Purpose

RISE assessors have a very long and broad experience of inspections and condition assessments of various concrete structures, masonries and mortars. We assess, among other things, damage caused by reinforcement corrosion, freeze thaw, fire, moisture and alkali silica reactions (ASR). In addition, we inspect structures that are suspected to contain aluminate cement.

Damage assessments and condition assessments are carried out with the help of visual inspections, non-destructive testing (Ground Penetrating Radar, ultrasound and cover layer measurements), sampling, laboratory testing with advanced equipment and microscopic analysis of cement-based materials to determine composition, quality control and cause of damage. The laboratory tests are supplemented if necessary with photography and examination of samples taken.

In all damage assessments it is important that the cause(s) are investigated and charted in a relevant way.

The assignments often also include the design of tender documentation, evaluation of tenders, contract with contractor, construction management and technical control including control responsibility according to the Swedish law PBL (KA = Kontrollansvarig in Swedish).

We also carry out calculations of the remaining service lifetime of buildings / facilities based on, for instance, damage assessments.

 

The most frequent facilities or parts of the constructions that need damage assessment or condition assessment are:

 

  • Facades
  • Wharves
  • Bathhouses
  • Garages
  • Parking decks
  • Balconies
  • Floors
  • Swimming pools
  • Dwelling houses
  • Courtyard decks
  • Sewage treatment plants
  • Drinking water treatment plants
  • Bridges and tunnels
  • Industrial facilities
  • Water Towers

Method

RISE assess the condition of concrete structures, usually through visual inspections, damage surveying (scope and type), measurements, sampling and analysis.

Service

Inspection of garages and car parks

For several decades, RISE concrete assessors have inspected garages and car parks because they usually receive concrete damages. Most often, the damages are caused by chlorides from thawing salt, which is taken in with the cars during winter time. The chlorides penetrate the concrete and eventually cause the reinforcement to rust.
Fire safety / Expertise

Fire damage assessment of concrete

After fires, qualified fire assessment are needed to determine the condition of structures and the need for renovation. RISE has competent assessors who can examine concrete structures that have been damaged in fires. RISE has inspected several different fire-damaged structures including garages, residential buildings and industrial facilities.
