City staff activities required to complete tasks are noted where applicable. Scope assumptions applicable to the overall Project are described below. Project-level Assumptions • All deliverables will be delivered in electronic formats, with no printed copies. Bid documents will be digitally signed and sealed. City, Contractors, and City’s CM firms shall be responsible for hard copy reproduction of bidding and construction documents. BC will be responsible for hard copy reproductions for their own purposes. • Engineer, where used herein, shall mean BC and its subconsultants. • Unless otherwise specified, meetings and workshops will be held virtually. • Construction period services begin with bid opening and conclude with final acceptance of the work by the City. • Services during contractor’s general warranty/guarantee period are not included. • City PM will provide timely, consolidated staff review comments on draft work products. City review periods will be identified in project schedules. • Owner’s Representatives include BC, its subconsultants, City staff, and City’s CM firm that represent Owner’s interests in the Construction Contract that are employed or retained by the Owner. • Mileage for in person meetings and site visits are budgeted assuming the visits are to the Port Gardner site. • Meeting agendas and notes will be prepared by BC unless otherwise stated. • Labor and expense effort is inflated at 5% per annum for work taking place after 2026. • Work extent and sequence: The scope of work and budget allocation to each phase and task is based on a number of assumptions regarding how the work is envisioned to proceed. Given the nature of services during construction, the actual level of effort required for each phase/task may require reallocation of funds from one phase/task to another. • The scope and budget do not include effort for preparing submittals for the City’s insurer or responding to review comments that may result from the City’s insurer review.
