Developed to include an array of useful features specifically for road and railway engineering surveyors.
Covers the entry, editing of strings and related data such as construction and dips. Strings are taken as horizontal and vertical alignments with widths and crossfalls attached to make up the road profile. Strings are displayed using plan views, long sections and cross sections so that the string can be seen and checked by eye as it is entered
Construction details are applied by specifying the depth of construction and the shape of the edge. A library of these edge details is supplied, this can be extended and customised as necessary. Edge details can also contain standard information about kerbs and construction widths, saving unnecessary data entry. Pavements and channels are also supported.
Dips are specified by giving a series of offsets and a dip at each offset. Dips may be entered for any chainages, and the system interpolates intelligently between them.
Once a geometry has been defined a long section of the terrain is displayed where you can add the vertical geometry and have the software display cut and fill areas for the long section of the route. Move IP’s graphically with the areas being updated to balance cut fills
Enter rules for carriageway and verge construction and let the Road and Rail Design Module develop the complete model.
The Calculate volumes function from the design window gives you the opportunity to fine tune the design to give the most cost effective route.
Now you only need to enter the gauge, horizontal, vertical alignment, cants and the position of the vertical alignment. The alignments can be entered by hand or imported from from MX or Intergraph (now Bentley). Cants can also be entered by hand or imported from a model. Once an alignment has been entered it is possible to determine lists of coordinates for either rail, centre lines or any offset in both plan and elevation. Alternatively points on the track can be surveyed and their relationship to the design calculated, i.e. giving lifts and slews to the design.
These lifts and slews can be exported to various formats including a ‘WinAlc’ used by Plasser tamping machines. Checking as built rails using the ‘versine’ method is automated using the software. The rails are surveyed and those points selected. A table can then be formatted in the usual way to show the chord length surveyed between each point, the surveyed gauge, the actual and theoretical versine offset.
As an Nrg Survey software user for over twenty five years I have found Nrg to be the best all round package for volumes road setting out and topographic surveys. Technical support is second to none. If it doesn’t do it, make a suggestion and if it isn’t there somewhere it usually gets added to the next release
NRG Survey have been very attentive in attending additional rail based features added to their core software. Their professionalism and customer satisfaction needs are second to none.
C.O. Williams Construction Limited are a heavy civil engineering contractor based in Barbados in the Caribbean, currently employing 260 staff. Our contracts include road building, landfill cell construction, coastal defence works, marine works, airport runway and taxiway construction and resurfacing, property development subdivisions, golf course construction, substructure and external works, and the like.
We have been using NRG Survey System and Digital Terrain Mapping software since 1998 and they have become an essential part of our workflow. The software is employed by our Quantity Surveyors, Land Surveyors and Managers, and seamlessly integrates the design, setting out and measurement aspects of our work, allowing us to be more efficient and in better control of the tasks in hand.
We are frequently asked to provide budget costings for projects with scant information and no Bills of Quantities. With NRG we are able to carry out a topographical survey of the proposed site, establish top of rock levels from test pits, input the design including finished levels, and from this data calculate the necessary quantities required for the estimate. We are also able to produce 3D renderings and cross sections through the site for the client and highlight any problem areas that might exist. DTM Map allows us to determine changes to the consultant’s proposed earthworks design to balance cut and fill requirements, thus saving the client money, a service which is greatly appreciated. We have found that we can use the software for applications outside of the intended purchase function; an example of which was the design for the extension of the runway on Mustique. Measurement for valuation purposes is another of the software’s strengths, with volume calculations being a particularly powerful tool. Data can be presented in many ways, from cross sections to levels on a set grid within different models, allowing the client’s representative to check and confirm quantities easily, saving both time and effort in agreeing the final account.
On site NRG is extremely user friendly, straight forward and easy to use, and saves our surveyors a considerable amount of time in the field. One aspect they comment on is that once the horizontal and vertical string information has been entered, any point within the proposed survey can be interrogated for chainage, offset, proposed height and the amount of cut or fill required.
The use of strings is extremely versatile, and our surveyors employ them for many applications, even for setting out building gridlines. Client support is another of NRG’s major strengths, and we can speak with one of the programmers should we have a query. This attention to our needs we find invaluable, and unique in an industry dominated by large, faceless software houses.
We are also able to suggest features we would like to see in the software, and this will be taken into consideration and often acted upon and incorporated in future releases. The annual User Group meeting is a good forum to be brought up to date on the latest software release, which I can attest to, having attended every one since their inception in 2003. Of particular value is the ability to have one on one sessions with the programmers for training or advice on any aspect of the software. If I had to sum up the NRG suite of software it would be: powerful, intuitive and user friendly, and for us, indispensable
Having used a number of different civil engineering software packages throughout my 20 year career NRG is by far the best. NRG Survey System delivers a powerful, reliable and intuitive package of engineering and survey software. It has facilitated a range of topographical modelling and volume calculations plus the ability to easily produce cross sections, drainage and road designs.
The software enables data to be imported and exported to and from a wide range of formats and is widely compatible with other software packages and total stations. The software has a number of customisable features which is valuable when reporting data to the client and colleagues.
In addition to this, NRG offer a vast range of support from tutorial videos, software demonstrations, bespoke training and an instantaneous telephone/email support service.
We have used NRG software for the past 20 years for Topographic Surveying and setting out work and we find very user friendly and any issue or questions are answered immediately by the NRG team!
I have been aware of and used information produced by NRG since 2000 as an engineer involved in highway schemes and have been an active ongoing user of the platform since 2007. The software is versatile and easy to use with support from their team in Llanfairfechan and has on numerous occasions helped me deliver complex highways schemes that I have been involved in with every aspect of engineering surveying required for getting a job built.
The PC based software has, as early as 2010, given me key pivotal advantages with the management of simplicity when discussing schemes with Clients and Engineers when the NRG Team integrated the survey system with Google Earth so that people could make a visual assessment on construction impact prior to hitting the ground. It has simplified drainage management for my engineers and with the advent of the Android and iOS App in early 2018 made it easy for me to inform project managers, designers site representatives and clients with their location, offset and chainage when out on site with the Better Information Management of designs in an easy to handle visual format on their mobile devices.
Engineering simplicity is all about knowing what is needed and NRG understands what is needed when it comes to keeping it simple on high profile and fast track contracts. Providing excellent customer service NRG delivers what is required quickly, without fuss and in an easy to understand format for people involved in the delivery of civil engineering projects.
NRG Survey have been very attentive in attending additional rail based features added to their core software. Their professionalism and customer satisfaction needs are second to none.
