Platt Thompson Engineering Company, Inc., hereinafter called "Surveyor", agree as follows: I, SERVICES TO BE PERFORMED The Surveyor hereby agrees, at his own expense, to provide all GPS services necessary to properly develop a horizontal and vertical control network encompassing approximately 125 square miles of the City of Corpus Christi meeting accuracy levels stipulated in the Scope of Services section of this agreement. II. SCOPE OF SERVICES A. Scope of Work 1. The Surveyor shall physically construct and establish approximately 14 Type "B" monuments (Exhibit 'A') in existing sidewalks, curbs, headwalls, inlets, or other suitable locations, as specified by the City, by drilling a hole and epoxy grouting -in a survey monument disk provided by the City. 2. The Surveyor shall physically construct and establish approximately 71 Type "A" monuments (Exhibit '8') at or near locations specified by the City. 3. The Surveyor shall prepare a sketch in the field of each monument location, utilizing the City's base drawings giving general and specific distance cies to existing landmarks to aid in the future recovery of the monument. 4. The Surveyor shall, as specified by the City establish horizontal and vertical positions on approximately 85 proposed monuments and occupy up to five existing monuments with known positions for a total of 90 individual sites to be occupied. 5. The Surveyor shall provide a proposed work schedule for City Approval at the beginning of the project, weekly progress reports during the field portion of the work, including sample data, and weekly reports during the calculation phase of the project. 6. The Surveyor shall have a minimum of six (6), two (2) person field crews equipped with Trimble 4000 SST or ST (or compatible) GPS receiver units, each session and a communication package to be utilized throughout this project. GPS Services Contract - 10/05/90 H. Platt Thompson Engineering Page 1 of 8 7. The Surveyor shall schedule all work in accordance with the current satellite constellation to insure a minimum visibility of four (4) satellites, throughout each session. Each session shall consist of a minimum of fifty (50) minutes of satellite observation time. The work schedule shall provide for a minimum of 2, with an average of 2.5, independent occupations on all monument sites, on a network wide basis. 8. The Surveyor shall employ the static data collection method throughout this project. The data obtained by each receiver shall be down -loaded into a suitable computer and configured into separate data files after each day's use to avoid any possible disorder or loss of data, and for ease of accessibility at time when data is analyzed. 9. The Surveyor shall verify the integrity of the raw data and formulate, adopt, and execute a processing strategy. Through this process, numerous independent and redundant single baselines shall be calculated for the various points of the project. 10. The Surveyor shall utilize Trimble's TRIMNET Network Adjustment Software (or equal) and employ the candidate solution vectors, to construct a network. The Surveyor shall utilize the WGS-84 geographic global coordinate system (NAD 83) to obtain a minimally -constrained adjustment, and through an iterative process, the network shall be further refined until a satisfactory adjusted network is established. 11. The Surveyor shall constrain the network by choosing Existing National Geodetic Survey (NGS) monuments within and near the project and holding their published coordinates as fixed network coordinates. Once the "hold" monuments are chosen, a fully -constrained adjustment of the network shall be developed for the NAD 83 datum based on the Texas State Plane Coordinate System, South Zone. 12. The Surveyor shall prepare and submit the National Geodetic Survey Submission Data according to "Input Format and Specifications of the National Geodetic Survey Data Base - Volume 1, Horizontal Control Data, Rockville, MD, January 1989" (blue book) for five of the points as directed by the City Manager or his Designee (City Manager), for inclusion in the national system. 13. The Surveyor shall establish a fully constrained and adjusted network which shall have a minimum precision ratio of closure of 1:100,000 for the horizontal survey data generated, using the NAD 83 Datum. The vertical components of the network shall be established by including vertical data (NGS or others), provided by the City in the data collection and the network, to a precision level of plus or minus three tenths of a foot (0.3'). GPS Services Contract - 10/05/90 H. Platt Thompson Engineering Page 2 of 8 14.

The Surveyor shall provide continuous radio or telephone communication between each receiver unit so that any problems encountered may be dealt with immediately and to optimize the session schedule. 16. The Surveyor shall require the crew chief for each GPS receiver unit, per session, to maintain a log book throughout the duration of this project. The log book shall contain the serial number of each GPS receiver unit used, the station designation occupied by each unit, the time it was turned on and off, and the height of the unit above ground along with any pertinent information regarding the weather conditions at and the physical environment around each observed station, and the name of the crew chief in charge. 17. The Surveyor shall provide the necessary project management and coordination of the services to perform the work, as set out herein. 18. The Surveyor shall be responsible for providing material, transportation and the construction of an observation tower for utilization on one to four points as directed by City Surveyor or his Designee (City Surveyor). 19.
