b. Pressure Testing and Pressure Washing. The pressure-test and
pressure-washing records should show the hole number, location, elevation,
depth of hole, zone, stage or packer setting as appropriate, and the starting
and completion times of all testing and washing. The rate and pressure at
which water is injected must be shown. If water vents from other holes
their numbers and locations should be given. If connecting to a hole is a pay
item and more than one connection per test is made, all the circumstances
involved should be entered in the record. Information on the water table
should be included in the pressure-test book or in the drilling records or
both. A separate notebook should be used to record all pressure-test and
p r e s s u r e - w a s h i n g data, and it also should be available to the grouting
inspector.
c. Grouting. The grouting record should be more elaborate than the
other records described because grouting is a more complicated operation
and the grouting log not only serves as a record of the pay quantities, but be-
cause it also is the only detailed record of the grouting treatment in exist-
e n c e . The interpretation of the grouting logs may have a major bearing on
decisions for further treatment either during or after construction. The log
of grouting operations must contain the hole number, location, elevation, data
on inclination, position in the order of grouting (primary, first intermedi-
ate, etc.), information on the portion of hole being grouted (depths and/our
elevations, and stage or zones), and the date and shift the work was done.
The log should show the starting and completion times, the time mixes were
changed, the time water was injected, and the time of delays and the reasons
t h e r e f o r . Pressures, injection rates, location of leaks, and any other infor-
mation pertinent to the understanding of the operation should be given. The
pay quantities of all ingredients should be shown clearly. If payment is by a
volume or weight unit for both placing and furnishing the ingredients, each
unit placed is also a unit furnished and must be paid for under both items.
If leftover grout from the last batch mixed for any hole is carried forward to
the next hole, it should be accounted for in the log for the new hole. Leftover
grout that is allowable waste as a result of cessation of grouting operations
is paid only under the item or items for furnishing ingredients., since it was
not placed. There are many acceptable forms for grouting logs. The sample
log in appendix II is one of several forms of grouting logs that have been
used for portland-cement grouting. It illustrates how an accurate accounting
of all grout mixed can be made. The record of each batch of grout and its
rate of injection provides detail that is insurance against miscounting batches
and provides data that can be readily scanned for indications of abnormalities
such as lifting. It also permits a supervisor to second guess the inspector
and to evaluate his judgment.

RECORDS FOR FUTURE REFERENCE. In addition to records that must
be kept to administer the contract, records should be kept for future refer-
e n c e . The field notebooks are the basic "as-built" records. However, other
summary- type records are also desirable. If quantities are summarized by
