B. Procedures

1. General: Contractor shall submit to the City, details of the installed tests and inspection procedures he proposes to adopt for testing and start-up of all equipment to be operated singly and together, except when such procedures have been covered in the technical Specifications.

The procedures shall be divided into two distinct stages: Preoperation checkout and clean water test. Testing procedures shall be designed to duplicate, as nearly as possible, all conditions of operation and shall be carefully selected to ensure that the equipment is not damaged. Once the testing procedures have been reviewed by the City, the Contractor shall produce checkout, alignment, adjustment and calibration signoff forms for each item of equipment to be used in the field by the Contractor and the City jointly to ensure that each item of electrical, mechanical, and instrumentation equipment has been properly installed and tested. The Contractor is advised that failure to observe these precautions may place the acceptability of the subject equipment in question.

2. Preoperation Checkout: The installed tests and inspection procedures shall incorporate all requirements of these Specifications and shall proceed in a logical, step-wise sequence to ensure that all equipment has been properly serviced, aligned, connected, calibrated and adjusted prior to operation. Preoperation checkout procedures shall include, but not necessarily be limited to:
a. Piping system pressure testing and cleaning as specified in Division 15.
b. Electrical system testing as specified in Division 16. c. Instrumentation system testing as specified in Division 17. d. Alignment of equipment.
e. Preoperation lubrication.

3. Clean Water Test: Clean water shall be employed for the testing of all liquid systems except gaseous and oil. Test media for these systems shall be either the intended fluid or a compatible substitute. The equipment shall be operated a sufficient period of time to determine machine operating characteristics, including temperatures and vibration; to observe performance characteristics; and to permit initial adjustment of operating controls. When testing requires the availability of auxiliary systems such as electrical power, compressed air, liquefied petroleum gas, control air, or instrumentation which have not yet been placed in service, the Contractor shall provide acceptable substitute sources, capable of meeting the requirements of the machine, device or system, at no additional cost to the City. Disposal methods for test media shall be subject to review by the City.

If under test, any portion of the work should fail to fulfill the Contract requirements and is adjusted, altered, renewed or replaced, tests on that

The Contractor shall pay to the City all reasonable expenses incurred by the City as a result of repeating such tests.

Once simulated operation has been completed, all machines shall be rechecked for proper alignment, realigned, if necessary, and doweled in place. All equipment shall be checked for loose connections, unusual movement or other indications of improper operating characteristics. Any deficiencies shall be corrected to the satisfaction of the City. All machines or devices which exhibit unusual or unacceptable operating characteristics shall be disassembled and inspected. They shall then be repaired or removed from the site and replaced at no cost to the City.

Unless otherwise specified, the Contractor shall provide, at no expense to the City, all power, fuel, compressed air supplies, labor and all other necessary items and work required to complete all tests and inspection specified herein. The Contractor shall provide, at no expense to the City, temporary heating, ventilating and air conditioning for any areas requiring it in the case where permanent facilities are not complete and operable at the time of installed tests and inspections. Temporary facilities shall be maintained until permanent systems are in service.

4. Operational Testing: After completion of all installed testing and certification by the City that all equipment complies with the requirements of the Specifications, the Contractor shall fill all process units and process systems, except those employing non-potable water, domestic water, oil or chemicals, with potable water. All non-potable water, domestic water, oil and chemical systems shall be filled with the specified fluid.

Upon completion of the filling operations, the Contractor shall circulate water through the completed facility for a period of not less than 96 hours, during which all systems shall be operated as a complete facility at various loading conditions, as directed by the City.

shall be used if necessary to meet all minimum requirements shown in the table. Failure to meet these conditions shall be considered failure of the concrete.

5. The strength level of the concrete will be considered satisfactory if the averages of all sets of three consecutive strength test results equal or exceed the required strength and no individual strength test falls below the required strength by more than 500 psi. Where an individual strength test falls below the required strength by more than 500 psi, the District Representative shall have the right to ask for additional curing of the affected portion followed by cores taken in accordance with ASTM C 42 and ACI 318, all at the Contractor's expense. If the additional curing does not bring the average of three cores taken in the affected area to at least the strength specified, the District may require strengthening of the affected portions of the structures by means of additional concrete or steel or replacement may be required of those affected portions, all at the Contractor's expense.

6. In-place concrete represented by a compressive cylinder Strength test failing to meet the specified 28-day compressive strength shall be removed from the work at no cost to the District. Also, the Contractor shall at its own expense make any corrective changes in the mix deemed necessary by the District. The changes in the mix proportions or placement procedures shall be submitted to the District prior to the placement of any additional concrete subsequent to a failing compressive strength test.

7. As an alternative to the removal of concrete represented by a failed cylinder compressive strength test and subject to the approval of the District, the concrete represented by the failed compressive strength cylinder test or tests may be cored in place. The corings shall by completed no later than 10 days from notification of failure by the District.

The cores shall be taken by the Contractor in the presence of the District Representative and tested at the Contractor's expense in accordance with ASTM C 42 by a certified laboratory acceptable to the District. The cores shall be 4 inch diameter (min.) unless otherwise directed by the District Representative. At least three cores shall be taken in each area represented by a failed 28-day concrete compressive strength cylinder test. Unless otherwise directed by the District Representative, the cores shall be tested wet following a 40-hour submergence. If each core tests at least 85 percent or greater than the specified 28-day compressive strength, the concrete represented may be accepted provided the Contractor accepts the payment provisions stated below. Concrete represented by failing core tests shall not be paid for and shall be removed by the Contractor from the work at no cost to the District.

8. Payment to the Contractor for concrete accepted by the District based on core test results but represented by failing compressive cylinder test results shall be reduced as follows:

a. When the result of a single compressive cylinder strength test is less than the specified 28-day compressive strength but 95 percent or more of the 28-day compressive strength, the Contractor shall pay the District $15 per cubic yard for each inplace cubic yard of concrete represented by the deficient compressive strength cylinder test as determined by the actual sampling interval; and.
b. When the result of a single compressive strength cylinder test is less than 95 percent of the specified 28-day compressive strength but is acceptable based on core test results taken in accordance with Section 1.4, E(5), the Contractor shall pay the District $20 per cubic yard for each in-place cubic yard of concrete represented by the deficient compressive strength cylinder test as determined by the actual sampling interval.

F. Shrinkage Tests

1. Drying shrinkage tests shall be provided by the Contractor for the trial batch specified in Section 2.4 and during construction to insure continued compliance with these specifications.

2. Drying shrinkage specimens shall be 4-inch by 4-inch by 11-inch prisms with an effective gage length of 10 inches, fabricated, cured, dried and measured in accordance with ASTM C 157 modified as follows:
specimens shall be removed from molds at an age of 23 +/- 1 hours after trial batching, shall be placed immediately in water at 70 degrees F +/- 3 degrees F for at least 30 minutes, and shall be measured within 30 minutes thereafter to determine original length and then submerged in saturated lime water at 73 degrees F +/- 3 degrees F. Measurement to determine expansion expressed as a percentage of original length shall be made at age 7 days. This length at age 7 days shall be the base length for drying shrinkage calculations ("0" days drying age). Specimens then shall be stored immediately in a humidity control room maintained at 73 degrees F +/- 3 degrees F and 50 percent +/- 4 percent relative humidity for the remainder of the test. Measurements to determine shrinkage expressed as percentage of base length shall be made and reported separately for 7, 14, 21, and 28 days of drying after 7 days of moist curing.

3. The drying shrinkage deformation of each specimen shall be computed as the difference between the base length (at "0" days drying age) and the length after drying at each test age. The average drying shrinkage deformation of the specimens shall be computed to the nearest 0.0001- inch at each test age. If the drying shrinkage of any specimen departs from the average of that test age by more than 0.0004-inch, the results obtained from that specimen shall be disregarded. Results of the shrinkage test shall be reported to the nearest 0.001 percent of shrinkage. Compression test specimens shall be taken in each case from the same concrete used for preparing drying shrinkage specimens.

These tests shall be considered a part of the normal compression tests

Unless otherwise specified, base plates, mounting blocks and sole plates weighing less than 1,000 pounds shall be leveled on steel blocks 4 inches square and 1-1/2 inches thick with a hole drilled in the center for the anchor bolt, placed under the base at every anchor bolt. Leveling shall be by use of mounting blocks machined flat on all horizontal surfaces and measuring not less than 4 inches wide horizontally and shims that shall extend not less than three inches beyond the base of the equipment. Mounting blocks shall be coated with a light oil just prior to beginning the leveling and grouting work. Using precut steel shims coated with a light oil between the base and the steel blocks at the anchor bolts, the Contractor shall level the equipment base plates, sole plates or mounting blocks against the anchor bolt nuts (finger tight only) to a maximum tolerance of 0.0005 in/ft or as otherwise required by the equipment manufacturer, if more stringent. Mounting surfaces for equipment shall be coplanar within 0.002 inch in any direction. The shims shall be placed so the tabs on the shims are easily accessible. A minimum of four shims per anchor bolt shall be used. The total shim thickness at each anchor bolt shall be at least 0.015 inch. Leveling shall be against anchor bolts prior to final grouting.

2. The Contractor shall level the equipment against the anchor bolt nuts to a maximum tolerance of 0.002 in/ft or as otherwise required by the equipment manufacturer, if more stringent. Leveling equipment shall be precision surveying equipment. Machinists’ spirit levels will not be permitted for leveling purposes for any base plate or equipment foundation with a plan dimensions greater than 4 feet.

3. Leveling nuts may be used for mounting equipment weighing less than 500 pounds. The Contractor shall level the equipment against the anchor bolt nuts to a maximum tolerance of 0.0005 in/ft or as otherwise required by the equipment manufacturer, if more stringent. Anchor bolt nuts shall be only finger tight during the leveling process. Wedges will not be allowed and under no circumstances shall shims be used as permanent support under base plates, sole plates or leveling plates.

E. Grouting

1. Grout forms shall be built of minimum of 3/4-inch thick waterproof plywood and shall be securely braced (minimum brace size shall be 2 inches x 4 inches). Forms shall provide a minimum of 2-inch hydrostatic head above the final elevation of the grout to assist in flow during installation.

2. Forms must be coated with three coats of paste wax on all areas that will come in contact with the grout to prevent the grout from bonding to the forms. Forms shall be waxed before assembly to prevent accidental application of wax to surfaces where the grout is to bond. Before any forms are installed, all concrete surfaces that will contact epoxy grout shall be free form any foreign material, such as oil, sand, water, grease,

etc. Forms shall be liquid-tight. Any open spaces or cracks in forms, or at the joint between forms and the foundation, shall be sealed off, using sealant. All outside vertical and horizontal edges of the grout shall have 45-degree chamfers. Blockouts shall be provided at all shimming and leveling nut positions to allow removal of shimming equipment after the grout has cured. Jackscrews shall be coated with a light oil or other acceptable bond-breaking compound.

3. The 45-degree chamfer strip shall be located at the final elevation of the grout. The final elevation of the grout on base plates with exposed Ibeam or C-channel supports shall be at the top of the lower support flange. The top of the grout, on base plates with solid sides and sole plates, shall be 1 inch above the bottom of the base plate or the underside of the sole plate. The grout’s final elevation shall not be so high as to bond the anchor bolt nut and washer.

4. The epoxy resin and hardener shall be mixed in accordance with the grout manufacturer’s recommendations. Aggregate shall be slowly added to the mixer one bag at a time. The grout shall be mixed only long enough to wet out all the aggregate. Grout shall be placed at the center of one end of the base plate or sole plate and worked toward the ends in such a manner as to force the air out from beneath the base plate or sole plate and out the vent holes, to eliminate voids. The grout shall be placed in a manner that avoids air entrapment using a head box to pour grout into the grout holes. When the head box is moved to the next grout hole, a 6-inch high standpipe shall be placed over the grout hole and filled with grout. The Contractor shall exercise care to never allow the grout to fall below the base plate level once the grout has made contact with the base plate. Grout placement shall be continuous until all portions of the space beneath the base plate or sole plate have been filled. Subsequent batches of grout shall be prepared so as to be ready when the preceding batch has been placed. Under no circumstances shall the grouting operation be halted because of lack of grout mix. After the entire base plate is full, 6-inch high standpipes shall be maintained over each grout hole, to continue purging of air. When the grout has started to take an initial set (determined by a noticeable increase in temperature and no flow of grout at the vent holes) the standpipes shall be removed and excess grout cleaned from all surfaces.

5. A grout sample shall be taken for each piece of equipment to be grouted.

The sample shall be placed in a cylinder of sufficient size to yield three 2- inch x 2-inch x 2-inch test samples. The samples shall be tagged with the equipment number and ambient temperature at the time of placement.

The samples shall be tested in accordance with the manufacturer’s recommendations. Once the epoxy grout cylinder has been completely filled, it shall be placed next to the foundation of the equipment being grouted and allowed to cure for 48 hours. After 48 hours, the test cylinder shall be tested in accordance with the grout manufacturer’s recommendations by an independent testing laboratory. The results shall be reported directly to the Engineer. Forms shall be removed only after the grout has cured sufficiently and upon specific permission from the Engineer.

F. Completion: Upon acceptance by the Engineer and the grout has reached sufficient strength, the shims shall be removed, and leveling nuts or jack screws backed off to allow the grout to fully support the equipment base, leveling block or sole plate. Removal of extended shimming material (direct mounted base plates weighing 1,000 pounds or less) shall be by sledge hammer, taking care not to damage the grout. Once shims have been removed, or jack screws backed off, the anchor bolts shall be torqued, using calibrated indicating torque wrenches, to develop the full clamping force required by the equipment manufacturer. Anchor bolts shall be torqued in increments of not more than 25 percent of final value in an alternating pattern to avoid stress concentration on the grout surface. Pockets for access to shims, or leveling nuts shall be filled with grout mix and pointed after the anchor bolts have been torqued to final values.
