<p>Upon our attendance and inspection of the ceiling void. We have identified condensation build up on the ductwork running throughout the entire span of the building feeding the air conditioning vents. &nbsp;</p><p>As a results of our appraisal we can conclude that the leaks are caused by condensation wherein the cold air inside the duct reacts with the warmer air outside the duct. Furthermore we have identified&nbsp;hairline cracks in the ductwork where it allows an accentuated amount of colder air to escape therefore accentuates the amount of condensation built up.&nbsp;</p><p>The remedial works required to alleviate this issue include the following:</p><ul><li>Expose all ducting.</li><li>Grind flat all corrosion spots and fill exposed cracks.</li><li>Paint all ducting in anti corrosion paint, 38lm in total with 4 coats.</li><li>Insulate with purposed made lagging in order to seal the ductwork from the environment.</li></ul><p>Our total cost to carry out the above works in&nbsp;normal working hours shall be: &pound;32,045.00</p><p>Breakdown:</p><p>Labour: &pound;3,445.00</p><p>Materials: &pound;5,054.00</p><p>Access Equipment: &pound;9,118.00</p><p>Duct Work insulation seal and test and pressure test: &pound;14,428.00</p>
