<p><u><strong>Scaffolding</strong></u></p>

<p>To erect scaffolding to form an independent scaffold to access valley roof area. Tower scaffold erected bridged/over door. To erect independent scaffold to access flat roof.&nbsp;</p>

<p><u><strong>Corridor.</strong></u></p>

<p>This is narrow Zinc roof, stepped with rolls, plastic PVC cladding either side of the zinc covers the&nbsp;upstands, there are two small a/c units sited on the roof.&nbsp;The roof has been subject to a number of minor repairs, a bituminous coating has been applied&nbsp;over some of the sheets, this seems a pointless repair as it would achieve nothing, Flashband tape&nbsp;has been applied to the right hand side upstand and over the zinc rolls.&nbsp;The current leaks correspond with the right hand upstand detail / Flashband repairs.&nbsp;Given the age of the roof and extent of the repairs, further repairs are unlikely to provide a long&nbsp;term solution, we would therefore suggest it is completely upgraded.<br />
The main problem is that we cannot achieve an adequate seal to the existing PVC cladding and&nbsp;we have to assume it is secured to timber supports, the positioning of the small windows further&nbsp;hinders us, although these appear to be redundant.</p>

<ul>
	<li>Operatives to apply protective sheeting to work routes and working areas.</li>
	<li>The existing A/C units and pipework will need to be temporarily removed by others to facilitate the new corridor roof install.&nbsp;</li>
	<li>To remove all old flashband tape, cut zinc as needed to locate the supports, notch across the zinc rolls at these points and cut off the overhangs along the steps to leave a resonable level surface.&nbsp;</li>
	<li>Supply &amp; install&nbsp;counter battens across the width of the roof (fixing where the rolls are notched).</li>
	<li>Mechincally fix an 18mm plywood sheet into the counter battens, (over the flat roof area).&nbsp;</li>
	<li>To supply &amp; install 12mm plywood over the vertcal PVC cladding to form new upstands, taking over the small windows that appear redundant, finishing tightly to the underside of the soffit.&nbsp;</li>
	<li>Supply &amp; install angle fillets to the base of all upstands and the steps in the roof.&nbsp;</li>
	<li>Supply &amp; lay over this new surface a two layer and a 4.5mm thick Testudo Flexter cap sheet, with a mineral surface finish to the weatherside.&nbsp;</li>
	<li>Forming all upstands and associated roofings details to complete the new roof.&nbsp;</li>
	<li>Supply &amp; install termination bars along the top of the new ply upstands, secured tightly to the underside of the soffit.&nbsp;</li>
	<li>All waste to be disposed of.&nbsp;</li>
	<li>Site to be left clean and tidy.</li>

<p><b><u>Hall</u></b></p>

<p>Leaks have been an ongoing issues and some repairs have already been undertaken. This is a felt roof, it is evident from the condition of the existing cap sheet that this roof is nearing the end of its useful life. The mineral finish (chippings) that protect the felt are delaminating, exposing it to harmful UV. Rays, there is evidence of shrinkage, a few air blisters and the laps on some of the detailing are&nbsp;starting to lift.<br />
However, only one leak was evident during our visit, but we were advised of one other sporadic&nbsp;leak in the general area (above the wall mounted phone).&nbsp;Upon inspection we found that the previous repairs were poorly undertaken, its seems that the&nbsp;lead coverflashing was stolen from the underside of the overlooking glazing, it was poorly repaired&nbsp;with a felt upstand that is short of the underside of the window cill, leaving the timber framework&nbsp;exposed and the detail vulnerable to driving rain.&nbsp;We cannot be certain that this is the cause of the issues, but until it rectified it would seem futile&nbsp;looking further afield.</p>

	<li>Operatives to apply protective sheeting to work routes and working areas.</li>
	<li>To supply &amp; install new felt upstands where the existing are too low and the timber frame is exposed.&nbsp;</li>
	<li>To mechanically fix a new GRP termination bar along the full length of the underside of the window cill.&nbsp;</li>
	<li>To patch over defective laps in the local area above the reported leaks.&nbsp;</li>
	<li>Site to be left clean and tidy.</li>
