The Project Name for this Task Order 10163 is as follows: CITY OF MERIDIAN SPECIAL INSPECTION AND TESTING SERVICES MERIDIAN WWTP MAINTENANCE FACILITY PROJECT UNDERSTANDING We understand the proposed construction will be comprised of a 10,775 sq ft new maintenance facility building, with a 1,398 sq ft mezzanine, and associated site work. We also understand that the structures will be comprised of cast -in-place concrete foundations and slabs, and single -level structural masonry structure with the roof structure comprised of structural steel framing. Site grading will require the placement and compaction of various cut and fill ranging 1-4 feet depending on the location. Exterior work will include concrete paving over pit run and crushed aggregate base course as well as various utility improvements. SCOPE OF WORK At the time of the preparation of this Proposal, STRATA did not have the opportunity to review the contractor's construction schedule. Therefore, we are only able to provide a preliminary fee estimate which may be subject to change due to construction schedule, workforce, weather, or jurisdictional requirements which cannot be anticipated. We have based our attached Task Order 10163 Special Inspection And Testing Services Meridian WWTP Maintenance Facility Page 1 of 8 STRATA Preliminary Fee Estimate (Estimate) on certain assumptions; specifically, the quantity of site visits for various construction aspects which we believe are consistent with current construction practices. These assumptions are detailed on the corresponding Estimate. We request the opportunity to review this document as it becomes available, and make appropriate modifications to our Estimate. On this project we anticipate STRATA's primary scope of services will consist of the following activities: 1) Observation and compaction testing during soil improvements, site grading, utility trench backfill and earthmoving activities. 2) Special inspection of the placement of reinforcing steel and items embedded in concrete. 3) Sampling and quality control testing of concrete. 4) Special inspection during placement, consolidation, and curing of concrete. 5) Special inspection and testing of structural load bearing masonry construction. 6) Structural steel construction, including special inspection of field welding, high strength bolt installations and tightening, and steel fabrication quality assurance. 7) Special inspection during the installation of post -installed -anchors (chemical epoxy or expansion type anchors). S) Sampling and laboratory testing of various construction materials (i.e. concrete, soils, aggregates, grout, etc.). STRATA has assigned Mr. Don Hill as our Project Manager to provide supervision and technical oversight of our services. Mr. Hill will be responsible to interact with your designated project representative to coordinate and schedule our special inspection, field observation and laboratory testing services. Staff assignment will be dependent on the nature of the testing required. Our intention is to assign a primary special inspector with multiple certifications and experience that will provide the majority of the required testing; thereby increasing the continuity, effectiveness and efficiency of our services. This individual will be supported by other testing professionals as dictated by the project schedule and testing requirements. Pre -Construction Meetings STRATA's Project Manager will attend a pre -construction conference with you, appropriate subcontractors, and the local jurisdictional agency to review the inspection and materials testing requirements for the project and to establish report distribution protocol. If requested, we will also attend subsequent project meetings with the contractor and subcontractors for specific construction applications (i.e. earthwork, concrete, and structural masonry) as you deem necessary. Earthwork Observation and Testing Services We will provide field professionals to perform observation and compaction testing services during site grading, placement and compaction of structural fill, backfilling of utility trenches, soil improvement activities, placement and compaction of subgrade and aggregate base material. Compaction testing will generally be performed as required by the project specifications. Our personnel will sample on-site and imported materials used for backfill and transport these samples to our laboratory for appropriate testing. These visits will be provided on a periodic basis which will be coordinated with the contractor's project superintendent. Task Order 10163 Special Inspection And Testing Services Meridian WWTP Maintenance Facility Page 2 of 6 STRATA Special Inspection of the Placement of Reinforcing Steel and Embedded Items We will provide and International Code Council (ICC) certified special inspectors to verify the placement of reinforcing steel and embedded items prior to the placement of concrete. Our inspection of reinforcing steel and embedded items will include verification of type, grade, size, cleanliness, lap splice, clearance, coverage, general placement of reinforcing steel/embedded items and conformance with project plans and specifications. Deficiencies will be reported to the contractor for correction prior to the placement of concrete. If deficiencies are uncorrected, we will notify you and other designated persons of non-compliant conditions. Concrete Observation and Testing We will provide special inspectors certified by the ICC to observe concrete placements and sampling and field testing. Our field services include testing for slump, temperature (concrete and ambient), air content, verification of mix design as indicated on the batch tickets, and fabricating of compressive strength test specimens, as required by the project specifications. Concrete sampling and field-testing is conducted by personnel certified by the American Concrete Institute (ACI) as a Concrete Testing Technician — Field Grade I. Please refer to the Estimate for anticipated amount of concrete test cylinders on this project. We have estimated these quantities based on IBC specifications, which require 1 composite sample and 1 set of compressive strength specimens for every 150 cubic yards (c.y.) placed. We will test 1 concrete compressive strength specimen at 7 days, 3 at 28 days, and a specimen will be held in reserve pending successful results of the 28 -day tests. STRATA will notify those person(s) identified by you via telephone should the test results of the 7 -day test achieve less than 70 percent of the specified compressive strength (f'c), or if the 28 -day test results do not achieve f'c. Hold specimens will be discarded if the 28 -day tests achieve f'c, unless we receive specific instructions otherwise. Results of concrete compressive strength testing will be distributed via email to the distribution list established during the pre - construction meeting, unless directed otherwise. We based this Proposal on the assumption that compliance testing of other materials (i.e. aggregates, cement, etc.) will not be required. Therefore, we have not included these activities in our anticipated scope of services. If it becomes necessary, we can provide these services for an additional fee. Masonry Observation and Testing STRATA will provide an ICC -certified Special Inspector to provide continuous special inspection during the placement of grout and during the sampling of mortar, grout, and/or concrete masonry units (CMU). Also, we will provide periodic special inspection during the placement of CMU, mortar, reinforcing steel, and items embedded in masonry. We will also sample and test construction materials including: masonry prisms, grout, and mortar for compression testing for each 5,000 SF of masonry construction, as required by the project documents and applicable codes. We will deliver these samples to our laboratory for appropriate testing. We have based our Preliminary Fee Estimate on the assumption that the contractor will utilize low -lift grouting techniques during construction of the CMU walls. The actual cost of CMT and special inspection may vary depending on grout placement method. Task Order 10163 Special Inspection And Testing Services Meridian WWTP Maintenance Facility Page 3 of B STRATA Structural Steel Field Welding Observation We will provide special inspectors certified by either the American Welding Society (AWS-CWI) or ICC to observe welding operations during structural steel erection and connection at the project location. We accomplish this on a periodic basis as dictated by the approved drawings and applicable codes. Our services include the observation of welder certifications, material identification, joint fit -up, pre/post-weld heat treatment, and general compliance of structural steel construction to the project requirements and applicable codes. Structural Steel High -Strength Bolting Observation and Testing STRATA will also provide an ICC certified special inspector to observe the installation and tightening of High Strength Bolts as dictated on the approved project plans. We will perform tension testing of bots using a Skidmore Bolt Tension measuring device to establish compliance with the project requirements. In addition to a visual inspection to verify the proper tightening and detachment of bolt -spline tension indicators, we will perform torque testing on a minimum of 10% of the bolt connections. Also, we will provide continuous basis to observe any bolts tightened using the turn -of -nut method. In -shop Structural Steel Fabrication Inspection STRATA anticipates the need for in -shop structural steel fabrication inspection based on our review of the project specifications. We will provide a special inspector certified by either the American Welding Society (AWS-CWI) or ICC to observe the in -shop fabrication process. This will be done on a periodic/continuous basis as dictated by the approved drawings and applicable codes. Our services include the observation of welder certifications, material identification, joint fit -up, pre/post-weld heat treatment, and general compliance of structural steel construction to the project requirements and applicable codes. STRATA can also provide non-destructive examination (NDE) (i.e. PT, MT, UT) of welded connections if required, however we do not anticipate the need for NDE of welded connections for the in -shop fabrication portion of this project and have not included this service in our estimated budget. Post -Installed Anchors (Epoxy/Expansion Anchors) We will provide an ICC -certified special inspector to observe the installation of reinforcing steel/anchor bolts using a chemical epoxy, as specified. Our field services will include verification of the size, depth, spacing, and cleanliness of holes to receive the reinforcing steel/anchor. We will also verify adherence with the manufacturer's specification for the chemical epoxy anchor. If required, we can perform pull/load/torque-testing services of reinforcing steel bars/anchor bolts installed using the above referenced applications as part of our scope of services. Laboratory Testing We anticipate that compliance testing of soil (moisture -density relationship curve, gradation) and concrete (compressive strength), will be required during construction. Technical Management & Reports Our Project Manager reviews the daily field reports generated by our field staff during construction. Items found in non-compliance with the project requirements are brought to the immediate attention of the construction superintendent. If the situation is not corrected, we will subsequently notify the designated design professional and those designated by the client. As re -inspection items can have a serious impact on our budget, our Project Manager will review Task Order 10163 Special Inspection And Testing Services Meridian WWTP Maintenance Facility Page 4 o18 STRATA the daily field reports to monitor items requiring re -inspection and the hours involved in these re -inspections. Upon project completion, we will provide a final summary report to document the materials testing and special inspection services conducted. We have assumed that our standard invoicing format issued on a monthly basis with no supporting documentation will be acceptable for this project. If supporting documentation or specialized invoicing is required, additional administrative time may be required to accommodate your request. TIME OF COMPLETION and COMPENSATION SCHEDULE Strata will provide our services on a time -and -expense basis in accordance with the rates established in the attached Estimate. These rates will remain in effect through the duration of the project. Overtime for our field staff will incur a time and one half fee in addition to our standard rate for time in excess of 8 hours during one day (Monday through Friday), non- standard construction hours (before 8:00 AM or after 5:00 PM), and all hours on weekends and holidays. This Proposal excludes the cost of any equipment (i.e. scaffold, scissor lifts, telescopic booms, ladders, trench shoring) to gain access to any area requiring inspection or sampling of materials. In order to better service your project, Strata requests that you please schedule at least 24 hours in advance of the needed service.
