<p>Description</p><p>Replacement of leaking water main (leaking section only). We have traced leak to inside boundary fence on previous investigations. Please note we have also found damaged drainage allowing leaking water main to escape. This will be in proposed works below to repair.</p><p>Proposed Works</p><p>&bull; Scan area with using cable avoidance tools to ensure floor is safe excavate.</p><p>&bull; Set up approximately 12 metres of barriers to separate area from staff or site visitors.</p><p>&bull; Once area is safe to work remove top layer of shingle.</p><p>&bull; Once safe, start excavating approximately 3 metres at a depth of 1.2 metres. Please note this will be done by hand excavation only. We will also be shoring sides due to ground conditions.</p><p>&bull; Set up sump pump, preventing hole from flooding with fresh water.</p><p>&bull; Once pipework exposed replace damaged section in poly pipe using any fittings required (unable to determine until exposed)</p><p>&bull; Once repaired carry out pressure test on new pipework.</p><p>&bull; If pressure test in successful cover pipe in soft sand protecting from sharp objects and back fill hole with the soil removed.<!--[if gte vml 1]><o:wrapblock><v:shapetype<br ></v:shapetype><br /><br /><br /><br /><br /><br /><br /><br />
