To start a building project you need to provide a site. Today's environmental requirements are such that one of the first engineering considerations is storm water control. Most municipalities require engineered storm water drainage studies and the possible need for detention or retention structures.
After providing a site then a foundation is required. Knowledge of geotechnical parameters must be interpreted to determine the best foundation design for the proposed building. Note that the "minimum" acceptable foundation as detailed in building codes may well be inadequate for the actual soil conditions present; your structure is only as stable as your foundation.
Utilities to service your building may require extensive service extensions depending on your building site. Water or sewer extensions are often needed to serve your building and must be engineered for city or utility system approval. Modern construction permits most often require erosion and sediment control designs. The engineering and drafting of proposed erosion control designs will complete your submittal package to the Authority Having Jurisdiction.
