Key Challenges
Local procurement within a remote region
With the project being in a remote location, local suppliers and subcontractors were minimal, with machinery and material needing to be transported from other locations across NSW and Greater Sydney. Despite these challenges, Delaney Civil successfully sourced a local contractor for the additional machinery required, which also provided an opportunity for a local business to be involved in the project. The facilities of other local businesses were also engaged throughout the duration of the project, which further boosted the local economy. Whilst not being a local contractor, Delaney Civil successfully established strong working relationships with Bourke Shire Council, local service providers including waste management facilities, and the local community.
Successful programming for project delivery on time and under budget
Delaney Civil effectively programmed the works between the two construction sites on the Eastern and Western side of the bridge. Site was mobilised within a short time frame from project award, and there were two teams on site, with one team working and the second team preparing the works. Using their strong communication skills, the teams successfully communicated with each other to ensure there was no downtime. Utilising our in house resources, careful programming, practical and detailed methodology and daily toolbox talks on the sequences of works, Delaney Civil successfully avoided delays and maximised productivity and efficiency and delivered the project on time and under budget through minimisation of the provisional works.
Respecting local and Indigenous Heritage
Given the construction site was within 200m of the Darling River, it was identified as being a sensitive landscape for Aboriginal sites. Whilst no Aboriginal objects were recorded within the study area during the standard archaeological field survey, Delaney Civil outlined an area of sensitivity to preserve the Aboriginal area of significance near the work site. Delaney Civil also successfully completed the project in line with the heritage listing of the wrought iron structure, the project was completed with no damage to it and the completed project ensures it will be preserved for future use.
