I oversaw the build-out of 1,800 SF of office space for the project office.I recognized an opportunity to add a bid item for topsoil to Bell US 190 which will add $1.4 Million to the project profit.I recommended an alternate pavement section using crusher fines in place of lime treated subgrade which eliminate an added cost of lime quantity over-runs, eliminate removal and replacement of sulfate soils to allow for lime treatment, eliminate the risk of sulfate heave, and would save TxDOT and J D Abrams several million dollars.I located utilities and identified several utility conflicts, including a Flint Hills Resources gasoline pipeline, Windstream copper and fiber optic communications, Fiber Light fiber optic communications, AT&T fiber optic communications, and a 30" Atmos natural gas pipeline. I coordinated potholing of the utilities, coordinated relocation of the utilities, and provided information to TxDOT for roadway revisions in the area of utility conflictsI recognized a problem with the construction of embankment slopes and investigated the problem to reveal a significant problem with the GPS earthwork model. The earthwork model was revised, preventing a potentially serious problem with the earthwork and roadway construction.I helped to resolve a conflict between the project embankment and a private roadway so that a portion of the proposed roadway could be constructed out-of-phase to provide access to the private roadway.I was responsible for tracking monthly project quantities, submitting Material-On-Hand reports to TxDOT, creating payforms in Spectrum accounting software to pay subcontractors and material suppliers, and contacting material vendors to order project materials.

I prepared a claim for compensation of Embankment quantity on Kendall IH 10 (Scenic Loop to Balcones Creek). Justification for the claim required a detailed take-off of Embankment quantity, a review of relevant TxDOT specifications and standard drawings, and a review of the way that Embankment quantity has been quantified on TxDOT projects (those with MSE retaining walls) over the past 5 years in the San Antonio District. The claim was successful and resulted in increasing the project revenue by $270,000.For the Granite/AB&R joint venture on the Oak Hill Parkway design/build project in Southwest Austin I estimated the removals, prep ROW, and Water Quality Ponds. Cost estimating for this design/build project required a significant amount of time creating detailed take offs to define the scope of work from a limited amount of information provided by the joint venture's design engineer.For Bastrop SH 21 over the Colorado River I designed and estimated the cost of three sheet pile cofferdams required to install bridge bent footings beneath the river bed of the Colorado River. This required reviewing historic river flood level elevations, performing a risk analysis related to flood water, creating a detailed scope of work for the cofferdam construction, and coordinating with suppliers who could provide sheet pile and strut/waler templates for the coffer dams.For Henderson SH 334 over Cedar Creek Lake I estimated the cost of earthwork, lime treated subgrade, and sheet pile retaining walls (requiring detailed take offs of sheet pile, waler beams, tie backs, and deadman anchors). AB&R was awarded Henderson SH 334, a $41 million project with a double digit profit margin, located southwest of Dallas.For Kendall IH 10 (Scenic Loop to Balcones Creek) I estimated the cost of earthwork, removals, prep ROW, and temporary special shoring. AB&R was awarded Kendall IH 10 (Scenic Loop to Balcones Creek), an $18 million project located between Boerne and San Antonio.

I helped create the proposal and cost estimate for work on the southern section of SH 130 (between Mustang Ridge & Seguin, Texas) when the SH 130 Concession Company invited Austin Bridge & Road to submit a bid for repair of pavement failures which have been occurring along that section of SH 130. Ultimately my proposed alternate pavement section design (with select fill in place of proposed lime treated subgrade) was used for the pavement repairs.For this I spent 15 weeks reviewing potential pavement design solutions. I studied alternate pavement design methodologies, reviewed research related to problems which are occurring on SH 130 (expansive soils, methods of soil stabilization, sulfate soils, sulfate-lime reactions, ground water mitigation). I reviewed original pavement design reports, original as-built drawings, original cross sections. I summarized information contained in project boring logs (soil conditions, soil moisture content, soil plasticity index, sulfate content, results of free swell tests, and ground water observations), created maps of pavement repair areas (including test area locations, boring log locations, ground water observations, and slope conditions), reviewed the inventory of pavement distress types, reviewed the pavement International Roughness Index (IRI) failure history. I also had the opportunity to speak with experts in the field of flexible pavement design and expansive soils. I met with pavement designers, traffic engineers, and geotechnical engineers who could provide alternate pavement designs, shoring designs, and traffic control plans. I found local material sources, contacted earthwork and dewatering subs, created earthwork and material take offs for our cost estimate, and wrote 24 pages of information used in AB&R's proposal (including 'Knowledge of Challenges/Solutions', 'Earthwork & Geotechnical Plan', 'Maintenance of Traffic', and 'Experience on Similar Projects'). It was a very interesting and busy 15 weeks.

As a Senior Estimator, I have been involved in creating cost estimates and bid submissions for various TxDOT, County, City and Design-Build projects. My primary focus has been related to earthwork, materials, temporary retaining walls, and problem solving.On a recent Kendall IH 10 project which was experiencing problems with the construction of temporary MSE walls, I worked to identify specific problems, created solutions for each specific problem, produced detail drawings for each required remedy, worked with Operations to provide a wall monitoring plan, and created a scope-of-work for the geotechnical engineers at Professional Services Inc (PSI) which allowed them to help us by provide a global stability analysis, wall inspection, and recommendations regarding our repair for the temporary MSE wall. Once the wall repairs were completed, TxDOT allowed AB&R to leave the temporary MSE walls in-service, and allowed AB&R to continue with critical path construction work. The approved plan for repair of the Kendall IH 10 temporary MSE walls saved AB&R roughly $500,000 compared to the cost of removal and replacement of the walls.For another recent Bexar IH 10 project, I helped our Vice President of Operations and our estimating group identify an innovative method of temporary shoring using a gravity wall. The shoring was used to support travel lanes on IH 10 east of San Antonio during excavation and replacement of flexible pavement with a very deep section thickness (73" total thickness) in expansive clay soil.

At Odell Geer I worked as the Quality Control Supervisor at Robert Gray Army Airfield / Killeen Joint Use Airport for two heavy earthwork projects (Taxiway "B" and the Terminal Sitework and Utility Project). In addition to the duties of the Quality Control Supervisor, I acted as the Contractor's on-site representative, I handled all of the project submittals, I created weekly project schedules, and met daily with the Owner's Representative from PBS&J.My other responsibilities while working for Odell Geer included managing TxDOT roadway projects Bell FM 2410 (from US 190 to Cedar Knob Road) and Bell US 190 (from Trimmier to FM 195), managing a City of Harker Heights reconstruction of Old Nolanville Road, I designed traffic control plans for a heavily phased City of Taylor project, I managed a building site storm drainage project with Hensel Phleps on Fort Hood, and coordinate an erosion control project and a concrete construction project at various locations on the Fort Hood Tank Trails.

I was pulled into Estimating during a time that saw a lot of growth around Austin and a lot of bidding opportunities for Austin Bridge & Road. I was involved in estimating several successful projects, including the City of Round Rock's Sam Bass Road reconstruction, the City of Austin's Giles Lane reconstruction, TxDOT's Travis IH 35 at Howard Lane bridge widening, and TxDOT's Bexar IH 10 at Foster Road bridge replacement. For the Bexar IH 10 at Foster Road project, I estimated the bridge replacement, the temporary special shoring, and the MSE walls. After award of the Bexar IH 10 project at Foster Road, I created the drawings and structural analysis calculations to submit to TxDOT for the 20' tall steel beam and timber lagging wall that I had designed while estimating the temporary special shoring.

Austin Bergstrom International Airport - North Access Road (now Hotel Drive), McWhirk Road (now Golf Course Road) at SH 71, and Signature Charter's Fixed Base Operator (FBO) Apron.For projects at ABIA, I was responsible for writing Austin Bridge & Road's Quality Control Plan. I created all of our project submittals and all of our weekly schedules. I was AB&R's on-site representative and met weekly with the New Airport Project Team to discuss our schedule, our submittals, and any other items related to the projects. I maintained the project submittal log, and I expedited material deliveries by reviewing all material test results, ensuring that the materials met project specifications so that materials could be delivered prior to submittal approval. I scheduled all material deliveries and improved our project schedules by locating multiple sources of quick lime material (Austin White Lime and Chem Lime), multiple sources or flexible base material (Texas Crushed Stone, Colorado Materials, and Dean Word at Onion Creek), and multiple sources of material haul trucks (Texas Trucking, Aggregate Haulers, Georgetown Transportation, and Odeen Hibbs Trucking). I worked closely with our Quality Control Supervisor to schedule field testing well in advance, avoiding delays related to our Quality Acceptance testing performed by our independent laboratory. I scheduled all subcontractor work on the projects and was responsible for verifying subcontractor quantities of work each month for payment of our sub's. I tracked AB&R's cost and quantities, and submit our monthly pay quantities to the New Airport Project Team.

Stan Schlueter Loop (FM 2410) at Clear Creek Road - In addition to the typical duties of a Project Manager, I designed the false-work deck forms for a parabolic haunch slab bridge over a rail road track at the Clear Creek entrance to Fort Hood, and I worked with a structural engineering firm, Jaster-Quintanilla, to design a temporary retaining wall (steel beam and reinforced shotcrete lagging design) in front of Central Texas College. I purchased both salvaged steel H-pile and new wide flange steel beams for the retaining wall, revised the wall design for available steel sections, supervised and worked along side of the crews that constructed the retaining wall and bridge deck form work.Fort Hood Vehicle Maintenance Facility (Multiple Locations) - As Project Manager for the Vehicle Maintenance Facility project, my responsibilities included attending weekly subcontractor scheduling meetings with the General Contractor (Hensel Phelps) and other subcontractors, coordinating with Hensel Phelps' earthwork sub to schedule our flexible base and hot mix work at various locations throughout Fort Hood, I measured and tracked actual quantities of work performed for monthly billings submitted to Hansel Phelps, and I priced Change Orders for scope changes required to expedite the construction of particular locations.

Created horsepower curves for the operation of reciprocating compressors at compressor stations in Midwestern and Northeastern States. Tested reciprocating compressors to adjust theoretical operating curves for empirical results. Performed vibration acceptance testing of centrifugal natural gas compressors. Operated reciprocating compressors to load reciprocating engines to their rated horsepower for emissions testing at compressor stations located throughout Pennsylvania (Bedford Station, Sommerset Station, Holbrook Station, Middleton Station, Pleasant Hill Station). Performed acceptance testing of turbocharger replacements and pre-combustion chamber retrofits for emissions compliance at Texas Eastern's Pleasant Hill compressor station in Pennsylvania.

As a Field Intern at Maxus, I spent time working with each group involved in natural gas gathering system field operations. Working with Measurement Technicians, I learned how to calibrate orifice flow meters and once a week I would gather paper flow measurement charts at each well-head location and I would replace the paper chart with an unmarked chart. With Field Mechanics I was involved in replacing compressor engine crank shaft bearings and replacing a turbocharger. With Compressor Testing Technicians I helped take heat measurements of gas compressor one-way valves to locate and replace leaking one-way check valves. With Station Operators I learned about compressor engine maintenance (changing oil and filters), operation of station compressors, and operation of pipeline valves. As a Roustabout I helped remove natural gas liquids for the pipeline system by running pipeline scrubbers (pigs) from one compressor station to the next station and spent time painting and maintaining pipeline above ground facilities.
