The National Science and Technology Museum was constructed using a steel frame and mat foundation. Under this foundation are more than 600 reverse circulation piles, many of which are driven all the way down to bedrock below the site. There are also rows of piles designed to keep ground water from seeping into the site.
The foundation piles with the heavy loads are subjected to many different stresses, which means it is necessary to conducts a number of load-bearing tests on-site to check the strength of the foundation and help plan the layout of the piles. These tests ensure that the foundation will be stable and meet the specifications called for in the construction contract. Eight different kinds of tests were conducted during preparation of the foundation for this project, and all were passed by wide margins. Altogether it took nearly ten months to put the 600 piles for the site into place. One of the key tools used to check the foundation during this period was ultrasonic testing.
Great design must take into account the budget allowances for a project, and must also be supported by good construction methods. The critical point for many public works projects is in economy. Many architects and engineers overlook economic considerations and will design to much higher safety standards for public-funded projects than for private projects. This is one reason that public buildings are almost always more expensive than commercial buildings. Thus the government should seek to find a balance between economy and safety in constructing public projects in the future in Taiwan.
