Wisconsin DOT’s “MDSS” RFP ExperienceMarch, 2005 Tom Martinelli Winter Operations Engineer
Contract Background • Weather forecast services contract expired after last winter • Needed to explore new ways of doing business • Wanted more frequent forecasts and more emphasis on computer modeling
WisDOT’s Weather Forecast Services RFP • Used NCAR MDSS template as a guide • Required 3-hourly updates vs hourly in guide • Required vendor to run all forecast and decision support software • Text and graphical outputs • Eliminated items deemed not necessary or too difficult to implement • Weather parameters like drifting snow • Decision support was optional item
Mandatory RFP Items(similar to old contract) • Required the following for one point in each of our 72 counties • All forecast parameters out to 24 hours • Surface air temperature, dew point, RH, wind • Precipitation amount and intensity • 24-72 hour statewide outlook • Winter storm warning service (pager/cell phone) • Toll-free access to forecaster
Mandatory RFP Items (new items) • Forecast confidence • Conditional probability of precipitation type • Road and bridge condition products • Pavement, bridge frost potential
Decision Support Limitations • Treatment recommendations was an optional proposal item • WisDOT concerned about cost (limited budget) • Little GPS/AVL used in Wisconsin means treatment feedback is limited • Could use initial treatment recommendation, but then would be “business as usual” without treatment feedback loop • Three proposals, but only one gave cost, and it was very high
