CONSTRUCTION PROCESS:
In-situ Concrete: All substructure walls and slabs were constructed using in-situ methods. Steel fabrication was carried out on site in correspondence with TGP drawings and schedules. Before any structure element was poured pre-pour control check had to be completed and signed by the Resident Engineer on site from Thomas Garland and Partners. In-situ method was also used for walls and slabs of superstructure of 4 blocks.

Pre-cast elements:
Four Blocks (D, E1, E2, E3) were constructed in pre-cast. Twin walls were supplied and erected by a German based company ABI whereas concrete prestressed hollowcore slabs supplier· Concrete Flooring Systems was from Northern Ireland.

Setting out:

  • The establishment of two-dimensional control network and local grids for particular blocks (for the purpose dimensional control on site and setting out);
  • Regular check of primary baselines, control frame points and benchmarks for accuracy;
  • Setting out with TOPCON 200 Series and 700 Series Total Stations on a daily basis:
  • concrete pads, foundations and strip-footing;
  • in-situ elements: columns, beams, slab edges etc,
  • linear objects: paths, access roads, kerbs etc;
  • drains, sewers and services

  • glazing and stone cladding;
  • providing all necessary grid lines for formwork and pre-cast subcontractor;

    • A low tolerance setting out of curved balconies;
    • The establishment of leveling control network and all required benchmarks on site;
    • Setting out and controlling grading excavations such as: drainage trenches, pipes laying, manholes levels etc.;
    • Transferring benchmarks to all blocks and all storeys;
