TranSystems,Inc. 500 West 7`b Street Suite 600 Fort Worth,Texas 76102 RE: Subsurface Utility Engineering Bonnie Drive,Sarita Drive,Merida,Waverly Park Addition Fort Worth,Texas Dear Mr.Hobbs: Gorrondona and Associates, Inc. (GA), is pleased to submit a cost proposal for Subsurface Utility Engineering (SUE) required for the above referenced project. This proposal is based on information obtained during our meeting and information received on November 5, 2008. Introduction GA will perform the SUE work required for this project in general accordance with the recommended practices and procedures described in ASCE Publication CUASCE 38-02 (Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data). As described in the mentioned ASCE publication, four levels have been established to describe the quality of utility location and attribute information used on plans. The four quality levels are as follows: • Quality Level D(QL"D")—Information derived from existing records; • Quality Level C (QL"C") - QL"D" information supplemented with information obtained by surveying visible above-ground utility features such as valves, hydrants,. meters, manhole covers,etc. • Quality Level B (QL"B") — Two-dimensional (x,y) information obtained through the application and interpretation of non-destructive surface geophysical methods. Also known as "designating" this quality level provides the approximate horizontal position of subsurface utilities within approximately one foot. • Quality Level A(QL"A")—Also known as"locating",this quality level provides precise three dimensional (x,y,z) information at critical locations by exposing specific utilities. Non- destructive vacuum excavation equipment is used to expose the utilities at specific points which are then tied down by survey. It is the responsibility of the SUE provider to perform due-diligence with regard to records research (QL"D")and acquisition of available utility records. The due-diligence provided for this project will consist of reviewing the "As-Built" documents previously compiled by others. Utilities that are not identified through these efforts will be here forth referred to as "unknown" utilities. GA personnel will scan the defined work area using electronic prospecting equipment and Ground Penetrating Radar 6707&entwood Stair Road•Suite 60 4 Fort Worth,'texas 7E1 12 P 8t7.496.1;?4-a=ax 817.416.17634 Q Mr. Mic mel Hobb,,P.E. January 5.2009 Pige243 (GPR) to search for"unknown" utilities. However, GA is not responsible for designating or locating these"unknown"utilities. Scope of Work Based on information provided by TranSystems, GA has developed a preliminary scope for the SUE work required for this project. The scope of work may be modified, with TranSystems concurrence, during the performance of the SUE fieldwork if warranted by actual field findings. The scope of this proposal includes Quality Level "B"SUE services for three projects; along Sarita for 3,100 linear feet; Waverly Park Addition for 1,200 linear feet from Brandon Lane to the outfall by US 80; and along Kermit Avenue from 80 feet west of Bonnie Drive centerline 450 linear feet. GA will designate all known utilities from ROW to ROW within the limits previously defined. The scope along Fuller Avenue from Sandage Avenue to Lubbock Avenue and along Boyce from Merida Avenue to just west of Lubbock Avenue; in addition, the utilities within the utility corridor between Merida Avenue and Lubbock from Fuller to Boyce Avenue will also be designated. GA will designate,QL"B"all known utilities from ROW to ROW within the limits previously defined. All required surveying for this project will be completed by others. An electronic copy will be delivered to GA for review. Desienatine Procedures Prior to beginning field designating activities, GA's field manager will review the project scope of work and available utility records. Once these initial reviews are complete, the field manager and technicians will begin designating the approximate horizontal position of known subsurface utilities within the specified project limits. A suite of geophysical equipment (electromagnetic induction, magnetic) will be used to designate metallic/conductive utilities (e.g. steel pipe, electrical cable, telephone cable). Non-metallic/non-conductive utilities will be designated using other proven methods, such as rodding, and probing. Where access is available, a sonde will be inserted into the utility line (e.g. PVC gravity sewer pipe) to provide a medium for signal transmission, which can then be designated using geophysical equipment. Accurate collection and recording of designated utilities is a critical component of the SUE process. GA has developed a proven method of collecting and recording survey information once the utilities have been designated in the field. GA's field manager will produce detailed sketches depicting each utility as well as relevant surface features such as roadways,buildings, manholes, fire hydrants,utility pedestals, valves, meters, etc. Each utility will be labeled with a unique ID code. For example, if two buried electric cables exist on the project, one will be labeled El and the other E2. Paint and pin flags will be used to designate the utilities in the field. A labeled pin flag or paint mark will be used to mark each location where a survey shot is required. Shot points will typically be placed at 100-foot intervals on utilities running parallel to the alignment and at 50-foot intervals on utility crossings. The locations will be numbered sequentially for each individual utility line. For example, if there are 50 shots required on buried electric line El, the points will be numbered El-1 through E1-50. Preliminary field sketches depicting the designated utilities will be prepared for use during subsequent surveying activities. These sketches will also be used to check the survey information for completeness and accuracy. Mr. Michael Hobbs, P.E. JanuarN 5.2009 Page 3 of 3 Deliverables GA will produce a SUE file depicting the type and horizontal location of the designated utilities. Where no test-holes have been completed, the size and material type will be provided, only if the information is indicated on available record drawings. TranSystems will provide GA with base map/topographic files in Microstation V8 or AutoCad format for use in preparing the SUE file. GA will utilize it's standard utility line styles and symbology to produce the utility file. Schedule Records review can commence upon receipt of a formal notice to proceed (NTP) from the TranSystems. Designating field work can commence within 2 days after receipt of NTP. GA estimates that the designating phase of work can be completed in eight(8)workdays. Estimated Fees GA proposes to perform the work on a unit price basis for each project as follows; Sarita Drive—3,100 linear feet at$2.50 per foot=$7,750.00 Waverly Park - 1,200 linear feet at$2.50 per foot=$3,000.00 Bonnie Drive—450 linear feet at$2.50 per foot=$1,125.00 Fuller&Boyce Avenue— 1,450 linear feet at$4.50 per foot=$6,525.00 Survey costs for the above projects is$4,250.00 The total cost for QUB"and its applicable survey is twenty-two thousand,six hundred fifty dollars and 00/100 cents($22,650.00). We look forward to working with you on this very important project. If you have any questions or require additional information, please contact me.
