Mr. Chairman, age has affected some of the equipment in the building and certainly it makes it appropriate to change that equipment anyway. It is at the end of its useful life. That really does not speak to the capacity issue.
The capacity issue is more related again to the standards which have changed since the building was built. It was built to the building code standards and the standards of the time. In those days, the perception of what was required in order to meet or maintain a healthy work environment is quite different than today. It is now recognized that a substantial amount more ventilation area is required in order to maintain a healthy working environment. The codes have changed and it is now necessary to meet the new codes.
To some extent that is a structural problem in the building. We actually have to enlarge the access to the building in order to pull in enough air and circulate enough air to all of the floors.
There is another issue in that building. The building was initially, if I recall correctly, built as five floors. The sixth floor was an add-on and was not envisioned as part of the initial ventilation system. The ventilation system has been piece-mealed as well. All of those factors mean that we need to invest heavily into the building's ventilation and air conditioning systems.
