Eddington Flashcards
On Eddington you discussed value engineering opportunities with the brick framing. Can you explain?
“Elements of the design included rotated brickwork and projectect brickwork for architectural interest. This increased as a proportion across the building as the design developed.
Due to the additional labour required compared to a traditional brick bond, the cost saw an increase from £145m2 to circa £250m2. Ultimately design reduced amount of brick framing by 1/3
Reduced by 150m2 - totalling saving of circa £15k
On Eddington you discuss the measurement and costing of the frame. How did you go about this?
”- Quantified in line with NRM.
- Columns as a linear m
Build up of the GF slab included excavation, earthwork support, compacting, hardcore, blinding, DPM, insulation, concrete, reinformcened and powerfloat finish - SLAB NOT PART OF FRAME
On Eddington how did you cost the concrete and reinforcement?
”- Costed concrete on a m3 basis at £175 / m3 at the time (Aug 21)
- Costed reinforcement on a T basis at £1,500 per tonne
- Reinformcenet levels and thicknesses of concrete advised by engineer “
On Eddington you used CFA. Why? What other type of piling are there?
“Works were being done in an area with other buildings close to residential units. Determined CFA would be quieter and prevent vibrations disturbing new foundations of local buildings
’- Other type of displacement piling would be bored
- Also driven piling which can be vibrated in to the ground “
How did you VE the piling?
”- I reviewed the types of pile tests. I was advised by the structural engineer that pile tests may reduce the diameter of the concrete pile required
- Compared no pile testing (750 diam), working pile testing and preliminary pile testing
- Preliminary pile testing enabled the concrete diameter to be reduced and saved 163m3 of concrete
- OVerall saving of £300k as saved time and concrete and reinforcement
