Construction of a new secure warehouse facility; comprising two separate building structures. Building one provides office accommodation facilities over three levels, a warehouse facility and two storey specialist storage facility encompassing double-volume intelligent storage equipment, as well as a number of cold hold refrigeration storage units. Building two is a standalone vehicle maintenance workshop, which contains specialist vehicle testing machinery and servicing equipment.
Following site surveys and results from investigative reports, the ground was found to be significantly contaminated from previous use of the site. Despite being a construct only contract, we helped the client through the design process, finding most cost efficient solutions that maximised reuse.
We had to raise the site ground level as a result of site investigation and thus required changes to the designs. Remediation works were needed to manage the contamination and included excavation of materials, mixing it with clean / inert materials to reduce contaminations levels and reusing on site. Under strict controls, the works were fully compliant to ensure safety of the workforce.
We adopted an early warning process using the NEC proforma and through working collaboratively with the Employers Agent and our groundworker and M&E supply chain partners, we managed to develop designs which saved the client money, like rationalising the pile and mat make-up and size and installation methodology, which avoided contamination arisings. Substantial earthworks movement were closely managed with commercial neighbours and residents nearby through daily liaison and by regular updates on our site information board.
The value engineering designs saved the client over £1.5m. One of those included using a sleeved piling system with reduced pile diameters that avoided contaminated arisings saving both time and £540k in disposal costs.
In addition to achieving 100% recycling during the groundworks phase, we also installed and maintained bird feeders and planters throughout the project to encourage biodiversity.
25% procurement was with small businesses and payment periods were kept to throughout the project.
Despite the groundwork and logistic challenges, there were zero complaints and through innovative ideas like using a ‘Thumbs Up’ sticker to denote plant safety, the team scored an average of 44 on their CCS visits.
5 work experience placements were offered to students at London South East. Additionally, a graduate successfully completed her apprenticeship and is currently employed by GT as a Trainee Technician. In addition, the team donated 60 biscuit boxes to Queen Mary’s Hospital to thank the nurses, doctors and staff for their dedication, helping the community through the Covid pandemic.
An Operations Manager remained on site for six weeks post completion to ensure that end users were satisfied and looked after. Our Facilities Management team managed after care for 12 months.
