We have extensive experience
in utilizing various finite element programs such as NASTRAN,
Algor, Strudl, Ansys, etc. in performing sophisticated dynamic
analysis. Frequency response functions, time history
analysis, modal analyses, dynamic soil-structure interaction
are a few of types of dynamic analyses performed in our projects.
We pride ourselves in having gained valuable experience by
field testing of a significant number of structures, tools,
etc. using shaker and hammer systems.
In our design of Advanced Facilities, we use our extensive
analytical and practical experience
in determining the need for such design elements as structural
isolation breaks between different building systems, foundation
design types, and horizontal stiffening. Our experience
also allows us to make smart design decisions; we have often
been praised for simplifying structural systems -- realizing
significant cost savings -- without compromising the dynamic
performance of facilities.

We pride ourselves for having designed
and tested hundreds of semiconductor tool pedestals and other
secondary structures. We have gained valuable experience
in field testing of
pedestals (using two-channel impact hammer
We are keenly aware of fabrication and installation limitations
of various constructions at connections (welding or bolting)
and anchorage points and use our experience to ensure that
system-limiting local compliances do not thwart a theoretically
sound design. With our knowledge of tool sensitivities
and understanding of fab structural dynamics, we design these
pedestals to minimize interaction between the building structure
and the pedestal.
