WE WORK ON A WIDE RANGE OF PROJECTS

Commercial, Residential, Infrastructure, Local Government

Our engineers, surveyors, planners and project managers thoroughly examine all options to identify the most robust and effective solutions for our clients.

With Envivo you can be sure your development plans are a success on every level.

We are excited by the new Google satellite imagery for the Auckland area. This new view of our largest city is only weeks old, we’ve created a short Google Earth Tour of some of the apartment sites we at Envivo are working on click here.  We have plenty more in progress…

Wineworks Development

WineWorks provides wine bottling, labelling, warehousing storage and distribution services to New Zealand wineries.  They invest in world-class technology, machinery and facilities.  We have been helping them develop their new site in Onehunga with a 1.6ha Building footprint.

Envivo surveyors provided the following services:

  • Topographic Survey
  • Redefinition Survey
  • Establishment of a new ROW Easement
  • As-builts including the innovative 3D laser scanning of the stormwater system
  • Construction Setout
  • Earthworks volumes Survey

We started with a Topographical Survey which is a map of the spatial features and contours of a site. We produced a richly detailed plan showing buildings, paved areas, services, spot heights, contours, easements and legal boundaries. This information is the critical first step for the architect and project manager.

We pride ourselves on the high accuracy of our surveys and this certainly proved useful on this project.  We were able to use the data collected earlier to calculate the cut-and-fill requirements for earthworks.  This saved the project time and money by using existing information and eliminating the need to re-survey the property.

One of the big questions was how to best maximise the site as there was an easement along western edge.  The architects needed to know how close to the boundary they could build and how much of the site they could cover.  Complicating matters were the large 1.5m diameter stormwater pipes,the 11,000v power cables and an inability to access critical manholes.  Our surveyors came up with some innovative solutions.  Usually a remote-control CCTV vehicle would be used to capture information such as depth and alignment.  This traditional approach failed due to electrical interference from the power cables.

The surveying team utilised our X330 Faro 3D Laser Scanner to investigate the 1.5 metre pipes.  The point cloud was modelled and 3D pipeline plans were sent to the architect and structural engineer, who were then able to factor in the exclusion zones to their drawings.

The construction also required extremely high accuracy setout of over 1500 points which ranged in accuracies of between ±5mm – ±1mm on the site.  The setout ensured that precast panels, columns and structural steel bolts could fit into their allocated slots like a giant jigsaw.  This was no small feat with 50 massive 17 metre high concrete columns that had to be lifted into place – each using two cranes.

Continuing on the theme of accuracy – the verticality of columns, naturally, had to be exceptionally precise.  This is because the structural beams were unusually long.  The structural beams span between two columns was 73 metres, with no mid-support.  A high-accuracy asbuilt was called for by the project manager and constructor.  We asbuilt surveyed each of the trusses separately, then held our breath as five cranes lifted each truss into place.

The set out survey was also unusual in that our surveyors were 17 metres in air.  With such large beams the bolts had to be millimetre accurate and this was technically challenging.  We had one surveyor on the ground as control and the other high in the cherry picker setting out points.

Once the beams were in place the surveyors undertook an asbuilt deflection survey.

Joe Leeper said “this was a thoroughly interesting project to work on from the outset.  I started working on it in mid-2014 and it’s great to see it all come together so smoothly.  A key concern for me was the tight timeframes for construction.  We had to fit in with schedule of other stakeholders such as the architect, project manager and structural engineers.

“I needed to be on top of what was going on; coordinating the timing and working closely with the project manager.  We made sure that a certain number of hours was allocated each week for this project, during a very busy time for all our surveying teams.  I was actively involved in coordinating the surveyors’ time and resources in-house, managing the field teams and ensuring the data reached the project manager when he needed it.

“I learnt a huge amount about quality control; just one mark in the wrong place could potentially cost the client hundreds of thousands of dollars.  We have strict procedures in place to ensure everything we do is extremely accurate and checked and checked again.  It’s projects like this that really demonstrate how survey accuracy saves time and money.”  Read more about our surveying services.
