Groundesign specialises in a range of design services for various aspects of geotechnical engineering, including strip, pad, raft and piled foundations, ground improvement, anchors, basements and retaining walls.
I will handle the design including waterproofing measures, reinforcement, temporary works, drainage and structural design.
I can design trench, strip, pad foundations, piled foundations & reinforced concrete rafts designed with finite element software.
Design of concrete as per BS8110, structural steel as per BS5950, design of walls as per BS5628 and timber design as per BS5268.
I carry out the design for a range of pile types from concrete CFA to bottom driven steel tubular piles, inc. analysis of laterally loaded piles & piles groups.
Designs for contiguous, secant, king-post, reinforced concrete, sheet piled and mass gravity walls are available.
Fixed quotes are available for design work. Quality controls are employed at every stage of the design process. A design document along with drawings are completed and delivered within an agreed time-frame.
Graduated with BEng Civil Engineering 2003 (Queen’s University Belfast). Completed PhD in Geophysics in 2006 (Queen’s University Belfast).
Many years of experience in engineering with practical design experience in geotechnical engineering for various projects including strip, pad, raft and piled foundations, ground improvement, anchors, basements and retaining walls.
A lot of care is taken to ensure that designs issued are of a high quality. This is achieved by carrying out a careful review of the site investigation, geotechnical design parameters, loading cases and design options.
Quality controls are employed at every stage of the design process to ensure calculations are always carefully checked before the release of any design document. In the unlikely event of a negligence claim the design services offered here are covered by professional indemnity cover.

See below examples of past design work I have carried out to get a better idea of what I am able to achieve for you. Click on a project to see more photos.
Proposed basement and dwelling development at 48 Hill Rise, Chalfont St. Peter. This structure was designed as a basement with a reinforced concrete structure up to ground and first floor levels. The basement walls were partially constructed up against the contiguous piles used for the temporary works. Reinforced concrete was used to achieve complex geometries as requested by the architect. In addition a combination of steel and timber was used to finish the structure up to roof level.
Proposed basement and dwelling development at Acre End House, Oxfordshire. This structure was designed as a basement with a combination of castellated steels, precast floor and cavity wall construction up to roof level. The basement was founded on limestone which allowed natural draining and therefore provided optimum conditions for basement design. The client was very particular to achieve passive house level insulation so the basement was founded on well-compacted foam glass material to rule out cold-bridging.
House annex basement and superstructure development with car park basement with over 500 m2 basement area in total. The basement was constructed from waterproof concrete, external membrane and internal cavity drainage (Type B, A and C waterproofing). Contiguous bored piles with shotcrete onto reinforced mesh was used. Shotcrete was used to prevent dissolution of fines. Anchor piles to resist hydrostatic pressure were constructed underneath basement slab. External French drainage was installed with 2 x pumping chambers, one at the northern and one at the southern end of the basement with additional pumps installed to handle surface water from car park and access ramp to car park.
Foundation design for a proposed pile & beam construction in Acacia Avenue, London. Calculations include finite element modelling of pile & beam system, pile location proposal, pile load calculation and design of reinforced concrete ground beam for shear and bending. Design was submitted included pile layout drawing with associated reinforcement detail along with bending schedule.
