Basic Services include the following: (1) save and except for those services constituting Additional Services as defined in and authorized pursuant to Article 4, below, any services that are required of Program Manager or any Subconsultant under the terms of attached Exhibits “B” or “D” or any related terms of this Agreement; (2) other professional services that would be customarily furnished by other providers of professional program management services of the type generally required by this Agreement in support of a bond program comparable in size and complexity to the District’s Bond Program for the planning, development, design and construction of facilities for schools or colleges; and (3) other services that are reasonably inferable as necessary or incidental to accomplishment the services described in preceding Clauses (1) and (2). By way of clarification to the foregoing, it is acknowledged that the scope of Basic Services is intended to address and include the management of the full range of variable circumstances and vicissitudes that can occur in managing a complex and evolving bond program and that if and to the extent the quantum of effort, time and costs required of Program Manager to perform the Basic Services increases over the course of Program Manager’s performance of this Agreement due to foreseeable or unforeseeable changes in circumstances affecting the Bond Program or the Program Manager’s management of the Bond Program, including, without limitation, acts or omissions of the District, Colleges, Contractors, Design Consultants, CPT members or Governmental Authorities, changes in the structure, requirements, or procedures of the Bond Program, or changes in the physical, fiscal or legal constraints under which Campus Projects are implemented, such quantum increases in effort, time and costs, unless they are expressly described in and pre-authorized by District under this Agreement as an Additional Service, shall constitute Basic Services.
