Beta Design Consultants have expert knowledge in the structural assessment of all types of building structures. We have provided advice to Clients of all sizes including:
- Homeowners and homebuyers seeking advice on housing defects (cracking, subsidence, illegal alterations).
- Listed and Historic Buildings during upgrade, repair and maintenance.
- Industrial Plants during shutdown and maintenance or during structural alterations, defects diagnosis and upgrades feasibility.
- Complex Offshore Structures and Oil and Gas facilities for maintenance, modification and life extension
We have expertise in diagnosing and specifying repairs and remedial actions for the following types of defects:
- Masonry buildings defects such as movement cracks, walls bulging, roof spread, roof sagging, failure of arches and lintels.
- Masonry buildings subsidence and foundation-ground related movement (including heave and shrinkage of clay soils, differential settlement of foundations, landslides and slope instability).
- Steel structures corrosion, excessive deflections, vibration and geometrical distortion locally and globally.
- Concrete buildings cracking, reinforcement bars corrosion, loss of alkalinity, chloride attack and concrete carbonation.
- Leaks in earth/water retaining structures and basements built in masonry retaining walls, concrete retaining walls and gravity concrete walls.
- Timber structures decay, excessive deflections (sagging and lateral distortion), roof spread and vibration.
We have conducted structural condition assessments for scores of industrial buildings including chemical plants, open process structures, equipment supports structures, skid foundations, equipment shelters, access structures, pipe supporting racks, heavy equipment foundations and underground structures (e.g. sumps, culverts, abutments, retaining walls).
Our scope usually includes the following services:
- A site survey to establish the current condition.
- A desk study to review existing documentation and as built drawings.
- Preparing a scope for further investigation if required (e.g. NDT testing, coring, soil investigation).
- Preparing a digital model if one does not exist.
- Allowing for structural alterations and deterioration of members and connections (e.g. corrosion, carbonation of concrete, loss of rebar section).
- Reviewing current loading based on client requirements, potential changes of use, applicable regulatory requirement.
- Advising the client of required actions including upgrades, repairs, maintenance and monitoring. This usually considers shutdown impact, safety, execution during operation, access constraints and construction method.
- Preparing reports to support the decision making process to manage risks and control budgets.
