Proposal to provide On -Call Landscape Architectural Services — RFP No. 22-097 Task 15 - Construction Details DEA will prepare construction details for the proposed park elements such as concrete paving / finish, asphalt paving, decomposed granite paving, play surfacing, trash enclosure, shade shelter (structural calcs by manufacturer), fencing, concrete curbs, garden appurtenances, playground equipment layout, historical kiosks, and signage. Task 16 — Irriclation Plans The irrigation plans will provide the necessary information for a complete and fully automatic irrigation system for the proposed park site. The plans will indicate the point of connection(s) based upon agency requirements, backflow prevention and pressure regulation, and equipment size and type in the irrigation legend. DEA will coordinate with the local Water Department for review and approval. Effective January 2010, the State of California implemented a new water ordinance (Assembly Bill 1881) and therefore many new requirements are being requested from both the State and local agencies. We anticipate providing the following information: • Prepare water usage calculations (MAWA and ETWU) based on the new water ordinance. • Provide water efficient landscape worksheet and hydrozone table for each remote -control valve per new ordinance. • Obtain horticultural soils report (Agronomic data) based on soil samples obtained from site by DEA. Report to be provided by Soil and Plant Laboratory in Orange, CA. or equal. • Provide irrigation run time schedule per ordinance based on soil type. • Rain and wind sensors will be added per ordinance. • Add WUCOLS water use classifications for all plant material. Task 17— Planting Plans The planting plan will indicate location of proposed trees, shrubs, ground cover, turf and bioswale materials. A planting legend will denote symbols, botanical and common names, size, quantities, and remarks. Planting notes and details will also be included. DEA understands the concern for water conservation and sustainability throughout the region and therefore will select materials appropriate for the project. The plant palette established will be of drought tolerant species with a focus on materials proven successful within surrounding areas. Task 18 — Plan Submittals / Revisions DEA will submit construction plans for review by the City and will make one "round" of corrections following each review. Task 19 — Promect Specifications and Bid Schedule Technical specifications will be prepared in the desired format for the proposed park development. These technical specifications will be provided in a "boiler plate" format and DEA will modify the document accordingly. DEA requests that the City provide the boiler plate information for general conditions, instructions to bidders, and special provisions which DEA will use to provide projects specific sections. A complete bid list of quantities will be provided indicating item descriptions and unit quantities. Task 20 —Construction Cost Estimate The DEA team will provide an estimate of probable construction costs for the proposed park elements for each stage of preparation of the construction drawings (30%, 60%, and 90%). Changes will be made at each new phase of development. A detailed, line item estimate will be prepared for use as a guide in the final determination of items to be constructed under the allowed budget. Phase III Bidding Task 21 — Bid Assistance The DEA team will attend the pre -bid meeting and assist the City in responding to bidder's inquiries and request clarifications when needed.
