NZTA drive for better quality surfacing data which is a key element in FWP and modelling. Better monitoring of budgets, allows flexibility to change and drop off sites of a lesser priorityOne point of entry enabling multiple uses as a contractor we are keen to ensure that we get paid for what we do. This approach is reducing duplication of effort and data capture.90% of this setup is standard the remaining but there are contract specific schedule of rates etc and depending on how these are defined requires slightly different levels of management
I'm going to take you on a journey from stockpile sites to the laying of seal through extracting application rates etc from the sealing dockets to its final home in the clients asset register
There are 3 tools in our arsenal that are usedJob management system (JMS) where details of the site and treatment are storedAsset Register – create specific tables for stockpile information (location and material)Reporting Tool which enables data from the above 2 registers to be combined with existing tables to provide progress and completed works data
Stockpile sites are client specific as they are a location based asset. Each site is recorded under its local name enabling the crews to relate to its location. The source options are those valid for the current database contract area. Tired to future proof this by making the psvald and source of the 2nd chip avaiable
These can then be visualised. In this example I wanted to locate all stockpiles with certain mount of grade 3 chip. The ones that fulfilled this requirement are the pick dots, the black triangles represent other sites with lesser amounts of grade 3 chip, thinking process here is that if there are 2 lesser sites together the chip amounts could be combined.
We have been creative with our JMS and have modified the function of some of the lookups. Here the user selects the surf_material code that represents the item ie Rack grade 2 4 ( the chip sizes are stored in the PDA description)
Each site can be entered individually or bulk loaded from a spreadsheet into the Job management system. The external ID is used as a link between multiple systems . From here the detail about the job can be specified and referenced by anyone in the team. This job list has the location and dimension information about the site and the proposed treatment. It can be updated in the office or it can be taken off-line into the field to select treatments and/or confirm or edit measurements. Having the fault as the planned treatment can also be used as a validation check against the actual activity. Offset should be populated from here, as well as width, this will be used in populating back to the RAMM data. This adds flexibility in been able to surface by lane.
Auto estimating allows the estimated costs for each site to be established. Costs include the design reports, and various line marking components if part of the contract. The expected sot for the site is now established. The marking information is not currently used but potentially could cross reference/validate against the information stored in the Asset register
This map shows the grade 3 stockpile sites with sites that will be using grade 3 chip . This allows the planner to locate the closest stockpile for the proposed treatments
When all the work has been done this means that the site can be completed. As part of this process the displacements can be altered and the actual area verified. When sealing and marking are occurring on the same site the work completed date of the surfacing treatment is used as the actual surfacing date rather then the completed date, this also allows us to claim more efficiently where surfacing happens in one month and the marking in the following month. The Client can also see the actual cost of the site.
Other details about the surfacing are also populated here. Again we have reworked existing options to record a number of componets required for the retuning of surfacing data.
Binder, Cutter and Adhesion are structured in such a way to align with existing values in the clients database. For Cutter and adhesion is not just the type but also the Parts Per Hundred. Application Rate and Design life, and stockpile are also selected from the available dropdowns. These values have not been made mandatory as some of these details are not know till the work has been completed.
Further information can be uploaded and stored against each site i.e. spray dockets, photos, extra items such as claims for advertising, this save us time looking for hardcopy at a later date and is also proof for the client if any queries arise. This methodology is also used against the stockpile sites; material testing results can be uploaded, PSV/ALD verification etc.
Customised reporting. This shows the sites and each of the items of work to be carried out, by Client reference, so the cost of each site can be viewed at a glance
This is a progress report (my favourite) for budgeting proposes, expected amount vs actual claimed. Quite often sites are changed as the work as actually takes place keeping a close tabs on the budget means that lesser priority jobs can be postponed as the sealing season progress
The final step to complete the process, entering the data in the clients asset register. Instead of manual entry which can introduce errors, the data can be exported out with aligning columns names and bulk loaded. Delivery of completed c_surface rows can be monthly or at the end of the contract what ever is requested by the client. This data remains as a reference source during the life of the contract. Maintenance Activities can also be retuned for those sites where the treatments such as water blasting occur
