Robert Bray Assocates Case Study

SAFER CYCLEWAYS, LONDON & NOTTINGHAM New

This case study examines the latest innovation in kerbs designed to protect cyclists in cities. Initially developed for the London CS2 cycleway extension, the latest generation of precast concrete cycleway segregation kerb units has also been used as part of the Nottingham Cycle City Ambition Programme.

Robert Bray Assocates Case Study

TRAFALGAR PLACE, LONDON New

Shortlisted for the 2016 Stirling Prize, this project provides an exemplar for high density development and related external spaces which help define the project – a result of the close working relationship between landscape architect and an Interpave member.

Robert Bray Assocates Case Study

INNOVATIONS WITH SUDS & HARD LANDSCAPE - Recent Projects designed by Robert Bray Associates

Leading SuDS designers Robert Bray Associates have been designing with concrete block permeable paving for many years. They have made the most of this technology to deliver a gradual flow of clean water for amenity, landscape design, biodiversity, education and recycling on numerous schemes - several discussed in earlier Interpave case studies.

They continue to develop innovative design approaches to optimise the potential of permeable paving - notably using straightforward flow controls - and other readily available precast concrete landscape elements in SuDS schemes, exemplified in three recent projects discussed here.

Brownfield Estate

BROWNFIELD ESTATE, LONDON

With the recent completion of public realm regeneration at the east London Brownfield Estate, Interpave has substantially updated its case study on this exemplary project. Brownfield includes modernist architect Ernö Goldfinger's listed, 'brutalist' concrete high-rise blocks - including Balfron Tower - from the late 60's and early '70s.

Hazeley Case Study

HAZELEY ACADEMY, MILTON KEYNES

Interpave's 2015 revisit explores the successful long-term use of concrete block permeable paving around a state-of-the-art secondary school and its benefits for wildlife. It demonstrates the use of terraced compartments using flow control chambers and straightforward, non-specialised maintenance of concrete block permeable paving.

Cambridge Southern Fringe

SOUTHERN FRINGE, CAMBRIDGE

A pictorial tour around several linked developments in this growth area of the city. It focuses on the role of precast concrete paving – including permeable pavements as part of SuDS – in helping to define each area’s character, integrated with architectural design and master-planning.

Great Western Park, Didcot

ST GEORGE’S PRIMARY SCHOOL, KIDDERMINSTER

This RIBA Award winning school displays an exemplary approach to sustainable drainage, with a SuDS and landscape scheme integrated into the overall project from the very start. Solving complex issues, the drainage scheme utilises several SuDS techniques – including concrete block permeable paving – within a fully developed management train.

Great Western Park, Didcot

GREAT WESTERN PARK, DIDCOT

Great Western Park is being developed on 160 Ha of essentially greenfield land to the immediate west of Didcot. Once complete, it will increase the urban area of Didcot by around 20%, eventually providing 3,000 new homes and related facilities. The use of concrete block permeable paving is an essential part of an intergrated sustainable drainage system (SuDS) management train throughout this major new development.

Greendykes North, Craigmillar

Greendykes North, Craigmillar, Edinburgh

This important regeneration project in Edinburgh shows how shared space brings together all street users, including drivers, as part of the social world. The deliberate integration of traffic with other social activities reduces speeds and improves the relationship between pedestrians, cyclists and traffic. Precast concrete paving plays a key role - used to define areas and reduce speeds without signage - making external surfaces integral to the architectural design.

Orchard Village Regeneration

Orchard Village Regeneration, London

This case study explores the phased, £80 million regeneration of Orchard Village (previously known as the Mardyke Estate) in east London, master-planned and designed by PRP. It provides a snapshot of the project in 2012. Photos of the completed Phase 1 (with Phase 2 under construction) sit alongside PRP’s initial and later design drawings, demonstrating how the master-plan is being realised.

Craigmillar Edinburgh

Wauchope Square, Craigmillar, Edinburgh – Revisit 2012

An expanded and updated case study looking at how the first stages in the regeneration of the Craigmillar area of Edinburgh – previously the fourth most deprived area in Scotland – are developing on the ground. Craigmillar also includes the first concrete block permeable paving to be adopted by a local authority in Scotland.

DIY Streets - Turnpike Lane London

DIY Streets - Turnpike Lane London

This case study considers an initiative to provide long lasting, low cost improvements to an established residential area of north London. An essential component of the project is the use of precast concrete paving with a limited palette of colours and styles to establish local character and influence the way that drivers behave.

SuDS in Cambridgeshire – Comparing Costs and Performance

Permeable Paving Case Study – SuDS in Cambridgeshire – Comparing Costs and Performance

The Lamb Drove SuDS Monitoring project in Cambourne, Cambridgeshire, is important for a number of reasons. Perhaps most importantly, it demonstrates that SuDS work and should cost less than conventional piped drainage in terms of initial, maintenance and whole-life costs. In fact, the project is cited in Defra’s Consultation on The National Standards for SuDS in those terms. It also highlights the robust performance of concrete block permeable paving and suggests much longer maintenance intervals – and lower whole-life costs – than currently applied.

Adoption in Oxfordshire

Permeable Paving Case Study – Adoption in Oxfordshire 

Oxfordshire County Council has taken a positive and pragmatic approach to adopting streets and other areas using concrete block permeable paving for some 15 years. This case study discusses lessons learnt from this extensive experience, which will help to reassure and inform other authorities including ‘SuDS Approving Bodies’, and demonstrates the long-term successful application of this important Sustainable Drainage System (SuDS) technique.

Accordia Housing Cambridge

Accordia Housing Cambridge 

Accordia is a substantial, award winning housing project on the edge of central Cambridge. Its importance lies in its demonstration that it is possible for a volume house-builder to support high quality architecture and urban design. Following on from our original 2009 case study, Interpave revisited Accordia to review progress on later phases.

RBA case study

RBA case study

This case study shows that there is more to concrete block permeable paving than just meeting the latest legislative demands to help reduce flooding. It can also provide a controlled source of clean water as a sustainable amenity for landscaping, ecology and water harvesting, as a leading SuDS specialist has demonstrated on a range of projects.

Kerb Case Study

Efficient Design for Safe Construction using Precast Concrete Kerbs
Interpave has been actively involved with the Health and Safety Executive’s initiative to reduce respiratory disease. Interpave manufacturer members offer a range of kerb solutions to the HSE requirement for a hierarchical ‘AMC’ approach -

Avoid cutting
Minimise cutting
Control dust generation during cutting

This approach is clearly demonstrated in a Case Study which can be downloaded below.
