Project Facts
Sector: Education
Our Role: Sub Contractor
Location: Ilford, Essex
Client: Skanska
Project Value: £3.325 m
Duration: 18 months
This £3.5 million project for Skanska was a high specification finish project which included specialist playground surfacing, granite finished paving and kerbs, high standard brush finish concrete and tarmac works.
Scope of Works:

The external works were undertaken in a tightly restricted environment including maintaining access to the on-site car park, maintaining throughway traffic to the adjacent athletics track and included works within an internal atrium area whilst keeping access for other trades viable.

Existing contamination levels required the provision of a minimum 600mm of clean cover to finished ground level. This was achieved through careful material management and extensive testing to remediate existing material and minimise material import. The Natta package comprised all surface and foul drainage including attenuation tanks, permeable parking, and a rainwater harvesting system. Also included were: the piling mat, piling attendance, RC pile caps, RC ground floor slab, and structural topping to the pre-cast concrete beam flooring system to the structure. The existing contaminated ground beneath the 'clean zone' demanded a variety of gas ventilation systems for the car park and the school structure. The finishing works involved a variety of block paving in challenging patterns, coloured tarmac, and in-situ RC stairs and retaining walls. All finishing works were completed with seamless coordination with Skanska to enable the various other trade contractors to complete their works and successfully deliver the project on programme.


"I'm very proud of the final product. We saved our clients lots of money by value engineering the drainage design and constructed a sustainable urban draining system which included large attenuation and harvesting tanks and open swale drainage, as well as, taking cognisance of contaminated ground conditions."
