Dunedin Botanical Gardens Plant Nursery and Propagation Facility

Client: Dunedin City Council

Architect: Mccoy and Wixon

Main Contractor: Cook Brothers Construction

Completion Date: 2014

The Project

The new propagation and nursery facilities on Lovelock Avenue are the biggest investment in the Dunedin Botanic Garden’s history. Soon after the turn of the century the Dunedin City Council identified the old plant nursery facility was both ageing beyond repair and inefficient. The environmental management systems became less energy efficient and inadequate to produce the variety of plants needed by the Garden.

The new facility features a new potting and propagation area, office spaces & teaching spaces and a glasshouse which hosts 8 fully automated habitats.

This complex project involved intricate detailing and flashing work and we are very proud of the end result.

The Roofing Project

The existing building had a zero degree concrete slab roofwith a leaking bitumous membrane. Weight concerns and significant plant and ventilation requirements meant the options were limited as to which system to install.

A tapered scheme Viking Warmroof at 2 degrees pitch was selected. The insulation is designed to the specifically to the requirements of the roof: falls, hips, valleys, gutters etc created entirely from Kingspan Polyiso Insulation. This lightweight option achieves an R-rating of 8 across the Science Block Roof and at its highest point is 460mm thick.

Enviroclad membrane is installed as the waterproofing layer over the top of the insulation. Enviroclad was selected due to the systems ability to successfully and robustly terminate over 200 penetrations from 50mm in diameter to over a metre square.

The Roofing Project

The 1400m2 project included a plywood substrate. The 2 degree pitch roof is visible from many surrounding buildings so the finish had to be perfect.

Due to Viking Enviroclads 3.6 m wide and 30.4 metre long rolls the project was able to be executed with minimal laps.

This project is a Viking Full System Warranty project only able to be undertaken by licensed applicators who have trained to a level 3 training certification.

The Result

The result is an extremely attractive, perfectly watertight roof installed to the highest standards and delivered on time while enabling the day to day operational and educational activities of the Polytechnic to continue with the minimum of disruption.
