FROM EARLY IDEAS THROUGH TO DELIVERY
RISEN supports projects of different sizes across Marlborough, from wastewater upgrades for homeowners to subdivision planning and infrastructure design. These examples show our approach to civil engineering, wastewater, drainage, surveying and site development.
Our work starts with understanding your site and objectives. We investigate the constraints, assess the options and develop practical designs. Where you need wider support, we can review contractor pricing and manage the work through construction and handover.
Client names and identifying details are omitted where appropriate.
FEATURED PROJECTS
Subdivision Design & Infrastructure Planning
Early civil planning for a rural Blenheim subdivision, assessing access, drainage and services to establish a practical basis for detailed design.
Site Specific Flood Hazard Assessment
LiDAR terrain mapping, catchment analysis and site assessment for a rural subdivision. The findings informed building locations, floor levels and drainage requirements.
Septic to Public Sewer Connection
Survey and wastewater design for a Blenheim homeowner replacing an ageing septic system. Our role included Council approval support, contractor pricing review and construction planning.
Onsite Wastewater Consent Renewal
Inspection and assessment of an existing wastewater system in the Marlborough Sounds, including soil testing, environmental risk review and preparation of the consent renewal application.
MORE PROJECT EXPERIENCE
A broad range of civil engineering work
Our wider engineering experience covers residential sites, rural properties and infrastructure. The areas below complement the featured case studies.
Wastewater Treatment & Performance Reviews
Independent assessments of wastewater system performance, identifying where targeted improvements may extend the life of an existing system.
Catchment Analysis & Culvert Design
Catchment and flow assessments to inform culvert sizing, road drainage and practical stormwater design.
Stormwater & Overland Flow Assessments
Terrain and drainage assessments to identify flow paths, ponding areas and the implications for proposed development.
Residential Site Development
Civil design to bring building platforms, earthworks, access, drainage and services together for a residential site.
Roading & Vehicle Access
Road and driveway design, culverts and drainage to improve access to rural and residential properties.
Structural Condition & Repair Assessments
Inspections of existing structures to assess visible deterioration and identify appropriate repairs or further investigation.
Retaining & Site Support Works
Engineering advice for retaining walls, earthworks, drainage and access on sites with limited space or challenging levels.
Surveying & 3D Modelling
Topographical surveys and RTK drone mapping to produce ground models and reliable information for design and planning.
Drone Inspections
High resolution drone images of areas that are hard to reach, giving a clear record for inspections and maintenance planning.
Earthworks & Volume Assessments
Surveying and ground models to calculate earthworks and stockpile volumes, helping with contractor pricing and planning.
Engineering Investigations & Options Assessments
Site investigations and options assessments that consider technical requirements, cost and construction constraints to support informed decisions.
Construction Monitoring
Site visits, contractor coordination and checks against the design as construction progresses.
Project Management & Delivery
Engineering and project management support from investigation and design through contractor pricing, construction oversight and handover.
A secondary onsite wastewater treatment system was designed for challenging soil and site conditions, using dripline irrigation, sloping land application and landscaped planting to provide a practical, low-maintenance solution that works with the site.
RTK enabled drone surveying provided fast, accurate spoil volume calculations, giving the client confidence in quantities, pricing and removal planning.
