Abstract:
Green building construction is a momentous process of sustainability. It signifies the
environmental credibility of sustainable. Further, it addresses the energy performance,
overall cost of the construction product and conservation of natural resources.
Therefore, green building concept has foremost influence on construction industry. Yet,
it has core barriers in cost, knowledge, risk and government factors when involve the
green construction to construction industry. Hence, procurement system can involve in
reducing those barriers. Green procurement signifies both product and process of the
construction. Concerning the process base, there are different procurement systems
involved in different countries which depend on internal and external factors. There is
high involvement in design and build procurement system worldwide which include Sri
Lankan context as well. The status of applying traditional procurement system in green
construction is significantly high even though it is not considered as highest. Therefore,
it has high involvement on addressing the barriers through critical factors of traditional
procurement system. It was carried out nine expert survey with qualitative analysis in
order to identify involvement of traditional procurement system to green building
construction. Accordingly, it focused on the critical factors of traditional procurement
system specifically cost, time, complexity, client’s involvement, project characteristics
and technology. These success factors addressed the barriers which raised through high
cost, lack of knowledge, risk and other influences of green building construction. Finally,
this research subsidizes to knowledge, green procurement system provides the benefits
to increment of green building construction in Sri Lanka.
