Project Considerations

  • Original construction drawings that identify the structural form of the building.
  • Details of the nature of the frame, including special forms of construction –e.g. cantilevered elements, pre-stressed, pre/post tension elements, type of roof and other structural systems.
  • How structural stability is maintained – e.g. shear walls, braced bays, shear cores.
  • Structural defects or major alterations / additions to original construction
  • Services information- e.g. Underground cables, overhead lines, meters, gas mains, fuel lines, telecommunications, radio & TV, ancillary equipment and transformer rooms.
  • Previous use e.g.- existing hazards, ordnance, contamination, voids, cellars, culverts, underpasses, equipment decommissioning and asbestos -(asbestos removal)
  • Environmental issues e.g. – specific environmental requirements, watercourses, ecology, protection of flora and fauna, noise, waste disposal, adjoining / adjacent properties, archaeological.
