PMS is a critical tool used by agencies to plan and budget the maintenance of their most valuable asset, the network of roads. We partner with cities to help to develop their own pavement management program (PMP), update the inventory and strategize their approach to not only maintain their asset but also to improve it for better quality or life of their residents.
To fulfill this task we utilize our team of pavement engineers, GIS experts, and certified inspectors, who are highly trained in collecting the network data and updating PMP and GIS data basis, and developing strategic plans. Our in-house pavement engineer is expert in developing life cycle models for different type of pavements with different application to accurately estimate their remaining life. This information eventually will help our Pavement Management team to come up with the most cost effective and practical maintenance and rehabilitation plant to address the needs of the agency in coming years.
Twining’s team are well versed on different PMS software (i.e. Micropaver and Streetsaver). They can update your existing software with the latest version or transfer your existing database from one to another, depending on your needs.
Our Pavement Management team initially will set up a meeting to review the objectives and deliverables with the City. We will also collect all available data maps to import them into our database. Depending on the condition of the data, our GIS team will develop/update the GIS map of the agency’s network. The map then will be transferred to our PMS software for further analysis. Based on the developed/updated map, our PMS team will produce the list of available sections and samples within the network. Then random samples will be selected for further data collection in the field.
Our data collection team goes through a rigorous training every your to assure the quality of their work and also to minimize the variability of their data. Moreover, at the beginning of each project, our team will calibrate their data collection method by collecting data on a preselected test strip (three different samples within the project) individually and comparing the results. This will help us to improve the accuracy of our data throughout the project. Our team collects the field data in accordance with the latest ASTM Standard D 6433 using tablets. This will significantly reduce the time of data entry and also prevent any possible error.
The collected data will be transferred to the office. Our engineers in the office will run statistical analysis on the collected data to assure its quality. Then the data will be transferred to PMS software and all network analysis will be performed there.
After the initial analysis, we will generate a draft report. We will present our initial findings and plans to the City. The outcome of our meeting will be transferred to the software. Any additional sections, or samples will be created and the associated data will be collected.
Based on all our findings in the field and discussion with the agency, we will develop a final report which incorporates the details of the existing condition of the network, per section. Also, we will develop all the maintenance and rehabilitation options for the agency based on different scenarios. Our typical scenarios are the following:
Estimated Pavement Condition Index with no budget (in 5 years)
Estimated Pavement Condition Index with a constant budget (in 5 years)
Estimated required budget to achieve a certain PCI (in 5 years)
In addition to the above mentioned reports, we can develop other reports per the request of the agency.
At the end, our team will present the final findings to the city and will deliver the hard copy and soft copy of the report to the agency. A copy of the updated software and database will also delivered to the agency. Depending on the need of the agency, Twining’s team can provide training sessions for the personnel of the agency as well.
