Crews will start drilling in front of RIH starting today, part of the plans for the new clinical building.
Interior Health Authority said geotechnical drilling will be done Friday and Saturday to help architects and engineers to plan building design.
IHA awarded a contract in September to architecture firm DIALOGUE for what it calls indicative design and functional programming. That drawing will show how the clinical service building will be designed as well as budget scenarios.
The first phase of Royal Inland Hospital redevelopment is slated to cost $80 million.
IHA said trees lining Columbia Street will not be affected by drilling.
