INTRODUCTION Amendment Eight took effect on August 31, 2019, to provide engineering services and support for additional remedial investigation (RI; Phase 1) and develop the workplan for additional pilot testing of remedial alternatives (Phase 2 Workplan). Scope and budget have been added and the schedule extended through four prior changes: • Change No. 1 added to the scope, added $387,970 to the budget, extended the schedule through May 28, 2021, and temporarily reduced Parametrix's labor multiplier. • Change No. 2 extended services, added $75,000 to the budget, and extended the schedule through July 30, 2021. • Change No. 3 extended services, added $85,000 to the budget, and extended the schedule through December 31, 2021, including two minor schedule extensions. • Change No. 4 extended services, added $80,000 to the budget, and extended the schedule through April 30, 2022, including one minor schedule extension. Change No. 5 is needed to cover costs during schedule extensions because Phase 1 Report and draft Phase 2 Workplan comment resolution has been extended. Change No. 5 excludes the following services: • Dispute resolution • Feasibility study completion, including additional pilot testing Dispute resolution services, if needed, will be provided under a separate agreement. Feasibility study completion and additional pilot testing will be added to Amendment Eight as a future task.
