DDC | WATCH: Why is DIM software the future of drainage surveys?
DDC Engineering Solutions have created DIM, a unique specialist solution which enables a comprehensive digital drainage modelling and provides a smart live data sharing and management system.
The innovation of DIM is defined by its extraordinary features as it is fully compatible with HADDMS, simple to operate, stable, and supports real-time data transfer and viewing between field devices and between field device and office.
Furthermore, it supports and displays all type of drainage features which allow the drainage network to be mapped out on site.
The software was developed to allow validation surveys and infill gaps in the highways drainage network for Highways England. It has been beta tested and successfully implemented onto various highways and IRIS projects and has proven to give the asset engineers the confidence of 100% data accuracy.
Carol Lewis-Han, the Technical Director of DDC explains the reason behind DIM:
“Our in- depth research showed that current software is incapable of meeting the criteria required to undertake a beneficial survey that meets HE’s remit. Limiting factors of previous software renders its functionality unsuited to drainage surveying.
“This has led to unnecessary spending and poor value for money. DDC designed DIM to facilitate an easier drainage asset modelling process and to generate a reliable drainage flow model for HE.”
A case study performed by DDC engineering indicated that the ‘green’ benefit result is significant.
The case study performed a comparison between capturing drainage asset data in the traditional method and with the new software and RTX technology on a typical drainage asset inventory validation and gap filling survey job.
To undertake a 16km drainage asset survey in the traditional method, an approximate 10 to 15 pages of A1 size drawings will be printed for GPS operatives to take on site. Use of the newly developed software meant this job was paper free on site.
In addition to the environmental benefit, the company also reduces its costs as there are also savings in ink and electricity. Paper use was reduced by 70% and electricity by 55%. By using the new software, the operatives can see clearly where the target drainage assets are, and the software can even direct the operatives to the target assets.
This increases worker efficiency as with the existing data that was preloaded onto the equipment, the operative only needs to click into each existing asset in the equipment and validate the attributes. DDC’s GPS operative in such cases achieved over 2000 meters of road drainage survey per shift, where only 1120 meters previously.
The resulting 16km scheme took 8 shifts with the new software instead of 15 shifts, which reduced the footprint on site by nearly 50%. This reduced the fuel used whilst out on site, CO2 levels and emissions for the environment, and the traffic management needed was reduced by nearly 50%.
Being an innovative leader of highways drainage surveys, DDC has now developed groundbreaking software for drainage surveys.
HE has, over the past 10 years, commissioned thousands of highways drainage surveys throughout England.
The information is stored in the national database – HE DDMS. Surveys have been undertaken as many as 6 times on the same stretches of carriageway due to the data being inconsistent.
This has led to unnecessary spending and poor value for money. To reduce unnecessary spending, HE is reviewing these datasets.
The first review is to cleanse the data. HE undertakes a consolidation exercise of the data, to remove the duplicate surveys, leaving a ‘baseline’ of drainage data. Once consolidation has been completed, the next stage is to validate the data to ensure that the ‘baseline drainage model’ is a true visual of the network.
Survey teams will be required to visit the sites to validate the model and infill gaps if no survey data exists.To validate the data and infill gaps, DDC undertook market research and consulted industry professionals on the functionality of current software.
The conclusion was current software is incapable of meeting the criteria required to undertake a beneficial survey that meets HE’s remit. Limiting factors of current software renders its functionality unsuited to drainage surveying.
The inability to update and amend preloaded existing data, renders the software ineffective.
Current software does not display linear and region features. This is restrictive and inhibits the production of a drainage flow model in real time.
Post processing is very time consuming and involves reviewing asset sketches and asset photos to build a drainage flow model. This process is not only time consuming but also contributes to inaccuracies in survey output. The developed software has the intelligence to produce a network flow model in real time. The new software supports and displays all type of drainage features.
The software is fully aligned with HE’s objectives and it efficiently produces drainage information management. The real-time information sharing and live viewing of the drainage flow model will help Highways Maintenance teams quickly identify network issues and high flooding risk areas.
Corrective action to be taken swiftly to avert disruptive repairs.
The importance of the software is its ability to create and supply real-time intelligent drainage analysis information that can be shared live with multiple users.
