SACKVILLE, N.B. – Sackville town hall will get a rooftop garden after all.
Members of town council awarded a $130,000 contract this month to Avondale Construction Ltd. for the construction of a garden/green roof at the new municipal building, despite the project being shelved earlier this year when the only bid submitted (at nearly $190,000) came in higher than what was budgeted ($150,000-$160,000).
Andrew Amos, the lead engineering consultant who oversaw the design and construction phase of the municipal building, said when the green roof was initially put on hold back in May, he decided to try and outsource the project and bring down the costs so the town could move forward on their rooftop garden.
“I felt it was an important element of the town hall project so I wanted to see if I could resurrect it,” he said.
The green roof concept will include a combination of hard surface areas, such as patio stone walkways and a deck for events, as well as vegetated planting areas.
"The completion of the green roof will represent the final expenditure by the town on this project,” said Amos. “It was an element that had significant environmental value to the project and we wanted to ensure we received the best value for money when it came to this expenditure."
Amos explained there are a number of benefits to having a portion of roof covered in vegetation - it retains water thereby reducing run off (especially important considering the Lorne Street floodplain); it significantly reduces the heat flux through the roof and therefore reduces energy for cooling and heating; and lastly, it protects the waterproofing membrane of the roof which results in a significant extension of the roof's lifespan.
"The building is meeting its energy targets and this addition of a layer of insulating media will only further assist in lowering energy costs, thereby saving the town even more money as time goes on.”
The contractor will begin work on the rooftop garden next week and is anticipated to complete the project by mid-October.
