Though its project is already a year or so behind schedule, officials at Bon Secours Virginia Health System say they are still on track to build a comprehensive new cancer center at Harbour View.

“It’s a very complex and comprehensive project,” said Joe Oddis, chief executive officer of Bon Secours Maryview Health Center, a complex that includes the Health Center at Harbour View.

Leeanne Sciolto, then Bon Secours Hampton Roads’ administrative director for oncology services, said at the beginning of June 2012 that construction on the Harbour View facility would start within about 12 months.

Sciolto made that prediction after the 81,500-suare foot, three-story, $10.8 million Bon Secours Cancer Institute at Harbour View had received a certificate of public need from the state health commissioner.

On Wednesday, Oddis said a developer partner and final design would be announced within 60 to 90 days.

Groundbreaking is expected before the end of 2014, he said, with a projected build time of 12 to 15 months.

“We are doing the appropriate planning and really trying to achieve the level of excellence that we want in the project overall,” Oddis said.

A lot has been added “programmatically” to the plans during the past couple of years, he said.

The additions relate to specialist services aimed at cancer prevention and early detection, he said. Those services would be located at the center alongside a radiotherapy center with a CT scanner and a linear accelerator for radiation therapy.

“There will be a number of multi-disciplinary clinics,” Oddis said. “The programmatic plan, I would say, is almost virtually identical to what was originally planned, just enhanced with some more specialists and others that we have brought on board.”

The primary care and other cancer specialists would “help to deal with prevention and early identification,” he said.

“It will be a state-of-the-art cancer institute that … has a full range of specialists and primary care services for the region we serve,” which includes Suffolk, Isle of Wight County, Portsmouth and western Chesapeake.

The 13-acre development site, located between Bon Secours’ current 172,000-square foot Harbour View campus and the new Meridian apartment complex, would increase the campus size to 23 acres, said Barbara Lynch, Bon Secours Hampton Roads’ vice president and ambulatory services.

Patients today are seeking ambulatory health care facilities over hospitals, Lynch said.

“That’s just a national trend across the country,” she said.
