Collaborative Design Approach definition
Collaborative Design Approach. DJ&A will prioritize early scoping and coordination with the City of Missoula to ensure alignment on project goals, design criteria, and key deliverables, culminating in a 30% design submittal package. Work items within this subtask include: • Initial stakeholder engagement to establish project goals, design criteria, and concept design. • Preparation of preliminary demolition plans. • Development of preliminary geometric layouts, including roadway improvements (Ryman Street Plan & Profiles), trails, sidewalks, intersection improvements, greenways, crosswalks, and connections to Front Street (Figure X). • Creation of preliminary landscaping and planting plans for boulevards and greenways. • Development of preliminary traffic control and signage plans. • Preparation of Stage 1 and Stage 2 submittal documents per City of Missoula standards. • Identification of potential impacts (e.g. private sidewalk connections, parking, R/W, signage, sprinkler systems, etc.) on adjacent properties. • Preparation of quantity take-offs and preliminary Engineer’s Opinion of Probable Construction Costs (OPCC). • Submission of design development documents and coordination with City Public Works and Mobility and Parks and Recreation staff through virtual meetings. • Permanent traffic control at the Ryman Street (with the proposed greenway improvements) connection to Front Street will be non-signalized (stop controlled, urban mini-roundabout, including traffic calming design elements, or similar non- mechanical/electrical intersection controls); • DJ&A will coordinate with utility companies early on to ensure there are no utility conflicts within the proposed construction limits and to avoid potential impacts to existing utilities; • All landscaping will be designed in accordance with the Missoula Parks and Recreation Design Manual 2018 Edition. Technical specifications governing the landscape plan will be provided directly on the plan sheets with reference to the aforementioned Design Manual and no separate specifications document package will be produced. Landscape details will utilize City of Missoula Parks and Recreation Standard details where applicable; o It is assumed that boulevard typology will be developed based on the Downtown Missoula Master Plan. o Irrigation design for boulevards is not included, as this level of detail will be added during 60% design as applicable. • No utility services will be provided as a part of this design package; • Trail, sidewalk, roadway, ...
