Hatch’s Structural Remediation unit customises service levels to address the needs of our clients using cost-effective solutions.
Key capabilities:
- diagnostic investigation of concrete structures
- structural risk assessments
- prioritised structural audits and budget planning
- engineered structural solutions and documentation
- global, civil and structural audits
- diagnostic surveys
- repair solutions
- construction supervision
- concrete inspections
- cathodic protection
Our global audits are site inspections of all concrete and steel structures. We prioritise the facilities on the basis of their structural risk, operational security and occupational health and safety risk. Some areas of the plant may require a more substantive investigation, which is a ‘diagnostic survey’.
With a diagnostic survey, we collect the following:
- Drummy survey
- Core-and-powder samples analysis
- Schmidt hammer testing
- Reinforcement cover and location measurements
- Concrete crack monitoring
- Carbonation testing
- Chemical analysis
- Environmental assessments
- Structural assessments
- Structural performance
- Plant and equipment shutdowns
- Recommendations for repairs and modifications
A diagnostic survey ends in draft designs and documentation using the latest computer software with 3D capabilities. Repairs are cost effective and are undertaken during planned plant shutdowns.
Construction supervision and concrete mix designs ensure cost-effective repairs and minimize future repairs due to efficient QA/QC supervision. Our construction supervision ensures that the reinforcement, framework and concrete mix are in accordance with design drawings, all of which are critical to the future life of the structure. Repair recommendations include:
- repair existing structures to original strength
- Analyse structures and prepare engineering solutions
- Coating systems
- Cathodic protection systems
- Durable concrete mixes
- Incorporation of additives to improve durability and mix design
