gap analysis during one of the audit indincated that our maintenance
dept is still using the drawing board to prepare the iso and other
desing sketches. with over 3 dozens engineers, our maintenace opted
for the Bentley Microstation J - Triforma plus the L/ISO piping
package and the IRAS/B to take care of raster scannd files (eat your
heart our Intergraph user). Later on, we would rollout the Bentley
Projectwise to manage and control the workflow and documents and
then upgrade our platform to Plantspace.
We're alredy a heavy user of the Intergraph PDS and EDMS (big boys
in Engineering) but our hands-on engineers (them maintenance) have
an easy time learning the Bentley's (learning curve is just pure
fun). File compatability. No problem snce both uses the bentleys
engine so have the same file extension - irrespective wther its the
SE or J version (V8 upgrade is available for free if you're a select
user).
The wave of the future is vertical integration of the SAP, Plant
Asset Management and the Projectwise (or InteRgraPH EDMS). If this
happens, then we'll be seing a lot piping virtual engineer cutting
across borders.
