Canstruction is a charity event and exhibition where teams of architects, designers, engineers and contractors compete to create colossal sculptures made out of canned goods. This year’s theme is “Pop Culture.” The canned-good sculptures, embodying current trends in design, entertainment and popular lifestyle, are on display at BSA Space and in the Atlantic Wharf lobby at 280 Congress St., Boston, from Sunday, October 12, through Friday, October 31. Members of the public have the opportunity to vote online for their favorite works through the Canstruction Boston Facebook page at facebook.com/CanstructionBoston through Wednesday October 15, 1  p.m . After the sculptures are dismantled, all the canned goods, supplied by the teams and coordinated through Whole Foods Market, will be donated to the Merrimack Valley Food Bank in Lowell, Massachusetts.
