Latest news from Carnon

Posted on: December 3rd, 2018 by carnoncontracting

Carnon Contracting have achieved practical completion for their work at the new 18 space Downs Road car park in Looe for West Looe Town Trust. The tarmac surfacing work has now also been completed with tree planting of the berm to follow in mid November to complete the contract.

Carnon Contracting have also been on site in Newlyn working for Symons Construction installing piles and geothermal boreholes for the new RNLI Penlee Lifeboat station. The odex piles were cased down to rock, which varied between 13m and 22m across the site, before a rock socket was drilled. The piles were reinforced with a full depth bar and a 6.5m cage then grouted. The 2no. geothermal boreholes were cased to rock using 168mm diameter casings to rock and then both the 140mm diameter bores were drilled to a depth of 103m. Carnon Contracting also installed the above ground loop pipework and connected it into the manifold.

Retaining wall stabilisation in Hayle

Posted on: September 14th, 2018 by carnoncontracting

A collapsed retaining wall behind the Central Garage in Hayle is currently being stabilised by Carnon Contracting. Appointed by Adrian Nicholls Ltd for the work, the solution was developed by James Lockyear Associates and includes rock anchors and a mesh to stabilise the slope as the collapsed material is removed. A new anchored cast in-situ reinforced ground beam will be constructed upon which a new block wall with granite facing will be built by Adrian Nicholls. The anchors are extended through the new wall, the void behind backfilled with no fines concrete and the drive above resurfaced. The R25 anchors were installed using Carnon Contracting’s CID 80 Marini mast mounted on an 8T excavator. Work on site is due to be completed in October 2018.

Work in progress in Looe

Posted on: September 14th, 2018 by carnoncontracting

Work is ongoing at the new Downs Road car park in Looe. Carnon Contracting have been employed by West Looe Town Trust to strip the site and install a gabion retaining wall along with the ground works and landscaping for the construction of a new 18 space car park. Due to the sloped site, the drainage solution involves sub surface dams and permeable paviors to control surface water and run off. Completion is anticipated in early October 2018.

Essential safety work at St Ives Station Car Park

Posted on: August 1st, 2018 by carnoncontracting

Carnon Contracting has recently completed extensive essential repairs and stabilisation works to the embankment face in St Ives Station carpark on behalf of Cormac. The embankment, which ranges between 12m and 16m high, had been showing signs of structural instability in places.

A total of 485no ground anchorages have been drilled into the rock face to secure the surface to more stable layers beneath. The installation of rockfall netting, cables and plates along with areas of corbelling at lower levels has completed the stabilisation project.

Installation of the anchors has been supplemented with a layer of reinforced sprayed concrete to give added stability and protection against further deterioration.

Posted on: June 15th, 2018 by carnoncontracting

Carnon Contracting are currently on site installing 195 no. 219mm diameter Odex piles to facilitate the construction of a commercial development at the Bickland Industrial estate in Falmouth.

Midas Construction are the principal contractor, with Carnon Contracting working for Morcom Construction Ltd who have been appointed to carry out the ground works package. The site was levelled using an earthworks cut and fill exercise, and then piles were installed through the fill material to found in the Mylor slate formation beneath.

The piles are end bearing and range in depths between 6m to 19m. They are reinforced with either a central 25mm bar or, where piles have lateral loads, 6x16mm diameter reinforcement cages are installed up to 8m in length.

The contract duration is four weeks, and due to complete this month on programme.

Mylor Boatshed contract gets under way

Posted on: April 10th, 2018 by carnoncontracting

Mylor Bridge

 

Carnon Contracting are currently on site installing 54no. 219mm diameter Odex piles to facilitate the construction of a new boatshed in Mylor Bridge for Brady Construction. Piles vary in length from 6m up to 9m with a 190mm being drilled into the bedrock, and are being installed by a Beretta T44 drill rig. Value engineering by Carnon Contracting during the tender stage reduced the number of piles by optimising the design and reducing pile lengths and reinforcement diameter where possible. Target completion is mid-April to allow the structure to be erected at the end of April.

New Marini Mast

Posted on: December 20th, 2017 by carnoncontracting

Carnon Contracting expands its drilling capability with an investment in a new Marini CID80 drill mast fitted with a powerful MA100S ID Head. The lightweight mast can attach to an two- or five-tonne excavator using a bracket, allowing excellent maneuverability. The Marini mast is well suited to soil nailing, ground anchoring and micro piling applications, and better equips us to maintain the ability to access restricted sites in Cornwall and the South West.

The Marini mast is also available for contract hire. Please contact our office for further details.
