Civil, Structural and Forensic Engineering Services
Civil, Commercial & Domestic structural design including:
ISS Consulting provides civil and structural engineering advice for design, investigation, construction and remedial works. The services below cover both conventional design work and independent engineering investigations. Many instructions involve more than one discipline, for example where drainage, ground conditions, structural movement, construction sequence and workmanship all need to be considered together.
Cut and fill balance
We assess existing ground levels and topography to determine the most efficient earthworks strategy. This not only optimises finished floor levels and grading but reduces cut and fill movement, saving time and cost on site. Data from surveys and Civil 3D modelling ensures practical, constructible results
Drainage design
We produce compliant S104 and S106 drainage designs tailored to site constraints, ensuring surface and foul water systems are properly coordinated with structural and civil engineering elements of your project.
Foundation advice
Our foundation design advice is grounded in real construction conditions and can include arranging site investigations where appropriate. We interpret soils, recommend footing types, and check bearing capacity to ensure safe and efficient support for your structures.
Basement construction advice and structural design.
We provide structural design and technical guidance for basement elements, including interaction with surrounding ground and waterproofing strategy (with subconsultant support), helping you avoid common pitfalls in subterranean construction
Steel/Timber/Glulam/Flitch beams/columns
From traditional steel to engineered timber, glulam and flitch sections, we size and detail beams and columns to suit architectural intent. All designs consider constructability a loading conditions
Steel Portal frames
We design and check portal frames and metal trusses for industrial, agricultural and commercial buildings, ensuring structural stability and compliance with relevant codes.
Solar on existing roofs
Checks for solar photovoltaic (PV) installations on existing buildings ensure that roof structures can safely support additional panel loads and wind uplift. We verify load paths and roof capacity before installation.
ICF Walling and Structural Design
Insulated Concrete Formwork (ICF) systems offer thermal efficiency and speed on site. We provide structural design input for ICF walls, ensuring integration with other building elements and overall stability.
Timber design
From bespoke timber trusses and purlins to cut roofs and feature timber elements, we design structural timber components that are both elegant and effective, fully coordinating with roof and floor systems.
Timber and pre-cast concrete Floors.
Whether timber joists or precast concrete floors, we size and detail floor structures to handle imposed loads and integration with services, ensuring durability and performance.
Reinforced concrete design
We design reinforced concrete elements such as basements, retaining walls and ground beams, providing bending schedules and detailing suited to each project’s site conditions and loadings.
Wall stability calculations
For masonry, concrete and Insulated Concrete Formwork (ICF) walls, we calculate lateral loads, fixity conditions, and necessary reinforcement to ensure stability under service conditions.
Highways design
We provide S184 and S278 consultancy and design work for highway access, site entries, and road adoption requirements, coordinating civil and structural aspects within local authority standards.
Structural Engineers Reports
We prepare clear, professional structural engineering reports for domestic and commercial buildings, including Class Q conversions addressing stability, load paths, remedial recommendations and Building Control requirements.
Fire damage assessments
We assess structural condition after fire exposure and provide technical reports outlining damage mechanisms, residual capacities and repair recommendations where needed.
Geotechnical Engineering
We deliver practical geotechnical services integrated with our structural work, including:
- Foundation design and bearing capacity checks
- Ground investigation interpretation
- Shallow and deep foundation recommendations
- Retaining wall earth pressure analysis
- Slope stability and ground movement assessment
- Basement and below-ground structure interaction
- Soil-structure interaction advice
This ensures your structure truly suits the ground conditions encountered on site, not just on paper.
Drone surveys
High-resolution drone imaging coupled with structural assessment allows efficient visual inspection of roofs, facades, and complex or hard-to-reach areas, feeding directly into our reporting.
