RD Residential – Garden Studio

This project involved the construction of a timber-built garden studio in West London.

Screw piles were a preferred choice for the foundations, as the proposed location for the structure was at the base of a mature tree and in a tree root protection area.

The access to the site was also restricted allowing only hand held equipment to be used.

Both the customer and contractor for the build were new to screw piles and had been referred to us by their structural engineer, all the information was provided to each party and the system and method was approved.

The 60R product range was chosen due to the loading and the structure, and the unique 400H Hand Held anchor driver was chosen for the installation. The ground conditions varied across the site so additional extensions were used to achieve the required torque for the design load.

The foundations for the garden studio were successfully completed and the contractor was very happy with the service received:

“From start to completion ABC Anchors were a pleasure to deal with, very supportive, and easy to talk to when queries arose.  We would highly recommend both their products and service and will definitely be using them again for any piling needs we have.”

Another to look out for! Woodman’s Treehouse

Thursday 22nd September 8pm on Channel 4

The building of the treehouse was filmed for the first episode of the new series of George Clarke's Amazing Spaces.

ABC Anchors are proud to be involved in these projects as the manufacturer of the piling work needed for the foundations . Dursley Tree House and Woodman’s Tree House are just one example of the solutions ABC Anchors has to offer to most screw pile applications.

Don't miss the opportunity to see our piles in action!

 

 

Underpinning from Inside a Building

Problem

The Customer has experienced subsidence of the property due to trees in the back garden and fluctuations in ground moisture levels, causing the walls to move and cracks to appear.

Access to the outside wall was not possible so underpinning needed to be carried out inside the building. In addition to the subsidence, the customer was also looking to redevelop the extension from single to two storeys. 

Solution

Using the ABC 400H hand held torque and keeping the powerpack outside the house. The Piles were installed quickly and quietly, underpinning brackets were then fitted and pre-loaded to design load. This was then back filled around the piles and the floor reinstated. The building is now ready to be developed to a two storey.

Warwick Castle – Site Jester oversees the Screw Piling

During the pile installation work at Warwick Castle for the new Knights Village (A Medieval themed experience), piling work was interrupted by a photo shoot, for the recruitment of a new young Jester to entertain guests in the new village.

Julia’s House Children’s Hospice

This project involved installing 6 quantity 60RL* screw piles to support a small wooden Cabin.

Screw piles were the preferred choice of foundation for two reasons, firstly as there were tree roots and secondly, the ground dropped away by up to 1meter in some pile positions.

Using our 400H hand held torque head 2 rows of 3 piles were installed with the front 3 piles being installed to ground level and the back 3 protruding above ground level by approximately 1m.

As a precaution a cross brace of the 3 rear piles was designed to be used to ensure lateral stability.

The piles were terminated with a flat 200mm x 300mm plate which allowed easy connection of the steel ring beam for the cabin to sit on.

Once installation was complete it was found that the stability of the piles was adequate and cross bracing was not required on this occasion.

 

Customer’s feedback-

 A brilliant system which I wouldn’t hesitate to use in the future

Maurice Fishlock

 

*the 60RL is a light duty of the 60R, a cheaper option for low loadings, the difference between the 60R and 60RL is the tube thickness.

Easter Glentore Wind Farm

Easter Glentore is a wind farm situated between Glasgow and Edinburgh. This project entailed the jacking of two substation transformer units back to their original level.

The very poor ground was a mixture of soft undisturbed peat along with 5.5m of infilled stone that had over a period settled and caused the substation units to subside on one side. The movement of these units, both weighing in at around 12t was putting the underground electricity cables which are fed from the wind turbine at risk of damage.

ABC Anchors were asked to install screw piles along the subsiding edge of both substation units and bring them back to level using underpinning jacking brackets.The project needed careful planning due to the potential damage to the underground cables during the pile installation and the cost of having the wind turbine shut down for longer than necessary.

As always with the underpinning process, careful excavation to expose the footings was the first operation. The units were both set on 300mm thick concrete slabs so once the underside of these had been exposed localised pockets could be cleared away under the edge of the slab to allow for the jacking plates. The piles could then be installed using the ABC 500X torque head mounted on a 5t excavator. 4 piles were used on the smaller unit and 7 and the larger one. All the piles needed to be installed to 4kNm of torque which meant they were 6m deep in order to penetrate the hard undisturbed layer which started at 5.5m.

Once all the piles were in place the jacking brackets could be fitted and the jacking up process could begin. Care is always taken during this process to ensure the structure is loaded equally and no damage is incurred.

40kN hydraulic jacks were used on each pile making the leveling of the units a simple operation. With the piles all preloaded equally and the units back to level the jacking brackets could be locked in place using the M16 threaded bars and the jacks removed.

Finally the excavated soil is replaced with a type 1 scalpings and compacted to ensure there is no movement between the piles and the foundation.

Customer Comments

This was our first time using a screw piling system and I would highly recommend it, I would give the guys a 10/10!

CLM – Ferry Bridge

Ferry Bridge is an historic suspension bridge in Burton on Trent which was in need of refurbishment work during October 2015.
In order to carry out the repairs to the bridge a scaffolding system was required to be set up to allow access for the contractors. The Scaffold system would rely on the screw piles to act as the full support. The loading on the anchors would be both the weight of the system and also the side loadings from the river current and any debris floating down stream.
