We completed the piling, sub and superstructure for this mixed-use development in Islington, London. Substructure works included the demolition of the existing basement and construction of an insitu reinforced concrete single and double-storey basement. Superstructure works included construction of a 42-storey tower and five eight-storey blocks. The tower was constructed using a jumpform core, while the remaining eight-storey blocks comprise a precast solution. Using our in- house expertise, we could convert the original core designs to the five eight-storey blocks into twinwall (over 10,000m2); insitu slabs generally converted to lattice slabs (66,000m2 floor area); and Stairmaster stairs converted to precast.

The tank fills and empties by gravity, fed by a 1500mm diameter concrete inlet pipe and a 400mm diameter concrete outlet pipe. Our delivery methodology and secant pile offering provided; greater verticality when piling – exceeding targets of 1 in 120 and instead achieving 1 in 1,000, improved programme efficiency – saving six weeks on the critical programme through our inlet portal approach and a safer site – with only four operatives requiring eight days to install the VacFlush column roof.

DAVYHULME WASTEWATER TREATMENT WORKS

Sector:
Value:
£140m

Our robust, value-for-money solution for Davyhulme involved a commitment to complete construction by 2017, with final handover after optimisation in 2018. Works included installing a new process treatment stream, inlet works, channels, pipelines and distribution chambers to feed six primary settlement tanks, a ten-lane aeration plant and ten final settlement tanks.
A ‘best in class’ solution
In heavy rain, wastewater flows into Davyhulme can reach 30,000 litres per second, the equivalent of 90 tankers every minute. Despite this being UU’s biggest site, our solution – based on ‘best in class’ programme and project management, innovation (particularly in process design and delivery), world-leading wastewater design and performance optimisation – allowed it to remain operational throughout. It also supported UU’s core value of ‘driving innovation’. An £8m green energy scheme also provides bio-gas for electricity generation on site, as well as supplying ‘green’ gas to the national gas grid. This means that Davyhulme WwTW has net-zero operating costs and is power self-sufficient.

Value:
£107m

LiMA, a joint venture between Laing O’Rourke and Atkins was appointed in December 2017 as main contractor for the Blackburn Batch of projects which includes Blackburn WwTW, Darwen WwTW, Nabs Head Inlet Works and the Darwen Pipeline.

Delivering the project scope
Nabs Head inlet works: construction of two new 10,000m3 blind storm storage tanks, both 102m long by 34m wide. These are filled (at up to 3,000 l/s) from a new CSO pump station and emptied by gravity once there is sufficient capacity to pass the flows onto the main works at Blackburn WwTW. Blackburn WwTW: construction of a new inlet channel and 72,000m3 insitu concrete structure with Nerada aerobic granular biomass technology. The system treats crude sewage that has received preliminary treatment at Nabs Head and is developed to treat the full flow and peak load at the works, ie. a complete replacement and expansion of the existing wastewater treatment plant with a flow to full treatment (FTFT) of 3,000 l/s. The Nerada structure comprises six 12,000m3 reactors; two 800m3 sludge buffers; one 800m3 water level correction buffer; associated aeration and pumping equipment. A Blower building and pipe bridge were constructed to house five blowers with a pipework network to each Nerada cell. Scope also included construction of new; ferric dosing area, UV treatment plant, SAS plant, poly dosing, sludge holding tanks, drum thickeners, lamella area and permanent filter bank. Darwen WwTW: transfer flows under gravity into the adjacent Blackburn drainage catchment, ultimately receiving treatment at the new Blackburn WwTW. Storm water storage at Darwen was increased to 6000m3 by the refurbishment and conversion of existing storm water storage and what would have become redundant primary settlement tanks. The Darwen works now pass forward 517 l/s via the Darwen Transfer Pipeline.

Sector:
Water
Value:
£20m

The biggest infrastructure project ever undertaken by the UK water industry, this is a once-in-a-generation opportunity to make London’s sewerage network fit for the 21st century and beyond.

An enormous engineering feat
Delivering heavy civil engineering, tunneling and complex marine infrastructure on space-limited sites in a busy capital presents an array of logistical and environmental challenges. The main tunnel is a huge undertaking: approximately 25km long, with an internal
diameter of between 6.5m and 7.2m, equivalent to the width of three London buses. The depth of the tunnel is between 35m in west London and 65m in east London.
Constructing shafts and a river wall

Expanded constructed rotary bored secant piles and rotary bored piles for the construction of the two shafts and river wall as part of the Albert Embankment Foreshore Tideway Project. The interception chamber shaft located by the Vauxhall Bridge connects the exiting Clapham and Brixton sewer outlets and the 48m deep circular shaft, located in Cofferdam 1 in front of Camelford House, connects the main Tideway Tunnel built under the river Thames.

Extremely restricted site
This was a constrained site, with Cofferdam 2 isolated from any road supply for all deliveries. To overcome this all plant, piling equipment and steel reinforcement were delivered to site by barge and lifted into site, always considering the high and low tides of the river to schedule the deliveries.

Key facts
• Cofferdam 1: Installation of 66no. 1200mm diameter contiguous bored wall piles and a challenging 66Nr 1300mm diameter hard-hard secant piles 27m deep fully cased, allowing the excavation of the circular shaft.
• Cofferdam 2: Installation of 147no. 750mm diameter firmhard wall as part of the interception chamber as well as 17no. 750mm diameter bearing and tower crane piles.
• The total bored length on the project was just over 6000m requiring approximately 5500m3 of concrete.

Laing O’Rourke constructed this 13-storey block to provide 220,000ft2 of prime Grade A commercial office space in Glasgow city centre. Although the building was originally planned as an in situ post-tensioned concrete frame, we could influence the outcome such that almost all the superstructure is of manufactured – mostly precast concrete – components. Our methodology involved double-height columns with beams, hollowcore planks and a structural topping. Cores are a combination of in situ reinforced concrete and twinwall, while the facade includes polished precast concrete panels and glazed curtain walling. In terms of piling and groundworks, the top-down basement used plunge columns, eliminating the need for baseplates and holding- down bolts.
