Participates in a training program requiring 180 Technician Development Hours. Performs related duties as required.

Pay Grade: 11

• Conducts standard sampling and field‑testing materials, including density test by application of the standard method of Portland Cement Concrete, Bituminous mixtures, aggregates, quarries, and pits.
• Conducts standard construction surveying, including instrument duties, provision of adequate staking to permit construction, identification and staking of right‑of‑way, reducing and checking field book notes of standard surveys, and determining, plotting, and checking standard cross sections.
• Enforces traffic controls established during construction.
• Computes and records areas, volumes, and cost estimates.
• Determines drainage areas from survey data of topographic maps.
• Determines and utilizes Federal, State, and AASHTO load and clearance factors applicable to pavements and structures.
• Performs calculation of safe speeds on horizontal curves and determines super‑elevation, and calculation of sight distances on vertical curves and screened horizontal curves.
• Prepares and checks detailed estimates, bills of materials, and cost estimates.
• Reviews and checks location and property surveys.
• Posts as‑built features on design plans of a project.
• Reviews test results to determine if they provide a reasonably unbiased estimate of the information desired.
• Reads topographic and hydrographic maps, charts, plots, and drafts topographic information.
• Performs minor adjustments to simple optical instruments (adjust level, etc.).
• Performs triangulation and traverse surveys to meet 3rd order precision standards; operates levels of 3rd order precision in bench level runs and cross‑sectioning – including balancing of back sights and foresights.
• Directs survey helpers on location surveys.
• Reviews and evaluates routine technical traffic control studies, including simple signalization requests, systems to signs and pavement markings, hazard elimination projects, and studies to determine conformance to established standards.
• Validates and compiles traffic volume data to assist engineers or specialists in determining traffic trends.
• Travel may be required; therefore, a valid driver’s license is required.

• Knowledge of first aid procedures.
• Knowledge of individual responsibilities under OSHA and other safety requirements.
• Knowledge of the applications of computers to design and estimate.
• Knowledge of the fundamentals of photogrammetry as applied to design.
• Knowledge of care, cleaning, basic calibration, and safeguarding of standard laboratory and field equipment and instruments.
• Knowledge of basic surveying and drafting is required to plot sample locations accurately.
• Knowledge of materials testing terms, symbols, punctuation, grammar, spelling, and sentence structure.
• Knowledge of basic principles of physical science.
• Knowledge of methods for collecting and storing samples for future testing; knowledge of aggregate sampling.
• Knowledge of reagents used for standard field and laboratory tests.
• Knowledge of requirements of special programs such as EEO, OJT, Davis‑Bacon, and Workers' Compensation.
• Knowledge of traffic safety requirements at and around work sites.
• Knowledge of the utilization of vertical aerial photos and the basic concepts of photography.
• Knowledge of traffic safety requirements during construction and of methods to safely maintain or re‑route traffic.
• Knowledge of procedures required to coordinate work with utility companies and government agencies, with emphasis on electrical device layout and installation.

• Ability to perform and interpret construction surveys as related to the…
