(TKDA) on Duluth Avenue improvements. On May 2, 1988, City Council approved authorizing the City to enter into a with TKDA on performing engineering for Duluth Avenue improvements. The outlined the services to be provided three (3) categories as follows: a motion contract services contract in the Part I Part II Part III - Right of Way Acquisition Plans Phase Construction Engineering with each category, the engineering fees were to be completed on an hourly basis with the total cost of each category not to exceed a maximum amount without further authorization from the City. The hourly basis for engineering services was agreed to due to the unknowns and complexity associated with this project. The maximum amount for construction engineerin~ services without further authorizatlon per the contract is $12,000.00. Construction engineering fees were received in 1989 and 1990 and the total paid to date is $13,640.66. It was detected after the AU9ust engineering service invoice that the maXlmum amount of $12,000.00 was exceeded and required further Council authorization. The September and October engineering service invoices in the amounts of $133.46 and $127.3l, respectively, have not been paid and will be 4629 Dakota St. S.E., Prior Lake, Minnesota 55372 / Ph. (612) 447-4230/ Fax (612) 447-4245 An Equal Opportunity/Affirmative Action Employer submitted for payment if Council authorization is received. Additional engineering service invoices will be forthcoming to complete the project and these invoices are estimated to be $187.10 and $266.04 for the November and December billings. The total construction engineering amount for this project is projected to be $14,354.57. City engineering staff will inspect the remaining work and other contract administration duties to limit the construction engineering expenditures to this amount. DISCUSSION: Most of the Duluth Avenue improvements were constructed in 1989/1990 except for the final bituminous wearing course which will be placed in 1991. Construction of these improvements over this period of time was necessary to properly construct the roadway over an area of poor soils. A period of time was needed to consolidate the soils so as to minimize future possible settlements of the roadway embankment. Initially, the project design was to be completed in the 1989 construction season. The consolidation of the underlying poor soils was not obtained in 1989 and the project was extended to the 1990 and 1991 construction seasons. This additional length of construction time required additional construction engineering services not anticipated if the project would have been completed in 1989. During the course of construction, storm sewer system modifications were necessary to properly drain adjacent properties and to repair the storm sewer system on CSAH 21 prior to connecting the Duluth Avenue storm sewer system. These modifications were unknown at the time of preparing the plans and required extra construction engineering services. Realignment of storm sewer lines was necessary and required extra engineering and plan revisions to be done. The repair of the storm sewer under CSAH 21 required extra coordination with the Scott County Highway Department. Normally, the construction engineering cost for a project is not estimated as there are too many variables which can affect the necessary amount of construction services. These unknowns are what type of contractor is awarded the project and unforeseen changes in the work can vary the amount of construction engineering necessary to complete the project. ALTERNATIVES: RECOMMENDATION: BUDGET IMPACT: ACTION REQUIRED: The amount of construction engineering fees for this project will amount to 14.1% of the overall project cost. This percentage is not excessive when considering the time length of the project and storm sewer changes which require extra engineering services. Another factor is that smaller projects with costs around $100,000.00 or less will have a higher percentage of construction engineering costs than larger projects. The reason is that the several of the construction engineering functions are necessary for a project whether the project is large or small. These fixed costs will give a higher percentage of construction engineering costs to a smaller project. The alternatives are as follows: 1. Approve a motion authorizing additional construction engineering services with TKDA beyond the $12,000.00 maximum limit to $14,354.57 for Duluth Avenue improvements. 2. Table this item for a specific reason. 3. Deny approval of further authorization for a specific reason. The recommendation is to approve number one as the construction costs have not been excessive necessary to complete the project. The project expenditures will be paid from the City's Construction Fund. Municipal State Aid funds will be applied for at the completion of the project and will pay for 8% of the construction engineering costs. The remainder costs will be covered by funds in the Construction Fund. alternative engineering and were Make a motion, as part of the Consent Agen~a, to authorize further construction engineerlng compensation beyond the previous contract maximum limit of $12,000.00 to $14,354.57. ~ " -' " . ;,; ~;.\. :;;'~ ,~;~ .:0 " I~~ . ..., ~ t .' ; . i.
