Schriekel, Rollins and Associates, Inc. 1161 Corporate Drive West Suite 200 Arlington, Texas 76006 June 10, 2002 RE: Creekview Drive Project #ST00-01 Dear Mr. Hartman: The letter is written as a follow-up to our meeting in the field on Thursday, June 6, 2002 to discuss the sidewalk construction along Creekview Drive. During the course of our conversation, we again discussed the confusion of in-the-field surveying along this route prior to the design of the project. The project assigns $25,600 (roughly 16% of the design cost) for topographic and right-of-way surveying. Of that amount, $18,100 is assigned to the Creekview portion of the project and the remaining $7,500 is assigned to the Freeport Parkway portion of the project. There is a note that states that the areas have already been flown but not mapped and need special details in the creek area. It was my understanding in reading the basic services on the schematic design that there would be an in- the-field survey. Page I 0, paragraph 5 of the contract under schematic design states "the engineer shall provide necessary design field surveys for his use in the preparation of the plans and specifications". The only time I am aware of a design taking place without a detailed in-the-field survey is when you are basically rebuilding existing infrastructure. In the case of cutting a road through pasture land, it is my opinion that even if there was aerial contouring provided that there would be spot elevation checks in the field to verify the accuracy of the information. As I am sure you are aware, aerial topography is not always accurate. The lack of an on the ground survey has created confusion because there are conditions in the field entirely different than what was shown on the plans put out to bid. At this point, we are awaiting information from your firm concerning the additional dirt to be removed, any additional walls to be constructed and any change in the scope of the project to construct the sidewalk on the north side of Creekview. If there is an increase in cost to the City above the pricing reflected in the bid, then there may need to be additional discussions to determine whose financial responsibility the increase in cost will be. One item that would be helpful is a detailed accounting of the expenditures of the $25,600 for the topographic and right-of-way survey. The invoices submitted to the City for payment have not been broken down adequately enough to determine the amount of hours for each task. It is my hope that the construction of the sidewalk can be accomplished within the limits of the original contract. Sincerely,en~ne~t~/x' ~ K h M. Griffin, P.E.
