General Terms and Conditions
ESTIMATED TESTING SCHEDULE
The following is our estimate of the number, type and cost of
anticipated construction materials testing for the project
referenced previously. This estimate of the expected testing was
developed based on project plans. Testing frequencies are based on
current available information in our office, compiled from City
standards, geotechnical reports or locally accepted standards. It
should be recommended that variations in construction schedules)
weather, amount of retesting, additional testing requested by our
client, etc., could result in differences between the actual and
estimated testing costs. Although efforts will be made to maintain
the testing costs within the estimated amount, charges will be
computed based on actual services rendered. Testing services
proposed herein do not include full -time personnel on site and any
form of project supervision. It is our understanding that testing
will be scheduled by the client, or his representative, and ALPHA
TESTING, INC. does not assume the responsibility for assuring all
required tests are performed. If desired, ALPHA could monitor
testing frequencies and locations during the progress of the work
to assure the required testing is performed, at an additional cost.
I. SITE PREPARATION, FILLING AND BACKFILLING
Based on our understanding of the project, field density
testing is required on the subgrade and fill materials placed.
It is estimated that an engineering technician could be
required on site for about 185 hours to perform approximately
630 field density tests. In addition, the technician could
obtain approximately 6 soil samples for laboratory proctor
analysis. (ASSUMED 1 FDT EACH 300 L.F. FOR PAVED AREAS)

SUBTOTAL .................... .....................$10,560.00
A /I
II. MECHANICAL LIME STABILIZATION
It is our understanding that approximately 1,285,340 square
feet of subgrade would be mechanically lime stabilized. We
have estimated that our engineering technician could be
required on -site for about 103 hours to perform approximately
147 field density tests. In addition, the technician could
obtain approximately 8 soil samples for laboratory proctor
analysis. (ASSUMED ON 1 FDT EACH 300 LINEAR FEET)

IV. UTILITIES
Based on our understanding of the project, field density
testing is required on the backfill material placed. We have
estimated that approximately 12,005 linear feet of reinforced
concrete pipe storm drains would be excavated and installed.
In addition, about 13,130 linear feet of water lines, and an
estimated 2,350 linear feet of sanitary sewer lines would be
placed. We have estimated that our engineering technician
could be required on site for approximately 237 hours to
perform approximately 619 field density tests. In addition
the technician could obtain approximately 8 soil samples for
laboratory proctor analysis. (ASSUMED ON 1 FDT EACH 300

(a) Secure and deliver to ALPHA, without cost to ALPHA, preliminary representative samples of those materials he proposes to use which require testing, together
with any relevant data of the materials.
(b) Furnish such casual labor and all facilities needed by ALPHA to obtain and handle samples at THE PROJECT and to facilitate the specified inspection and tests.
(c) Provide and maintain for the use of ALPHA, adequate space at THE PROJECT for safe storage of equipment and proper curing of test specimens which must
remain on THE PROJECT site prior to testing.
ARTICLE 4. GENERAL CONDITIONS:
1. ALPHA, by the performance of services covered hereunder, does not in any way assume, abridge or abrogate any of those duties, responsibilities or authorities
with regard to THE PROJECT which, by custom or contract are vested in THE PROJECT architects, design engineers, or any other design agencies or authorities.
