Many of the designers who prepareestimates were interested in runningtheir own bid analysis.

Installing BAMS/DSS on all their

machines did not seem practical at thetime.

Nearly everyone has Microsoft Excel

installed and I loved the challenge.



3/38

Links to wTrnsports Oracle Database

to pull in real time bid results.

A stand alone version pulls data from a

static database file that has to be

updated from time to time.

Does not have all the functionality of

BAMS/DSS.

User friendly and readily available.

Many of the designers who prepareestimates were interested in quick and

easy access to actual bid history and

other minor statistical item bid

information.

Nearly everyone has Microsoft Excel

installed and I loved the challenge.
