Answer 8

Their objective is to collect and record data to help with the design and construction process. This should include matters in relation to the site that may impact the development e.g.
- Boundary hedges & fencing
- Existing trees
- Size, depth and location of services including gas, telephone, electricity, water & drains
- Existing buildings
- Ground water conditions
- Soil investigations
- Trial pit information

Question 9

What is the purpose of soil investigations?

Answer 9

• Their purpose is to determine the suitability of the site for the proposed works and determine adequate and economic foundation design
• The investigation should determine the potential difficulties associated with the ground conditions and assist with identifying a suitable foundation solution
