Rapid Bottom Driven Piling & Ground Beams for Residential Project
Project Overview It’s a familiar scenario on residential developments — trench excavations are complete, only for the building inspector to determine that piling is required. With the project at risk of delay, Dawson Foundation Engineering (DFE) was contacted to provide a rapid, engineered solution. Thanks to DFE’s in-house design capability, the piled foundation scheme was designed and the required reinforcement detailed and ordered within hours of first contact. Scope of Works Within 48 hours, the DFE team mobilised to site and installed 8 No. 100mm diameter bottom-driven steel-cased piles to depths of up to 8.0 metres, providing a stable and compliant foundation solution for the proposed structure. The scope of works included: Rapid design of piled foundation solution Installation of bottom-driven steel-cased piles 100mm pile diameters to depths of 8.0m Supply and installation of Pecafil shuttering Construction of reinforced concrete ground beams Engineering & Delivery Following pile installation, DFE supplied and installed the Pecafil shuttering system before fixing the reinforcement and constructing the reinforced concrete ground beams. The concrete pour was completed in less than five working days from first contact, minimising disruption and allowing the client’s programme to resume without delay. This fast-track delivery was made possible by DFE’s integrated design-and-build approach, eliminating the need for external designers and reducing approval times. Quality & Performance The works were delivered efficiently, safely and in full compliance with Building Control requirements. The combination of rapid response, in-house engineering and experienced site teams ensured a high-quality outcome under significant time pressure. Our Expertise Dawson Foundation Engineering designs and installs a full range of piling services, including: Bottom-driven steel-cased piles Continuous Flight Auger (CFA) piles Sectional Flight Auger (SFA) piles ODEX piles Screw piles Ground beams, slabs and pile caps With proven experience in residential piling projects and time-critical foundations, DFE provides fast, reliable solutions when programmes are at risk.

ODEX Piling In Falkirk
Project Overview This week, the Dawson Foundation Engineering (DFE) team travelled north to Falkirk, Scotland, delivering specialist ODEX piling works on a constrained site with challenging ground conditions. The project involved the installation of 7 No. 220/190 ODEX piles, providing a robust and reliable foundation solution through variable strata. Ground Conditions & Pile Design The piles were advanced with casing to depths of up to 6.0 metres through weak mudstone and intact coal seams, before being socketed 3.0 metres into medium strong sandstone to achieve the required load capacity. All piles were reinforced throughout their full length and tremie grouted with neat cement, ensuring excellent structural performance and long-term durability. Engineering & Delivery All piling works were designed in house by DFE’s chartered engineer, allowing the team to tailor the pile design precisely to the site geology and loading requirements. The use of the ODEX system enabled safe and controlled installation through difficult ground conditions, minimising risk and maintaining programme efficiency throughout the works. Quality & Performance Despite the complex geology encountered, the works were completed efficiently and to a high standard, demonstrating DFE’s capability in delivering specialist piling solutions across the UK, including remote and logistically challenging locations. Our Expertise Dawson Foundation Engineering designs and installs a full range of piling services, including: Sectional Flight Auger (SFA) piles Continuous Flight Auger (CFA) piles Bottom-driven piles ODEX piles Screw piles Ground beams, slabs and pile caps With in-house design expertise and nationwide delivery capability, DFE provides reliable foundation solutions for a wide range of commercial piling projects.

CFA Bored Piling Works in Wigan
Project Overview This week, the Dawson Foundation Engineering (DFE) team completed specialist continuous flight auger (CFA) piling works in Wigan, installing 125 No. 300mm diameter CFA bored piles to depths of up to 7.0 metres. The piles were formed through stiff clay strata and socketed into mudstones of the Pennine Middle Coal Measures, providing a robust foundation solution suitable for the proposed development. Scope of Works DFE were appointed to undertake the design and installation of the CFA piles, along with the design of the working platform, ensuring safe operations and programme efficiency throughout the works. Key elements of the scope included: Installation of 125 No. CFA bored piles 300mm pile diameters to depths of 7.0m Piling through stiff clay and into mudstone bedrock Design of an economic working platform Efficient spoil and concrete management on site Engineering Approach & Equipment Selection Following a detailed review of ground conditions and access constraints, DFE selected the Klemm 709-3G piling rig as the optimal solution for the project. This rig was chosen to limit ground bearing pressures, enabling a more economical working platform design, while still allowing each pile to be installed in a single auger stroke. The use of the 709-3G, combined with a 7 cubic metre agitator, allowed for continuous concrete supply and efficient pile formation, maximising productivity across the site. Programme & Performance The carefully considered plant selection and in-house design input resulted in excellent on-site performance. The piling works were completed two days ahead of programme, delivering both time and cost benefits for the client. This outcome reflects the experience, coordination and professionalism of the DFE site and engineering teams. Our Expertise Dawson Foundation Engineering provides a full range of piling services, including: Continuous Flight Auger (CFA) piles Sectional Flight Auger (SFA) piles Bottom-driven piles ODEX piles Screw piles Associated reinforced concrete (R.C) works With in-house design expertise and a flexible delivery team, DFE consistently delivers efficient foundation solutions across a wide range of commercial piling projects.

Restricted-Headroom SFA Piling Works – Wilmslow
Project Overview This week, Dawson Foundation Engineering (DFE) successfully completed specialist piling works in Wilmslow, delivering sectional flight auger (SFA) piling with 300mm diameter bored piles within an existing structure. The project presented several technical challenges, most notably restricted headroom of just 3.0 metres in certain areas, requiring careful planning, specialist equipment and responsive engineering input. Scope of Works DFE was appointed to design and install SFA piles to depths of up to 10.0 metres, ensuring the foundations met both structural and programme requirements. All piles were installed internally, within a live building environment, demanding a high level of control, coordination and attention to health and safety typical of commercial piling works. Key elements of the works included: Installation of 300mm diameter SFA bored piles Piling to depths of up to 10.0m Working within severely restricted headroom using specialist low headroom piling solutions Use of site-batched grout for pile formation Installation of reinforcement cages to resist shear and tensile forces Engineering Challenges & Solutions During installation, ground obstructions were encountered at several original pile locations. Thanks to DFE’s in-house design team, pile layouts and design solutions were revised immediately, allowing works to continue without impacting programme or quality. This integrated design-and-delivery approach ensured: Minimal disruption to site activities Rapid resolution of unforeseen ground conditions Continued compliance with structural performance requirements Quality & Performance All piles were formed using controlled grouting techniques and reinforced as required to suit the applied loads. Working in confined internal conditions required precise execution, with specialist low-headroom piling rigs deployed to safely and efficiently deliver the works. The result was a robust foundation solution installed on time, despite the constraints imposed by the existing structure. Our Expertise Dawson Foundation Engineering designs and installs a full range of piling services, including: Continuous Flight Auger (CFA) piles Sectional Flight Auger (SFA) piles Bottom-driven piles ODEX piles Screw piles Associated reinforced concrete (R.C) works With in-house design expertise and a flexible delivery team, DFE is well positioned to overcome complex ground conditions, restricted access and challenging site environments.
