general workplace activities, other occupations and adverse
weather conditions and how to minimise damage to existing
building fabric
Performance Criteria 5Meet the contract specificationK14. how the methods of work to meet the specification, are carried
out and how problems are identified and reported by the
application of knowledge for safe, healthy and environmental
work practices, procedures and skills relating to the method
and area of work
14.1 the suitability, compatibility and characteristics of the materials,
components and finishes, and determine if they are moisture
open or moisture closed, their impact on the building and
their appropriateness to the design and physical application
14.2 how to record and report issues or defects with the materials,
components and finishes
14.3 why it is important to carry out external and internal
pre-installation checks
14.4 how to carry out external and internal pre-installation checks,
assessing, recording and reporting issues to include but not
limited to:

  • property suitability
  • structural integrity
  • dampness
  • decay
  • exposure ratings
    - vents and ventilation
    - services (gas, electric, water, media cables)
    14.5 why it is important to ensure that all necessary repairs are
    completed prior to installation
    14.6 the implications that types of construction and materials have
    on the introduction of energy efficiency measures and other
    forms of building treatments with specific reference to:       - roofs       - walls including internal and external finishes       - floors       - windows and doors       - chimneys and fireplaces       - flues and combustion ventilation       - fabric interfaces       - existing services
    14.7 the importance of the correct sequencing of installation of
    energy efficiency measures and building treatments
    14.8 how performance varies in different construction types,
    locations and through the impact of habitation and usage

    limited to: salt contamination and causes of dampness, rain
    penetration, rising damp, internal moisture vapour, damaged
    services, structural defects and understand the implications of
    these when they are present
    14.11 how achieving continuity of the insulation and building
    treatments can prevent problems such as water ingress, poor
    energy efficiency and thermal bridges, whilst understanding
    the unique circumstances at party walls and the associated
    risks to adjacent properties
    14.12 how to recognise unintended consequences, why they
    happen, how to avoid them and the importance of moisture
    content in external fabric including but not limited to:          - impacts on neighbouring properties          - insulation fitting and placement for different insulation
    types          - junctions          - thermal bridging and condensation risks          - thermal bypassing          - void ventilation

    and the impact of ventilation and air flow following the
    installation of thermal efficiency measures
    14.14 the implications of building defects and the repairs required
    and how they will affect the choice of energy efficiency
    measures and building treatments
    14.15 the importance of compatibility and interactions between
    measures and the fabric of the underlying building
