<p>Thank you for inviting us to forward our survey observations along with our specification and quotation for the roof remedial works for 2no locations at&nbsp;&nbsp;the above stated premises.</p><p>It was reported whilst on site that the flat roof installation was undertaken by a different contractor approximately&nbsp;four years ago. It appears the the staff room below is subject to water leaks from above. As a result of this observation we proceeded to perform a core cut in order to identify the condition of the roof fabric below the felt.&nbsp;</p><p>Upon carrying out the our core cut, we have found that the roof had only been lined with one layer of very thin felt. We normally advise for the felt to be built up in three layers. Further to this we have found the vapor&nbsp;barrier located under the surface felt and above the insulation board. This is an inefficient design and is not fit for purpose since the vapor barrier is typically situated in between the asphalt and insulation board.</p><p>Further to this the main water outlet was found to have no insulation present. The only roof coverings for both outlets are asphalt and felt.&nbsp;</p><p>As a result of our observations&nbsp;please see below our remedial scope of works:&nbsp;</p><p><strong>Site Set up:&nbsp;</strong></p><p>GDC operatives to attend site during working hours.</p><p>To ensure all works are carried out in a safe manner and in accordance with RAMS.</p><p>To arrange delivery of 8yard site skip.
