I I I I I I ':ENGINEERING By: Backgroundi CASE SERVICES FOR WOOD POND PROJECTS Steven Jankowski, City Engineer On August 27~ 1991, the City awarded engineering work for Wood Pond Projects to Hakanson Anderson ASsdcia~s. The work encompassed extending a deep sanitary interceptor sewer adjacent to wetland ~r ~e g~neral project area and the installation of sanitary sewer, watermain, storm sewer and street imp~ove4nents within the four subdivisions. The construction took place under three separate ¢ontra~ts v~ith a total construction cost of approximately $1.4 million. In requesting ~gi~eering proposals for these projects, the City requested a not-to-exceed price for basic engineering 4ervices and an hourly rate along with an estimate of the total cost required for technical coasgrue~on services. The basis of award was made upon the not-to-exceed price for basic engineering sgrvices, as it is recognized that the technical construction services required can vary with the Contractor, the weather and other factors which are difficult to estimate. As this project is dra~vinl~ to a close, the invoices from Hakanson Anderson Associates for basic engineering se vi~s is at 99% of the $54,775 not-to-exceed price submitted in their proposal. The invoices for:h )uriy services has exceeded the estimated cost of $81,650 by $13,897 with the project 99% ~,.o replete. The City's COn a'ael[ual agreement with the engineer calls for payment for the number of hours deal., pin these hourly services and is not limited by the estimate. actually e~:e] roviding Nonetheless,'t~ ar~ount by which the actual hours exceeded the estimate are significant and I have requested: an e:;pl~ation by the engineer. A letter from the engineer in response to this request is enclosed. In' r~vie4ving this letter, the excess cost is attributable solely to staking. Actually, the inspection servtees We slightly below the number of hours estimated. I believe ~e n~tti~e contained in Mr. Raatikka's letter describes the various elements which were responsible f0f[.the ~ditional work and consequently the additional cost, and I will have an exhibit at the meeting I~o ill0strate the specific areas which are generally referenced in the letter. Recommendation: The agreemen~witlj the engineer specified compensation for these particular services on an hourly basis and I b¢l,!.evelthe hours submitted for billing are accurate and reasonable for the amount of service actua!l~t rendered. I therefore recommend payment of $18,878.45 in invoices which were removed from ~the:lune 23, 1992 City Council meeting invoices for Improvement Projects 4~'91-13 and 4~91-14. sr Council ActiOn: Motion to app~°ve ipayment of invoices to Hakanson Anderson Associates for services rendered for Improvern~t ~ojects ~91-13 and ~91-14 in the amount of $18,878.45.
