Jan 2021 - Joining the Pieces Together

After an energising break over Christmas we're right back into action. This month we have begun working on the stitch joins that join the precast concrete panels together, putting in and tying the reinforcing steel, then boxing up the framework before filling with concrete.

The final big section of raft slab is being poured today (28th Jan!) with the concrete team starting on site at 5:40am this morning! 

We've also achieved the first of the upper floor slab pours, a cell/room on level 1.  The reason for pouring the upper levels in cells is the precast panel temporary propping system. The panels are supported by large steel props bolted into and between the panel and raft slab until the rest of the structure (stitch joins, floor slabs) are in place, enabling the props to be removed. There are roughly 15 cells to pour per level, and planning the sequencing of these pours around installing and removing the temporary propping, as well as coordinating timing for production and delivery of other structural elements has proved an interesting challenge for the Aoraki site management team.

The order of precast panels and slab pours may seem a little illogical but is designed around propping and forming slabs in the most efficient manner.

Dec 2020 - Up, Up, Up!

There's been another step change on site over the last few weeks - we're building up!

The formation of the raft slabs has been quite an undertaking, involving careful coordination to ensure the large concrete pours go smoothly. This included starting the concrete pour early on a Saturday morning to ensure we could get consistent flow of concrete delivery trucks to site without hitting traffic congestion. Two out of three of the ground floor raft slabs have now been poured. When finished, the ground floor will contain 1,100 cubic meters of concrete!!!

While preparing to pour the final section of raft slab we are also standing our large precast panels on site. These large upright structures are once again dramatically transforming the look of the site as we build vertically 3 floors at a time.  


Formation of the Level 1 and Level 2 suspended floor slabs are scheduled to commence early next year so that will be the next major change to look out for!

of concrete in this particular pour.

After pouring, concrete is first vibrated and then floated to smooth the surface. Curing compound is applied and it is left to set.

Precast panels installed and temporarily propped ahead of the suspended floor slabs and in-situ stitch joints being formed. Each panel is 3-storeys high, a further 3-storey high panel will be stacked on top of these panels at a later date, taking this structure up to roof level. 

Precast panel being lifted from the truck and rotated using both the tower crane and mobile crane, before the tower crane guides this panel into its final position.

Preparation for installation of precast panels on the newly formed raft slab is underway, including setup of the mobile crane that will assist our tower crane with rotating the precast panels once lifted from the delivery trucks.

Nov 2020 - New Crane on the Block!

There's a buzz of excitement on the site now that our crane is up and fully operational! It signals another new phase of construction, and we can now concentrate on getting ready to pour the ground floor raft slab.  

The ground floor raft slab will be poured in three sections. The first is scheduled to be poured by the end of the month. In preparation for this we have been focusing on completing the inground services, with our reinforcing steel fixers following close behind tying the mammoth volume of steel in the raft slab. The second section is due to be poured in December, and the third and final section is due to be poured in the New Year.

While preparing for our first section raft slab to be formed we are also working on forming the lift pit on site, as well as completing services infrastructure work out on both King Street and Adelaide road.

Oct 2020 - Preparing for our Crane

One of our first major milestones has now been met - the piling is complete! Brian Perry Civil did a great job and have now de-camped, leaving the site looking quite different to before they arrived.


Out on Adelaide Road,  G.P. Friel have been busy installing the underground services to service the new apartment building, including new storm water manholes on Adelaide Road - quite a challenge on such a high volume traffic area.


The next major will be getting our crane up, and to that end we have been busily preparing the crane base. The crane base makes clever use of the building's foundations and will therefore remain in place once the crane has been removed. Our crane will have the capacity to lift up to 24 tonnes so that it be able to handle the large precast panels on our project, and will stand approximately 10 storeys high in order for our 3 storey precast panels to be lifted over the top of the building as we progress through construction.

Sept 2020 - Piles, piles, and more piles!

The focus over the last few weeks has been piling, and with ~160 piles to get in this is no small job. There is quite a high variability in how easy/hard each pile is to drill, and so far they have ranged from taking about 8 minutes to 2 hours to drill a single pile. In brief, for each pile a 13m deep hole is drilled, filled with concrete, and then reinforcing set into it. Check out the reinforcing being driven into the concrete (click here!) - its quite mesmerising!

Despite some  obstructions being encountered, Brian Perry Civil are putting in a great effort and progressing well - we're on track to have piling completed in early October. 

Towards the end of last week, GP Friel were working on Adelaide Road excavating for and installing storm water manholes and we started preparing the ground for the crane base/slab, which will soon have reinforcement put in and tied between 6 piles.

Aug 2020 - We are GO!

It's been a busy two months since we signed on to deliver the Monark Apartment development in June; the building that was on site has come down and been removed, our team have moved onto site, extensive groundworks have been completed to prepare the ground, services are in the process of being re-routed, and piling has commenced (3 completed, ~157 to go!) 

Show More

The team have arrived! Site office is in place and the the site has been cleared ready for the next stage.

It's getting busier on site now as Brian Perry Civil get stuck into work on the piling.

For each pile, a hole must be drilled, filled with concrete, and reinforcing driven down to a depth of 13m.

If you have property, development or construction needs, or know someone who does, we would be delighted to hear from you!
