<p>please find below the quotation to carry out the feasibility&nbsp;review to the current VAV systems on the 6th, 7th and 8th floor vav systems.&nbsp;</p><p><strong>Feasibility&nbsp;Review</strong>&nbsp;</p><p>This stage will comprise a review of the recent VAV validation and some survey work to try and ascertain the operating characteristics of the installed systems serving each of the three floors (6th, 7th &amp; 8th). &nbsp;The success or otherwise of this exercise will depend on the ability to establish the original design criteria and the commissioning data for the system. &nbsp; We would also propose to input the existing building layout and the&nbsp;Crossrail&nbsp;layouts for each of the three floors into our thermal&nbsp;modelling&nbsp;software to establish the cooling and the ventilation loads that the air conditioning system is trying to address. The review will therefore seek to compare what we believe the existing system is capable of and comparing this with the loads imposed by&nbsp;Crossrail, as&nbsp;modelled. &nbsp;The extent of the discrepancy will determine the scope of works which remains unknown until this initial phase is undertaken.</p><p>In order to prepare the&nbsp;modeling&nbsp;we will need&nbsp;Autocad&nbsp;(.dwg) layouts of the 6th, 7th and 8th Floors (from BSD). &nbsp; The findings of the review and the results produced by the model will be presented at a meeting to Engie where solutions will be discussed and agreed and costs to&nbsp;be produced.</p><p>The timescale to complete stage 1 is 3 weeks ( works program&nbsp;to be issued along side the quotation).</p><p><strong>Our Total cost to carry out the above works for stage 1 only out of normal working hours shall be &pound;17,955.00+VAT</strong></p><p><strong>&nbsp;BREAKDOWN</strong></p><p>&nbsp;Design specialist costs - &pound;13,455.00+VAT</p><p>Site assistance for surveys - &pound;3,600.00+VAT</p><p>Site protection - &pound;300.00+VAT</p><p>Access equipment -&pound;600.00+VAT</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
