<p><u><strong>Walkways</strong></u></p>

<p>The specification calls for rubber walkways tiles or similar.&nbsp;We are reluctant to use walkway tiles in this instance, typically they will only withstand gusts of up to 60 miles an hour unsecured, so they would require adhering.&nbsp;But that requires an adhesive compatible with both the existing single ply membrane and the new tiles, otherwise a chemical reaction may damage the roof membrane. We are confident&nbsp;that the existing membrane is Sarnafil but without O &amp; M&rsquo;s confirming this and the need to expedite the quote we&nbsp;have opted for a coating system.&nbsp;</p>

<p>The other concern is the condition of the existing membrane underneath the walkways, its badly discoloured and although no water ingress is reported, its possible that the membrane has some damage, any possible issues of this nature would be solved by using a coating system.</p>

<ul>
	<li>Operatives to apply protective sheeting to work routes and working areas.</li>
	<li>To remove and dispose of the existing loose laid walkways by mean of MEWP, this together with a skip for the debris would be sited in the courtyard.&nbsp;</li>
	<li>To erect heras fencing around MEWP and skip with suitable signage.&nbsp;</li>
	<li>To clean and prepare the existing singlw ply membrane.&nbsp;</li>
	<li>To apply Elastadeck Grit coat (black) at the rate of 1.25 litre per sqm, whilst wet insert elastadeck matting and white Aluminium Oxide Grits (30 mes) laid at the rate 1kg per sqm.&nbsp;</li>
	<li>Allow to cure.&nbsp;</li>
	<li>To apply Elastadeck sealer coat (graphite gey) at the rate of 4 litres per sqm.&nbsp;</li>
	<li>The new coating system would be applied to an overall run of approcximately 228 linear metres by 1100mm wide (existing is approximately 1070mm).&nbsp;</li>
	<li>All rubbish to be removed from site.&nbsp;</li>
	<li>Site to be left clean and tidy.</li>
</ul>

<p><strong><u>Gutters</u></strong></p>

<p>Clean out the existing perimeter eaves gutters around the building and the courtyard using a high reach vacuum some 460 linear metres in all.&nbsp;</p>

<p>Rake out the old mastic sealant as far as practical, throughly dry and prepare each joint then install&nbsp;HD Sharmans Seamsil Sealant, gun-applied into each joint, forming a complete bridge seal and&nbsp;tool off to a neat edge. Whilst the Seamsil is still wet, apply Seamsil Base Coat by brush to achieve&nbsp;a miniumum wet film thickness of 220mm, the Base Coat will extend a miniumum of 25mm either&nbsp;side of the gutter joint and a further 10mm beyound the prepared area, ensuring the complete&nbsp;coverage of all exposed steel work and gutter joint bolts.</p>

<p>Delcote GS system has excellent elastic properties to withstand normal surface movements&nbsp;associated with gutters and is unaffected by UV or extremes of weather and temperature.&nbsp;All outlets will also be cleaned, prepared and treated with this system.&nbsp;The works would be carried out using a suitable MEWP, this will require the phased cordoning off&nbsp;of the car park spaces around the building and pedestrian walkways, sections above doorways or&nbsp;busy areas can be carried out over weekends.&nbsp;We would expect to complete one elevation every two days, inclement weather may extend this as&nbsp;the gutters will have to be dried again.</p>
