healing, and most importantly aligns a final design the City's ultimate objective In the preliminary phase our team evaluated the hydraulics and scour analysis to provide some initial recommendations It was determined that the use of check dams, practical slope armoring, and slope cut backs of 2 1 would address the existing erosive conditions The design also reviewed the use of culverts to provide pedestrian crossings and to help protect oak tree's in proximity of the channel We detailed non -grouted rip -rap, gabions, and geotextiles that we considered minimally acceptable to reduce flow velocities The City requested that the design provide the aesthetic appeal of a recreational park and that the team consider larger riprap slabs with subtle entry into the channel, as seen in pictures that were provided They have further expressed that protection of slope be considered in both east and west banks to equalize the feel of the channel To deliver construction documents that builds from the preliminary design with an intent to refine the h/s study, details, and proposes alternatives to address aesthetics we are requesting support from in house leads in landscape and structural design We are also recommending that the project engage the geotechnical engineer to evaluate the soil conditions and provide geotechnical recommendations within the project boundary The following scope for preparation of construction documents for the Oakmont Park Channel Rehabilitation is based solely upon the scope of services, compensation, schedule, terms and conditions as specifically detailed herein ADVANCEDESIGN" Mr John Harris Oakmont Park Channel Rehabilitation — Construction Documents March 31,2022 HUITFZOLLARS SCOPE OF SERVICES. 1 0 Engineering Services As described above the scope of services in all task below is limited to analysis of a portion of the channel at Oakmont Park More specifically limits that begin at an upstream end with the outlets at Sutherland Drive and extend approximately 800 linear feet downstream, as shown in our preliminary design drawings 1 1 Channel Design Provide drawings (plan and profile) for 100°/0 design of the Oakmont Park channel The design will continue to identify locations along the channel for application of specific erosive reduction measures such as check dams, slope armoring, culverts, gabions, and grading to stabilize the channel's erosion Availability of materials with local quarries will be verified A rough grading plan will be generated to establish the anticipated limits of work, as well as construction entrance(s) to the bottom of the channel More specifically HZ will provide an evaluation of the design revisions related to the landscape design This includes changes to slope and application of rip -rap through the channel We will develop details and cross sections to deliver on the city's goal for aesthetics The plans will provide sufficient information for an engineer's estimate of probable cost Deliverable 70% Progress Design and Engineer's Estimate Only 90% PS&Es 100% (Final Design) PS&Es 1 2 Hydraulic and Scour Evaluation• Update the hydraulic model for the proposed design to reflect the 100% design Our current preliminary analysis will be used to provide recommendations for 100% design for the Oakmont Park channel and then modified to match the deliverable at 70% and 90% design The final hydraulic study will include a hydraulic model for the extents of the project, sizing of the bank repairs, check dams, pedestrian culvert crossing, and rip -rap aprons 1 3 Landscape Support. Huitt-Zollars' landscape architect will coordinate with the city and research local stone quarries to determine the type of boulders or boulder slabs available in the area The landscape design team will then work closely with the civil engineer to develop the detail and cross sections that deliver on the city's goal(s) for aesthetics Separate landscaping and irrigation plans are excluded and if required a separate scope and fee will be provided to the CLIENT for review and approval 1.4 Structural Support The design will require structural support to evaluate the stability of large boulders or boulder slabs and other erosive measure Our structural team will work closely with the design team to provide supporting calculations Page 12 Mr John Harris Oakmont Park Channel Rehabilitation — Construction Documents March 31,2022 HUITLZOLLARS 1 5 Geotechnical Engineering To access the stability of soils, determine structural parameters, and provide recommendations to protect from further erosion damage Our geotechnical consultant will conduct a field investigation and prepare a report which includes • Project Setup Geotech will determine and field mark boring locations Notify Underground Service Alert (USA) Engage a drill rig to sample the subsurface soils • Field Investigation Plan for three (3) borings along the channel Approximate depth of 25 feet Drilled with a track -mounted rig equipped (hollow -stem augers) Backfill with loose soil cuttings City shall monitor and backfill settlement as necessary, if construction is delayed • Laboratory Testing In -place moisture and density Expansion index Laboratory maximum density Direct Shear • Engineering Analysis and Report Project description Summary of conditions Description of the field procedures Discussion of materials encountered Discussion of properties Exploratory logs Approximate depth of groundwater, if encountered Discussion of lab test results Location of active faults within 62 miles Seismic coefficient based on 2016 CBC Discussion of Liquefaction Slope stability evaluation Slope construction recommendations Soils bearing capacity Lateral earth pressures 1.6 Engineer's Estimate of Probable Cost. Huitt-Zollars will prepare an engineer's estimate of probable cost at 70%, 90% and 100% design The opinion of probable construction cost will use industry -standard unit costs, ENR construction costs, and available City cost database 1.7 Specifications. Huitt-Zollars will prepare one set of project specifications Specifications will be derived from city's boilerplate document and/or APWA standard specifications Specification will be submitted at 90% and 100% design Page 13 Mr John Harris Oakmont Park Channel Rehabilitation — Construction Documents March 31,2022 HUITLZOLLARS 2 0 Meeting and Project Management• 2 1 Meetings and Project Management This item includes time for meetings, phone calls, conference calls, coordination, and other project managementtasks 2.2 ECORP's Meetings and Coordination This item includes time for Ecorp's participation in meetings, phone calls, conference calls, coordination, and other project tasks II COMPENSATION All services provided for this project will be billed monthly on a time and materials (T&M) based on 2022 hourly rates (See Attachment A) 1.0 Engineering Services 1.1 Channel Design $56,500 1 2 Hydraulic and Scour Evaluation $32,000 1 3 Landscape Support $30,000 1 4 Structural Support $19,500 1 5 Geotechnical Engineering $20,500 1 6 Engineer's Estimate $ 9,000 1.7 Specifications $10,500 Sub Total for Engineering Services $178,000 2 0 Meetings and Project Management 2 1 Meetings & Project Management 2 2 ECORP's Meeting and Coordination Sub Total for Meetings and Project Management 3 0 Reimbursable Expenses $16,000 $ 5,000 $21,000 3 1 Reimbursable expenses are estimated at $500 which include deliveries, mileage, and production of bidding and construction documents Expenses shall be compensated as agreed upon in the original contract The total estimated budget for all above items. $199,500 Page I 4 Mr John Harris Oakmont Park Channel Rehabilitation — Construction Documents March 31,2022 HUITT-ZOLLARS III DELIVERABLE.
