TEMPORARY TRAFFIC MANAGEMENT

Temporary Traffic Management

A Temporary Traffic Management (TTM) design is the organization, arrangement, guidance, and control of both stationary and moving traffic, including pedestrians, cyclists, and all types of vehicles, around a hazard or work site for the safety of both road workers and road users.

The objective of a Temporary Traffic Management (TTM) design is to minimize impacts and disruption to the existing road network (traffic flow and connectivity) during construction activities and most importantly identify and eliminate or mitigate road user and construction worker safety during this time.

A Temporary Traffic Management (TTM) design is developed in accordance with Austroads Guidelines and Austroads Supplements, Traffic Control at Work Sites Manual, Australian Standards, and government specifications (e.g. TfNSW G10 Traffic Management Specification).

OUR APPROACH

At D-TAL, we understand that each project is unique, presenting its own set of challenges and requirements. Our approach to Temporary Traffic Management (TTM) design combines road user safety, constructability, a commitment to our clients and ultimately end road user satisfaction. We follow a systematic process that ensures the development of safe, efficient, and durable road networks and connectivity.

We achieve this through the following design process.

Clearly define project objectives and expectations.

Collaboration with all project stakeholders, working directly with our clients.

Collection of data and relevant information to inform design development.

Identify risks and opportunities.

Clear, concise, and regular communication with project stakeholders.

Comply with D-TAL’s ISO9001 certified Quality Management Systems (QMS).

WHY D-TAL?

Safety-Driven Road Design Solutions

We understand the importance and prioritize road user safety and risk management. Our team of road design engineers are also accredited Road Safety Auditors who can provide valuable road safety engineering input during the design development stage. Our road designs apply the ‘So Far As Is Reasonably Practicable’ (SFAIRP) approach (WHS Act) and implement the hierarchy of control measures, if it is not reasonably practicable to eliminate risks to road user safety.

Expert Collaboration to Maximize Safety During Construction

Our team have extensive, proven experience collaborating and delivering directly with construction contractors during the construction phase of a project to ensure road user and worker safety, traffic network efficiency and construction program are all considered. We aim to provide a safe, balanced solution is achieved.

Versatile Road Design Engineering Team

Our team of road design engineers bring a diverse array of engineering expertise ranging from road safety engineering, road design, traffic engineering and construction, allowing the design team to assess projects from a variety of perspectives.

Efficient Initiatives for Road Users

We identify opportunities to minimize impacts to road users, minimize construction programs and changes to temporary traffic staging arrangements with the intention of delivering new works to the community as soon as possible.

Performance-Based Design

Ultimately, the key function of a road is to cater for the performance characteristics of its users (motorized or otherwise). This includes traffic operational efficiency, road user safety, overall project costs, future maintenance costs and community and environmental impacts. We understand and embrace our role as key influencers when providing design solutions to achieve performance-based design objectives.

Project: Sydney Fish Market Redevelopment Project

Date: 2023-2024

Client: Ferry Carrig & Multiplex

Project Value: $750M

Service: Temporary Traffic Management

P0088_SFM 1

Project Description:

The new Sydney Fish Market will be located at the head of Blackwattle Bay on Bridge Road, Glebe, within Blackwattle Bay. The site is adjacent to the existing fish market, located southeast of Anzac Bridge at the intersection of Pyrmont Bridge Road and the Western Distributor.

As part of the redevelopment, Temporary Traffic Management (TTM) traffic staging designs are required on Bridge Road to facilitate the construction of the permanent works. This includes utility and pavement works, to provide bus stopping areas on the streetscape of the redevelopment and an additional northern leg to an existing intersection at Wentworth Park Road, required to access the new Sydney Fish Market.

D-TAL was engaged to prepare the Traffic Management (TTM) design to support the proposed construction program, whilst minimizing traffic impacts to all road users during construction activities on Bridge Road.

Key roles and responsibilities:

Our scope of work included.

  • Temporary Traffic Management (TTM) Design (traffic staging and temporary roadworks)
  • 3D CAD design models and staging drawings.
  • Temporary signalised intersection design coordination (TCS plans).
  • Road safety barrier design.
  • Temporary road signage
  • Line marking and pavement marking design.
  • Vehicle turn path analysis.

Testimonial:

“We thoroughly enjoyed working with D-TAL to deliver the Temporary Traffic Management (TTM) designs for the Sydney Fish Market Redevelopment project. D-TAL provided professional advice and their design service exceeded expectations. They were able to meet program and critical milestones. I would highly recommend D-TAL for any civil engineering design services. “

Project: Singleton Bypass (Tender Design)

Date: 2023

Client: John Holland / TfNSW

Project Value: $140M

Service: Temporary Traffic Management

P0094_Singleton Bypass

Project Description:

The New England Highway is part of the inland Sydney to Brisbane National Land Transport Network and the primary route connecting the Upper Hunter with Maitland and Newcastle. The highway passes through the centre of Singleton and carries around 26,000 vehicles, including more than 3700 heavy vehicles, each day. Traffic volumes are predicted to increase in the next 25 years. The planned bypass of Singleton would improve the movement of freight and journeys for current and future traffic demands. The Singleton Bypass aims to improve traffic flow, travel times, and safety through Singleton town centre by reducing traffic including heavy freight.

Key roles and responsibilities:

  • Temporary Traffic Management (TTM) Design for tender submission.
  • Road safety barrier designs.
  • Temporary road signage.
  • Line marking and pavement marking design.
  • Earthworks design.
  • Vehicle turn path analysis.


Testimonial:

“I recently worked with Dan and the D-TAL team on the Singleton Bypass tender to deliver a Traffic Management (TTM) strategy and design solution. I found Dan and his team to be professional and reliable. Their knowledge of Austroads and TfNSW standards allowed the project team to identify feasible traffic staging solutions efficiently. Dan and his team were able to quickly adapt to design changes and delivery timeframes. I highly recommend D-TAL’s services.”

Testimonial

“I recently worked with Daniel from D-TAL on a large $1.4B Design and Construct Infrastructure Tender as part of the proposed Sydney M7-M12 upgrade. My role as civil lead was to develop construction methodologies for a complex 3-tier intersection with 8 on/off ramps. The tender period was extremely tight and as a result, created a high-pressure environment.

I worked with Daniel directly to verify the proposed construction methodology and produce Traffic Management (TTM) staging drawings for the tender submission. Daniel and the D-TAL team were excellent to work with. In a high-pressure environment often working remotely via Teams, we were able to produce a well-thought-out and validated temporary works staging for the tender.

Daniel is a great communicator and is fully aware of the design standards and client expectations for temporary traffic management. Daniel was able to quickly identify solutions for complex alignment issues and always met his deadlines.

This is the second time I have worked with Daniel and both times have been a very positive experience. Daniel is a dedicated professional with high drive. I would not hesitate to work with him again.”
