A2 Dominion Bicester Eco Village

September 18, 2020
 

A2Dominion’s development in North West Bicester is a 393-home project, aiming to deliver the most sustainable living in the UK for its residents. With the homes designed to achieve true zero carbon rating, delivering energy efficient, good quality affordable housing is crucial to the success of the project. Timber systems were therefore an ideal fit for the priorities of the ambitious task at hand.

The project at Bicester was the UK’s first eco town, designed to achieve high standards of environmental sustainability. Stewart Milne Timber Systems worked with A2Dominion and Willmott Dixon, the main contractor, to provide its Sigma® II Build System for 94 of the first 393 homes as part of the “Examplar” phase of the project.

  • Homes attained Code for Sustainable Homes (CSH) Level 5.
  • Fabric first approach, complemented by renewable technologies to create a sustainable community.
  • Air testing conducted prior to first fixing, building in assured performance of the fabric.
  • Pre-assembled flat roof modules and insulated floor cassettes meant pair of semi-detached homes fully insulated and weathertight in 72 hours.
  • Safe and efficient way to complete homes on site.
  • Off-site construction benefits – quality of the timber systems assisted by precision engineering compared to erecting on site.
  • Reduced costs on preliminary site preparation.
  • Reduced health and safety risks.
  • Featured the UK’s largest domestic solar panel array at 17,500 sqm mounted on all rooftops.

Case Study

University of Gloucestershire

September 15, 2020
 

The University of Gloucestershire needed to relocate their business school from their Cheltenham Campus to the Oxstalls Campus in Gloucester, but faced environmental and planning challenges with a time critical factor of completion by September 2018. The site was a monumental conservation area, providing challenges in the ground – the site of Roman ruins which needed to remain intact. All challenges were overcome, with early engagement with the architect, and a robust communications strategy across the whole project team.

This was Vinci’s first student accommodation in timber frame. The client saw timber frame as a solution that would deliver the robustness required by student accommodation whilst offering the lightweight structure they needed, which complemented and respected the historical importance of the listed buildings in the area. Timber frame foundations are lightweight enough to ensure preservation of the former Roman settlement would remain undisturbed during the build whilst being robust enough to fulfil the build criteria. The structural design solution was engineered specifically to reduce load bearing points, avoid critical ground areas and improve on overall building performance through ‘Superdry’ timber. The student accommodation in Gloucester was a huge win for the developer as the collaboration between Vinci Construction and Stewart Milne Timber Systems worked up a design that could operate in the conservation area, incorporating the flexibility needed to address the challenges of this build. These solutions met the environmental, timing and quality challenges posed by this site, ensuring energy efficiency, increased air tightness, reduced acoustics, reduced energy consumption and completed build in only 24 weeks. The density of the buildings and access to site meant a key communications and operations strategy was implemented by all parties from the outset.

The site was a huge success due to:

  • Speed of build – imperative as students needed to take occupation within a year. 2 blocks were built at once.
  • Lightweight structure for preservation of Roman Settlement – foundations were engineered to meet this demand.
  • The Blocks were designed incorporating progressive collapse with floor cassettes designed to ‘triple span’ over loadbearing walls.
  • Limited ground disruption – through hard standing for the Mantis Static HDT 80 crane.
  • Superdry Timber (Ultra-Joist) was used within horizontal make-up of the structure.
  • Achieved the highest score on record for Health & Safety audit.
  • Adopted a hybrid Pod and Panel approach to increase on-site productivity.

Located on a former school site, calfordseaden provided architectural and principal designer services to transform this location into nine modern new dwellings for the executive and/or large family housing market. With the site boasting four different house types, it was key to balance a contemporary style and generous room sizes with a unique feel throughout each.
Features include offsite manufactured timber frame construction, bespoke house design and high specification components, including individual external cladding materials. Sustainable, low carbon materials were utilised alongside these features, together with Knauf Supafil Frame® insulation for a true fabric first approach.

This was the regeneration of an unsecured derelict site of brownfield land. Building on this site led to a reduction of anti-social behaviour, created a sustainable development and gained support from the local residents who were consulted throughout the planning and construction phases. The developers also engaged with the local community by making a charitable contribution towards the North Stifford Village group for their armistice preparations and building concrete bases for new seating around the village war memorial.

The teams worked in partnership, holding regular design team meetings and ultimately successfully delivering their common goal.

  • Completed ahead of schedule with early timber frame completion.
  • Completed below the approved cost plan.
  • Built to quality exceeding expectation.
  • Delivered highest health and safety standards.
  • Higher than average scores on the Considerate Contractors Scheme site reports.
  • Development used as pilot project to inform energy efficiency of future schemes.
  • Key driver was to unlock funding for local infrastructure improvements including local road network.

Key Facts

  • PROJECT: Crest Nicholson Paintworks Exemplar Project
  • LOCATION: The site is located adjacent to the existing Paintworks development, on the River Avon, in Bristol
  • CLIENT: Crest Nicholson
  • SIZE: Paintworks is a mixed-use development in Bristol with the scheme comprising of the re-development of a 2.47 hectare brownfield site, and the creation of 11 live / work units, 210 houses and apartments and 6,700sqm of commercial floor space. The Crest Nicholson Paintworks Exemplar Project with Stewart Milne Timber Systems consisted of 96 units, split into 8 terraces of houses and 4 Blocks of Flats, with the timber frame element being an order value of circa £1.2m
  • TIMING: 18 Months

Type and size of project

Based in the heart of Bristol’s Creative Quarter, the original paintworks site was built in 1850 and used as a Victorian paint and varnish factory. This tight inner city site required speed and quality of build to deliver the project on time and within budget.

The development was to include a mixture of high rise concrete frame structures, including residential apartments and commercial accommodations, and timber frame townhouses with a high specification of external and internal features. As the scheme focused on the use of cycle routes and pedestrian links, logistical access to the units had to be accounted for in the project. There was also a requirement for the project to meet CSH4 and BREEAM Very Good standards, with a key focus on energy efficiency and sustainability.

Crest Nicholson, one of the UK’s leading residential property developers, appointed Stewart Milne Timber Systems to provide technical and operational support to design, manufacture, supply and erect timber build systems for the project.

The exemplar project phase had a start date of late September 2015.


Description of project

To address the construction needs, sustainability objectives, and on-site challenges of the project, a timber frame solution was utilised that involved small panels and loose joists that could be pre-loaded into position and then manually erected. This addressed the challenge of only one crane being available on-site, by minimising the “hook time” on this single crane. If large panel, floor and wall cassettes were utilised, additional cranes would have been required, which this tight inner city site could not accommodate.

A key driver in the specification of timber as the central construction method, was to meet the objective of reducing energy consumption. The low carbon credentials provided by a timber fabric construction contributed towards achieving this objective, along with speed and efficiency and the ability to work within the constraints of the phased occupation of the site.

In addition to energy efficiencies, the use of off-site construction with Stewart Milne Timber Systems brought several benefits to this project. The access limitations of the site for material offload and distribution meant that a panelised timber solution minimised site deliveries. This enabled a just-in-time delivery of timber panels and cassettes to be loaded directly into the working area, rather than composite traditional materials being double handled.

The overall cost of the project in timber frame was also very competitive due to speed of build and control of work in progress. Utilising Stewart Milne Timber Systems solutions ultimately enabled the buildings to be constructed quickly and safely ahead of programme, without compromising on quality. The timber frame construction method also enabled greater cost certainty when benchmarked against masonry composite building materials.

This exemplar project by Stewart Milne Timber Systems was completed in late March 2017.

Case Study

Larkhill, Salisbury

August 11, 2020
 

The MOD awarded their relocation scheme at Salisbury Plain to regeneration experts Lovell, involving the construction of over 917 homes across three sites in 2 years, to a strict deadline. To achieve this, offsite timber frame was the solution. The construction of the 450 properties at the Larkhill site was divided equally between two timber specialists – Stewart Milne Timber Systems and Taylor Lane Timber Frame – an unusual approach. The companies set milestones with their speed of build. With a handover rate of 16 houses every 10 days, the fast-track homes project is an industry exemplar and actively promoted by both companies as the future of building.

The achievement reached on the Larkhill site has been phenomenal – 2 rival companies building on site at the same time, both in timber frame, both increasing the number of plots built on site from 10 to 16 to meeting extraordinary completion deadlines. This shows what can be achieved when a collaborative, transparent and organised approach is taken by both parties.

  • Collaboration – Rival companies successfully working together on site. Both teams worked with Lovell from concept and design to current onsite build.
  • Speed of build. Both companies delivered 5 units a week, accelerated to a combined 16 units being completed on site every ten days. This project delivered exceptional levels of design, detail and delivery evidenced by delivering up to 16 units per week over 34 weeks.
  • Specification of the product. Found best solution to achieve thermal performance via design for manufacture, reduced risk, deliverability, ease of construction on site.
  • Reduced impact on local community and on the environment. Speed of build meant reduced loads, reduced traffic, fewer people on site, lower community impact.
  • This £250 million contract is part of Lovell’s largest ever scheme.
  • Daily meetings held by SMTS, TL and Lovell ensured exceptional communication between all parties. Both specialists showed great mutual respect regarding their shared objective.
  • Lovell requested certain key components be sourced through single suppliers to ensure consistency of finish. Both specialists were happy to work on this basis.
  • On time on budget delivery of the project. Everyone stepped up to meet the deadlines.

Case Study

Barry Waterfront, South Glamorgan

August 4, 2020
 

Taylor Wimpey were looking for an affordable offsite solution to provide the required number of units within budget and programme utilising as much offsite production as possible.
• The decision was taken to use a pre-insulated timber frame external wall system using 100mm PIR insulation.
• The wall system was fitted in a controlled factory environment enabling a high level of quality and for the units to be insulated before the houses were watertight, speeding up 1st and 2nd fix on site and resulting in the houses being completed more quickly.
• One result of the speed of build was a realisation of capital at an earlier stage of the build than previously anticipated.
• Pre-fabricated floor cassettes were delivered from the factory and craned into position providing a higher degree of quality and a safer method of working.
• The fascia and soffits were also fitted by the erect team to enable the roofer to have the houses and apartments watertight immediately.
