COSVR699Carry out checks and record installation of works
Carry out checks and record installation of works
• why it is important to carry out specified checks of the retrofit works during installation and record the works conform to:
‐ quality
‐ standards
‐ manufacturers' instructions, technical information and product data sheets
‐ retrofit desigmn
• how to carry out checks and record installation of works for quality, standards and compliance with the retrofit design, and manufacturers' instructions, for the following:
‐ alterations to the structure
‐ loadings
‐ fixings
‐ corners, junctions and edges of building elements
‐ interfaces between the building fabric, services and the occupants
‐ windows and doors including reveals, sills and soffits
‐ thermal bypass
‐ thermal bridges
‐ air tightness
‐ vapour barriers
‐ moisture movement
‐ moisture ingress
‐ condensation and interstitial condensation risks
‐ rainwater goods
‐ mechanical, electrical and plumbing (MEP)
‐ fire safety
‐ acoustic and sound insulation
• the potential risks and implications of non-compliance and poor quality installations over time, for active and passive fire safety measures
• the potential risks and implications of non-compliance and poor quality installations over time, including but not limited to:
‐ occupant health and safety
‐ indoor air quality
‐ mould
‐ performance gaps
‐ rot
‐ building fabric decay
‐ overheating
• the importance of maintaining ventilation
• why it is important to recognise ventilation and air movement pathways through buildings and ensure that these are maintained, whilst balancing the need for airtightness
• the different properties of insulation materials and how these relate to thermal, moisture, condensation, acoustic and sound, and fire safety
• the different types of air and vapour control layers and breather membranes, where and how they should be used, and why it is important to install them correctly
• the importance of ensuring the integrity of air and vapour control layers and breather membranes following installation and the need to ensure continuity
• how condensation forms in buildings, how this relates to moisture and moisture movement and what steps can be taken to mitigate potential risks
• why a whole building approach is taken to retrofit works and how this relates to building performance and building use
