Evaluation of Buildings and Structures for Heavy Industrial Plants 

Condition Assessment of Structural Components of an Industrial Process Plant

The structural condition assessment of buildings and structures of an industrial process plant is essential to the prevention of major problems involving the safety of the workforce, significant maintenance costs, environmental pollution, and production losses. A structural failure increases the risk of injury to plant personnel, and depending on the kind of structure and its function, it can lead to complete shutdown of the plant’s operations.  An evaluation prevents unexpected failures, provides a cost-effective solution to maintenance, reduces the risk of injury and life loss to plant personnel, puts the future operating time of the plant in condition of assured reliability, and it could increase the life of the plant’s equipment.

Services

The expanse of our services covers the following:

figure-1 evaluation-of-buildings-and-structures vehicular-impact-damage- Site visit to the Plant  to visually inspect the condition of buildings, silos and main structures which could present detected or undetected  structural problems, such as: cracks, delaminations, settlements, elements in risk to fall, vibrations, high corrosion, high deformations.

- Review in more detail the technical information of buildings and structures: Construction drawings, specifications, calculations and local codes.

- Perform material testing to certify the quality of the construction materials.

- Diagnose the problems and, in some cases, provide preliminary recommendations to reduce the risk of failure while a more deep analysis is underway.

- Prepare a techno-economical report indicating the cause(s) of the problem, alternatives and recommendations for the most appropriate solutions.

- Stability problems in buildings and structures.

- Overstressed Beams or Columns, which show high deformations

- High Vibrations in foundations for vibrating equipment

- Loads or conditions not considered in the original design

- Modifications made to structures without an analysis

PEC Consulting provides comprehensive structural evaluation of industrial processing facilities, both preventative and remedial. This service is offered by our highly- experienced, specialized consultants who will visit the plant, find the problems at incipient stages, prepare a comprehensive report which cause intervention prior to failure, and make sure that your problem is solved.
