FROM: Dave STRINGER / CFC52/01 TO: Gary DIEDE / CFC52/01 CC: Marc ENGEMOEN / CFC52/01 David KLOCKEMAN / CFC52/01 Part 2. Contents.-2. Gary, I have talked with Bill Albretch about his Fairway Five Development and the differences with the report prepared by Empire and Aguirre's reveiw of the same. I told him that we as the City were discussing the possibility of having a more in-depth study done to more accurately determine the situation. Bill was somewhat concerned but, not entirely opposed. His concern is to get out from under this development. Bill wants to futher discuss options other than an extended warranty and also a time frame for completion. I have scheduled a meeting for Wed. Jan. 4, 1989 in the Engineering conference room at 10:00, between Bill, Ben Connell (the contractor) and myself. Do you have time to attend?

Boardwalk, Suite 250 Fort Collins, Colorado 80524 RE: Fairway Five Estates Dear Mr. Albrecht: The intent of this letter is to address some concerns I have regarding the installation of public improvements in the Fairway Five Estates Planned Unit Development. Recently, many areas of street settlement have begun to appear. The major settlements seem to be around manholes, valve boxes and sanitary service laterals with some settlement of water service trenches. I am concerned with the amount of settlement which has already occurred. It is quit extensive for a development less than one year old, and further damage will occur in the future from additional settlement. It is my opinion that what we are seeing today is just the beginning, and street settlements will continue. In reviewing our files I cannot find any record of density tests for the underground utility work, street, curb, gutter, or sidewalks. The only test results we have are for the density and gradations of the asphalt pavement and concrete curb, gutter and sidewalk. Were tests taken on the backfill of the water and sewer work? If so, were they sufficient to guard against the possibility of major settlement? As you recall, the City allowed construction of this project to begin prior to the approval of the utility plans with the understanding that Albrecht Companies would be responsible for the performance of its contractors as it relates to the construction of the public improvements. Based upon what is currently taking place in this development, the City will not accept any of the public improvements in Fairway Five Estates development until such time as it is brought up to an acceptable City standard. Based upon the present condition of streets in this development, we can only assume the worst. Therefore, we feel non-destructive testing is required to determine the adequacy of the pavement and subgrade structure. Please call us to set up a meeting so that we can discuss the City's requirements for this non-destructive testing. 300 LaPorte Avenue • P.O.

This method is fine, provided the trench backfill is re=TPacted prior to replacing the asphalt. However, as I stated previously, the probability of additional settlement is great and we need to be satisfied that there will not be any further street damage due to utility trench failure. It is my recommendation that the more severe areas be repaired, then hold off on any further repairs until the total extent of the problem can be determined. In addition, it is not in the City's best interest to allow a less then one year old street to be cut and patched in several locations. This method only increases our maintenance costs. Therefore, a minimum 3/4 inch plant mix seal coat or what may be required through the non-destructive tests, will be required on all streets that may need repair. Please contact me as soon as possible on what decisions and actions you intend to take which will address our concerns regarding the streets and settlement problems in this development.

After reviewing the report prepared by Empire Iaboratory and through much discussion with our geotechnical consultant (Aguirre Engineering), we find this situation to be more complex then what was originally anticipated. It is our contention that several questions remain unanswered. Particularly, (1) will there be additional settlement in the future? (2) why are the laboratory density tests significantly higher than what is normally encountered in the field, and (3) there appears to be some inconsistencies in the swell test results. However, without performing extensive destructive testing, the answers to these questions will remain unanswered. In lieu of additional tests, the City is willing to accept the recommendations as stated in Empire's report with the following conditions: A. In the areas which currently exhibit signs of settlement the limits for removal, recompaction, and asphalt replacement, will be determined by the City. B. Empire Labs is to be retained to test the backfill material and the depths of removal. 3110 LaPorte avenue • I'O. R(,\'S0 • I„ t Q,IGm.

If a soil backfill is used, then moisture/density tests shall be taken at maximum one foot intervals and shall meet the recommendations specified on pages 4 through 6 of the report. D. The street system is to be maintained for a period of five (5) years. E. A performance bond is to be posted for the monitoring period. We agree in part with the section of the report concerning the monitoring Of future settlement. Except, we want the asphalt surface to be installed at the time of the trench backfill restoration. Additionally, we are requiring that the entire street system for this development, be monitored for future settlement. It is our belief that without sufficient data (time rate of consolidation test), the statement that future settlement will be minimal is inaccurate. Therefore, I request that these streets be monitored at your expense for a period of five (5) years, and to ensure that future settlements will be corrected, we must ask for a performance bond to be in full force and effect for the monitoring period. Lastly, the report stated that some movement of manholes from soil expansion was noted . But, it failed to address any reconmeridations for correcting the situation and the swell tests do not indicate extensive swell potential. In talking with Dean Hill of the water district, there was no evidence of the manholes rising when he performed a visual inspection of the system last week. However, to protect their interest, we must request the extended warranty and performance bond also include the underground utility system. I appreciate the fact that you have been willing to work with the City in correcting this situation and hopefully, the recommendations as outlined in Empire's report will solve the problem without any additional expense. Again, let me thank you for your time, patience and interest, in getting these streets into an acceptable condition. If you have any questions, Please contact me at 221-6605.

Through our review of the area and evaluating the amount of street settlement which has already occurred, additional settlement is probable. Therefore, once the immediate repairs are made, we request that an extended warranty period of five years with an escrow account be established. In order to address your concern of what an appropriate escrow amount would be, I used 1700 feet of trench length including services. This is the approximate length of sewer trench currently under the asphalt pavement. Following is a breakdown of what was used to arrive at what we feel is an acceptable escrow amount: Remove existing asphalt and excavate 3 feet wide to a depth of 4 feet - 760 cubic yards. Recompact trench backfill - 760 cubic yards (using in situ material). Install and compact 9 inches of class 5 roadbase - 250 tons. Install 3 inches of grading E asphalt pavement - 160 tons. 300 I..)Portc .-Avenur • 1'10� Bov BSI) • Fort Collins. CO 80522-0-,50 • (303) 221-6505 Mr. William Albrecht Page Two Based upon construction costs associated with our projects this year, I estimate the cost for the work as outlined to be $25,000 provided 100% of the trenches were to fail. However, this is unlikely, so for purposes of establishing an escrow amount I've used a figure of 60% trench failure. Using the 60% number as a figure for potential settlement, the amount to be escrowed is $15,000.00. These monies can be in the form of a bond, letter of credit, cash escrow or some sort of monetary guarantee acceptable to the City which will coincide with the extended warranty period.
