Costing Small Cleanroom
Dr. Cheong Eng Gan and Liu
Yang, National University of Singapore
The quick development of high technology and life sciences industries
nowadays sees the need for more and better cleanrooms in modern
laboratories expanding dramatically.
Cleanrooms, as mechanically intensive facilities that consume
large amount of energy to maintain its defined environment have
high capital and operating costs. Furthermore owners want the cleanrooms
to be constructed for less money, in less time, with higher performance
standards, and lower running costs.
Most cleanroom designs and construction are customized for a wide
ranging scale of operations.
To date, there is no complete study on cost that is based on the
whole lifetime of cleanrooms. There is no standard cost system
available. This made the exercise of quantifying, varying and projecting
costs of cleanroom design and construction difficult. To enable
accurate costing, it is necessary to establish a considerate cost
framework based on the critical parameters of the facility.
This paper defines critical elements of cleanroom design that
would impact significantly on the costs of its construction. It
also presents the relationships in a cost model. The cost model
is applied to small cleanrooms that are increasingly demanded by
entrepreneurs and small and medium enterprises. Such small, standard
and modular cleanrooms are suitable for individual inventors, small
high technology production and school laboratories.
Cheong Eng Gan has a B.Sc (Building)
from the University of Singapore, a MBM from the Asian Institute
of Management and a Phd from the National University of Singapore.
He has worked in the construction industry as project consultant
and tertiary institution as faculty member in Singapore and Asia.
He has 25 years of research and industrial experience in large
and specialized development projects.
Cheong Eng Gan is currently employed by the Department of Building,
School of Design and Environment, National University of Singapore
as Associate Professor. He leads the research group investigating
on life cycle and costing of specialized buildings and elements.
This group concentrates on new building technology and its applications.
Current work in collaboration with professional and commercial
organizations includes applications to high technology buildings
and their performances.
Liu Yang has a Bachelor of Civil Engineering
and a Bachelor of International Finance from the Shanghai Jiao
Tong University and she is pursing a postgraduate research degree
in M.Sc.(Building) in National University of Singapore (NUS) now.
She has 5 years of work experience in project budgeting and management
in Shanghai Hua Hong NEC electronics Co., Ltd and its predecessor
Shanghai Hua Hong Microelectronics Co., Ltd. in cleanroom construction.
Miss Yang has been a research student in Dept. of Building, NUS
for one year. Now she has completed her course study and is researching
into the topic on life cycle costing for cleanrooms as her graduate
thesis. From last October, she has been participating in an on-going
research project: Life cycle costing of High Technology Building:
Case of Life Science Research Building, which is sponsored by NUS,
icfox (Singapore) and Davis Langdon & Seah.
