Current Work Experience
01/97–present: Texas Department of Transportation, Austin Texas. Transportation
Engineer. Responsible for collection and analysis of pavement test data, preparing and giving presentations, co-authoring research papers,
troubleshooting equipment problems, evaluating new software and equipment, developing more efficient ways to process data, training new recruits,
directing research projects, managing forensic studies.
Overview of my present job and equipment involved
As part of this job I have co-authored many research papers published by TRB, ASTM and ASCE.
The list of papers is constantly growing by
about two per year. I have also managed several research projects
and inter-agency contracts related to our data collection equipment
and processing software. Our tests include radar, deflection-based
tests, seismic tests, dynamic cone penetrometer tests, crack mappers,
profilers, automated rut measurement, elevation surveys, test grid layout, skid tests and photography.
I do all of these on occasion, but the majority of my work involves the GPR, DCP, profilometer and FWD:
Ground-Penetrating Radar (GPR)
GPR is a technology that allows engineers to see into pavement layers to
measure thicknesses and check for voids, moisture or defects. I am
good at collecting radar data using Pulse and Wavebounce brand
antennas, as well as processing GPR data using analysis software
written by Texas Transportation Institute (TTI) personnel. I can also
run a GSSI SIR-10 system and analyze that data with either the Haescan or Road Doctor software
packages. Though most of my work involves non-contact GPR, I also use
ground-coupled antennas on occasion -- useful for locating rebar,
conduits, pipes, old tanks, etc.
Dynamic Cone Penetrometer (DCP)
The DCP is a tried and true method of developing a profile of soil
bearing capacity with respect to depth. I am proficient in the use of
the DCP (both the manual and automated versions) and can get the California Bearing
Ratio and Modulus by using a spreadsheet and the US Army Corps of Engineers formulas.
Profilometer
Our profilometers use lasers and accelerometers to measure the longitudinal profile of a roadway,
an objective measure of ride quality. I am proficient at collecting and processing this data into the
international roughness index (IRI) and if necessary, the present serviceability index (PSI).
Falling Weight Deflectometer (FWD)
The FWD is a machine that (using a system of hydraulics, weights and
buffers) sends a dynamic load pulse into the ground or pavement.
Geophones then measure the deflection at the load center and other
locations. I am proficient in this machine's use, troubleshooting,
maintenance, and processing the data from it. The set of deflections
allows me, using specialized software, to back-calculate the modulus
of each pavement layer. This ties in well with GPR-determined layer
thicknesses which are an input of FWD analysis.

Helpful Information
I am registered as a Professsional Engineer in Texas (#89205) and New Hampshire (#12013).
Employers may want to try my services on a contract or part-time basis so they can evaluate my work before making any commitment. I have set up a DBA license so I can take individual jobs as needed, and to give potential employers a simple way to evaluate my work. This also allows me to take a wide assortment of jobs as they come.
Compensation does not necessarily have to be in US dollars. I like to barter for other goods and services.
I like to study jobs slowly and carefully before accepting them. I am "slow to promise, quick to deliver." This allows me to honestly claim that I “do everything” and have time for me to brush up on old skills and learn new ones.
My favorite authors are Harry Browne, Ayn Rand, Stefan Molyneux, H.D. Thoreau and Lysander Spooner. I consider their philosophy enlightening and formative.
