CR 512 RESURFACING - FROM MYRTLE ST. TO 12571 AvE. Page -3- IRC PRojEcr No. 1305 AACE Proposal No. P18-1117 Proposed Testing Frequency The following in-place density testing frequencies are typically employed by AACE for similar roadway projects: Roadways and Turnouts: Natural Ground - 1 test performed 1 foot into natural ground per 100 lineal feet, per travel direction Embankment - 1 test per 100 lineal feet, per travel direction, per 12 -inch lift Stabilized Subgrade - 1 test per 200 lineal feet, per travel direction, per 12 -inch lift Base Course - 1 test per 100 lineal feet, per travel direction, per 6 -inch lift Sidewalks - 1 test per 100 lineal feet, per 12 -inch lift of embankment or 1 foot into natural ground Curb Pad Subgrade -1 test per 100 lineal feet Drainage: Structures -1 test per 12 -inch lift of backfill, from bottom of structure to top of structure. (Fill placed on all sides of structure is probed with a manual probe rod to confirm uniform compactive effort). Piping - 1 test per 200 lineal feet (or per backfill/open cut operation) per 12 -inch lift along both sides of pipe to top -of -pipe, then every 1 foot of fill atop pipe thereafter. Concrete Testing_ A minimum of one set of four (4) cylinders will be made for every pour, and for each 50 cubic yards for larger pours. One slump test will be performed for every pour, and for each 50 cubic yards for larger pours. Proposed Scope and Budget Man -Hour Estimates: Construction will have an approximate duration of approximately 5 months, working 5 days/week. While our field technician will not be needed on-site on a full-time basis for this duration, we have included limited technician man-hours to allow for periods of "standing by" during compaction, travel portal-to-portal, soil and concrete sample pick-up, etc. Senior Field Technician; 75 hours @ $55.00/hr................................
