STRUCTURAL ASSESSMENTS AND UPGRADE OF STRUCTURES, FORENSIC AND CORROSION ENGINEERING

S & F can obtain detailed internal construction and condition assessments of a variety of engineered structures including buildings, bridges, tunnels and roads. Together with targeted Non Destructive Testing, destructive testing, laboratory testing and visual inspection, a complete assessment of an engineered structure can be made.

S & F is a leading specialist structural investigation practice with the skills and resources in-house to provide preliminary structural assessment and feasibility advice; to design and specify structural investigations and to carry out a wide range of on-site testing, sampling and investigative techniques, including:

Structural inspection, investigation and Evaluation:

  • Structural inspections of all types of buildings and civil engineering structures including bridges, culverts, retaining walls, basements, dams, pipelines, water towers and tanks, shafts and tunnels
  • Non-destructive testing including cover meter surveys for reinforcement mapping, half-cell and resistivity surveys for reinforcement corrosion, measurement of depth of carbonation, radar surveys, rebound (Schmidt) hammer strength testing, BRE internal fracture testing, ultrasonic pulse velocity (UPV) testing, in situ permeability testing and waterproof membrane proof testing
  • Failure Investigations and analysis
  • Forensic Services and Structural Evaluation
  • Predictions of Service Life of structures

N.B. We are only investigators on testing extent of corrosion in R.C and Steel structures.

  • Construction detail / re-specification of concrete structures including reinforcement spacing, depth of cover and diameters, and concrete thickness and strength o Assessment of concrete condition including honey combing, delamination, voiding and reinforcement corrosion potential
  • Mapping of features within concrete structures including service conduits, poorly grouted PT ducts and void former positions
  • Assessment of internal condition of timber structures including bridges and power poles
  • Construction detail and condition within brick and concrete lined tunnels
  • Construction detail and condition of retaining structures including dams and retaining walls
  • Assessment of heritage structures
  • Pile / foundation testing

Corrosion testing is important in estimating the remained Service Life of structures, to plan for maintenance, control measures In Financial institution these tests are important to estimate the value of building as collateral. This technique is most likely to be used for assessment of the durability of reinforced concrete members where reinforcement corrosion is suspected. Reported uses include the location of areas of high reinforcement corrosion risk in marine structures, bulk storage tanks, bridge decks and abutments. Used in conjunction with other tests, it has been found helpful when investigating concrete contaminated by salts
