Anticipated services may include, but not be limited to the following:GENERAL 1. Review construction documents prepared by other Consultants to provide cost for the material testing and theshold inspections of the project. In the event there is a discrepancy between the RFQ scope of services and the construction documents, the testing requirements and frequencies of the construction documents shall take precedence over the scope of services listed in the RFQ.2. Review, inspect, and report on specific areas of construction as required in the construction documents.3. Consultant may be required to provide technical support by the use of other Consultants when specialized areas of expertise are needed. SITE WORK SERVICESThe Consultant will be responsible for clearing and grubbing observations prior to proof rolling and filling operations, observing proof rolling operations for compliance, and conducting laboratory tests for moisture density relationship and classification. The Consultant will be required to conduct subgrade and fill soil density tests on each foot of lift of fill. Pipe backfill density test will be performed in accordance with Standard Test Frequencies. (1 test per 300 lf per 12” lift of backfill and 1 test per 12” lift at structures, unless otherwise specified)The Consultant’s asphalt base and wearing surface construction monitoring will consist of temperature tests (one for every 5 trucks), sampling for classification (one for every 500 tons), and core samples (one for every 300 lf) for thickness and density testing. The Consultant will also be required to note any irregularities in the construction techniques utilized. The School District Representative(s) must be notified immediately of any irregularities in the construction techniques utilized.Site concrete testing will include subgrade soil in-place density tests, one (1) set of 3 cylinders for every 1,000 lf of curb and sidewalk and one for every 50 cubic yards for all other site concrete. (unless otherwise specified)Retaining walls will have in-place density tests conducted within footing excavations.Foundation wall, grade beam backfill soil density tests will be conducted for every foot of fill for each 100 LF. FOUNDATIONSThe Consultant will be required to perform in-place density tests on foundation soil subgrade at a frequency of 1 test for every third column pad and 1 test for every 100 lf of footing unless otherwise specified. The Consultant will be required to inspect reinforcement and footing size per project approved drawings. CONCRETEThe Consultant’s personnel performing concrete testing must have a minimum ACI Level I certification with a minimum of two years’ experience. The Consultant will review concrete mix design submittals for compliance within the Contract documents. All concrete placement will be monitored by the Consultant to verify that air temperature at the point of placement in the structure are within acceptable limits outlined in the project specifications, inspect concrete upon arrival to verify that the proper concrete mix number, type of concrete, and concrete strength is being placed at the proper location, record any water added and note if it exceeds that allowed in the mix design. The Consultant must report any irregularities that occur with the concrete at the job site to the site superintendent and the School District Representative(s). The Consultant will record the slump, temperature and air content at the beginning of concrete placement for each batch and for each set of test cylinders made: one (1) set of four (4) test cylinders will be molded at frequencies no less than the following (unless otherwise specified):Foundation walls - one (1) set for each 150 cubic yards or fraction thereof.Grade Beams/Pile Caps - one (1) set for each 100 cubic yards or fraction thereof.Floors - one (1) set for each 5,000 square feet or floor area.Columns - one (1) set for each 100 cubic yards or fraction thereof with a minimum of two (2) sets per floor. Cylinders will be tested for compressive strength; 1 at 7 days, 2 at 28 days and 1 hold cylinder. In addition, one (1) additional cylinder per set will be molded for formed slab and pan joist floors to evaluate the concrete strength at the time of form stripping. The Consultant will be required to inspect proper welding of precast panel connection to structure for size, type, and quality. MASONRYPrism Tests: Prism tests in accordance with ASTM E-447 will be conducted for each 5,000 square foot of wall. The compressive strength prism will be assembled by the Consultant with the actual materials planned in the work. Mortar Tests: Mortar tests (ASTM C-780) will be run for each 5,000 square foot of load bearing masonry but not less than one (1) strength test for each day`s operations for each class of wall. (unless otherwise specified) Grout Prisms: Grout prisms will be molded for each 50 cubic yards of grout but not less than one (1) set for each day`s operation and tested for compressive strength, (1 at 7 days and 2 at 28 days). (unless otherwise specified) STEELConsultant’s personnel performing testing and inspection for structural steel shall be an American Welding Society (AWS) Certified Welding Inspector (CWI) for visual inspection and have the appropriate certifications for non-destructive testing. The Consultant’s specialized steel inspector will be required to perform shop and field inspections in accordance with the project specifications, as required. Shop inspections will be performed at designated fabrication shops for designated periods of time determined in consultation with the Architect, Engineer, and the Owner’s Project Representative. The Consultant will perform field inspection testing in accordance with the following:1. Obtain the planned erection procedure, and review with the erectors supervisory personnel. 2. Verify field welding procedures and obtain welder certificates. 3. Check steel as received in the field for possible shipping damage, workmanship, and piece marking. 4. Check joint preparation and fit up, backing strips, and run-out plates for welded moment connections and column splices. 5. Check preheating to assure proper temperature, uniformity, and thoroughness through the full material thickness. 6. Review welding sequence. 7. Visually inspect all field welding for size, length, and quality. 8. Perform bolt torque tests on at least 10% of the high strength bolted connections but not less than two (2) bolts selected at random in the connection and visual; inspect all bearing type bolts to verify that the bolts are snug tight. 9. Perform visual inspections on deck welds and screw placement in accordance with the project’s documents. 10. Verify proper bearing at joist supports.FLOOR FLATNESS TESTINGPerform floor flatness/levelness tests on each slab on grade pour and elevated decks (excluding pour backs).SPRAY ON FIREPROOFINGThe Consultant will provide thickness measurements, in accordance with UL design specifications, on the sprayed-on fireproofing and sample the material at each floor, for each day’s operation, and verify oven dry density.LIGHTWEIGHT CONCRETE ROOFING INSULATIONPerform plastic unit weight tests on mix for each hour of placement. Sample concrete at the frequency of one sample for each 5,000 SF of roof area placed or fraction thereof per day. Test Specimens: Mold one set of six test cylinders for each sample obtained. Perform laboratory curing, oven dry density testing, and compressive strength testing of concrete cylinder specimens. Tests will be performed at 28-days. ADDITIONAL AREAS OF TESTINGThe Consultant will be required to mold cubes in accordance with ASTM C-109 on the non-shrink grout for base plates and bearing plates. One (1) set of four (4) cubes will be made for every ten (10) base plates and bearing plates but not less than one (1) set for each day’s operation. In addition, one (1) set will be made for each day’s operation of grouting wall panels. SPECIAL INSPECTION (THRESHOLD INSPECTION) SERVICESAll threshold inspection services will be provided in accordance with Florida Statute 553. Threshold inspection services will be in strict accordance with the Project’s threshold inspection plan. Treshold buildings for the project will be Buildings 2–Auditorium, 3-Dining/Kitchen (EHPA), and 4-Gymansium/Locker Room (EHPA).Include some additional funds for threshold type inspection spot checking of buildings as requested by the Building official that are not classified as threshold buildings.
