Home Browse Search

Proposal to provide Landscape Architectural Design for Standard -McFadden Park — RFP No. 21-055 The following items are not included in this scope of services: ■ Record of Survey Map Preparation, Review and Recordation with the County ■ Corner Records Map Preparation, Review and Recordation with the County ■ Extensive Boundary survey ■ Title Reports ■ Legal descriptions/plats ■ Utility Mapping Deliverables: Topographic Survey as noted above. Task 4 — Geotechnical Investigation Project Set-up Under the direction of the project manager, a staff professional will set-up the project to provide the services outlined under our scope of work. The project set-up will include the following. ■ Coordinate with City representative to schedule the field investigation. ■ Stake the boring locations prior to drilling. ■ Notify Underground Service Alert (USA) to clear the boring locations of conflict with underground utilities. ■ Arrange for a drill rig. Field exploration will consist of drilling a total of seven borings and conducting water infiltration tests. Borings will be drilled to depths of 5 feet (2), 15 feet (3) and 50 feet (1) below existing ground surface (bgs) or to refusal, whichever is more shallow. The purpose of the borings will be to obtain subsurface information, and obtain undisturbed and bulk samples of the various soil types for laboratory testing. The borings will be backfilled with soils cuttings and tamped. Fitness Equipment at Memory Lane Park Public Workshop Meeting for Bryce Hanes Park Percolation Test: We understand surface runoff will be captured on -site with overflows discharged within the site via a drainage device. Two percolation tests, one- to five -feet and the other to ten -feet deep, will be conducted to estimate the water infiltration rate. Laboratory Testing: The laboratory testing program will depend upon the type of soils encountered during our field exploration and the quality of samples obtained. Laboratory tests will include, but may not be limited to R-value, expansion index, and soils corrosivity. Report Preparation: Data obtained from the exploratory borings and the laboratory testing program will be evaluated. A report will be prepared which will include the following items. ■ Logs of the exploratory borings summarizing the subsurface conditions encountered, and a plan indicating the locations of the explorations. ■ Depth to groundwater (if encountered) and its impact on the proposed development. ■ Location of active faults relative to the site and its impact. ■ Design seismic coefficient based on the 2016 CBC. ■ Water infiltration rate. ■ Grading recommendations, including removal of unsuitable soils. ■ Shrinkage and subsidence coefficients. ■ Subgrade preparation for slab, foundation and walkway. ■ Structural backfill recommendation ■ Soils bearing pressure for shallow foundation design. 10 1 June 3, 2021 1 David Evans and Associates, Inc.
