The construction phase will always require detailed design. This should build on, rather than depart from the principles set out in the original planning application.
This stage in the project may require the undertaking of additional specific survey work to ascertain detail that would have been costly or inappropriate to carryout earlier when there was a risk that a development might not obtain planning permission. Such surveys are likely to focus on ground conditions and geotechnical analysis that feeds into the construction detail. A more limited analysis should have already been undertaken to establish development feasibility (and assumptions made on this). However a greater degree of detail is likely to be required to enable construction to take place e.g. nature and detail of foundation design.
This stage in the process requires the preparation of detailed architectural and engineering drawings of all elements of the proposed development. This will be a complex stage in the process and liaison between the architect and relevant engineers (for example, construction, process mechanical and electrical engineers) will be necessary to arrive at the desired outcome.
