Greenfields or Brownfields? We take the project from inception through to completion.
Engineering documentation and reports needed for Resource Consents
Subdivisions and scheme plans
By using our state of the art 3-D modelling software, we can provide reasonably accurate estimates of earthworks volumes and accurate finished surface levels.
Earthworks (inclusive of volume calculations and erosion and sediment control)
Slip remediation and slip repairs
We use state of the art computer simulation software to back up our cost effective solutions for stormwater drainage to land development, subdivisions and residential builds.We also do capacity analysis, flood plain analysis and applications for new connections to public systems.
Stormwater mitigation designs, networking, overland flow paths, and analysis
Engineering plan approvals for stormwater connections or diversions
STORMWATER AND WASTEWATER
WJ can size all stormwater requirements for residential projects including detention and retention tanks, soakage pits and other disposal devices.
Our wastewater department can provide specifications and design for all on site wastewater systems required for residential projects. We can determine the best type of system and sizing of the disposal field which is ideal for your project.
We can also assist in the specification of domestic sewage pump stations and pressurised rising mains.
We are experts in site inspection and construction guidance. We are well versed on what the council requires to get your project complied. WJ uses the latest in application based technology to provide the best experience to the various project stakeholders, communicate what is holding up the process and push through the project. We can provide Producer Statement 4 (PS4) certification for:
Concrete pre-pour: steel checks for foundations, block walls, and cast in-situ concrete.
Structural beam, connection and bracing inspection.
We provide state of the art solutions to your on-site effluent treatment problems; upgrading existing systems and designing new installations. We also provide the full service for capacity analysis and applications for new connections to public sewer systems.
Sanitary sewer network systems designs
Engineering plan approvals for sanitary sewers
ROADING & DRIVEWAY ACCESSES
We are known for our in-house capacity to do minor traffic engineering work, inclusive of ROW designs which comply with the Auckland Unitary Plan, vehicle tracking assessments, and new accessway applications (major and minor).
Driveways and accesses designs
Road safety improvements and intersection upgrades
ENVIRONMENTAL IMPACT MITIGATION
Our mitigation designs include for earthworks, stormwater diversions and effluent disposal. Compliance with surface water quality control requirements are crucial to many of our projects and we pride ourselves in getting it right every time.
