We are in ENR’s Top 250 International Contractors List!

We are proud to announce that we are in the “The Top 250 International Contractors List 2020” announced by Engineering News Record (ENR)!

Engineering News-Record (widely known as ENR) is an American weekly magazine that provides news, analysis, data and opinion for the construction industry worldwide. It is widely regarded as one of the construction industry’s most authoritative publications.

ENR annually ranks the largest contractors and design firms internationally.

The list classes firms from across a number of sectors, based on contracting revenue from projects outside of their home countries, measuring their presence in international commerce.

This is the first year that Bothar Group has been recognised and is a fantastic accomplishment. Congratulations to the Bothar team!

Bothar achieves a 200m drive with its AVN800XC

Bothar’s Herrenknecht AVN800XC has successfully completed the trenchless component of the O’Possum Creek Trunk Sewer Project in Springfield Lakes, Queensland, Australia.

The project entailed a 200m drive through challenging ground conditions whilst also traveling under a railway, highway and alongside an environmentally sensitive creek.

Congratulations to Ray Polzin and the team for accomplishing such a challenging drive.

Bothar’s TBM “Eco” resurfaces

Eco, the tunnel boring machine on the Gold Coast Seaway project we are delivering for John Holland / City of Gold Coast, has resurfaced from its 1385m subsea crossing underneath the Gold Coast Broadway.

This project involved the installation of 1385m of OD2500, ID2100 Reinforced Jacking Pipe from Quota Park, Biggera Waters to South Stradbroke Island.  As part of the scope of works, Bothar was also responsible for the temporary works design and construction of launch and retrieval shafts required for pipe jacking operations, as well as all other engineering design required for pipe jacking operations.

A big shout out to Kieran O’Connor, Project Manager, and the entire #Bothar Project Team for maintaining world class safety standards while delivering this essential project during this unprecedented time in the world.

Lockerbie Main Sewer Project

The #Bothar Team Australia are excited to be starting the Lockerbie Main Sewer Project, North Melbourne, Victoria for the Broadspectrum Jaydo Joint Venture (BRISJAY). As part of Yarra Valley Water’s sewer pipeline which will cater for growth between Donnybrook and Beveridge in Melbourne’s northern growth area, Bothar’s AVN1200 will travel 2.65km underground installing a DN1400 GRP pipe for this essential infrastructure upgrade.

Gold Coast Seaway Underway

Bothar have commenced the construction of the 1385m subsea crossing for the Gold Coast City Council in Queensland, Australia. The 2500mm OD reinforced concrete jacking carrier pipe will be utilised to convey a treated effluent discharge line to a reception shaft at South Stradbroke Island. The launch shaft is a 26m deep, 12.5m diameter secant piled construction and the reception shaft is a 7.5m diameter 26m deep pre-cast segmental sunk caisson. This sub sea crossing will be constructed underneath the seabed of an environmentally protected area of Moreton Bay, providing for its continuous use by the local community for boating, fishing and recreational activities.
