Erith Park wins RICS award!

Erith Park has won London Regeneration Project of the year at the London Royal Institute of Chartered Surveyors Awards (RICS).

Clarkebond provided civil, structural and geo-environmental engineering services on the Erith Park project, a £130m, 10 Ha mixed residential development which replaces the former Larner Road estate of 8 tower blocks.  Following extensive work, the area previously renowned for social disorder has been transformed into a desirable location.

The award was presented at a ceremony in London on 4th May. 

“We are delighted that this project has been selected by RICS as one of the most inspirational regional developments”, said Jon Palmer, Clarkebond Director.

The RICS award comes just days after the major regeneration scheme achieved gold in the annual Considerate Constructors Scheme’s (CCS) National Site Awards.

Clarkebond was heavily involved in the design development process of the project all the way from the pre-planning stages through to construction and overcame significant challenges on the project relating to historic site use, topography, geology, man-made features and compliance requirements.

The original estate had been built on an abandoned clay quarry, partially backfilled in the ‘70s with random fill, which contained a significant level of contamination and presented a potential risk to the underlying chalk aquifer.  Through close consultation with the Environment Agency and detailed quantitative risk assessment, Clarkebond was able to establish a series of protocols for adoption in the construction to enable development without the requirement for extensive site remediation. A highly varied topography and a 13m difference in level across the site presented a particular challenge to the required high density development and to achieving compliance with the London Housing Design Guide, Lifetime Homes Design Guide and Code for Sustainable Homes Level 4.

Much of the new development was also required for disabled occupancy and all site areas were required to allow for disabled access. The site being a bowl shape also presented a particular drainage challenge to provide protection for all dwellings against flooding from a potential off-site overland flow exceedance event. Reprofiling of the site involved moving 70,000m3 of earth. An earthworks balance was achieved using all granular demolition arisings and no contaminated soil was removed from site. Additional challenges were presented by the presence of previously unknown Thames Water sewer protection slabs that required some clever design solutions.

Clarkebond also undertook the design and construction of a new access road to create a new gateway feature.

Clarkebond was able to address all constraints to achieve the objectives of the development and code compliance. The structural design and drainage were designed to provide fully effective protection of the underlying chalk aquifer from potential contamination pathways. Apartment blocks extend up to 6-storeys, accommodating a variety of unit sizes and were designed to allow for conventional concrete frame construction with little or no recourse to transfer structures, providing a significant cost advantage, assisting viability of the essentially public and affordable housing development. 

The success of Phase 1 has promoted continued confidence in Phase 2, now on site, which will complete a further 242 homes by 2018. 

The project now goes forward to the RICS national competition, with awards in October.
