CONS'IRUCI'1ON INIATI?R1 \IS TESTING C )SPRI?1' AcRI?s Fi o\v \v ,\NI) NATURI {PRI?SIiR\'1? 1 10E PRc )Pc )SA1, No. P17-810 • • Page -2- Floway section "D" » Bottom elevation of 6.0 feet » Design water stage of elevation 16.00 feet Weir structure S16 (top -of -weir elevation 15.30 feet) and then a 48 -inch diameter CMP discharge connection to the Indian River Farms ``eater Control District (IRFWCD) Lateral J canal (South Relief Canal) and then to the Indian River Lagoon. Miscellaneous structures and piping. The cross-sections for the various system features are currently planned with 3H:1V side slopes and varying bottom widths. Additional site improvements relative to the project include an operations building, educational trails and fencing, water main installation, paved entrance and internal driveway, parking facilities, concrete loading/compost area, etc. Finally, a Geosynthetic Clay Liner (GCL) will be installed within the settling basings, scrubbers, transfer channels, filter marshes, floways and shallow marshes. Overall, the proposed project construction schedule is 10 -months. \V understand that the services for which we arc preparing this proposal include: • Monitor proofrolling and backfilling operations and perform in-place density tests as required by the project specifications. Perform in-place density testing for building pads, driveways and parking areas, slab -on -grades, footings, pipe and structure backfill, etc. Sample and test compressive strength of concrete for building construction, weirs, footings, slab -on -grade, basins bottom slabs, etc. Sample fill and backfill soils for modified Proctor laboratory testing. Sample subgrade and base materials for modified LBR laboratory testing. Full-time GCL installation monitoring (estimated 3 months). Geotechnical and Construction Materials Testing engineering consulting throughout the project duration, as needed. As such, AACE staff will be on site to observe the work and perform tests to determine substantial compliance (relative to the services of our firm) with the project plans, specifications, and design concepts. AACE staff will not direct the Contractor nor will we have the authority to stop work. Please be aware that neither the presence of our field representatives nor the observation and testing by AACE shall imply our responsibility for defects discovered in the construction work. Further, it is understood that our firm will not be responsible for job or site safety on this project. job site safety is the sole responsibility of the Contractor. The proposed budget in this proposal was established based on a "man-hour basis", rather than a "per - test" basis, since it will be difficult to estimate the precise number of density tests for this kind of project. Another challenge to a "per -test" proposal is the periodic need for a 2"`I technician (e.g. when one technician is monitoring the GCL installation and cannot break -away for density testing of pipe trench backfill). As such, we are considering, for budgeting purposes, proposing that AACE staff be on site full-time for 6 months out of the overall 10 -month construction schedule, including the 3 months of GCL installation monitoring. That would leave another 3 months of "full-time" presence distributed over the remainder of the project, assuming that there will be days where we are not needed, days where maybe 3-4 man-hours will be needed, etc.
