"We've worked closely alongside them to ensure they move into premises suitable for them and where we can help we've negotiated rent subsidies," he said.
RDT Pacific associate director Sheryl Kirner said the work would be done in three stages and take four months.
The first stage will involve stripping of internal linings, doors, mirrors, cabinets, electrical and plumbing fittings, plant and equipment. Due to the age of the building a number of items contain asbestos and as part of stage two this will be removed by a licensed asbestos removal company.
The final stage involves a crane and a high-reach excavator with a "nibbler" which will break down the building in sections from the top down. The excavator will have a mist sprayer at the end of its arm to wet the structure and minimise dust.
The building will be broken down piece by piece with rubble cleared away regularly to keep the site tidy. Contractors will monitor the building's integrity regularly to ensure the safety of workers, the public, and those in adjacent buildings.
Meanwhile an access road between the library and the Community House where people drop off their library books into a book drop bin while still in their cars has been shut down for safety reasons.
A book drop bin remains at the front of the library in Haupapa Street.
