The 2018-19 Budget: Department of General Services

Feb 20, 2018 - The long payback period is in part a result of the high costs of the project —$800 per gross usable square foot ($1,000 per net useable square foot). This amount is well over some other similar projects, including (1)  a recent DGS-commissioned study estimating the cost to rebuild the BOE Building and (2)  the cost of constructing private sector projects.
