You are a Contracting Officer’s Representative, and the Contracting Officer has given you a draft of what may be a unilateral change order. The first “ballpark” estimate judges costs may increase by $5-10M. Delivery will likely be set back by 3-6 months. Far more stringent inspection requirements will be involved. Experts within your agency disagree wildly on the impacts. You know the contractor has remedies if they judge the change to be outside the scope of work. How will you advise the CO to minimize delays to achieving contract outcomes beyond impact of the change itself?
