Coastal and Ports

Variables in the coastal and port engineering equation are complex. The environment is delicate, but also hostile and destructive. Work in this area requires balance and a particular level of expertise. At Tonkin & Taylor we provide that balance and skill set.

Our multi-disciplinary, specialist team of scientists, engineers and planners has an international track record. Our expertise provides appropriate solutions to coastal projects, statutory consents and engineering issues. That means security. Your project will be handled methodically and comprehensively, from feasibility assessment through consents, design and construction to rehabilitation and environmental monitoring.

We tailor our services to suit client requirements. Typical services include:
Planning – Coastal hazard mapping, preparation of statutory plans, integrated coastal zone management, port master plans, peer reviews, expert evidence and submissions.
Investigations – Field investigations, coastal process assessments, study of coastal impact effects, hazard assessments, numerical modelling, laboratory testing and analysis.
Monitoring – Shoreline movement, coastal process, sea state and water quality measurements.
Consents – Consultation, achieving compliance with environmental legislation, assessment and auditing of environmental effects and expert evidence.
Design and construction – Feasibility studies, value engineering, detailed design and supervision or maritime structures and protection works.

Experience
Coastal Hazard Identification and Management – We have carried out coastal erosion and inundation assessments for individual areas as well as entire regions, covering 100’s of kilometres. These studies involve a range of investigative techniques and GIS mapping tailored to our clients needs and budget, and require consideration of existing hazards as well as climate change effects. Many studies include development of appropriate mitigation, either using planning tools or physical works.

Oriental Bay Foreshore Restoration – Preliminary and detailed design of a multi award winning $7.5m foreshore restoration. The upgrade involved bringing in more than 22,000 tonnes of sand, building sand control reefs, and adding a wave platform, a pier, new toilet and changing facilities, a new playground, access steps down to the beach, and at-sea stormwater outlets to prevent the sand from washing into the sea. The beach's total sand area is now four times larger than before.

The project has won the following awards:
NZ Institute of Architects Urban Design award, 2004
NZ Institute of Landscape Architects George Malcolm Supreme Award, 2004
NZ Recreation Association Outstanding Project Award, 2004
NZ Contractors Federation Caltex Construction Award, 2004
International Federation of Landscape Architects Excellence Award, 2004
Association of Consulting Engineers NZ Gold Award of Excellence, 2005
Wellington Civil Trust Award, 2005
NZ Year of the Built Environment Award winner, 2005
NZ Institute of Architects Supreme Award, 2006.
Westport – Port Klang, MalaysiaWestport is Malaysia’s leading private seaport is located at Port Klang on its west coast. It handled 2.91 million TEU’s in 2005 and anticipates more than 3.4 million TEU’s in 2006. Due to significant growth as well as an increasingly important transhipment market, shipping volume is increasing significantly requiring major growth of this facility. T&T were engaged to provided detailed design of maritime and geotechnical aspects of a 4 km port and wharf extension, including eight new container terminals, dredging and reclamation.

Coastal ManagementManaging coastal erosion in a cost effective and sustainable manner that improves natural character and public amenity is the holy grail of many local authorities. T&T has been involved in many such coastal erosion assessments and satisfactory design and planning solutions, ranging from dune management and replanting, beach nourishment, bio-engineering as well as the more traditional protection methods, often combining beach nourishment and/or vegetation buffers with structural controls to improve the stability of the protection system.
