2. H&B General Information • Land Surveying Support Services • Locally Based Office (Manchester) • WBE/DBE and ESB Certified • City of Richmond Project Experience • (58 projects to date) • Richmond WWTP • Richmond CSO No. 0004 Project at Gillies Creek • Multiple Stream Restoration and Drainage Improvement Projects • Multiple Sewer Improvement Projects • Multiple Intersection Improvement Projects • Cannon Creek Trail - Phase I, II and III

3. H&B Key Personnel • Alison W. Hanson, L.S. and • Leslie R. “Les” Byrnside, L.S. • The Management and personnel at H&B have extensive experience in all phases of land surveying & aerial photogrammetry. • 75 years plus of combined experience • Streets and Highway projects • Water and Sewer line projects • Stream Restoration and Drainage Improvement Projects • Boundary and Topographic Design Surveys • Projects are collected and processed using a “Field to Finish” approach. • Field survey technicians work as cad operators in the field • Streamlined office compilation process • Four fully equipped survey field crews and the necessary office staff and technology are available. • Quick responsiveness on all surveying requests • Prompt preparation of the final product

4. H&B Project Example • Willow Oaks Stream Restoration and Drainage Improvements. Survey data provided assisted the engineer and the city in analyzing existing storm water conditions. In total, H & B surveyed 8,500 linear feet of drainage corridor having an approximate mapping width of seventy five feet. The location consisted of the existing roadways, drainage systems, planimetric physical features such as water valves, fire hydrants, electric and communication hand holes and junction boxes as well as underground utilities that were marked by others. The final product for this project was a survey performed to City of Richmond Standards. The finished mapping scale for portions of the project was at a 1” = 20’ horizontal scale with 1’ contours and the remaining portions of the project was mapped at 1” = 30’ with 1’ contours.

5. H&B Project Example • Richmond Wastewater Treatment Plant This project was a fast track project. It consisted of an elevation survey and an as-built survey of the weir system in the final sedimentation tanks. Data was collected using conventional leveling methods while adhering to plant safety requirements. This survey was based on and tied to datum relative to project control points provided by the plant and engineer. We located and recorded the elevations of the top of the outermost tooth of the plates at either end of the weir ports for each bay. (Approximately 576 points) .We also located and recorded the elevations at each end of the troughs. (Approximately 192 points). The final product for this project was an elevation survey. This data was then provided in a excel spreadsheet showing the vertical information of the locations stated above per tank. Our Vertical Tolerance was 0.01’.

6. H&B Project Example • Hospital Street Waterline Improvements This project consisted of surveying points along the proposed Hospital Street waterline improvement project. This survey was used so that five (5) critical intersection crossings could be maneuvered due to the high volume of underground utilities. This project included full courthouse research for property platting, GPS surveying for project control and a full topographic survey using a conventional “Carlson” field to finish survey approach showing detailed terrain and underground utilities as painted by Miss Utility. The location consisted of the existing roadways, drainage systems, planimetric physical features such as water valves, fire hydrants, electric and communication hand holes and junction boxes as well as underground utilities that were marked by Miss Utility.
