This phase of the project will consist of bidding services, construction contract administration and observation, and construction staking. This scope of work also includes several miscellaneous design tasks that were either new tasks specifically directed by the City of Bozeman or tasks that had unique design challenges that were unexpected during the development of the original scope of work. A detailed scope of services for these tasks is outlined below. Phase 1 - Project Initiation This phase of the project includes preparation of the scope of work and amendment.

Below is a list of the specific challenges that had additional design costs that could not be absorbed into the original scope of work and budget. · Storm Drain Design o Regional Storm Pond Analysis – requested by the City of Bozeman in April 2020 o Challenges with drainage design associated with underground constraints (gas and water main) to provide stormwater quantity and quality treatment. DocuSign Envelope ID: 91D85752-252E-42AB-B45B-0D2EB35FCEAE o Revisions to the storm drain design after the Preliminary Plan submittal associated with revisions to the approaches and path/sidewalk alignment, which resulted in multiple drainage design iterations and multiple rounds of stormwater calculations. o Addition of Phillips 66 runoff into City storm drain system · Relocation of the water main at Manley Road and completion of associated DEQ design reports and checklist, as well as additional design time associated with replacing and relocating all of the existing fire hydrants on the corridor. · Challenges associated with significant difference in grade between Griffin Drive and the adjacent properties, as well as general approach design modifications requested by adjacent property owners. o Unexpected modifications to the profile to meet drive approach standards and avoid impacts to the Gallatin Village Trailer Court and Whalen Tire properties in particular. o Profile modifications resulted in the need for additional flowable fill over the gas main. o Additional survey to determine the proposed approach tie in locations to the existing ground surface. o Revisions to storm drain design associated with profile changes. o Multiple approach design iterations due to changes requested by Phillips 66, ExxonMobil, Whalen Tire, Eagle Tire, HRDC, Mountain Supply and others. The following items are not expected to be needed for this project and are therefore specifically excluded from this scope of work: · Material testing (By City Term Contract) · SWPPP permitting and operation (By Contractor) Fees and Billing Arrangements: Phase Fee 1.
