Exact Plans

This rendering shows Exact Sciences’ plans to build a 77,000-square-foot addition onto the office building it already occupies at 1 Exact Lane, the former headquarters of Spectrum Brands. The addition will include offices, a company cafeteria, fitness area and an outdoor patio.

Exact Sciences Corp. — the Madison company whose Cologuard DNA stool test screens for colorectal cancer — is building more than just a big laboratory building at its new campus just off Schroeder Road on the West Side.

Exact is submitting plans to the city to construct a 77,000-square-foot addition onto the existing four-story office building at 1 Exact Lane, formerly 601 Rayovac Drive.

The offices used to house the headquarters for consumer products company Spectrum Brands, now in Middleton. Exact bought the property in November and is updating the structure, which sat vacant for four years. Exact already has moved several hundred of its call center and administrative employees there.

Most of the new addition also will be four stories, but part of the space will be a one-story structure with a possible green roof and rooftop deck.

The addition will house offices; an employee cafeteria; fitness space; and an outdoor patio, according to a preliminary design presented to the Madison Urban Design Commission on Wednesday. A covered walkway will connect the addition to the new processing lab.

Exact has not said yet how much the addition will cost. Construction is expected to start in summer 2018 and be completed in 2020, Exact spokesman Scott Larrivee said.

Construction began in November on the new lab, whose address will be 650 Forward Drive. It will be Exact’s second facility for processing completed Cologuard tests, and at 137,000 square feet, will be big enough to handle 2 million tests a year. The current lab, on Badger Road, also is being expanded so that eventually, the company will have the capacity to put through 4.5 million tests a year.

Exact’s current headquarters are at University Research Park, where the company occupies all or part of four buildings.

Publicly traded Exact Sciences has about 1,200 employees, with more than 850 of them in the Madison area.

In documents provided to the city several months ago, the laboratory project was estimated to cost $57.3 million, but CEO Kevin Conroy later said it will cost “at least” that much.
