Appendix B Cost proposal sheet.xlsx

This is a cost proposal sheet for the City of Long Beach, Department of Parks, Recreation and Marine's Lake Water Quality Management contract opportunity in California. The document outlines pricing for water quality management services across nine park lakes: Coyote Lake, Alamo Lake, North Lake, Horseshoe Lake, Nature Center North Lake, Nature Center South Lake, South Duck Pond, Heartwell Park Lake, and Scherer Park Lake. The proposal sheet is structured to capture annual costs for equipment, tools, labor, and treatment products related to current aeration system conditions and any additional or updated systems. The spreadsheet includes line items for supplemental work such as on-site labor, additional inspections, water sampling under APAP Protocol, lake evaluations measuring dissolved oxygen, electrical conductivity, pH and nutrients, aquatic weed removal, and aeration system repair and evaluation services.

The cost proposal sheet establishes unit pricing and hourly rates for various service categories, with subtotals designated for both ongoing treatment product costs and equipment/labor costs. Pricing is requested on a per-year basis for routine maintenance and management services, with separate line items for supplemental work billed at hourly rates or per-incident fees. The document also requests pricing for material supply costs, specifically for alum in 55-gallon drums. All subtotals currently display $0.00, indicating this is a blank template requiring contractors to populate their proposed costs across the identified lakes and service categories.
