Craig A. Smith & Associates Engineers ● Surveyors ● Subsurface Utility Engineering ● 3D Subsurface Imaging ● Utility Coordination capabilities was utilized to collect data in the horizontal and vertical planes. A total of approximately 75 aerial targets (control points) were set allowing for QA/QC reference and orientation to accomplish a targeted accuracy of 0.1 to 0.2 feet (+/-), both horizontally and vertically. The control points were relative to the North American Datum of 1983 (NAD 83) with the 2011 adjustment, horizontally, and the North American Vertical Datum of 1988 (NAVD 88), vertically. Collected survey data was processed and sent to CAS CADD Department for further processing through CAS Survey’s 3D software and including to the over all basemap. City of Dania Beach SE 2nd Avenue and SE 7th Street Water Main Replacement – City of Dania Beach, Florida. Mr. Keener Served as Principal Surveyor for the construction of the water main replacement project The scope for the project included computation base sheets which encompassed computing overall site geometry for purposes of providing surveying control and for determining final locations of water main improvements. Services also included staking alignment at 50 foot intervals where CAS provided nail and tin tab / hub and tack at a ten (10) foot offsets to the proposed water main at approximate 50-foot intervals; Staking and grading of hydrants where CAS provided lath at centerline and set two graded offset laths. Services also included staking locations of valves, tees and plugs and as-built record survey of water system where CAS provided drawings indicating measured data of the constructed water system. All fittings, conflicts, vertical deflections, etc. were shown based on CAS field measurements showing measure downs, pipe separations, and pipe cover. Mr. Keener performed quality control and quality assurance for the project. City of Ft. Lauderdale Water Distribution System Mapping Update– City of Ft. Lauderdale, Florida. Mr. Keener Served as Principal Surveyor and oversaw the surveying and subsurface utility engineering for the water utility system mapping updates delineated within the CA Smith Zone located within the City’s northeast service area. The project area contained approximately 168,960 linear feet or 32 miles of existing 8” water pipelines. The scope of work included 2D ground penetrating radar of the existing water mains within the prescribed right-of-way corridor including identify/verifying location of existing isolation valves, air-release valves, fire hydrants, etc. and approximately 12,000 associated water meters. Survey physically located the utility surface marks for existing water mains provided by the CAS Utility Locates Department and above ground valves, fire hydrants, air release valves, etc. relative to the defined scope. Missing and/or unknown pipes based on the GIS data supplied by the client was mapped as applicable. City of Lake Worth Beach, Lake Osborne Estates Water Main Replacement Project – Phase I, City of Lake Worth Beach, Florida. Mr. Keener Served as Principal Surveyor for the engineering design of the Phase 1 improvements which included the installation of 16,400 linear feet of new 6” to 8” PVC water main serving 228 homes in the Lake Osborne Estate residential area. The new water main replaced existing asbestos cement pipe (ACP) and also improved fire protection and pressures to the neighborhood residences. Work also included the abandonment of existing ACP water mains and the relocation of meters and services from the rear of the residential lots to the front of the lots. Two (2) 40-foot 8-inch HDPE horizontal directional drills were performed under High Ridge Road, which was newly paved, to avoid pavement impacts during installation. A map of specific survey was prepared for engineering design which included physically locating all above ground visible improvements and buried utilities within the existing right-of-way. More than twenty (20) utility test holes were performed at pertinent locations to verify buried utilities and potential conflicts. Information from Test Hole reports was incorporated into the survey base maps. Rims, pipe inverts, size, and material information were shown at all drainage structures. A baseline was established and cross sections taken at every 100 feet. All elevations were shown relative to the North American Vertical Datum of 1988. Trees 3” or greater in diameter within the corridor were located and shown by common name with caliper size at average breast height. In addition, all existing water meter locations were surveyed and shown. City of Ft. Lauderdale, Design-Build Force Main By-Pass Line Installation – City of Ft. Lauderdale, Florida. Mr. Keener Served as Principal Surveyor and oversaw the surveying and subsurface utility engineering (SUE) within an approximate 3.2-mile corridor for the design-build installation of a force main bypass line. The corridor included SE 10th Ave. from SE 18th St. to SE 12th St.; SE 9th St. from SE 12th St. to SE 2nd Ct.; SE 2nd Ct. from SE 9th St to SE 10th St. and across the Himmarshee Canal; NE 11th Ave.; and NE 6th St. east to NE 15th St. and north to Sunrise Blvd. A specific purpose survey was conducted within the right-of-way identifying all above grade utilities and 52
