Site: A556 Knutsford - Bowdon, Cheshire
Contractor: Costain
Client: Highways England
Products supplied: Precast concrete drainage and stormwater chamber systems
Work to improve the busy A556 trunk road between Knutsford and Bowdon in Cheshire by creating a new modern dual carriageway by-pass to the existing road has recently been completed. Highways England and their Tier 1 supplier Costain opened the new £192 million dual carriageway in March this year. The 7km road will carry some 51,000 vehicles a day and link the M6 at junction 19 to an improved junction 7 on the M56.
Helping Costain keep on track in delivering the road scheme on time, FP McCann has supplied a full range of precast concrete chamber systems manufactured in quality controlled factories and delivered to site as called off by the contracting team. In total some 750 precast concrete catch pits, Easi-Base units and flow control/penstock chambers have been delivered.
More than 600 DN1200 through to DN1800 diameter catchpits have been installed along the route. The pre-cored catchpit base design allows the contractor to quickly form an integral sealed sump system without the requirement for the delivery of wet trades such as ready mixed concrete and mortars. This means significantly less vehicle/person interface on site and the factory built units are more carbon and environment friendly as fuel and traffic movements are reduced.
Pipework can be quickly connected and the chamber rings placed on top to safely and efficiently complete the build. Using the 130mm wide wall manhole ring in conjunction with both the catchpit bases and Easi-Base units meant that the chambers didn’t have to be surrounded with concrete, increasing productivity on site and helping Costain under COSHH directives to minimise the exposure of operatives to a hazardous substance. As no powered saw cutting is required to form inlet/outlet points the precast chambers eliminate hand-arm vibration syndrome (HAVS) and there is no risk of airborne silica in any dust.
Over 100 Easi-Base units were also installed. Both the polypropylene lined DN1200 and monolithic DN1500 and DN1800 units are pre-benched and channelled again allowing for efficient and safe installation.
Commenting on the FP McCann chamber systems, Sean Ellison senior site agent for Costain said, “These off-site manufactured precast concrete chamber units have helped significantly in us achieving our build programme and on site safety targets. They are simple to install and the integrity of the finished sump and base units together with the benefits of the cast-in pipe openings and seals gives us the confidence that these precast concrete chambers will form part a long life, low maintenance drainage system on the A556 link road”.
Note: FP McCann’s offsite manufactured precast concrete drainage chamber systems have been accepted onto the Highways England project efficiencies register and shared through the HE Knowledge Bank Portal across other major highways infrastructure schemes.

A member of the wider design team with additional responsibility to support the box culvert technical team. The role has a dual responsibility; firstly, encompassing structural design and related issues for box culverts and associated products. Secondly, be part of the wider design team and technical team supporting other products in the F P McCann portfolio.
Leeds based ground worker and civil engineer, Athena Civil Engineering, has taken the initiative on a new housing development in Roundhay, near Leeds, to reduce the amount of primary aggregate used on the pipe drainage works. This is in line with industry guidelines which indicate that using a full surround class ‘S’ granular bedding in conjunction with large diameter precast concrete pipes is often over specifying the buried pipeline design.
Working on behalf of housing developer Chartford Homes at their new Hampton Park site, Athena has constructed a storm attenuation tank using FP McCann’s large diameter reinforced concrete spigot and socket pipes. By adopting a class ‘B’ embedment design, Athena has achieved significant cost savings and minimised environmental impact on site without sacrificing installed performance of the completed pipe system.
The attenuation tank set out in four pipe runs consists of 21 standard DN1800 2.5 metre spigot and socket pipes, 4 DN1800 pipes with end caps and 4 DN1800 pipes with end caps and cast in side entry access.
Using the Concrete Pipeline Systems Association (CPSA) structural design and material cost calculators based on BS 1295-1 “The structural design of buried pipelines”, Athena were able to determine the optimum bedding design to adopt for the project and calculate the cost benefits versus a plastic system with a full Class ‘S’ granular surround. Key inputs into the model included pipe sizes and comparative costs and imported granular material prices. Consideration was also given to the trench excavated material which was deemed suitable for final backfill purposes.
Commenting on the installation, Jonathan Hotham, Project Manager for Athena Civil Engineering said, “We had every intention of using plastic pipe on this project, but when FP McCann’s Area Manager, Igor Skoro, took us through the CPSA structural design and material cost calculators, it gave us the opportunity to present a more cost-effective and efficient approach to the job for our client and builder, Chartford Homes, who took on board our proposal. We shall certainly be using the CPSA material cost calculator on future schemes and a closer consideration of pipe choice, in conjunction with bedding options, will be something we’ll continue to develop.”

Site: Wooler, Northumberland
Client: Tarmac Ltd.
Products supplied: Precast concrete Easi-Bloc units and cable ducting
FP McCann has recently supplied its Easi-Bloc ‘Lego’ block unit and precast concrete cable ducts for a unique application at Tarmac’s Cheviot sand and gravel quarry in Wooler, Northumberland.
The washout water from the washing plant is being channelled down a run of 350x300x1000mm precast concrete ducts into a holding wedge pit which has been constructed using FP McCann’s 1200x600x450mm Easi-Bloc units. The pit measures approximately 10 metres long by 7 metres wide and is three blocks high (1.35 metres deep).
Normally supplied to utility projects for housing power and communication cables, the precast ducts are ideal as an open water channel and the blocks typically used for dry storage bays and small retaining walls, have proved they can perform as a low height water retention facility.
Commenting on the choice of products all supplied from FP McCann’s Alnwick precast factory, Gareth Williams, Cheviot Quarry Manager says, “In discussions with Graeme Convery, Production Supervisor at Alnwick, we jointly agreed that the precast cable duct/Easi-Bloc combination could provide a solution to channelling and holding the washout water from the plant. The scheme has been so successful that we are now looking at installing further precast channels to house water pipes from the plant that are currently buried and therefore difficult to access for maintenance purposes”.

FP McCann’s back-bolted caisson shaft segment rings have been used to build a 7.00m id waste water pump house at a new ‘super’ hospital development in the Gilly area of Charleroi, Belgium.
The construction of the water treatment plant is in advance of the building of the multi-million euro Grand Hospital du Charleroi which, on completion in 2022, will be one of the largest private healthcare facilities in southern Belgium.
The contract to build the shaft and other associated civil engineering works was awarded to one of Belgium’s leading infrastructure partners, construction company Sodraep S.A, by Dutch engineering management group Royal Haskoning DHV.
The shaft was sunk under its own weight using the caisson method with FP McCann’s 7.00m id back-bolted precast concrete rings forming the shaft wall. In total, 6 full loads of segments were delivered to the Gilly site.
Speaking on behalf of Sodraep S.A. Muriel Van Caenagem said, “The concrete segments supplied by FP McCann were connected on site and each ring descended under its own weight as the ground was excavated beneath. Once commissioned, this 9 metre deep chamber will receive wastewater from the new hospital in Charleroi. The pumps placed in the bottom of the tank will drive the water through to another catchment for further processing”.
FP McCann’s shaft segments are all factory-fitted with EPDM rubber gaskets which provide an immediate water-tight seal upon construction. Cross segment connections are made by passing a spear bolt through a pocket in one segment and screwing it into a threaded plastic socket in the adjacent segment. Circle joint connections are made using a ‘T’ bolt passing through a hole in one segment into a ‘T’ box in the adjacent segment. Bolts are designed to fully compress the gasket.
