And if so which engineer? Where in MF04 would the spec for these bollards be located?

In MF04 they would be in 347113 Vehicle Barriers. (347113.16 is Vehicle Crash Barriers). These products come in various designs--continuous wedge-shaped, individual spaced bollards--and to resist varying loads. It is up to the building owner to tell the architect the level of protection required, for example to resist an XX thousand pound truck traveling at YY miles per hour. William C.

They are very specialized and have lots of different options (for stopping power on what they will stop as well as lots of different options for security interface. No engineer on either of our projects would touch them, even security said they would not do them. In both cases, a manufacturer was brought in and we worked with them. In both cases though their products were very good, their documentation was not, think of writing a performance/descriptive style spec in stream of consciousness. So, it took going back and forth a couple times with them to get their information in a viable/biddable form. In both cases for use here, the owner had their own security requirements internally and when the package was completed, it was sent to them first to review. Both projects it went through several reviews where we then had to go back to the manufacturer to provide additional information that they had left out (they had been given the original requirements from the owner, they just 'missed' certain requirements. So you might want to build that kind of thing in. Where located in MasterFormat: Division 34, Transportation Section 347513 Operable Roadway Equipment That is a broadscope designation. But there is an actual sub number reserved specifically for this... Section 347513.13, Active Vehicle Barriers Dave puts his in 347113, but technically those are supposed to be static (meaning non-operable). But there is nothing wrong with putting them there or in 347513 2 manufacturers we worked with were...

"Division 34 is not our responsibility" Yet another reason for not using MF1995 -grin! William William C. Pegues, FCSI, CCS, SCIP Affiliate WDG Architecture, Washington, DC | Dallas, TX Jerome J.
