Bids for the Hawley School HVAC project in Newtown have come in above budget.  Residents signed off on $8 million for the work, but the lowest bid was $250,000 above that price.  During the recent Public Building and Site Commission meeting, First Selectman Dan Rosenthal said it's a pretty straight forward project so there's not a lot of room to find savings.  He suggested installing one new unit to cool 6 classrooms not currently air conditioned, rather than replacing the 6 air conditioning units in the west wing of the school, which were installed in 1997.  Rosenthal noted that the units could be replaced in a later project. Officials hope to perform the work during the summer to avoid student disruptions.
