Atkinson Avenue Corridor Improvements

2021/2022 Auckland Transport Safety Improvements Programme

The Atkinson Avenue Corridor Improvements Project was part of the 2021/2022 Auckland Transport Safety Improvements Programme for providing safe pedestrian crossing facilities and managing excessive speed on this busy urban arterial. This $3M project included the construction of new pedestrian crossings across and along Atkinson Ave, improvements to three signalised intersections and the installation of asphalt speed tables on Atkinson Ave and its side streets. Construction of these improvements commenced in April 2022 and was completed in December 2022.

Bartley Consultants were involved as the construction engineers managing the construction contract and providing specialised advice on the asphalt speed table construction over the road pavement in marginal conditions. In conjunction with Auckland Transport and the Contractor Fulton Hogan, the project was implemented successfully under budget, with value added by improving existing pavement conditions over the intersections as a result of the speed table works. The learnings from this project were also applied to the other asphalt speed table works in various safety projects Auckland wide.

Waiheke Island Pavement Rehabilitation Projects

Annual programme of works on the Hauraki Gulf Islands

Bartley Consultants partnered with Opus International Consultants from 2008 to 2012 to deliver the professional services for Auckland Transports annual programme of works on the Hauraki Gulf Islands. This work comprised all of the investigation, design and monitoring required to ensure that the Roading, Drainage and Structures major maintenance and renewal programmes of work were delivered on time, to cost and to a consistently high standard.

On Waiheke Island, the roading component of work typically involved widening and strengthening existing road pavements, which are no longer providing a suitable level of service, to cater for future traffic demands and to meet the needs of cyclists and pedestrians. Many of the roads needed to be widened with footpaths provided and this often required the construction of retaining walls to support the increased formation width. In coastal areas it was also common for additional road side parking to be provided. In total, Bartley Consultants were involved in delivering the annual roading programme of works on Waiheke Island from 2006 to 2012. Some of the more significant roading projects included:

Alfred Street Upgrade

One-way road uprade between Princes Street and Symonds Street

Alfred Street is a one-way road that runs between Princes Street and Symonds Street in the heart of Auckland University. Bartley Consultants and the Auckland Road Maintenance Alliance consortium of MWH, Leightons and Blacktop Construction were tasked with upgrading Alfred Street to address concerns about the condition of the road pavement, road drainage and pedestrian facilities. This all needed to be achieved working in close proximity to a significant number of protected street trees that line each side of the street.

Bartley Consultants were responsible for developing a road pavement design that would achieve a 25 year design life, a geometric design that allowed the road level to be raised (thus minimising excavation near the trees), a paving design for the footpath areas, and drainage improvements to reduce surface water issues.

This project, which was implemented in early 2011, has significantly improved the quality and amenity value of this section of road.

Mt Roskill Motorway Extension SH20

Another key link in the western ring route

The State Highway 20 Mt Roskill Extension project was completed in May 2009. This project, which creates another key link in the western ring route, involved extending the Southwestern Motorway 4.5km from Queenstown Road in Hillsborough through Mt Roskill to Maioro Street in New Windsor. Two new interchanges were constructed at Hillsborough Road and Dominion Road and a new roundabout was constructed where the motorway intersected Sandringham Road. Four new overbridges were constructed to separate local road traffic from the motorway traffic.

Bartley Consultants were part of the URS lead design team for this project carrying out the pavement design of the main motorway alignment, ramps and local roads. One of the main challenges for this project was associated with the extremely variable ground conditions which ranged from alluvium to Waitemata Series clayey silts, siltstones and sandstones, tuff, scoria and solid basalt rock.

Takanini Road Widening & Pavement Rehabilitation

Widening sealed road pavements to incorporate gobi block paving areas.

Bartley Consultants Ltd were commissioned by the former Papakura District Council in 2006 to inspect a number of roads in the Takanini area where Gobi blocks have been used to provide parking adjacent to the main carriageway. The Gobi blocks were laid adjacent to the sealed pavement in selected streets in the Takanini area some 20 to 30 years ago. They were provided so that water flowing from the sealed road surface could flow into or over the Gobi block paving. Surplus water could then flow on to the grass verge which was shaped to provide a shallow swale discharging to centrally placed catchpits.

Over time the condition of the gobi block paving and adjacent grass verge areas had deteriorated to a point where the road side was unsightly, significant surface water ponding was occurring and the gobi block paving had become almost impermeable.

Bartley Consultants were tasked with widening the sealed road pavements, to incorporate the gobi block paving areas. In addition to designing the widening of the road pavements to cater for the traffic and parking demands, the roads were strengthened and drainage measures installed to ensure that the ground water levels continued to be recharged even with the increase in impervious area. The improvement generally extended from boundary to boundary and included the upgrade of pedestrian facilities.

This work was progressively implemented in Manuroa Road, Station Road, Princes Street, Le Havre Place and Takanini School Road between 2009 and 2012.

Fred Thomas Drive Pavement Rehabilitation, Takapuna

Upgrade of Fred Thomas Drive from Takapuna Landing to Anzac Street

Fred Thomas Drive was upgraded in late 2006 in conjunction with the New Zealand Transport Agencies Northern Busway Project. Bartley Consultants were commissioned by the former North Shore City Council to design the upgrade of Fred Thomas Drive from Takapuna Landing to Anzac Street. The design incorporated a southbound bus lane, on-road and off-road cycle lanes, improved pedestrian facilities and improved road drainage.

One of the challenges with this site was designing a pavement which wouldn't be significantly affected as a result of the ongoing settlement of landfill materials which underlie the road pavement. The pavement design incorporated a foamed bitumen base, which was a relatively new stabilisation treatment at the time, to provide a robust yet flexible base. The stabilisation treatment also helped to avoid any discontinuity of pavement materials and performance at the interface between the existing pavement and new widening.

Mulberry Grove Flood Mitigation, Great Barrier Island

Stormwater analysis for catchment area

Bartley Consultants were commissioned by the former Auckland City Council to investigate flooding occurring at Mulberry Grove School, Great Barrier Island. The flooding occurred whenever the adjacent stream exceeded the capacity of the road culverts and the road was overtopped. The flooding extended into the carpark area of the adjacent school.

Bartley Consultants carried out a stormwater analysis for the catchment area upstream of the road culverts in accordance with the former ARC document TP108. The US Army of Corps Hydraulic Engineering Centre (HEC) Hydraulic Modelling System (HMS) and River Analysis System (RAS) software was used to model the existing stormwater flows, determine the capacity of the existing culverts and to model potential flood mitigation options.

A number of flood mitigation options were assessed and in conjunction with Auckland City Council a decision was made to install a new 2.5m wide by 1.5m high box culvert next to the existing box culverts. Bartley Consultants prepared the supporting design documentation required for the resource and building consent applications. Construction drawings were also prepared and the implementation of the works was supervised by one of Bartley Consultants experienced site engineers. One of the main challenges on this project involved keeping the road open during the construction of the culvert. This required a collaborative approach, between our site engineer and the road maintenance contractor on Great Barrier Island, in order to find workable solutions using locally available resources. The work was completed in 2010.
