Design for compliance and construction
If the design and scale are within council guidelines then we can progress to this stage before planning approval is given. LTA will be able to advise on the extent of risk in doing this and you will know how tight your timescales are.
The 1:100 scale drawings submitted for planning are now developed to more detailed general arrangement drawings at 1:50 scale. Building services will be considered such as heating, plumbing and drainage. A structural engineer will be brought on board to provide design and calculations. Construction build-ups and insulation of floors, walls and roofs will be decided.
Outline specifications for each element of construction will be produced and detailing of major or unusual junctions will be drawn up.
