Engineers, Steel Piles and Carport

[JAS21]

I started this topic as I thought someone may be interested in the work of the two engineers and also the steel piles.

 

It all started off at the ‘Architect18’ exhibition where we went to choose some roofing material for my proposed shed. Eventually we settled on a product called HoloRoof after talking to both the Factory owner who was there from Indonesia and the importer.  

 

Whilst there we saw that the company also built car port extensions so arranged for them to visit and discuss. We had wanted something to keep the cars dry for quite some while but quotes we had were silly money and we didn’t like any of the proposed designs.

 

The guy, who turned out to be an electrical engineer, his wife, and the erector, a civil engineer visited and we spent probably two hours discussing options. We had already looked at some of his extensions and similar one from other companies.

 

We agreed a design; the thing that concerned us most was the support pillars having seen some that just didn’t look right. I have to admit here that initially we asked for four 4*4’s (3.2mm) in a square with some small steels between. Later realised that was over the top so we had another discussion and changed the 4*4’s to 3*3’s. After the steels arrived we decided that an L-shape was preferable to a square. Fortunately we will use the spare 3*3’s for my shed which they will build in a couple of weeks.

 

Initially we were going to have the supports on the drive but decided to have them further out and to use two meter steel piles which are certificated to support two tones in firm ground.    

 

During construction we learned that the Prosper Tech guy was involved in heavy electrical work and also had electricians who wired houses etc, the Civil engineer also built houses and house extensions.

Before and preparation  

 

Setting the levels and alignment ... here was when we found that the house wasn't built exactly straight ...

 

The steel piles arrive ... no it is not photo shopped

Sinking the first steel pile ... drill first and the screw in the pile. They found the ground exceptionally hard so for the later piles they pre drilled with a thinner pile.

 

 

 

Mrs J discussing with the Civil guy

Some rebar was welded into the holes on the pile top ... a plate with six holes was then placed over the rebar, aligned and welded.

Shows the plates

Support pillars in construction ... covered for the night in case it rains

Pile bases covered in a sand and grout mixture ... not points for levelling

Steel work in progress

More discussion

More steel work

Roof going on

 

The UPVC is quite flexible but very strong, shiny side up ...same as when laying turf ... green side up

Quality top coat

Gutter is stainless steel with white down pipes .. quite a neat job I thought

Finished

 

Not sure if a little extra decoration is needed below the front 6*2 ... to make the front look deeper ... plenty of time to decide

I have to admit that when JAS sent me that photo I thought he was having a wind-up, giant woodscrews indeed.

 

Turns out he wasn't and these things go up to ones big enough to support a house and larger.

 

The piles people are Kemrex https://www.kemrex.com/ some installation videos on Youtube.

I was exceptionally pleased and impressed with everything during construction ... unlike many companies the staff from   PROSPER TECH CO.,LTD. worked well and didn't cut corners and tidied up each evening. Each morning the Civil engineer brought them to side, sorted any problems/changes/queries from us!! gave them instructions on what and how to do. He then disappeared for a while to look at another of his jobs ... returned later.

 

After a while I didn't do more than a quick look at what they were doing ... didn't need to

One question.

 

The piles are hollow, are they filled with grout or similar so they don't fill with water?

Maybe these big wood screws are sealed off and don't let in water . The helical piles I observed being installed on China railway's were galvanized tubes with wide screw plate at the bottom and filled with some kind of cement after installation.

 

There's a company in Chonburi doing similar canopy work using a small Kubota with auger attachment to install poured concrete piles.

I noticed those foundations at both the Architect Expo and a recent Solar Expo. Looks like the OP found a great application for this home building product.

I didn't see them there ... guess wasn't looking ... might have got a even better deal direct....?

Mrs JAS saw you ogling Bob the Builder and moved you on rapidly to look at toilet valves or something.
