New Building Construction: Progress Update 18
Position:- The project is on average 1 week ahead of programme with the critical activities running through the south atrium and entrance works.
Cranes & Hoist:- The structure is largely fed by the tower cranes. These are supplemented occasionally with mobile cranes on days not affected by high winds. A hoist to access the mezzanine and basement from ground level feeds the blocklaying and will supply materials for the services starting shortly.
Temporary Yellow Props: The large cylindrical yellow props have been removed now the mezzanine slab has gained the required strength. The holes formed around where the props used to be will now be made good.
Visits:- The Considerate Contractors Scheme representative visited the site again on 12/6/2012.
Future works for June
Steel Beams & Columns:- Steelwork has been erected in most of the Entrance and continues to be delivered and erected as required.
Blockwork:- The block walls that form a straight face in front of the structural secant piles in the basement are over 50% complete. The Mezzanine has also commenced with blockwork to the perimeter.The internal blockwalls that form individual plantrooms are being progressed at the same time fed by the hoist.
Ground Floor:- The north and south are now complete with the focus progressing towards the central area and the entire floor is expected to be complete towards the end of June. Large prestressed concrete beams form part of the ground floor slab that will span the large lecture theatre.
1st Floor:- The last slab to the south is 23A expected to be poured in the next week. These slabs consist of a set of precast concrete planks (temporary supported) with an insitu concrete topping with strands (steels within tubes) which are stressed (tightened at the ends) after the concrete has set hard.
2nd Floor:- The second floor on the north is complete. The first pour on the south was poured on 31/5/2012. The second floor on the south is expected to be complete by mid July.
3rd Floor:- The columns and walls (2nd to 3rd floor) have begun on the north.
