NEHEMIAH TOWOONG BRIDGETECH
Nehemiah Towoong Bridgetech Sdn Bhd is a member of the Nehemiah group of companies. It shares the DNA of the group, holding the same vision, mission and core values as the larger group. Like our parent company (Nehemiah Group), we are committed to conducting business with integrity and providing the highest quality products and services in the markets we enter.
The Nehemiah group of companies taps into international technology by forming a joint venture with Towoong E & C (Engineering and Construction). Towoong E & C has been recently awarded a letter of commendation from the Korean Government giving them the title of “Excellent Overseas Construction Company”. Using the latest in bridge construction technology from South Korea, we are able to build bridges with span as long as 60m. This super long span girder is called BH Girder™.
in comparison to other types of beams, BH Girder is:
Optimized cross section that achieves long spans and low depth. Prestressing efficiency is optimized by using the intermediate tendon and straight tendon arrangement.
Substructure cost, slab cost and earthwork cost reduced by use of BH girder.
Increased span length makes for a more streamlined shape, improving the overall aesthetic which is also improved by requiring less piers.
Due to increased span length, BH Girder requires less spans overall reducing the number of installations. This coupled with rigid and stable spans makes for simpler hoisting and an overall easier installation.
Shorter Construction Period
Construction period is reduced by 45-60% because of the omission of some piers due to the increase in maximum span length.
With the use of a reduced number of piers, there is a reduced impact on the natural landscape.

Malaysia Book of Records
The BH Girder is one of the upgraded PSC girders that utilized the Bulb-T shape integrated with Half Slab and can be applied over a long distance of 60m at once. Compared to other types of PSC Girder bridges, it is an entirely new type of bridge that has achieved the 3 goals of “Low Cost”, “Fast Construction” and “High Safety”.
Half Slab Integrated slab girder for improving constructibility
Improvement of Aesthetic View Stream lined shape
Bulb-T Shape The structural efficiency can be maximized
Maximization of prestressing efficiency
Connection of Slab Special lap splice of rebar
Straight Tendon The friction loss can be minimized
