Disgrifiad o'r contract
We are inviting tenders to appoint a main contractor to carry out the following works at our Wrexham office:
• Rectification of the loft insulation to a continuous, uninterrupted depth of at least 200mm throughout the building, a further 100mm of mineral wool should be laid perpendicular to the existing to give a total depth of 300mm. attention should be given to joining the loft insulation with wall insulation installed, to form a continuous insulated envelope, as part of any future retrofit design. Access throughout the loft space should be enabled and any missing sections of loft insulation should be rectified. Note that all mineral wool should be installed beneath the existing electrical cables so any heat can dissipate into the loft space. The clear airflow pathways into the loft space at the eaves should be maintained to prevent moisture affecting the roof timbers
• Installation of a full mechanical ventilation with heat recovery (MVHR) system installed above the suspended ceiling on each storey prior to installation of window replacement.
• Replacement of current windows and external doors with energy efficient higher g value glazing windows throughout the building .
• Existing gas heating system to be replaced with an all-electric heat pump system. This would effectively mean expanding the current strategy of using split unit air conditioning for cooling, using reversible heat pumps to provide adequate heating.
• Replacement of water heaters in the kitchen and wcs
• A full MCS compliant solar PV system
. No claims from the contractor for additional payment will be allowed on the grounds of any misunderstanding in respect of matters arising from failure to evaluate local conditions. The price offered by the Applicant will be firm and fixed for the duration of the contract.
