CADLiew Yong Seong

B.Eng (Hons.), M.Eng, MIES, MSSS

28 Dec 2011


Mr. Liew Yong Seong graduated with a Bachelor and Master Degree in Structural Engineering. He is currently the technical director of Advance Contech (S) Pte. Ltd. He supports and trains clients from local and international consulting and construction firms in using advanced engineering software solutions to streamline design and construction processes of high-rise, reinforced concrete and steel structures with or without post-tensioning and precast components. Over the years of support and training, he has assisted many engineers in solving and fixing modelling and design problems. He is also currently the Regional Representative of prestigious engineering software developers, Forum8 (Japan), RISA Technology (USA) and SE CAD Software -- the world first integrated Analysis, Design and Detailing System for Precast Building Structures.

Introduction to SE CAD

a brief history of time

28 Dec 2011


Introduction to SE CAD : History

streamline construction processes to meet the challenges ahead with the use of advanced technologies

28 Dec 2011


In-situ RC construction

Dependent of foreign labors Slow and weather dependent Wastage of materials Difficult quality control Environmental issue Non-systematic and messy

>> Solution : use of prefabrication (precast) technology!

28 Dec 2011


Use of conventional software and structural system hinder the use of prefab and precast technology

Does Not promote standardization Error prone Difficult to check and archive data

The road-blocks

28 Dec 2011


Conventional RC design and detailing : The designers and checkers night mare! Tonnes of drawings to be drawn, checked

and archived

Industrial Precast Building◦ Factories, Warehouses, Plants etc.◦ Mainly Function-oriented◦ Long/Ultra-long spans◦ Corbels◦ Pre-stressed T-beam, double-T etc. (simply supported,

semi-rigid connection)◦ Proprietary connector

Residential Precast Building◦ HDB flats, quarters, schools, offices◦ Function-and-aesthetic-oriented◦ Short/Mid spans

Type of Precast Building Systems

Low-rise (bungalow) to high-rise (50 or more stories)

Beam of short to medium span length (4 ~ 8 meters)

Floor : Beam-Slab system Lateral resistance to wind provided by

shear walls + columns & beam-column frame stiffness

Full or hybrid system of in-situ and precast
