Project Overview:
- Dutton Road upgrade to introduce new slip lane into the new Home Maker Centre
- Demolition of existing concrete bus bay and existing kerbing
- Profiling and excavating existing road to reach new design subgrade
- Excavating and installing new DIT stormwater pit and pipework
- Preparing and pouring new kerb and water table, median kerb, pram ramps and kerb infill to AS 3600
- Constructing new road with quarry pavement materials and hot mix asphalt to AS 2150
- All works performed under staged manner to maintain traffic flow, full time traffic control to AS 1744
- Portions of the works performed at night to ensure minimal disruption to traffic
Scope of Work:
Staging, Traffic Control and Stake Holders:
- Kalkan carried out meticulous planning before commencing this project. Various staging plans and traffic control plans were reviewed in detail. The project was divided into day works and night works to ensure that public and stakeholder safety was not compromised and to maintain traffic flow on Dutton Road. Six full-time traffic controllers were involved in the project’s peak, implementing stop-and-go and contra-flow methodologies.
Demolition:
- With the use of a hydraulic hammer attachment on our excavator Kalkan carefully executed the removal of 150mm thick concrete within the bus bay, also removed median kerbs and concrete islands. All works were performed in precise manner to ensure public safety was not compromised.
Profiling, Excavating and DIT Spec Stormwater:
- Kalkan had the task of constructing over 50 metres of roadway in short space of time. Kalkan adopted the DIT specification for the construction and installation of stormwater infrastructure, and used conventional methods of preparing base course beneath kerb and gutters. Following these works, Kalkan used a road profiler to excavate the main carriage down to underside of new asphalt course. We carried out the tasks by staging the works into 3 main stages and ensuring clear and concise communication was carried out through-out the process.
Challenges and Solutions:
- Constructing a road to DIT Spec amongst live traffic
- For this Kalkan meticulously planned and adopted various methods of traffic control implementation
- Project was broken down into 3 stages:
Stage 1: Day works was to install stormwater line and kerbing with contra-
flow traffic control setup
Stage 2: Day works was to install centre median kerb island with stop and
go traffic control setup
Stage 3: Dight works was profiling and main carriage asphalt works with
stop and go traffic control setup
Conclusion
The Mount Barker Homemaker Centre Road Works project was executed with meticulous planning and a strong focus on safety and quality. Dividing the project into stages allowed us to maintain traffic flow on Dutton Road, demonstrating our commitment to public safety. We followed strict specifications for stormwater infrastructure and demolition, ensuring precision at every step. This project’s success is a testament to our dedication to excellence and stakeholder satisfaction.
