The architectural elevations of those high-rise buildings are almost glass, and curtain walls are typically used. The main features of curtain walls are noise insulation, anti-heat, water proofing, stain resistance, high wind pressure tolerance, easy maintenance and energy saving.
However, what worries developers and contractors the most, is the quality of curtain walls. While there are a large numbers of suppliers – both joint ventures and foreign ones – there is no official standards for curtain walls since Vietnam has just recently exposed to this new technology. As a result, developers and contractors of each individual project apply their own standard, which makes it very difficult to confirm and identify the quality of the products.
Unfortunately, no laboratory can carry out this testing as there lack of equipment, technology and commonly accepted standards. Owners have to take samples to overseas such as from Korea, Hong Kong or Singapore for testing, which is very costly and time consuming.
As no current wall test is being conducted in Vietnam, there is a need for the establishment of a quality testing company.
Some considerations include:
(i) whether such a company is feasible and profitable,
(ii) how to process this kind of testing company technically and economically,
(iii) Whether the demand is high, and what are architecture demands and trends?
Mr. Nguyen Duy Duc Thu made a case study which objectives were to: (1) develop technical and economic feasibility study of Curtain wall testing company; (2) identify demand (volume and market trend) and the needed supply of curtain wall testing company in Vietnam; (3) identify technical requirements of curtain wall testing in Vietnam which includes testing specifications, labs and equipment engineering knowledge competency and quality control; and (4) develop business plans and marketing plans.

Abstract
Nowadays there are many high rise building had been built in over Vietnam, especially in Hanoi. The building was using for many find of propose such as office building, commercial building, hotels… and others. But they had a common that is using the curtain wall for elevation.
But there’s very difficult in order to testing and qualify this kind of material.
The thesis is focus on feasibility study of curtain wall testing company, under the perspective of technical requirement, business plan and marketing plan.
