STANDARD AGREEMENT FOR PROFESSIONAL SERVICES Page 2 of 3 Between City of South Bend and ARCADIS U.S., Inc. Proiect Number: 03029034.0000 AMENDMENT No. 3 Schedule A-1 Scope of Amended Services and Related Matters ENGINEERING SERVICES BY ARCADIS General Administration: Arcadis provided general administration services related to clarifications and interpretations (5 additional RFIs), change orders (44 additional change requests resulting in 6 approved change orders), and other matters to fully close the project. Arcadis provided services through the Contractor's extended schedule as further described below. This also includes reconciling Arcadis' subconsultants for their time and materials spent, which was less than anticipated for CMID and more than anticipated for Donohue (assumed low range of their anticipated budget at a key design stage), with an overall net increase which cut into Arcadis' budget for services provided through the entire project, especially as it related to services associated with changes and the claim as part of the project. Meetings and Site Visits: Arcadis attended meetings and observed the progress of Contractor's executed work during same visits, which extended beyond the anticipated Substantial Completion date of March 8, 2018 as noted in the previous Amendment No. 2. The Contractor's work was substantially complete in November 2018 with additional close-out items occurring through December 2018. This was approximately 10 months of additional schedule. Record Drawings: Arcadis and its subconsultants provided additional services to incorporate the numerous substitutions that were accepted during construction for cost savings into the record drawings.
