02 1 Scope of Services and Schedule
<br />Preparation of a written report presenting the results of our field exploration, laboratory testing, and
<br />engineering analyses, as well as our conclusions and recommendations relative to the geotechnical
<br />aspects of project design and construction.
<br />Upon substantial completion of the project plans and specifications, Ninyo & Moore can perform a
<br />geotechnical and geologic plan review to evaluate whether the conclusions and recommendations
<br />presented in our report were correctly interpreted and incorporated into the project plans and
<br />specifications. These services can be performed if requested and authorized.
<br />Soils and Materials Testing & Special Inspection Services
<br />Our soils and materials testing and inspection services may include the following, depending on the
<br />requirements of the specific task order assignment:
<br />• Project coordination and client liaison, including scheduling of personnel to provide observation and
<br />materials testing services and meeting attendance.
<br />• Review of readily available background materials pertaining to the site, including geotechnical reports,
<br />project plans, and specifications.
<br />• Attendance at pre -construction and field meetings as requested by the client.
<br />• On -site soil and materials testing and inspection during construction on an as -requested basis. Our
<br />inspection services will be performed in accordance with the applicable building codes requirements
<br />project's plans and specifications. Our soils and materials testing and inspection services can include
<br />the following:
<br />• Field observation and inspection during foundation construction, including observation of footing
<br />excavations, pier drilling, pile driving, as appropriate.
<br />• Field observation, documentation and testing during the earthwork operations. Our services will
<br />include observation and field density testing of compacted fill, including embankment fill, structure
<br />and wall backfill, utility trench backfill, subgrade, aggregate subbase, aggregate base, materials.
<br />• Field sampling and in -place density testing will be performed during asphalt pavement construction.
<br />Asphalt production plant inspection and sampling will be performed to evaluate conformance with
<br />project specifications. Laboratory testing of raw aggregate and completed mix samples will include
<br />sieve analysis, sand equivalent, percent asphalt, film stripping, CKE, swell, and maximum density
<br />per the Construction Manual and project specifications.
<br />• Field sampling and testing of concrete structures and paving during construction. Our field testing
<br />services will include sampling of concrete, and evaluating the temperature, penetration, air content,
<br />and unit weight. Concrete cylinders will be cast during concrete placement for structures and will be
<br />transported to our laboratory for compressive strength testing. Concrete beams will be cast during
<br />concrete paving and transported to our laboratory for flexural strength testing. Concrete batch plant
<br />inspection and sampling will be performed to obtain raw aggregate samples for acceptance testing
<br />and to evaluate the batch plant operation for conformance with project specifications. Laboratory
<br />testing of aggregate samples will include sieve analysis, sand equivalent, and cleanness value per
<br />the Construction Manual, Standard Specifications, and project Special Provisions. Further,
<br />specialized tests, such as L.A. rattler, durability index, specific gravity, etc., will be performed upon
<br />request by the Resident Engineer.
<br />• Field inspection of the construction materials, both during fabrication/ erection/construction and after
<br />construction completion (finish project inspections) performed by inspectors registered with the
<br />County of Orange and other agencies (ICC, AWS-CWI). Inspections may include:
<br />• Reinforced concrete, including foundations, cast -in -place concrete structures, and miscellaneous
<br />concrete construction.
<br />• Structural masonry, including retaining walls, sound walls, building and site walls.
<br />o Onsite and fabrication shop welding and bolting of structural steel.
<br />Non -Destructive Testing (ultrasonic, magnetic particle and dye penetrant)
<br />Roofing, painting and coating
