<p><strong>R</strong><strong>e</strong><strong> </strong><strong>IRC Heathrow - Fire Door Surveys</strong></p><p><strong>&nbsp;</strong>Further to our recent meeting on site at IRC Heathrow, I now respond as requested with our proposed terms of reference and fee to undertake a detailed fire door review.</p><p>The fire door review will include Harmondsworth site phase 1 and phase 2 including the administration areas and Colnbrook site including the administration areas.</p><p>Having reviewed the fire strategy document produced by HLM Architects for phase 1 it appears that each individual bedroom is constructed as &lsquo;a single fire tight compartment&rsquo;, whereas the fire strategy drawings for phase 2 typically indicates only the stair cores are constructed as compartments, but not each individual bedrooms. It appears that the fire strategy for phase 2 has altered following a refurbishment around 2009.</p><p>Colnbrook appears to follow the same strategy as phase 1.</p><p><strong>Terms of Reference</strong></p><p><strong>&nbsp;GDC</strong>&nbsp;to undertake an assessment of each fire door as per the current fire strategy requirements, advise on whether the door is adequate to achieve the required fire rating and where necessary recommend remedial measures that will allow the door set to achieve the required performance on completion of upgrading works.</p><p>Please note assessments and recommendation will be made based upon the experience of our fire engineers / surveyors as well as published guidance documents.</p><p><strong>Strategy Review</strong></p><p>&bull; Review existing information and annotate drawings prior to attending site.</p><p>&bull; Review strategy plans and documents to confirm fire safety provisions.</p><p><strong>Colnbrook Fire Door Review</strong></p><p>&bull; Attend site and undertake a review of the fire doors across the building, in line with the fire strategy provided. (This does not allow for reduction of fire compartmentation as shown on Phase 2 area) &ndash; Circa 1500 doors</p><p>&bull; Production of spreadsheet outlining fire door issues and defects.</p><p><strong>Harmondsworth</strong><strong> Phase 1</strong></p><p><strong>&nbsp;</strong>&bull; Attend site and undertake a review of the fire doors across the building, in line with the fire strategy provided. (This does not allow for reduction of fire compartmentation as shown on Phase 2 area) &ndash; Circa 1000 doors</p><p>&bull; Production of spreadsheet outlining fire door issues and defects.</p><p>&nbsp;</p><p><strong>H</strong><strong>armondsworth</strong><strong> Phase 2&nbsp;</strong></p><p>&bull; Attend site and undertake a review of the fire doors across the building, in line with the Interserve fire strategy provided &ndash; Circa 50 doors</p><p>&bull; Production of spreadsheet outlining fire door issues and defects.</p><p>&nbsp;</p><p>Where possible the design fire rating of the door assembly will be identified through the door markings/plugs, where these are not evident the surveyor will base their assessment on relevant knowledge and experience. The assessment of the fire performance of an existing door will be made based upon previous experience of reviewing testing fire door assemblies and what are typical details common to most fire doors e.g. material and thickness of door leaf / frame / stops, type and number of hinges, glazing details including beading thickness and profiles, suitability of ironmongery and presence of intumescent strips or seals. Reference will also be made to relevant British Standards and other guidance documents such as BS 8214 &ndash; Code of practice for fire door assemblies.</p><p><strong>Fee</strong></p><p>In order to undertake the above, we propose:</p><p>Strategy Review <strong>&pound;1,599.00</strong></p><p>Colnbrook (including administration blocks) <strong>&pound;25,181.00</strong></p><p>Harmondsworth &ndash; Phase 1 (including administration blocks) <strong>&pound;17,329.00</strong></p><p>Harmondsworth &ndash; Phase 2 <strong>&pound;2,691.00</strong></p><p>The above costs include all travel time and disbursements, but are exclusive of VAT at the current rate.</p><p>Should at any time during the site surveys, our fire surveyors are required to leave site due to a disturbance, a full day or part thereof will be charged.</p><p>This fee is based on the information provided at enquiry stage.
