Thank you for the opportunity to submit this proposal. If this proposal is satisfactory, would you please sign the white copy of the enclosed proposal acceptance sheet and return it to us. We will consider receipt of a signed copy of this proposal as our official notice to proceed. We look forward to working with you on this project.

P tettne Man er o ical Services DPS /ts Attachments: Standard Fee Schedule Proposal Acceptance Sheet 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) A.

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) A.

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 LINEAR FEET, PER 1' LIFT) A.

Such persons or firm to have complete authority to transmit instructions, receive information and data, interpret and define CLIENT's policies and decisions with respect to THE PROJECT, to take action to prevent irrevocable entry of those materials in noncompliance until the issue at question can be resolved: and to order, at CLIENT's expense, such technical services as may be requested of ALPHA. 4. Advise ALPHA sufficiently in advance of any operations so as to allow for assignment of personnel by ALPHA for completion of the required services. Such advance notice shall be in accordance with that established by mutual agreement of the parties. 5. Direct THE PROJECT contractor, either by the Construction Contract or direct written order to: (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. 2. ALPHA is not authorized to supervise, alter, relax, enlarge or release any requirement of THE PROJECT specifications or other contract documents nor to approve or accept any portion of the work. unless specifically authorized in writing by CLIENT or his authorized representative. ALPHA shall not have the right of rejection or the right to stop the work, except for such periods as may be required to conduct the sampling and testing covered by the Agreement. ARTICLE 5. FIELD MONITORING AND TESTING: CLIENT agrees that ALPHA will be expected to make onsite observations appropriate to the construction stage. The CLIENT further agrees that ALPHA will not assume responsibility for the contractor's means, methods, techniques, sequences or procedures of construction, and it is understood that the services provided by ALPHA will not relieve the contractor of his responsibilities for performing the work in accordance with the plans and specifications. The words ''inspection" or "control" are used to mean periodic observation of the work and the conduct of tests by ALPHA to verify substantial compliance with the plans, specifications and design con- cepts. Continuous monitoring by our employees does not mean that ALPHA is approving placement of materials. ARTICLE 6.
