<p>Our total cost to carry out the above works in / out of normal working hours shall be</p><p><strong>General Roof Condition</strong><br />This is a large roof area of some 10,300 m2, the roof is weathered with double skin profiled metal&nbsp;roofing sheets, the outer sheet has a protective plastisol coating to the weatherside.&nbsp;The roof is served by a perimeter metal eaves gutter and one central valley gutter.<br />There is a safety line mounted along both ridges.&nbsp;Our inspection was limited to the central valley section of the roof, which was safe to traffic.&nbsp;The valley gutter had a build-up of debris, this was collecting around leaf guards on all the outlets,&nbsp;partially blocking the drainage and allowing water to pond in some sections of the gutter.&nbsp;A number of gutter joints have been patched repaired with a coating&nbsp; compound, suggesting the&nbsp;gutters have caused problems in the past.&nbsp;We assume the perimeter gutters are in a similar condition, the gutters should be cleared to ensure&nbsp;they drain correctly, if one or more of the outlets becomes badly blocked it could cause significant<br />problems during heavy rain.&nbsp;The protective colour coating is peeling away from the end laps on all the roof sheets, exposing the&nbsp;steel core and leaving it vulnerable to both top side and reverse side corrosion, overlaps especially&nbsp;can be affected as harmful pollutants held in capillary drawn rainwater can attack the steel and&nbsp;reduce the useful life of the roof.</p><p><strong>There are 3 No leaks:&nbsp;</strong><br /><strong>Valley Gutter / Zone S</strong><br />Leaking around rainwater outlet, although dripping at the time of our visit, we were unable to&nbsp;determine if the outlet seal at roof level is defective or if there is a problem with a joint of the&nbsp;internal downpipes, (siphonic system).</p><p><strong>Below the Eaves Gutter in the North West Corner of Warehouse:</strong><br />There is an outlet located directly above this area, this was not leaking during our visit, either the&nbsp;seal around the outlet has failed, one or more of the gutter joints in this area has failed, or, like the&nbsp;valley gutter problem described above, there could be a problem with a joint in the downpipe.</p><p><br /><strong>Eaves Gutter - Jim&rsquo;s Office:</strong><br />There are staining ceiling tiles along the far wall of the office suggesting there is a problem with the&nbsp;gutter or perimeter capping, at roof level there was evidence of patch repairs to the gutter joints&nbsp;and the perimeter capping detail.&nbsp;Bearing the above points in mind, we would suggest the following course of action.</p><p><strong>Specification - Minor Repairs:</strong><br />To have two roofing operatives attend site for one day, clear the water and debris along the gutter&nbsp;sections above the three locations.<br />Remove any loose sealants from the suspect outlets and nearby gutter joints and apply Signature&nbsp;PU Liquid Fibre, a high&nbsp; performance coating compound.&nbsp;This coating is single component, polyurethane (PU) fibre reinforced, liquid membrane.&nbsp;To check the joints in the cappings and associated flashings, carry out suitable repairs to any&nbsp;defects found.&nbsp;To carry out the works safely our operatives would wear safety harnesses connected via lanyard&nbsp;and adjustable rope (providing a travel restraint), to the existing roof mounted safety line, we would&nbsp;need to see the current certificate for this safety line.</p><p><br /><strong>Total Cost: &pound;1,375.50</strong><br />If the repairs to the outlets fail to solve the problems then you would need to have the internal&nbsp;siphonic drainage inspected / tested, a MEWP would be required for access.</p><p><strong>Specification:&nbsp;</strong><br />To clear the existing gutters of debris to normal industrial standards, some 465 linear metres, bag&nbsp;up and lower the debris to ground and remove from site, provide before and after photographs for&nbsp;your records.&nbsp;The works would be carried out using safety harness, lanyard, rope to provide a travel restraint.&nbsp;We would provide a suitable MEWP to remove the bagged up debris to ground level, which we can also use for personnel access.</p><p><strong>Total Cost: &pound;3,243.75</strong></p><p>Please Note: We were only able to inspect the valley gutter safely, we have therefore assumed&nbsp;that the perimeter gutters are in a similar condition, if there is a larger build-up of debris then&nbsp;additional time on site maybe required, if your client wished to proceed with the repair works we&nbsp;could inspect all the gutters safely, as we would have harness and lanyards on site, and advise on&nbsp;there condition.</p><p><strong>Roof Sheeting</strong><br />During our visit we noted the poor condition of the end laps of the roof sheets, for your information&nbsp;we provide a data sheet on Girosil Edge, a treatment specifically designed for this problem.&nbsp;From Goggle Earth we estimate that there is some 2300 l/m of laps to treat, to prepare and apply&nbsp;the Giosil system, providing a MEWP for access and as part fo the Rescue Plan.</p><p><br /><strong>Budget Cost: &pound;55,000.00 - &pound;60,000.00</strong><br />We can arrange for Messrs Girosil to carry out and inspection and provide a report if this is of any&nbsp;interest, we would also need to discuss Health and Safety arrangements for the project.</p>
