QA/QC Engineer, City of Oklahoma City Wastewater Master Plan, Oklahoma City, Oklahoma. Dr. Habibian provided QA/QC of the master planning project for OKC. The project involved flow and rainfall monitoring and hydraulic modeling of four basins. The modeling software InfoWorks was used for this project. The Master Plan identified approximately $400M of improvements to the collection system.
Project Manager, City of Tulsa Upper Mingo Creek SSES, Tulsa, Oklahoma. Dr. Habibian managed an evaluation of about 330 miles of sewer lines. The evaluation included visual inspection of manholes, CCTV of sewer lines, smoke and dye testing, flow and rainfall monitoring, hydraulic modeling, and an implementation plan. The study recommended about $18M of manhole and line rehabilitation and $10M of new lines for capacity enhancement.
Technical Specialist, Condition Assessment of Main and Branch Interceptors and Outfalls, Passaic Valley Sewage Commission, Newark, New Jersey. Dr. Habibian provides technical direction for condition assessment of approximately 40 miles of main and branch interceptors and associated manholes, inverted siphons, outfalls, venture meters, and regulator chambers. The project also includes development of design contract and construction supervision of cleaning contract, emergency repair contracts, and rehabilitation contracts.
Technical Specialist, City of Bozeman Sewer Pipe and Manhole Rehabilitation Design, Bozeman, Montana. Dr. Habibian performed condition assessment and evaluation of sewer pipes and manholes in the downtown area of the City of Bozeman and developed rehabilitation recommendations.
Technical Specialist, Metropolitan Sewer District River Des Peres Foul Water Interceptor Evaluation and Rehabilitation, St. Louis, Missouri. Dr. Habibian evaluated the condition of approximately 25,000 feet of 84‐ inch through 96‐inch interceptor, and developed recommendations for eliminating the I/I sources. While the interceptor had been initially thought to need full rehabilitation, the evaluation indicated rehabilitation of leaking joints and manholes would address the I/I problem. MSD was able to save several million dollars by not needing to rehabilitate the full length of the interceptor.
Project Advisor, Unlined RCP Sewer Evaluation & Rehabilitation Program, Las Vegas, Nevada. Dr. Habibian provided guidance on performing CCTV inspection of about 90,000 feet of sewer interceptors, condition assessment and developing appropriate rehabilitation recommendations.
Technical Specialist, City of Salt Lake, Utah Large Diameter Pipe Inspection and Orange Street Interceptor Rehabilitation, Salt Lake City, Utah. For this project, Dr. Habibian was involved with the selection of the best inspection methods using CCTV, laser scanning and sonar profiling to conduct an inspection on 24,000 feet of, 42‐inch and 48‐inch RCP for the Orange Street Interceptor. The project also included design of the rehabilitation for three alternatives, slip lining, cured in place pipe and spiral pipe repair (SPR) for the sewer pipe to meet the restrictions of high ground water, residential settings and a nearby golf course. Work also included assistance during construction.
Technical Specialist, Trinity River Authority Ten‐Mile Creek Interceptor Evaluation, Arlington, Texas. Dr. Habibian evaluated the condition of approximately 20,000 feet of an 18‐inch interceptor through CCTV inspection and identified deficient sections for rehabilitation.
Technical Advisor, TRA CRWS Interceptor Evaluation, Dallas, Texas. Dr. Habibian developed an evaluation scoring process for TRA’s Central Region Interceptor System and developed rehabilitation recommendations including planning level costs.
Technical Specialist, County Sanitation District 1 Project 4 North Sewer Rehabilitation, Sacramento, California. Dr. Habibian evaluated condition of sewer lines for Project 4 North and developed rehabilitation recommendations. Developed specification, design details, and cost estimates for rehabilitation. CIPP, Pipe bursting and the Tenbusch method were specified for rehabilitation.
Technical Specialist, Orange County Sanitation District Failure Investigation and Repair of 36‐inch Fiberglass Force Main, Orange County, California. Dr. Habibian investigated the causes of failure of a 36‐inch fiberglass force main. The investigation included review of construction documents and inspection reports, CCTV inspection of the line, and detailed structural calculations. The repair phase included the development of specifications for the repair, participating in meetings with repair contractors, and review of contractor’s submittals. Additionally, technical assistance was provided to the owner to respond to Contractor’s claims.
Technical Specialist, Orange County Sanitation District OOBS Force Main Condition Assessment and Rehabilitation, Orange County, California. Dr. Habibian evaluated the condition of a 120‐inch steel force main using several inspection tools including CCTV, laser profiling, electromagnetic, and ultrasonic testing. Areas of concerns were identified and recommendations were developed to address deficiencies. Carbon fiber repair was selected for rehabilitating the corroded section of force main. Technical specifications were developed and design calculations were performed for the carbon fiber solution. Construction phase services were also provided.
Technical Specialist, San Jose – Santa Clara Regional Wastewater Facility Risk‐Based Condition Assessment Plan, San Jose, California. Dr. Habibian oversaw the development of a Risk Analysis Framework to define and evaluate the various mechanisms influencing the yard piping risk of failure. A GIS‐based Asset Prioritization Tool (APT) was developed to automate the risk analysis process and manage the individual scoring and weighting factors for each risk factor/category, perform the risk analysis calculations, and deliver results back to the RWF in a GIS‐based user interface. Additionally, a Condition Assessment Protocol was developed to provide the RWF with guidelines on data collection criteria, inspection technology selection, timeframe for condition assessments, residual life estimates, and preparations for condition assessments.
