Case Study: Infrastrucure Projects - John Lawrie Tubulars

 Client:

Van Elle

Location:

London, UK

Project:

Supply of steel tubulars for use  as piling

Casing Pipe:

457mm and 339mm

Summary of reuse/resource efficiency

John Lawrie Tubulars’ repurposed tubular products and bespoke procedures saved this project 629.43 t CO₂e. (That’s a 97.21% saving over using new prime steel products).

Brent Cross West Thameslink Station, due to open in 2022, is the first major new mainline station in London in over a decade. It will be positioned on the Midland Mainline between existing Hendon and Cricklewood stations enabling through journeys from Luton to Brighton.

For this project John Lawrie supplied 1,843 meters of 457 and 339mm pipe to be used as piling for the foundations of the slow line platform at Brent Cross West Station.

The project will the client install a total of 193 CHS piles using two Colmar T10,000FSC RRV machines; one with a vibratory attachment (Movax) and one with an impact hammer (BSP) to drive to design level.

Montrose Port Authority

Location:

Angus, Scotland

Project:

Supply of steel casing pipe for use as piling

Amount supplied:

2,500m of 339mm diameter

Summary of reuse/resource efficiency

Work completed at the Angus harbour on a £7.7million upgrade of two quayside berths, which now enables the accommodation of larger vessels. We supplied steel casing pipe for use as piling on the project, with around 2,500m of 339mm diameter pipe being required for the initial phase of work. The pipe was despatched from our 15-acre storage facility in Montrose, which generally holds around 100,000 tonnes of tubular stock at any one time.

The piling work was carried out by building and civil engineers Farrans, and ground engineering firm Van Elle Ltd. and involved steel casing pipe being driven into the ground to depths of 30m. These steel piles are now helping to support the foundations for the expanded quayside, which was fully operational as of autumn 2019.

Client:

Roger Bullivant Limited

Location:

Edinburgh, Scotland

Project:

Supply of steel tubulars for use as driven piling

Casing pipe:

8316m of 178mm and 10,016m of 244mm

CO2 saving:

2,400.93 t CO2e

Project summary:

Roger Bullivant Limited (RB) was employed to install tubular steel piles required to support a new housing development at Waterfront Plaza, Leith, Edinburgh on behalf of Cala Homes (East) Scotland and Port of Leith Housing Association.

The Waterfront Plaza, phase 1 of 4, is a residential transformation of long-term disused land at a prominent section of Leith’s waterfront, including the creation of 388 new homes along with 1500sq.m of flexible workspace.

John Lawrie Tubulars supplied 8316m of 178mm diameter pipe that were installed to depths of up to 14m and 10,016m of 244mm diameter pipe which were installed to depths of up to 16m, all of which were repurposed from the north east of Scotland’s oil and gas industry.

Due to adverse ground conditions, steel tubulars were the selected piling method for this project, and thanks to the reduced carbon footprint of our repurposed steel tubulars, a reduction of 2,400.93 t CO2e was achieved.

East Linton Station

Project

Supply of repurposed steel casing for a network rail installation at east Linton station.

Casing Pipe

Over 1200mtrs in 140Nr. 273mm piles

Summary of reuse/resource efficiency

Using John Lawrie Tubulars’ repurposed tubular products and bespoke procedures saved this project 293.73te CO2e. That’s a 97.21% saving over the production of new prime steel products. John Lawrie Tubulars was commissioned by long-term client, Van Elle, the UK’s largest ground engineering contractor, to supply repurposed steel tubulars for the use of piling at a Network Rail station in East Lothian.

In January 2015, Network Rail agreed to develop proposals for a new station in East Linton with the objective of providing a new two-platform station on the East Coast Main Line. A new fully accessible station has now been completed, providing direct access to communities on both sides of the railway via active travel – walking/cycling paths – and offers a step-free access across the railway via a footbridge with lifts.

John Lawrie Tubulars supplied over 1200mtrs in 140Nr. 273mm tubes for use as piling for the updated platform and over-track walkway, delivering a carbon emissions saving of 293.73te CO2e when compared to the production of new steel products in the process.
