Basements

Basement projects need careful engineering from the earliest stage because ground movement, groundwater, party walls, construction sequencing and temporary works all influence the final design.

JMS supports architects, homeowners, developers and contractors with basement feasibility, structural calculations, retaining wall design, slab and wall details, temporary support considerations and coordination with the wider design team.

The team looks at how excavation affects the existing building, neighbouring structures, access, drainage and buildability. That early review helps avoid expensive changes once the project is already on site.

Outputs can include structural calculations, design drawings, sketches, technical notes and construction-stage support for safe, practical below-ground works.
