Pebsham

This 'Design and Build' project  at Pebsham HWRC has seen our team build an entrance road leading to a split level structure where customers can park on a ground level tier and have ease of access for depositing their recyclable items into skips on a lower tier.

The team have installed a small pedestrian and vehicle bridge at the site entrance which crosses a stream, and with the waste centre situated next to a water course, attenuation tanks have been incorporated and oil interceptors beneath the location to capture any potential run off from oil or other pollutants - ensuring that the area remains ecologically sound.

As a further environmental initiative the team used the most up-to-date plant to ensure reduced noise levels caused by the works. Low Temperature Asphalt was used in surfacing. Drainage utilised recycled plastic pipes and attenuation cells. All imported aggregates were recycled materials. Excavated soils were sent to another construction site (not Colas) for construction fills (rather than landfill at tip).

July 2012

The project was completed by the end of July 2012.

July 2012

Colas installed our own proprietary bridge jointing system 'C - Joint'.

July 2012

A reinforced concrete ramp connects the lower operational area with the segregated higher level for members of the public.

July 2012

The bridge was completed.

July 2012

External lighting was installed by Colas' in-house electrical team.

Timeline 15 Start Lighting

July 2012

Pre-cast concrete beams for the bridge deck were installed at night as it was necessary to close the existing public carriageway to provide safe access for craneage.

July 2012

A new bridge was formed across a stream connecting the primary access road with the new development.

June 2012

To restrict surface water flows during intense flood conditions Colas designed and constructed a sustainable underground attenuation system.

June 2012

All imported aggregates for sub-bases comprised recycled materials processed and produced in accordance with WRAP protocols.

June 2012

Colas designed and installed a safety fencing system to protect members of the public when container changeovers are required.

May 2012

The ground bearing slab for the lower operational yard area was formed using fibre reinforced concrete.

May 2012

The new works were immediately adjacent to an existing water course and drainage outfalls were carefully constructed.

May 2012

High quality fencing was chosen for perimeter security and painted black to minimise visual impact.

May 2012

The concrete piers for high level public access walkways in the HWRS were formed using mass concrete cast in-situ.

 Timeline 9 Concrete Piers

May 2012

The site required the design and construction of a reinforced earth embankment to one side.  

April 2012

A principal retaining wall was constructed in-situ of cast reinforced concrete.

March 2012

Excavated materials surplus to requirements on site were sent to another location where they were used in construction fills.

Timeline 2 Earthworks

March 2012

Existing operational yard areas adjoined the new construction and drainage solutions had to take into account this interface.

February 2012

Works at Pebsham commenced in February 2012.
