Unit content

1 Understand the techniques used in site investigation and evaluation Site investigation and evaluation: survey of existing buildings and building services,

topography of site; access to site; location of water table; nature, thickness and inclination of subsoil strata; classification of soils and sub-soils; testing of soils eg density, moisture content, void ratio, degree of saturation, permeability, porosity, shear strength, liquid limit, chemical nature; environmental issues associated with contaminated land

2 Understand how the techniques used in site investigation and evaluation influence the type of substructure

Type of substructure: characteristics of substructure; types of foundation; functions of substructure and foundations

Design of substructure: factors that influence selection of foundations; building control and regulations; structural considerations; soil type, effect of water and chemicals in soils; need for temporary and permanent dewatering; classification and characteristics of soils; issue of contaminated land; excavation techniques; disposal of soil; materials; sizing

3 Understand the types of superstructure design and construction

Types of superstructure: walls; roofs; structural frames; claddings; finishes; services Walls and roofs: domestic, industrial and commercial; external and internal walls; flat and pitched roof construction and coverings; medium and long span construction techniques Structural frames: selection and types eg steel, concrete, timber, laminated timber Claddings: steel; plastic; concrete; glass; industrial and commercial roof construction and coverings; insulation; fire protection; issues of corrosion; protection from corrosion Finishes and services: internal and external joinery and ironmongery; internal structures; internal finishes; simple primary services design and installation

4 Understand the causes of decay and deterioration of buildings

Decay and deterioration of buildings: causative factors eg human, chemical, biological, atmospheric, structural, thermal movement, moisture movement, fire, vandalism Maintenance: routine maintenance works and adaptation works; conservation of scarce materials; routine cleaning; cyclical and preventative maintenance; cause and effect of dilapidations

Common faults: poor or inappropriate design; poor workmanship; inappropriate selection and use of materials and systems

Essential requirements

Consideration must be given to sustainable methods of construction and environmental issues when selecting and using materials. Construction methods and practices must comply with health, safety and welfare legislation and practice. Particular attention must also be given to the implications that site investigation and design of buildings has on their safe construction, use and maintenance. The Construction (Design and Management) Regulations 2007 Safety Plans are important in linking design and building aspects in order to avoid risk.

It is essential that a culture of health and safety is embedded in all the units to ensure that the learners understand the importance and relevance of health and safety issues. Therefore there should be clearly signposted aspects of current legislation and health, safety and welfare implications throughout the delivery and assessment of this unit.

Employer engagement and vocational contexts

Tutors should organise site visits as part of delivery for this unit. To ensure site visits are successful tutors should outline the aims and objectives of the visits, conduct preparatory briefings and encourage learners to review the site visits once completed. Tutors should organise presentations by visiting speakers, for example building surveyors and/or designers on how to design out potential building defects. Tutors should use real-life case studies, for example superstructures for multi-storey buildings, and/or practical building surveys with maintenance recommendations.
