Structural Engineering Designs of Propping System

Structural Design

Design Engineering has provided structural engineering consultancy services for the part or whole demolition of various buildings (residential and commercial) in the Perth Metropolitan Region.

Design provided efficient engineering design solutions for the assessment of existing suspended slabs for the use of plant and equipment to perform the demolition works. This includes traditional reinforced slabs, pretensioned slabs and precast decking systems. Engineering checks were performed on adjacent structures to design  efficient propping system to maintain their stability and functionality during demolition works. Challenges overcome included analysing old buildings without structural drawings and limited client budget.

Design worked with Delta group to develop the most efficient demolition strategy with minimal propping while remaining on schedule.

Project Brief

Outcome

Prepared structural engineering designs of propping requirements to support existing buildings during demolition works.

Background

Design provides efficient engineering design solutions for the assessment of existing suspended slabs for the use of plant and equipment to perform the demolition works. This includes traditional reinforced slabs, pretensioned slabs and precast decking systems.

Engineering checks are performed on existing structures to remain stable and functional during demolition works to suit clients objectives.

Engineering design of an efficient propping system to support existing structures during the works and up until the future tie-in is completed.

Challenges

The clients generally have a limited budget for the projects and so we work together with Delta Group to provide the most efficient propping solution.

The analysis of existing slabs can be challenging if there are no structural drawings available or if the structure is old. Core holes can be used to determine the concrete depth, layout and sizing of reinforcing bars required to perform the analysis.

Demolition works adjacent to existing buildings requires careful planning and the methodology to prevent damage to nearby buildings which are to remain.

Our Approach

Based on the client’s requirements, Design works with Delta Group to develop the most efficient demolition methodology which provides minimal propping and reduction in time delays to ensure projects remain on schedule.
