Timing of Construction <br />Construction of the new federal courthouse would be phased to allow for investigation and <br />abatement of hazardous materials, demolition of existing buildings and parking lots, <br />archaeological surveys and recording of any artifacts found, and consultation with the state <br />historic preservation officer regarding impacts on historic structures, as needed. Site preparation <br />and substructure work would begin in early 2002 and would require approximately 6 months. <br />Building construction would require approximately 24 months, with occupancy estimated to <br />occur in early 2004. <br />I <br />New Federal Courthouse 37 Final ElS <br />
