Services
Building Structures
We provide structural design services for new build projects including steelwork, reinforced concrete, timber, and masonry constructions. Our engineers ensure compliance with building regulations while optimising cost-efficiency. Collaborating with architects and design teams, we deliver solutions for educational, healthcare, retail, and commercial developments across the North-West.
Refurbishments
Our team evaluates existing buildings' structural integrity to determine suitability for conversion or extension. We develop tailored solutions for property refurbishments, working with multidisciplinary teams to address unknown structural challenges. This service ensures historic buildings meet modern standards while preserving their architectural value through expert engineering analysis.
Drainage & SUDS Design
We design flood-resilient drainage systems incorporating soakaways, swales, and attenuation tanks. Our SuDS solutions comply with planning requirements while addressing climate change impacts on urban flooding. Using hydraulic modelling software, we create site-specific strategies that meet Local Planning Authority standards for both new developments and existing infrastructure modifications.
Highways & Car Parks
We engineer access roads, car parks, and hardstandings tailored to site conditions and traffic requirements. Our designs integrate with topographical surveys to optimise drainage and vehicle movement. We prepare specifications for Local Authority adoption through Section 38 and 106 agreements, ensuring compliance with highway regulations for commercial developments.
Foundations
We design foundation solutions ranging from strip footings to piled foundations based on geotechnical data. Collaborating with geotechnical engineers, we address challenges like weak soils and contaminated sites. Our retaining wall designs utilise masonry, concrete, and sheet piling to stabilise sloping sites, ensuring structural integrity for diverse construction projects.
