Concrete – structures or structural components made by plain, reinforced or prestressed concrete, precast or in-situ, such as residential, commercial or retail buildings, stadia, transport facility buildings etc.

Steel – structures comprising pre-fabricated steel members erected and assembled on site, such as buildings with large open plan areas (i.e. offices, warehouses ), large roof structures, high-rise buildings, etc.

Masonry – traditional load bearing stone, brick and blockwork construction, commonly used in low rise buildings, heritage structures and chimneys.

Timber – typically found in modestly sized roof structures of residential and commercial buildings, but also in modern engineered timber buildings and sports facilities, as well as temporary structures.

Composites & other materials – carbon fibre-reinforced polymers (CFRP) for strengthening solutions, structural glass and others.

Concrete – concrete strength, adequacy of reinforcement, deflection, water ingress, cracking, corrosion, deterioration, settlement, creep, chemical attack, fire resistance, movement joints, precast concrete members, specification of materials.

Steel – member and connection failures, welds and bolts issues, deflection, buckling, footfall, machinery or wind-induced vibrations, fabrication and erection tolerances, fatigue, fire resistance, specification of materials.

Masonry – load capacity assessment, specification, cracking, movement joints, stability.

Timber – specification, bracing and stability, load capacity, deflection, connection design, vibration, joint detailing, durability, fire resistance.

Roles and responsibilities – duties of designers, contractors and sub-contactors, standard of skill and care and standard practice.

Code compliance –assessing compliance with codes of practice and building regulations.

Health and safety during construction works – investigating the root cause(s) of collapse or partial collapse of structure during construction works, H&S incidents, temporary works, construction sequence, scaffolding.

Workmanship – tolerances, construction defects.

Remedial works – assessing need for remedial works, adequacy of remedial schemes prepared by others, devising remedial solutions.

Superstructure – investigating the causes of collapse or partial collapse, stability assessment, wind-induced damage, cracking, excessive deflection, concerns over the adequacy of design, concerns over the quality of workmanship.

Foundations – design, workmanship, excessive movement, cracking, material quantities, tolerances.

Basements – water ingress, heave, settlement, cracking.

Facades – assessing structural systems, fixings, wind induced damage, responsibilities.
