Derbyshire Development Wins Planning

12 07 2017

The Stilwell Partnership were pleased to help their long-standing client, Tapton Estates, win Outline Planning Approval for the proposed development of Derwentside Industrial Park, Belper, Derbyshire.

Amber Valley Borough Council unanimously approved the Application on 11 July 2017.

The scheme comprised the demolition and clearance of existing industrial buildings and re-use of the 6-ha site for 136 residential units.  The proposals also included access improvements and associated works.

Belper Tapton Master Plan

The Stilwell Partnership, with colleagues from the Patrick Parsons Group, put together a comprehensive package of technical assessments addressing many of the contentious issues and potential financial challenges facing development of the site:

The Transportation Assessment addressed potential future Traffic Impact and the long-term sustainability of the site.

The Travel Plan Framework provided an overall strategy to encourage sustainable transport measures; to increase walking, cycling, use of public transport and encourage more efficient car-use.

The Geo-Environmental Assessment examined the geotechnical issues on the site including ground conditions, potential contamination, and the building foundation requirements.

The Utility Constraints Assessment ensured there was adequate service capacity for future development without major investment in utility diversions.

The Flood Risk Assessment and Drainage Strategy confirmed that there was minimal flood risk on the site and that a foul and surface water drainage system was feasible within the capacity of local network.

The Noise Assessment considered the impact of noise from nearby roads and suggested mitigation measures that could be incorporated into future development.

On this proposed development, the Stilwell Partnership worked closely with the other project team members; David Lock Architects, FPCR Environment and Design Ltd and Rigby and Co, Commercial Property Agents.

Nick Stilwell, Stilwell Partnership’s founder, celebrates 25th anniversary

24 05 2017

In May 2017, Nick Stilwell of the Stilwell Partnership celebrated 25 years in business. The Surrey based practice of consulting engineers has always “punched above its weight”, and over the years has made a major contribution to the disciplines of road safety, transportation, and highway engineering.

Stilwell’s first client proposed a major development on a site in Holmethorpe. The site was locked within a triangle of busy rail lines with highway poor access.  Substantial infrastructure improvements, including a new rail bridge, were required to open the site for much needed housing.

To reduce the construction costs and potentially improve the viability of the development, the Stilwell practice introduced the traditionally risk-averse British Railways to a popular Swedish technique of rapid rail bridge construction.  This bridge construction technique has subsequently been adopted and widely used for many new rail bridges throughout the UK.

The Holmethorpe project was to play a substantial part in the growth and development of the practice.  For the next 20 years, the company progressed the project from Public Inquiry to Planning Consent and then through detailed design and construction, to completion.

Also in the 1990s, the District and Boroughs of Surrey had responsibility for the traffic management, road safety and highway engineering.  To improve efficiency, the Stilwell practice offered to take on their staff and provide a shared engineering resource for these Authorities.  This successful arrangement provided essential engineering services to several Boroughs including Surrey Heath, Elmbridge and also Surrey County Council.

In this role, the practice wrestled with the worsening problem of traffic congestion and delays at busy or complicated roundabouts.  The conventional approach of building yet more roads or larger junctions was not a sustainable solution.  Therefore, the practice looked at new ways of reducing congestion by guiding motorists through the junction, quickly and safely, from the approach to their exit.

Experimenting with white lining and surfacing, the practice developed the Spiral road markings technique.  Initially trialled at Camberley’s Meadows interchange in 1995, the technique was so successful it was adopted as good design practice by the Department of Transport.

Spiral road markings continue to be used throughout the UK to reduce traffic congestion and improve road safety.  Many road junctions constructed today could not operate efficiently without that pioneering work by the Stilwell practice.

Responding to the requirements of public and private sector clients, the practice offered an increasing number of civil and municipal engineering services.

The practice was appointed civil engineer for the design and supervision of West Wales Airport improvement.  Part funded by the Welsh Parliament, this prepared the airport to become a centre of excellence for the development and operation of Unmanned Aerial Vehicles, (Drones).

In the summer of 2007, areas of the UK were subjected to the worst flooding for many years.  The Stilwell Partnership produced a strategy for Cheltenham, Gloucestershire, an area severely hit by the floods.  Using CAD systems, historic flood information from different agencies was combined to reveal weak spots in the surface water drainage network.

The practice continues to advise local authorities, developers, and parish councils on the potential impact of Flood Risk and flood alleviation measures.

Most recently, the practice played a key role designing the highway junction infrastructure for the award-winning Pont Briwet road rail bridge in North Wales.

The Stilwell Partnership continues to make a significant contribution to Road Safety.  Nick Stilwell is a member of the Parliamentary Advisory group on Transport Safety, and the Association of Road Safety Officers.  In 2009, the Association presented the practice with the “Award for Outstanding Contribution”.

The Stilwell Partnership continues to promote good practice by sponsoring the Southern Region of the Institute of Highway Engineers.  In addition, Stilwell Road Safety, a not-for-profit venture, aspires to introduce a culture of Road safety from early school days throughout childhood and older to combat the increasing number of road deaths in the 17-25 age bracket.

The practice has been involved in many high profile and prestigious private and public projects over this 25-year history, and looks forward to meeting the challenges of the future.  In 2016, the Stilwell Partnership merged with a like-minded group of practices, the Patrick Parsons Group.





Building For Schools: Resolving Highways & Traffic Issues

23 03 2017

We have added a new section to our website describing our specialist contribution to the Building for Schools Programme and our continuing efforts to improve Road Safety around schools.

The Stilwell Partnership have successfully supported many School Building projects throughout London and the South East.  Considering issues of road safety, traffic congestion and parking, we identify safe and sustainable access arrangements for pupils, parents, and staff.

Resolving Highways and Traffic issues may be the key to a successful Planning Consent.  Our contribution can smooth the project’s progress from initial Concept, through the Planning process, and onto successful Completion.

School Expansion

To help St Joseph Catholic Primary School achieve Planning Permission for their expansion in Ealing, our Transportation Assessment evaluated the traffic generation and car parking associated with the development.  We produced a School Travel Plan recommending sustainable transport measures to minimise the impact on the local road network.

Claremont Fan Court School in Esher, planned a new sports hall.  In addition to assessing the traffic impact we produced an engineering design solution for improvements to the access road, new car park and “section 278” improvements to the adjoining public highway.  To help implement their planned expansion we designed alterations to the site drainage network and carried out a Flood Risk Assessment.

Traffic and Parking Problems

Hart District Council in Hampshire was concerned with the continuing traffic and parking problems around a number of schools and the resulting impact on road safety.  We undertook site studies and proposed a range of traffic management measures to improve road safety in the area.

Stilwell Road Safety for Schools

The Stilwell Partnership has been innovating and pioneering road safety solutions for over 20 years.  Our not for profit social enterprise srsCULTUREforSchools aims to instil a lifetime of road safety culture to our children by improving attitudes towards the safety of self and others and encouraging safe behaviour in the road environment.

Challenging Housing Development in Horley Gets Planning Consent

6 01 2017

Despite setbacks during the Planning process, perseverance pays off.  At the end of May 2014, WSP Architecture & Planning of Reigate submitted a Planning Application for a development of up to 46 high quality dwellings in Horley, Surrey. The development was to be located on land at the rear of an existing cul-de-sac, requiring highway access between existing houses.

The Stilwell Partnership were appointed to provide the following specialist engineering services for the Planning Application:

A Flood Risk Assessment & Drainage Strategy.  Developed in full consultation with the local drainage officer, the strategy ensured that the site complied with policy for restricting and attenuating surface water run-off, and reduced the risk of flooding in the wider area.  This was achieved through tactical spatial planning and widening of watercourses to provide additional flood plain storage in the west of the site, an area subject to historic flooding.

A Transportation Assessment and additional Highway design services.  The Transportation Assessment reported that the site was in a sustainable location with good links to public transport, shops, and employment opportunities.  The highway design proposed a 5.5m width carriageway with 1.8m wide footways on either side from the cul-de-sac to serve the new residential properties.  This also included improvements to the lane, a small roundabout and other sightline enhancements.

The Stilwell Partnership reports and design proposals addressing Flood Risk, Drainage and Transportation were accepted by the Local Authority without comment.  Despite this, in July 2015, Reigate & Banstead Borough Council rejected the Planning Application referring to Planning Policy issues.

An Appeal was submitted in January 2016, heard in October, and in November, perhaps about 3 years after the development was first conceived, the Planning Inspector allowed the Appeal.

The Stilwell Partnership are pleased to be associated with this successful outcome.

The Stilwell Partnership supported the successful Planning Application by Axcel Property Developments Ltd for a new Marriott hotel providing multidisciplinary design advice including Highways & Transportation, Drainage, Low Carbon Energy and Noise Assessments.

A full Planning Application was submitted for a 172-bedroom hotel on the brownfield site of a surface car park in Cable Street in Manchester’s New Cross area. The development comprised the hotel (Class C1) with associated public realm, landscaping and other associated work. Proposals included a café bar, fitness centre, meeting rooms and associated servicing areas.

Our package of engineering design services included:

A Transport Statement of the development’s transportation impact on the local highway network. Our assessment considered sustainable forms of transport, including opportunities for walking and cycling, and the accessibility to public transport. We also considered servicing and emergency vehicle access. Our assessment concluded that the development could be accommodated without detriment to vehicular flows and road safety.

A Drainage Strategy, to minimise the impact on the wider area from surface and foul water from the proposed development. The very confined site limited the range of sustainable drainage options. An attenuation solution was identified to control the surface water run-off.

The Noise Assessment highlighted the application site was in a relatively noisy area impacted from road traffic noise on the A665 Addington Street.  Mitigation action proposed triple glazing to the bedrooms on the assumption the hotel would have air conditioning, to control internal noise levels to meet the standards set by WHO and BS 8233:2014.

Manchester City’s Planning Policies place great emphasis on decentralised energy schemes in the City centre. Using our CHP modelling software, the Sustainable Energy Assessment determined that the proposed development would be able to potentially contribute towards a future local district heating scheme and achieve an improvement of at least 15% CO2 emissions based on the predicted energy demand.
