Completed in December 2016, this new development aimed at over 55s - assisted senior living - consists of 76 apartments and five bungalows for social or affordable rent, and was the first housing scheme commissioned by Warwick District Council in 30 years.
The homes have been designed in accordance with:
- Housing Quality Indicators
- Lifetime Homes
- Secured by Design and
- Code for Sustainable Homes Level 4.
As the development is located on a steeply sloping site on the corner of a busy road close to the town centre, access was difficult. To overcome these challenges an off-site construction solution was developed, which involved a lightweight cold-rolled steel panel system.
As well as decreasing deliveries and programme, this solution also created a significant reduction in foundation loads. The steel panel system was designed by a specialist contractor, whilst Hydrock designed the foundations, retaining structures, and a reinforced concrete structure which was necessary due to the sloping site.
The drainage design had to carefully coordinate with the existing and new levels, with HV cables providing additional complication.
The client wanted to minimise the volume of material being removed from site, so we undertook a detailed cut and fill balance exercise to provide the optimum solution which still allowed the drainage to work. Hydrock also undertook S278 design work for the entrance to the site and nearby pedestrian crossing.
All works were carried out in a BIM Level 2 environment.
An early engagement meeting was held with all stakeholders. This allowed all parties to meet and understand the various drivers and pressures on the project.
Use of BIM
Hydrock used Revit software to produce a 3D model of the proposed building structures.
We collaborated with the design and construction team and 3D information was shared through a common data environment process and used to coordinate the structural engineering design with the other design disciplines. The model was also used to generate the structural engineering tender and construction information.
BIM software provided the following benefits:
- Improved design coordination between design disciplines.
- Faster delivery and improved reliability of structural engineering design documents.
- Faster response to design changes and quicker to assess alternative design solutions.
- Clash detection carried out during the design period, avoiding construction delays arising from clashes discovered on site.
- Improved visualisation of the design proposals.
