Bus Bay Construction Mount Druitt

Project Overview 

Civil Environmental Services delivered the end-to- end construction of a new westbound bus bay on Woodstock Avenue, Mt Druitt, for Transport for NSW’s River-Zone program. This project aimed to enhance commuter access and safety along a high-traffic corridor.  The works included excavation, pavement reconstruction, kerb realignment, drainage,and installation of a 25 MPa reinforced concrete bus-stop slab. All works were completed under live traffic with strict compliance to TfNSW standards, ensuring a smooth tie-in to existing infrastructure and zero impact on the surrounding community.

Scope of Work

Pavement Construction — Pavement works involved site clearing, erosion control, NDD service verification, and saw cutting of existing pavement. After excavation to design level, we completed subgrade compaction and proof rolling, then placed a 300mm cementitious sub-base (SMZ M209). This was followed by a sprayed bitumen seal, a 225mm AC20 asphalt base (C450 binder), and an AC14 asphalt wearing course (A15E binder). The existing westbound lane was milled and resurfaced to tie in seamlessly with the new works.

‍Kerb and Channel Works — We constructed SB and SM kerbs with smooth transitions, using hand-pour methods and fully compliant formwork per TfNSW R53. This included accurate set-out, subgrade compaction, and installation of all temporary and permanent formwork. Our team handled blockouts, recesses, joint forming, and removal processes carefully to deliver a clean finish without the need for grinding.

‍Bus Stop Hardstand (Type P1 Slab) — Construction of the bus-stop slab included excavation, placement of a 120mm Class 2 DGB sub-base, and installation of HDPE sheeting. We poured 25 MPa reinforced concrete with SL72 mesh (R54 spec) and ensured a high-quality surface finish backed by thorough QA testing.

‍Street furniture & QA — The project concluded with installation of signage, line marking, and restoration of all disturbed areas.

Key Achievements

• ‍Completed all critical pavement and concrete pours during night-shift ROLs, keeping peak-hour traffic flowing and eliminating commuter disruption
• ‍Zero safety or environmental incidents despite constrained work- zones, multiple mobilisations and inclement-weather shifts
• ‍Met every TfNSW specification first time right, with full QA documentation and as-built survey handed over ahead of the March 2025 practical-completion target
