Kleinfelder Statement of Qualifications for On -Call Material Testing and Special Inspection Services for City of Santa Ana, RFP No. 20-111 * Site grading * Foundation excavations * Backfill placement * Subgrade preparation * Pile driving * Drilled pier construction * Rock anchor placement * Precast concrete inspection * Welding inspection * Concrete paving * Reinforcement placement * Batch plant inspection * Concrete placement * Asphalt paving * Soil improvement * Load tests * Steel construction * Painting * Masonry construction * High strength bolting * Expansion bolting * Drainage systems * Field instrumentation * Underpinning * Source inspection * Fabrication shop inspection Listed below are the standard materials testing and inspection services which we expect to perform on this contract and have provided for similar on -call contracts: Soil and Agaregate Sampling and Testing. Our certified technicians will sample soil and aggregate using ASTM Standard Practice D75 for the appropriate laboratory testing, which may include sieve analysis, sand equivalent, cleanness value, R-value, maximum density, specific gravity, durability, soundness, and expansion potential. Bituminous Mixture Sampling and Testing. Our certified technicians will sample asphalt concrete mixtures in the field or at the batch plant using ASTM D979 for laboratory testing which may include maximum theoretical unit weight, asphalt extraction, stability, moisture and rutting susceptibility, and gradation analysis. Soil and Base Compaction Testing. Our certified technicians observe placement of soils and aggregate base material and conduct field testing using a nuclear gauge device or sand cone to evaluate the in -place density and moisture of the material and to calculate relative compaction. Results of soil and aggregate base compaction and density testing taken at the job site will be submitted to the City's designated representatives within 24 hours. Micro -surfacing and Slurry Seal. Our certified technicians observe the placement of slurry seal, scrub seal and micro -surfacing materials for resurfacing of the existing roadways. They check for oversize material, monitor mix temperature, proper mixing, and blending of the mix. Our inspectors can also collect samples of slurry seal for wet -track abrasion testing. Asphalt Compaction Testing. Our certified technicians observe placement and compaction of HMA material using nuclear density gauges in accordance with California Test Method 375. Results of asphalt compaction and density testing taken at the job site will be submitted to the City's designated representatives within 24 hours. Asphalt Batch Plant Inspection. Our certified technicians routinely provide batch plant inspection during paving operations to observe and document material quantities, mixing temperatures, binder type and temperatures. They collect samples of asphalt and aggregates and conduct moisture tests and grain size analysis. They also ticket the load for identification by the field inspector. Concrete Batch Plant Inspection. Our certified technicians perform observation and documentation of procedures used in concrete batching. At the batch plant, the inspector monitors and records weights of ingredients for concrete, including admixtures. They also monitor mixing of concrete, slump, addition of water, and adherence to the approved mix design. They will ticket the load for identification by the field inspector. Inspection of Reinforcing Steel at the Fabrication Plant. Our deputy inspectors identify and sample reinforcing steel at the fabrication plant and tag the steel for recognition upon arrival at the project site. We also collect samples of reinforcing steel which are transported to our facility for laboratory testing (bend and tensile) as required by the project plans and specifications. /QE/NFELOER MNn_ insz4 srl Kleinfelder 116 �'
