MASSENA â Although thereâs been a 30% increase in the price of tin, that hasnât impacted the Massena Central School Districtâs $49.6 million capital project. James Francesconi, senior project manager for C&S Companies, the districtâs construction management firm, told board of education members that Northern Mechanicals was seeing an increase in a couple of other projects. The firm was awarded the mechanical construction contract for the Massena Central project. âThey havenât reported that yet on this project, obviously. I think itâs because they got ahead of the game. Theyâre starting sooner rather than later,â Mr. Francesconi said.
