Scope
The scope of work included:
- 25,000m3 of bulk earthworks exported from site
- 11,000m3 of bulk earthworks cut-to-fill
- construction of 4510m2 of new road pavements including imported subgrade replacement
- provision of streetlighting along constructed roadway
- 392 metres of water reticulation
- 479 metres of sewer reticulation
- 610 metres of stormwater drainage
- provision of two detention basins within the low point of the site
- landscaping to the kerb including feature fig trees.
Outcomes
Upon commencement of works, the watermain design was revised which led to delayed construction approvals. To keep the project on schedule, BMD reversed the original construction program, starting on road pavement works while awaiting watermain approvals.
BMD updated the program to construct road drainage gullies up to grate level prior to placing pavement gravel. This eliminated the requirement for re-works and reduced programming pressure on the roadworks activity.
BMD worked collaboratively with the client, designers and subcontractors to manage a redesign of the retaining wall and corresponding earthworks. This was to account for an increased live load capacity, while still keeping within the tight project schedule and budget constraints.
