Collins Demolition secured a significant project to clear the former Hewlett Packard head quarters in Bracknell. The demolition is in preparation of an earthworks package secured by Collins Earthworks. Two members of the group working in unison to reduce program and deliver a finished pre-construction enabling package to the client.
The scheme included the demolition and redevelopment of the 5.21 acre site in Weybridge into a single warehouse unit with 14,294 sq. ft of grade A ancillary offices, car and cycle parking, access and landscaping. The DC1 unit is surrounded by existing operational industrial units, a residential area, the Metropolitan Green Belt, the former aerodrome and Brooklands Site of Nature Conservation Importance (SNCI). SGP’s design responds to the eclectic mix of neighbouring structures, matching height closely with existing buildings.
Collins Demolition made swift process of the structural demolition across the scheme followed by break out and processing of the existing foundations to produce a engineered plateau to be passed onto the vertical build team
The project was completed both within budget and ahead of programme.
The site covers an area of approximately 17ha and is irregular in shape. The site is the location of the former A, C and D Blocks of the Royal Ordnance Factory, Radway Green. Our work on this project involve specialist licenced asbestos removal to allow demolition of a series of existing factory blocks and structures across the project.
Following demolition our earthworks division mobilised to begin the extensive break out of site won slabs & foundations to be processed and used as aggregate across sections of permanent works.
This project involved providing a ‘turn key’ pre-construction enabling scheme. This required the demolition of the famous timber engineering buildings and associated offices where the timber for the ill-fated Titanic was produced and formed. Following the sizable demolition process where we reclaimed and recycled over 2000 tonnes of ferrous steel, the works then involved the removal of footings and relic foundations, re-engineering the ground including cement stabilisation to form a building formation to the required level.
The size of the site was approx. 580,000 sq. ft and was demolished, remediated and re-engineered in 8 weeks.
We worked closely with our client TSL to allow the piling and construction process to begin following week 3 of our commencement.
The site was originally part of the Harlow and Wolff works where the famous Titanic cruise liner was built, it was a unique experience to work under the shadow of the famous Samson & Goliath cranes which have been in the Titanic Quarter skyline for over 50 years.
The project involved the removal of relic structures and the remediation of the site to eradicate free flowing hydrocarbon contamination and impacted soils. The remediation process involved the excavation of the contaminated ground followed by the controlled treatment of the spoil to reduce the level of contamination to site target levels denoted by the Environment Agency. The works also involved the re-engineering of the site to formation level which included the modification of the soil with cement stabilisation, all to allow the construction of Europe’s first 3-storey, vehicle access warehouse.
- The works were undertaken under the guidance of specialist UXO consultants to allow the safe excavation of the site as the site was heavily bombed in WW2
- Tidal water was a significant problem on this site as the site is less than 200mtrs away from the River Thames causing working hours to be restricted and implementation of water management solutions
- 4,000 m3 of hydrocarbon-impacted soils were remediated and reused on site
- 38,000 m3 of material was re-engineered using cementitious binders
