          | Due 
            to a high interest rate and rather limited budget for civil work construction 
            in Thailand, the firm very often has to give considerable thought 
            to provide economical structural solutions which at the same time 
            must accept the rigorous architectural and aesthetic demands imposed 
            on them. The firm has therefore gained considerable experience in 
            the use of shells, pre-stressed concrete diagrids, space frames and 
            other long span design methods together with their application to 
            these building types. |  |  |
