      Preliminary assessment indicates extremely weathered rock at approx 2-
      3m below general excavation levels, which will significantly reduce risk
      of slip, and provide massive horizontal restraint to retaining walls.

      The loose surface sands arc very prone to erosion and slippage,
      particularly where vegetation is removed or stormwater becomes
      concentrated.

3.4   Construction Management Plan

      The site is located at the northern end of a sealed access driveway off
      Seaview Tce, with no off-site parking and set down areas for construction
      equipment. The size of vehicles accessing the site is limited by the width
      and layout of the common driveway.

      The Contractor will face various challenges on this project due to the
      limited access, however it is clear that local Builders have had sufficient
      experience with these types of sites eg, at the adjacent homes in Seaview
      Tee; the recent construction of Pat Rafter's house at 48 Seaview Tee; and
      current construction along Park Rd, Noosa.

      We suggest that the site is sufficiently large to accommodate all
      construction vehicles and equipment/materials storage, providing the
      Contractor plans his work carefully, and builds staged temporary access
      ramp/platforms similar to our layout on 09578-P4.

      During the initial piling stage of the project there will be very few
      subcontractors (Piling Contractor and part-time Surveyor) on site and
      therefore "Stage 1 Temporary Access Area" of about 700m2 indicated on
      Drawing 09578-P4 should be adequate for all access, parking and storage.
      Total number of cars on site would be less than five.

      Once the contiguous piling is completed, screw piling will be completed
      over the site and again there would be few other Subcontractors involved
      in the works that time. (Piling Contractor and Part-time Surveyor)

      By this stage the Contractor should have extended his temporary
      access/parking/storage platform across to the northern area of the building,
      "Stage 2 Temporary Access Area" indicated on 09578 - P4, greatly
      increasing parking, access and storage for materials. Total number of cars
      on site would not exceed 10. During this time there would still only be
      about 4-5 different subcontractors on site:-

          •   Concretor/formworker
          •   Reinforcing fixing
          •   Plumber (part-time)
          •   Surveyor (part-time)

      By the time the builder is constructing the floor slabs, we would expect
      the number of subcontractors will increase up to approximately 10
      occasionally, but the accessible area for parking and storage will he
