Here is the footage of “Site Safety Forum 2016 for Works Contracts and Property
Services Contracts”, which was held on 14 July 2016.
The speaker is Mr WONG Hung-kai, Key Account Manager of Hilti (Hong Kong)
Limited.
His presentation topic is “Application of Building Technology for Controlling Risk at
Source”.
M.C.:
Ladies and gentlemen
My friends of the industry
Hi everyone
I am from HILTI
the representative of Hilti (HK), Joe Wong
It is my honour to have the opportunity to share the following
You may be in doubt
Joe, generally speaking, your company only produces screws and power tools
and fire prevention products
Today's theme is about work at height
It seems irrelevant to us
Isn't it off track?
Yes. It really seems off track
Today, I’d like to introduce a series of
safe construction methods regarding work at height
When you hear about work at height
what is your impression?
One may think of the construction work on the external walls of building
Actually have you thought about:
A lot of interior works inside a building
involve work at height
I want to quote an example
It is about lift shaft
The height of Hong Kong buildings is increasing
The lift shafts are as tall as the buildings
The lift is installed in a narrow and deep shaft
The risk is getting high
If there are errors
it will lead to serious industrial accidents
Perhaps before we explore how we can reduce the risk at source
let's take a closer look at what important steps are involved in installing a lift
Generally, a site …
When the rooftop of building has been built
the main contractors will
hand over the lift shaft and the lift machine room to lift contractors
Lift workers will enter the shaft
And then stand on a pre-erected scaffolding
First, they will carry out setting out and hang the plumb-line
After fixing the setting out, massive holes will be drilled
Dust will be removed and anchors will be installed
Why are these done?
The purpose is to fix the guide rails on the walls and for installing counterweights
Base plate and to fix brackets
Why did I say the work was massive?
Now I would like you to make a guess
For example
a building is 40 to 50 stories high
If the two elevators are installed based on this plan
how many holes are drilled for fixing brackets?
The answer is more than 1700 holes
But the installation may not be so straightforward all the time
Often, there are difficulties
The drilling point may clash with the steel bar inside the concrete
Several trials may be needed to fix a bracket successfully
There are a lot of jobs that need to be redone
I would like to remind you here
In fact, for workers working at height
the longer they work, the greater the risk is
Are there any better methods?
Now, here is the key
You may consider the use of cast-in installation components
Cast-in Anchor Channel for installation of lift
Guide rails
and separating I-beams can be installed by this way
At the same time
the complexity of installation is also greatly reduced
For example, when a worker enters the lift shaft
he only needs to tear off the strips
and insert T-bolts
Finally, the brackets are fixed by fastening screws with the help of torque wrench
The process is very simple
With this Cast-in Channel
there are three benefits: enhanced safety, high productivity and reliability
Safety is enhanced due to shortened installation time
No need to drill holes and install screws
The installation time is reduced
that means their working time at height is greatly reduced
In addition to occupational safety and health
Since there is no need to drill holes and remove dust
it greatly reduces the chance of workers getting hearing impairment
and problem of respiratory tract infection
The second reason is the faster site progress
If coupled with the technology of scaffold-less installation
this can greatly speed up the construction pace
inspection of fire service systems, application of occupation permit, etc.
In addition, it is more reliable because:
the installation of expansion bolts
requires more manpower
and the quality may comparatively be varying
Cast-in anchors can offset these disadvantages
Does it only benefit the lift company?
In fact, we see other stakeholders
including contractors and owners can also benefit
That’s why all around the world
there are many places adopting this lift installation technology
including Switzerland, US, Middle East, India
Even our country has adopted this technology
Apart from that, cast-in components are not only used for the installation of lifts
but also for the installation of the building envelopes
and overhead electrical and mechanical fixing
Lastly, I believe in the near future
The cast-in anchor channels
will be popular in the construction industry
and widely adopted
If you have other questions
not only about cast-in components
you can share with us
Thank you
