OSPA strives for speedy negotiations but the timeliness of contract negotiation is also dependent on the amount of time sponsors require to review and seek approvals for changes. A timeframe of several weeks is likely if contract issues are complex. See OSPA Award Information here.
OIPTT completes about two-thirds of the negotiations within 30 days after receipt of the GoldSheet and the notice of funding. See Negotiation Timeline and Factors here (pdf).
