Top 10 Questions to Ask Your Civil Engineer Before Starting a Project

1. What ground conditions need to be considered before construction begins?

Civil engineers typically assess superficial geology (subsoil), bedrock geology, groundwater, land gases, contamination, vegetation, services, and historical land use. This informs foundation design, drainage strategies, and earthworks. Site investigations and geotechnical reports are often required.

2. Can cut and fill analysis help balance site levels?

Yes. Grading optimisation tools, including generative design, to reduce excavation, haulage, and import/export costs by balancing earthworks across the site.

3. How is surface water be managed to meet planning requirements?

Sustainable drainage systems (SuDS) are designed to manage runoff in line with local authority and Environment Agency guidelines. These reduce flood risk and support planning approval, following the drainage hierarchy: infiltration systems (soakaways), watercourses, surface water sewers, and finally combined sewers.

4. What does compliance with Section 278 or 104 agreements involve?

Civil engineers prepare designs for highway modifications and drainage schemes that meet adoption standards and legal agreements with local authorities or utility companies. (Section 278 or 104 agreements)

5. How are utilities and services coordinated on constrained sites?

Engineers plan around existing utilities and design coordinated trench layouts to avoid clashes with structures, roads, and landscaping features.

6. What approaches help reduce the carbon impact of infrastructure?

Common strategies include specifying low-carbon materials, optimising earthworks to reduce haulage, and incorporating SuDS and permeable surfaces. Companies like Matrix Consulting Engineers are designing with the support of carbon calculators that help to quantify potential reductions.

7. Can civil engineers support planning submissions and technical approvals?

Yes. Typical support includes preparing Flood Risk Assessments, Coal Mining Risk Assessments, drainage strategies, and design drawings to accompany planning applications or satisfy planning conditions.

8. What software is used for civil design and modelling?

Widely used platforms include Civil 3D, InfoDrainage, PDS, Causeway FLOW, and Revit. These allow engineers to create 3D ground models, drainage networks, road profiles, and visualisations within a BIM-enabled environment.

9. Do civil engineers design temporary works for construction?

Yes. Temporary works may include haul roads, excavation supports, piling platforms, crane pads, façade retention schemes, and traffic management layouts to ensure safe and efficient site logistics.

10. How is coordination ensured between civil, structural, and architectural design?

Collaboration across disciplines is supported by shared models and designs within Common Data Environment. Following standards such as ISO 19650 helps reduce clashes and delays by promoting effective information management.
