Basement Design

I will handle the design including advice on site investigation required, design for waterproof concrete to BS8102 considering Type A, B and C waterproofing protection measures, design of appropriate reinforcement for waterproof concrete thermal cracking, design of temporary works to satisfy party wall engineer, design of external drainage and structural design for buoyancy amongst other aspects.

Comprehensive load 'take-down' of superstructure

Buoyancy risk assessment

Construction cost savings through value-engineered approach

Finite element modelling of basement slab / soil system using a layered soil model

Design of waterproof concrete retaining wall and slab for shear, bending and deflection

Detailed analysis of wall / slab interaction using a plane-frame model

Reinforced concrete drawings with bending schedule based on results of all analyses

Underpinning design if required for constructing basement walls flush against existing buildings

Foundation Design

I can design trench, strip, pad foundations and piled foundations (pile & beam, pile & raft and pile caps) and reinforced concrete rafts designed with finite element software. Also assessement of short term and long term settlements.

Piled foundations

Pile & beam

Pile & raft

Pile caps

Continuous reinforced concrete raft

Slabs designed with finite element software

Calculation of shear, bending moment and settlement distributions

Structural Engineering

Design of the core standards; concrete as per BS8110, structural steel as per BS5950, design of walls as per BS5628 and timber design as per BS5268. Additional standards followed are BS 6399 for building loadings, BS 8102 for basement waterproofing, BS 8103 for low rise buildings, BS 8500 for concrete design, BS8081 for ground anchorages and many more related standards.

Bearing, buckling and lateral capacity checks for walls

Wind load calculations

Roof timber design

General steel structures

Base plate designs

Roof cranked steel frames

Steel beam and column design (simple construction / sway frame)

Bearing Pile Design

I can carry out the design for a range of pile types from concrete CFA to bottom driven steel tubular piles including analysis of laterally loaded piles and piles groups.

Bored CFA

Bored open hole

Bottom driven with drop-hammer

Bottom driven with mole

Predicted settlement calculations for piles bearing on cohesive / granular soil or rock

Limiting lateral pressure in cohesive / granular soils

Calculation of pile buckling capacity

Design of piling platform for rigs

Retaining Wall Design

Designs for contiguous, secant, king-post, reinforced concrete, sheet piled and mass gravity walls are available. Designs are carried out according to guidance in CIRIA R104 for piles embedded in stiff clay and CIRIA C580 for embedded retaining walls. Designs are carried out in accordance to either EC7 eurocode or the British Standard BS8002.

Contiguous, secant, king-post, reinforced concrete, sheet piled and mass gravity walls

Stability analysis, reinforcement design and serviceability analysis

Modelling of surcharges including adjacent buildings, embankments, adjacent roads and highways

Design of props considering buckling capacity, stiffness, thrust block design and bracing systems and analysis of construction stages to optimise for prop locations and reinforcement required

Design for capping beam if required
