Buildlogue #13 – Concrete Stuff

Thursday 3 and Friday 4 July, Construction Days 12 and 13.

Thursday was devoted to fine-tuning the steelwork and foundations, followed by the planned first visit by KCDC inspectorate. A green light to proceed with concrete was most welcome.

Friday morning, American Independence Day, is clear and bright, brilliant sunshine, but brawny grown locals were trying to warm their hands and mumbling about how cold it was. At 10:00am in the morning!

Builder John and his men added some final extra support to their shuttering, and also drove in a number of fence pegs (to be able to beacon off the concreted area from the dog paws!) 

First to arrive was Hurricane Concrete Pumping service, with a 30 metre extension hose. He discusses the operation with Builder John and they come to the conclusion that a better solution would be to bring the vehicles into the narrow driveway, and then to pump the concrete over the roof of the house!

v3
(Above): No sooner had he positioned his pump truck in front of the garage door, when two Terry Concrete trucks arrive in quick succession. It was quite a trick operation getting these trucks into the driveway and located, to be able to discharge the load into the pump hopper.

v4
(Above): The Hurricane pump-truck lined up, with the driver using a remotely-controlled panel, so that his superstructure doesn’t accidentally damage the roofing sheets.

 V5
(Above): The two vehicles married up to be able to pump the concrete through the pipe, up and over the hose and along the ground behind the garage and kitchen to the destination site.

V9
(Above): A close-up of the pump-truck’s hopper being fed from the chute from the pre-mix truck.

V6
(Above): The thick rubber pressure pipe with metal unions runs the full 30 metres from the pump-truck, up and over the roof, down at the back of the garage and along the ground past the kitchen.

V7
(Above): The pump guy dispensing the concrete slurry a-la-Kiwi-style.  Back-breaking work, like an All Black rugby prop!

V8
(Above): The cement guy scrapes the bottom of the barrel and chute, before driving back to his depot in Te Horo for his next load.

V9a
(Above): With the first load done, they get on with the serious business of getting everything perfectly level and smooth.

V9b
(Above): Finally, the cast is complete and everything smoothed down, for the next stage of the process later today.

V9c
(Above) Builder John erects a barrier fence around the development to dog-proof the freshly-laid cement floor.

v9d
(Above) Later in the afternoon, the cement floor is polished smooth. A vinyl plank floor will be laid on top of the cured concrete surface in due course.

Buildlogue #7–Dig Done

Tuesday 24th June: Construction Day 5 of the project. One again, we wake up to icy frost on the lawns on Monday23rd (Day 4), but again an absolutely clear summer, with some light showers in the forecast for tomorrow Tuesday (Day 5), probably clearing in the afternoon.

Last on Buildlogue… You will recall that we left the building site almost filled and compacted to target levels and floor slab boundaries by Gary The Elder on Friday afternoon. 

Monday, Gary & Gary get out the pick and shovels and manually dig out the outer foundations for the slab around the southern side in front of the main house dining/ living room to a depth of 300mm. The going is tough in the rocky clay soil, but these two guys appear to approach their task with the same dedication as they do when operating their excavating machines.

After consulting with Builder John about the precise positioning of polystyrene foam along the outer 3 metre perimeter band, they go about accurately surfacing the hardfill to the level specified by the architect. This implies that the central part of the extension hardfill is higher than the 3-metre zone by the thickness of the insulation. Then comes a final 20mm bedding layer of builder’s sand, ready for the preparation of the fitting of the steel reinforcement and the of casting the foundation slab by the builder, starting, weather permitting, on Wednesday.

Gary and Gary neaten up their work and start clearing all traces that earthmovers had been to Chartwell north wing. The work includes the tip-zone on the front lawn, which has suffered somewhat under the very wet saturated “terra infirma”.

Tuesday, and the final spit and polish work by way of site housekeeping is done, the earthmoving equipment and tools finally laden before we say farewell to the guys. The dogs will miss the excitement, to which they have almost become accustomed, whenever one of their trucks arrives or leaves.

Thanks to Bryce and his men for the polite ways and professional approach to their job! Cheers, guys.
