Concrete Restoration & Rehabilitation Engineering
Construction Durability Engineers (CDE) provides extensive concrete restoration and rehabilitation engineering services, including the investigation and evaluation of existing structures, design of remedial measures, and quality control monitoring during restoration projects.
We advise on various repair and rehabilitation strategies and help Client to determine the best fit to their assets based on required service life. Our integrated service offering means we have the capability to assist throughout the entire remediation process, from inspection, testing and diagnosis to remediation design, drafting, tender documentation and provide onsite engineering and supervision of the concrete repair work.
Investigations/Evaluations of Existing Structures
CDE restoration specialists identify and evaluate the condition of various components in existing facilities, using innovative testing methods to enhance traditional investigation.
A correct diagnosis establishing the cause, nature and extent of damage, and the weakness or deterioration caused in the structure is very essential, since a faulty diagnosis may lead to improper selection of materials and repair techniques leading to the failure of the repaired zone again. It may also be necessary that the serviceability of the structure is checked after carrying out the necessary repairs.
A structural condition assessment is the process of collecting observations and data and systematically using them to evaluate and assess the condition of an existing structure. Structural condition assessment is the physical examination and diagnosis of the health of a structure.
CDE offers condition assessment on structures in a wide range of aggressive climatic conditions around the world, including; Buildings, Bridges, Tunnels, Ports, industrial Plants
We provide an overview of current condition of assets for corrective work to remedy the physical deficiencies in the written report for each property which includes:
- Visual Inspection Survey
- Review of available documents
- Field and Laboratory Testing
- Establish root cause of observed deterioration
- Provide recommendation for rectifications
Assessment & Repair Design of PT Structures
- Laying out field investigation
- Grouting check
- Analyzing PT structures with defects
- Laying out Repair details for strength and long term durability
- External and Internal Post-Tensioning
- Repair Specification
Repair Recommendation and Design
It has been estimated that 50 percent of repairs are not performing satisfactorily due to errors in design, construction and/or material selection. CDE helps in design and implement repairs of deficient elements that restore service life and property value.
To ensure the quality of repair works, Clients require comprehensive documentation that is complete with all the technical information needed to undertake remediation and construction to the required standard. Having experts with experience in repair, protection and refurbishment of structures, we help ensure that remediation projects deliver the outcome and service life you require. As consultants, we understand of Clients needs and, we design solutions that match durability and operation needs.
