Management of Municipal Library Construction Projects

I am seeking clarification on the legal provisions regarding the oversight and management of construction projects by a municipal library. Our Law Department has previously indicated that the library board is not authorized to handle construction projects directly, asserting that it is the responsibility of the town. However, assuming full compliance with municipal laws, would it be permissible for the library to manage its construction projects if we hire a qualified project manager and maintain close coordination with the accounting department for payments?

Could you please advise on the legal framework that governs these responsibilities and whether there is any flexibility for the library board to take on such a role?

Thank you for your guidance on this matter.
