Our Civil Engineering team deliver high-quality design, consenting and project management services.
Fraser Thomas stormwater services include integrated catchment management planning.
Our expertise also covers low impact, appropriate technology, stormwater solutions, water sensitive design, stormwater reticulation, treatment and disposal, watercourse infrastructure assessment surveys, flood assessments and modelling.
Fraser Thomas have specialist skills in on-site wastewater management (TP58), decentralised sewerage, system design, consenting and certification including cost effective upgrades of existing wastewater systems.
We have been at the forefront in the development of appropriate wastewater technology in New Zealand, including oxidation ponds, aerated lagoons, wetlands, irrigation of municipal effluent, milliscreens, and decentralised sewerage and are recognised for its innovation, cultural sensitivity and consultation skills in this area.
Any land development or construction involving earthworks (excavation, trenching, drilling etc.) or any land disturbing activities can result in the erosion of exposed surfaces and sedimentation within the receiving environment.
Fraser Thomas have experience in appropriate erosion and sediment controls (ESC) and operate and maintain ESC measures as part of any earthworks activities in compliance with the Resource Management Act 1991.
As part of rolling out the Auckland Unitary Plan (notified September 2013), Auckland Council has made available online maps to identify areas prone to flooding within the Auckland Region. On these maps you can see whether your property is affected by overland flowpaths or flooding. Many of these maps are based on a rapid flood hazard assessment approach and are generally conservative in nature.
Council may require you to undertake a flood assessment if you wish to develop your property and if your property is located within one of these flood hazard areas, or you may like to assess the risk of flooding to existing buildings on your property for your own peace of mind.
We have undertaken numerous flood assessments for private properties for these reasons. These assessments range from relatively simple projects (e.g. site inspection, runoff calculations and short letter report) to more sophisticated work (e.g. catchment management plan review, flood modelling), depending on the nature of the flood hazard.
Fraser Thomas have extensive experience in roading and pavement design both in New Zealand and Internationally. Our civil teams also undertake resource consenting, contract preparation and supervision.
All roading and pavement design works take into consideration:
