Seamless Connection For BB Tower
Developer: YTL Corporation Bhd
Main Contractor: Syarikat Pembenaan Yeoh Tiong Lay Sdn Bhd
Product Supplied: Invisible Connections TSS41 along with Halfen Cast-In Channel, Moment® Coupler and Plakabox
Project Description
The Requirement: To connect precast concrete staircases and walls without denting the appearance of architecture.
The Solution
The TSS units were developed as a connection detail between precast landings or stairs and walls in stairways, and all that is required in the wall is a recess. The inner tube is retracted into the unit during erection, to be pulled out into the recess when the precast element is in the correct position. A safety stop will prevent the inner tube from excess protrusion. A rubber pad at the support in the wall is available in order to reduce the impact sound transfer from the stairs to the walls. It provides hidden connection, quick erection, and no site work is necessary with bolts, welding or mortar.
Other than TSS41, Halfen Cast-In Channels with ETA-16/0453 approval & CE Marking approvals were supplied for façade fixings, while Moment® Coupler and Plakabox were also used in the development for connection reinforcement.
The Result
TSS41 being cast in precast staircase landing

Advantages of Invisible Connections
After installation, there is an invisible connection, with no visible supports.
2) Reduce impact sound from the stairways
The Invisible Connection System has several ways for sound insulation. From the more ordinary to the remarkable sound reduction.
3) Safe and simple installation on site
With a crane the elements are safe and quickly located in the shafts. The correct method is to support the elements from beneath, level the element and pull out the inner tubes into the recesses. For the permanent connection, the recesses are then filled with mortar.
4) No welding or bolting on site
By using our systems you avoid welding and bolting on site. Only filling up the recesses with mortar is needed. Uniform performance.
5) Simple design of walls
Easy to plan the recesses in both precast walls and in moulds on site, due to standard location and sizes. Less use of crane time on site. The installation time is shorter, compared to similar systems. Saving crane hours and money.
6) Standard box for wall recesses
The Invisible Connection System has also standard boxes for planning the recesses. These are corresponding to the size of the units. For steel moulds, they are magnetic.
7) Technical approved systems
The Invisible Connection System is ETA approved system.
No visible corbels and reducing the waiting time for the crane

Exhibiting at HSR Asia 2017 Summit
Partnering with our sister company from Germany, HALFEN, Halfen Moment Group participated in the HSR Asia 2017, a 2 days intensive international summit event in Kuala Lumpur, addressing the current challenges that countries are facing to push ahead with their high speed rail development plans. HALFEN Fastening Systems for tunnels were presented during the summit.
The safe operation of tunnels greatly depends on the durable fixation of all required technical and operational equipment. The paramount superior objective to ensure safety of the installed equipment over the duration of the entire scheduled service life is not realizable without paying utmost attention to the correct design, selection and installation of suitable state-of-the-art fixing systems. For a safe and cost-efficient tunnel operation, the fixing technology used for the installation of the tunnel equipment is as important as the tunnel construction itself!
While the initial costs of fixing technology are rather low compared to the overall tunnel cost, fixing failure could turn out at the end of the day highly costly and tragically for more than just the innocent victims! HALFEN cast-in channels have proven to be extremely safe, reliable and cost-effective. They have become preferred alternatives to traditional methods such as post installed anchors due to the manifold advantages they offer.
Typically HALFEN cast-in channels have been used for various applications, such as:
1) Electrification
2) Cross passage connecting doors
3) Platform screen doors
4) Fixing of lighting and signaling devices
5) Fixing of ventilation
6) Suspended ceilings

Greater KL, the right place for a global leader
Based in Greater KL, the construction accessories business, Halfen Moment Group, is part of CRH plc, a global leader in building material, with a number of strategic footholds in the ASEAN market.
CRH plc (CRH) is the second largest building materials company globally, the largest in North America, and the largest heavyside player in Europe. In Greater KL, CRH’s presence includes the headquarters of the Halfen Moment Group, these headquarters functions as part of CRH’s broader construction accessories business in Asia,” says Andi Lapon, managing director of Halfen Moment.
CRH offers a diverse portfolio of products and services across the entire spectrum of construction solutions. Its products are categorised into three key segments: heavyside materials, lightside products, and building materials distribution. The focus of CRH’s local operations in Malaysia is in construction accessories, which falls under the lightside product segment.
Headquartered in Ireland, CRH is a constituent of the FTSE 100 index. The Fortune 500 company is also listed on the Irish Stock Exchange and its American Depositary Shares are listed on the New York Stock Exchange. It currently employs over 87,000 people across 31 countries around the world. At the end of last year, CRH posted a 15% sales growth from 2015 to €27.1 billion on which pre-tax profit soared by 69% to €1.7 billion.
In Malaysia, the Halfen Moment Group, was acquired by CRH in 2012. The Halfen Moment Group specialises in efficiency-increasing construction accessories for building-site structures and industrialised building systems (IBS).
IBS is a construction technique whereby components are manufactured in a controlled environment, either on site or off site, and then placed and assembled into construction works. It is widely regarded as the way forward in the construction industry. It can reduce both construction time and labour costs.
“Quality is a major concern during the construction process and if there is no established system of quality certification, every initiative to increase the quality of products used on site has to be supported. The Construction Industry Development Board (CIDB) has a crucial role here and in my experience they take this role very seriously. By having a body that focuses on (build) quality and more importantly enforces their policies, the standards and quality of the products are set to improve. With stringent quality control, potential dangers can be diminished as we control and reduce the quantity of low quality (building) supplies that make their way to (Malaysian) building sites,” says Lapon.
“I am convinced that in the long run and given the right strategy, CIDB can further elevate (the construction industry in) Malaysia. In my opinion though, there is opportunity for Malaysia and the CIDB to look at, easier to implement solutions on site that reduce the need of labour tremendously, and can increase build quality. Halfen Moment Group, for instance carry products that reduce labour by over 60% on site while increasing the quality of construction. However, these products now have to compete with cheaper low quality workarounds, and are therefore hard to introduce,” says Lapon.
Improving The Building Quality
Quality control does not end with raw material checks, it should extend to the validation of the entire product design. “Let me use an analogy. If I buy a Bentley car, the quality of the steel used in the car is crucial, but it doesn`t tell the entire story about the quality of the car. We at CRH always emphasize on high quality products which are well designed and engineered; from end-to-end,” says Lapon.
The Malaysian Advantage
“The Malaysian Government has done many things to reduce the cost of doing business. The use of English as the main business language also makes it easy for Western companies to operate here. Furthermore, agencies like InvestKL are ready to support multinationals that set foot in Malaysia. They are an excellent facilitator for companies that need to find a way through a complex web of protocols and organisations.” adds Lapon.
Buidling Talent, A Strategic Asset
“I have worked in Antwerp, Toulouse, Barcelona before working in Kuala Lumpur. When we acquire businesses, we always look internally before filling vacancies with external candidates. There are global employment opportunities for employees that master their jobs,” says Lapon.
“I am blessed with a great team.We have a hardworking and well-educated workforce that is open to change, and are eager to become better. The company competes internationally and this would not be possible without the right people in place,” says Lapon.
He says that being part of a global group of companies is also beneficial as local talent is often exposed to their foreign counterparts. “I see more people from Asia Pacific visiting and collaborating with their peers in Europe today. I believe that such international exposure can also be very rewarding on both professional and personal levels.
Through a gap analysis and appraisal interviews, we understand the training needs of our people. This allows us to have a structured training plan.. Training never stops in CRH. It’s an on-going process,” says Lapon.
“I believe experience is the key for any talent, hence we often look for talents that who will grow alongside with the company. Whilst we are mindful there will be inherent cultural differences, individuals with high adaptability and embrace change will find CRH an exciting place to work in,” says Lapon.
CRH through Halfen Moment has a partnership with University Malaya aimed at developing young engineers in the country. Here, Halfen Moment works on new innovations and offers training and apprenticeship opportunities to young talent. “We work on joint-innovations for developments such as housing projects. We are considering introducing business cases with practical construction challenges to encourage students to come up with possible solutions. This will help them to bridge the gap between theory and reality. Another idea is the establishment of an innovative body where students or alumni can design, innovate and patent new construction products,” says Lapon.

KAHRAMAA – Water Security Mega Reservoirs Project
Developer: Qatar General Electricity and Water Corporation
Main Contractor: Consolidated Contracting Group (CCC) & Teyseer Contracting Co. JV
Product Supplied: Epoxy Moment® JoinTec Coupler
Project Description
The first phase of the project will provide the 7 days of storage for the expected water demand at horizon 2026, with 5 mega reservoir sites. The second phase will provide the 7 days of water storage for expected demand in 2036 by adding additional reservoirs within the 5 mega reservoirs sites.
The Requirement: In order to prevent corrosion at this salt water structure, this project requires epoxy coated couplers to connect with the epoxy coated steel bars.
The Solution
A total of 2.5million Epoxy JoinTec Coupler were commissioned (300,000 couplers to be delivered each month), hence the production line and operators were expanded to meet the production capacity and for better quality control. These Epoxy JoinTec Couplers had went through a few rounds of quality measures before delivered, below were the main areas focused:
1) Threads to be free from epoxy coating
2) Visibility of the marking on the couplers after coating
3) Dimension and threading check
4) Tensile test for each batch of couplers
Standards operating procedures and strict quality control protocols were the keys to maintain the quality of the couplers and also to keep to the promised delivery timeline.
On top of that, 26 threading machines were also supplied and mobilized on site to produce the threading of 5 million threads. It was a challenge for the threading machines to work under a high temperature between 40-50 degrees in Qatar, therefore these machines were all maintained regularly to avoid any unexpected breakdown during production.
The Result
Picture above showing Epoxy Moment® JoinTec Coupler and rebar threading performed at site.

Rebar Coupler for Structural Integrity
Traditional Method of Connecting Rebars
For more than a century, construction practices in the building of concrete structures have focused on the use of steel reinforcement to transfer tension forces. Lap splicing became the traditional method of connecting the steel reinforcing bars, largely due to a misunderstanding that lap splicing is a “no-cost” splicing. Lap splicing requires the overlapping of two parallel bars. The overlap load transfer mechanism relies on the concrete around it to transfer the load.
However, lap splicing is not always the proper means of connecting reinforcing bars for the following reasons:
• Use of lapped joints is time consuming in terms of design and installation
• Lead to serious congestion within the concrete due to the increased lapped rebar volume
• Lapped joints are very dependent upon the quality of the concrete for load transfer
• Poor compaction of the concrete will compromise the performance of the joint and might result in ‘honeycombs’
Stains, corrosion and breakage of starter bars left for future extension
Reinforcement Coupler System: The Technology for Present and Future
Today, the use of mechanical splices or widely known as rebar coupler is superior in its load transfer to lapped splicing as it creates a direct mechanical connection between the 2 bars which is similar in its behavior to a continuous reinforcing bar.
In general the use of coupler for rebar will:
• Improve structural integrity
• Improve design options
• Achieve an ideal balance of steel and concrete by eliminating unnecessary rebar
• Reduce the congestion and weight of the structure.
• Lessens the amount of embodied CO2
• Reduce the rebar cost as lapping uses more steel than couplers
So there are only advantages…
Rebar coupler avoids bend and rebend of reinforcement bar and improve site safety
Other than the benefits listed, trends toward stronger buildings, increased geography impacted by seismic zone mapping and increasing needs for safer buildings will also affect the potential value of a building. Hence, with many different types of reinforcing coupler system available in the market, designers can easily incorporate them into future plans.
A wide range of rebar couplers for different applications is available at Leviat, rebar coupler supplier. As the strength of the coupler connection depends on qualitative threading of the rebars, do only rely on a serious partner who offers consistent and controlled quality threads.
