of underground heat distribution systems. Periodic inspections and repairs are therefore considered essential for ensuring reliable, economic system operation. However, no guidance has previously been available specifically addressing manhole inspection and remedial action. To provide this guidance, the U.S. Army Construction Engineering Research Laboratory (USACERL) has developed step-by-step instructions intended to help facilities engineers perform effective inspections and determine what repair work should be scheduled. Information includes guidance for conducting a typical inspection, with a standard checklist provided for field use; sampling procedures required to meet current regulations when asbestos-bearing insulation may be present; and for preparing contract documents to procure the repair work.
