Evaluation & Management of Civil & Structural Infrastructure
Civil & Structural Infrastructure Condition Assessment
STRUCTURAL TECHNOLOGIES offers integrated solutions and assessment services for existing infrastructure evaluation. Our methodologies are applicable to any structure exposed to aggressive environments (airborne chlorides, below grade water intrusion, harsh temperatures, chemical attacks, etc.).
STRUCTURAL TECHNOLOGIES’ condition assessment services are comprehensive – offering a range of testing and deliverables based on the needs of the owner and the project. The objective of a comprehensive condition assessment is to identify the root cause of problems and the level of damage.
By incorporating the capabilities of our contracting companies and their experience working in industrial and power facilities, we can also provide alternative solutions – enhanced by constructability analysis to optimize repairs, lower costs and ensure proper phasing, safety and schedule. This collaboration also allows us to offer conceptual budget estimates as an optional service.
We Offer Three Levels of Assessment Services:
| Observation Report | Condition Survey | Condition Assessment | |
| Report Summary | Comprehensive visual appraisal that describes the observed problem area(s) | Documentation of the problem area(s) that quantifies the location and degree of the visible defects and conditions | Analysis of collected data, documentation of current conditions, extent of damage (if any), and root cause analysis. |
| Observed Deterioration | ✔ | ✔ | ✔ |
| Deterioration Quantities | ✔ | ✔ | |
| Data & Lab Analysis | ✔ | ||
| Root Cause Analysis | ✔ | ||
| Service-Life Modeling & Prediction | STRUCTURAL TECHNOLOGIES offers optional service-life modeling and durability analysis to predict the life of the structure with and without repair utilizing SIMCO´s STADIUM® | ||
