Built in just three weeks last year, the Oracle Innovation Lab was initially intended to show how the company’s products could be used in the construction industry, according to Burcin Kaplanoglu, the innovation officer for Oracle’s construction and engineering unit. Over the last year, more than 850 contractors, engineers, project managers — from as far as China and as close as Chicago — have visited the site. It’s success has inspired execs to expand. Starting in late December, Oracle will add technology from its utilities and communications business units to the Lab.
