Curtain wall supplier L. William Zahner of A. Zahner Co. produced thousands of metal sheets, each bent to a different surface contour, that skin the blob-like emp. Without the catia-centered field coordination by Hoffman Construction Co. of Washington's project engineer, Eric W. Nolander, chaos could have won out over completion of emp. Thousands have been distributed and middle and high school versions are next. These saws generate large quantities of silica dust when used to cut masonry. The dust endangers everyone on the construction site, as well as passersby.
Exposure can lead to silicosis and other lung diseases.
Local labor pacts ban the saws in Massachusetts and a number of other states. An average floor measures fl 15. Structural engineer Wilhelm H ussler has invented a significantly faster and cheaper alternative. Last year, four workers rolled 101 tons of mats in two days for a parking facility at London's Heathrow Airport. The method shaved four weeks off the schedule.
