Most high density buildings have underground parking structures which are exposed to harsh service conditions. Mostly constructed of reinforced concrete and steel, they are exposed to salt during winter resulting in corrosion and eventual deterioration. Recently, a great deal of attention has been given to the challenges posed by parking garage deterioration as a result of safety risks posed to the public.
PEG’s team of structural and building specialists has been at the forefront of engineering consultancy dealing with and solving problems of parking garage deterioration.
Parking garage problems pose complex challenges that require the expertise of trained and experienced professionals to solve. Decisions arrived at from the start of investigations through to design has direct bearing on the durability of the rehabilitation project. For example, the design team must raise and answer many questions before settling on a design solution such as:
- Selective repairs or wholesale repairs?
- Jack hammer removal or hydro demolition?
- Type of traffic bearing membrane to be applied to protect concrete?
These are some of the questions that must be raised during design. PEG has kept pace with modern technology thereby ensuring that recommended solutions are cost effective, durable and innovative.
- Failure investigation.
- Life cycle cost analysis.
- Condition surveys and preparation of reports.
- Testing (chain dragging test, half cell ion test etc).
- Preventative maintenance planning & report.
- Field installation monitoring.
- Parking structure rehabilitation alternative recommendations.
- Preparation of repair construction drawings and specifications.
- Contract administration.
- Tendering.
- Post construction warranty monitoring.
