Low headroom drilling for heritage building

By | Case Studies, Uncategorized

Access Piering were engaged by Icon Construction to provide foundation piles for new hotel development that was inside a heritage building in Chippendale.

The design was for a new structure built from the inside, retaining and utilising the heritage facade. The first challenge was to drill foundation piles working around the existing structure. The second challenge was to have enough firepower on site to meet the very ambitious program.

The building was demolished back to the ‘bare bones’ structure. This proved a difficult challenge for drilling as we had to carefully work our way in and around existing structure that was keeping the building in place.

Fortunately we were able to respond to the challenge of the site conditions and the program. By utilising our 2 low headroom machines on site at the same time, we almost halved the program time. We were also able to work in all available areas. Working with heritage buildings and foundations, no everything goes according to plan, so sometimes we drilled – hit something that had to be removed – and we were able to move onto another area and keep drilling.

They laughed when I told them the cost of the Foundations

The foundations cost more than the house

We recently met with a new Client, who was referred to us from one of the bigger Builders in town. He was looking to build a lower ground floor to a small workers cottage in Rozelle. At first pass, the drawings looked simple enough, CFA piers as shoring walls.

But when we looked at the Geotechnical Report, there was sound rock only 1 m from the surface. To create the lower floor was going to take some serious rock drilling. So I gave them the price and they laughed, and said,

“You can’t be serious, this costs more than the house!!”

After the laughter died down, we dug a test hole on site, and Access Piering was able to offer a Design and Construct package for the foundations. We got our Engineer involved, deleted one wall entirely, changed one wall to underpinning, and the other to a soldier pile detail.

We saved the Client thousands of real dollars, making the project viable.

In these tough times, we have some very real advice to make sure you don’t get ripped off next time you buy Foundations
