Case Study -
Tandem II, Colliers Wood, SW London
Mowlem came to GeMech for the foundations package to a mixed
site comprising multi-storey construction, residential and commercial
units. A compliant scheme called for::
- Piled foundations (with tension loads) to be constructed using
- Piled floor slab to be constructed on augered piles.
Upon examination of the soils report and structural drawings
from the Consulting Engineer, GeMech suggested an alternative
and somewhat novel scheme which would utilise the materials on
site, reduce the cost and design of the reinforced concrete slab
and reduce the number of piles.
In conjunction with John Allan Consulting, GeMech provided a
stone column solution to enable the use of a ground bearing reinforced
concrete slab combined with permanently steel cased bottom driven
piles, driven to a sufficient depth based on a static pile calculation
and with sufficient reinforcement that compressive, tension and
moment loads were all catered for.
According to John Mowlem, the GeMech scheme as adopted saved time,
money, excavation, load and cart muck away muck to tip and of course
concrete. It was according to Mowlem a prime example of value engineering
at its very best.
