DESIGN CENTRE is the heart of the system which includes the Graphical & Topographical engines. It allows you to create new drawings with supporting digital terrain modeling data. This module is a prerequisite in order to run one of the other design modules.
SURVEY + TERRAIN is a Digital Terrain Modeling module which provides interactive earthworks design and calculations. This module includes cut/fill optimisation and rendered three-dimensional views with light source, material colours and textures.
ROADS is a comprehensive design module that provides interactive embankment design and calculations. Suitable for urban & rural roads, dams, freeways, airports & railways. "Drive" down the completed road in a rendered 3D view to check for blind rises and other anomalies.
SEWER is a foul water network analysis & design module which combines interactive drawing functions with powerful design functions. The program supports a complex system of inflows and overflows.
STORM is a runoff event network analysis & design module which can model complex overflows including the dual drainage model. Runoffs can be attenuated by means of reservoir routing with full reporting of reservoir depth, storage and outflows.
WATER is a powerful module for the analysis & extended time simulation of fluid handling networks with pipes, valves, reservoirs and pump stations.
MAP is a fast and easy to use GIS module. Exchanging data between MAP and our CAD and design modules allows you to use MAP as an editor for ArcInfo and MapInfo data.
TURN is a powerful vehicle simulation program to track low speed manoeuvres for a wide range of standard and user defined vehicles, including aircraft and forklifts. Various paths can be tracked, including centre line track path and swept paths in forward and reverse simulation.
CAD is an add-on module to DESIGN CENTRE that gives you the full functionality of AllyCAD, our fast, powerful & very easy to use CAD program.

It is common that civil engineer needs to prepare drawings. It is carried out after the design of structure or civil works has been completed. How to have a proper drawing numbering system in order to has better presentation? Below are some tips on drawing numbering system.
1. Time control.
It is useful that a project starts with month and year. As for example, if an awarded project on say 12 April 2007 than your drawing number may 042007 and not 120402007, because it may become to complicate. On the other hand, you can select year as control item 2007. Initial drawing number will be 042007
2. Client name control.
Let say, your client is ABC Company and with item 1; your drawing number will be ABC/042007.
3. Engineering field control.
Say your project is building a unit of structural building. You may further add with "ST". "ST" is abbreviate for structural. You can use other abbreviation as your preference. Then drawing number will be ABC/042007/ST. For civil works such as earthwork, you can use "EW", water work use "WT", sewer work use "SW", drainage work use "DR" etc.
4. Type of structural element control.
When you design the building structure, the structural elements may consist of pad footing foundation, column, beam, slab etc. You have to use a list of abbreviation for the structural elements such as pad footing foundation-"PF", column-"COL", beam-"BM" and slab-"SB". For instance your drawing is showing beam details, then your drawing number will be ABC/042007/ST/BM01 (first drawing), ABC/042007/ST/BM02 (second drawing) and continue with this notation. This type of arrangement is good for adding any new drawing into every section without disturbing the overall drawing number. As for example, you are using only one type of notation say ST for all structural elements, then your drawing number will be ABC/042007/ST/01, ABC/042007/ST/02, ABC/042007/ST/03 …
When or during the project in progress, there will be tendency of amendment happened. If you need to add one sheet of beam drawing into your project drawing number and the beam drawing numbers are in the range of ABC/042007/ST/03 to ABC/042007/ST/04. Total number of drawings says 10 numbers; last drawing number will be ABC/042007/ST/10. How to add a drawing after ABC/042007/ST/05? You have to add it after ABC/042007/ST/10 i.e. ABC/042007/ST/11. However, it will not in the sequence of beam drawing arrangement. If you have more break down as mention earlier, then it is easy to add a new drawing into each section and for the current case is ABC/042007/ST/BM03. It will not affect the presentation of drawings.
5. Drawing amendment.
When there is an amendment on a particular sheet of drawing say drawing number is ABC/042007/ST/02. How will be the amendment to be shown on drawing number? One suggestion is using abc notation. ABC/042007/ST/02a is first amendment; ABC/042007/ST/02b is second amendment etc.
In short, the formula for drawing number will be
[name]/[time]/[engineering field]/[type of element][numbering][amendment].
When you follow the numbering system as mention, your project drawing numbering can be easily to be interpretation.

A new kind of concrete called Ductal will allow bridges to hold more weight and last longer. Made of a mixture of sand, cement, water, and small steel fibers, it is 10 times more expensive than traditional materials but also stronger and virtually impermeable, helping bridges become more durable.
AMES, Iowa--Bridges take a beating, and it can really break the bank to repair them. Now, researchers are breaking bridges to learn how to build them better and save you money.
Justin Doornink spends his mornings underneath bridges. He's an engineering student and, as part of his homework, he's installing sensors to measure the impact of traffic on the bridge. He's trying to figure out how to strengthen the structures. One option is ultra-high-performance concrete, which is made from sand, cement, water and small steel fibers.
Brent Phares, a civil engineer and associate director at the Iowa State University Bridge Engineering Center in Ames, says, "It's much, much stronger. It's basically impermeable to water. What those two things mean is you can build a bridge that has a higher capacity and should last a longer period of time."
Brent did a small-scale test with the new concrete, pushing it to its breaking point. It held close to 595,000 pounds -- that's more than seven semi trucks. The material costs 10-times as much as traditional concrete, but you need less of it, and it lasts longer.
"You're never going to advance the state-of-the-art unless you do some research, try some things out, maybe take some risks and see what might ultimately save the taxpayers money," he says.
