Project Summary
Parsons Brinckerhoff has been involved in a number of large scale, high 
profile projects involving the design of roads, drainage, sewer, water and other 
associated infrastructure, as well as bulk earthwork modelling. Their project 
teams used 12d Model software to overcome a number of complex and ‘non-standard’ 
challenges, often requiring innovative solutions. Due to the size and nature of 
these projects, they were required to work closely with a number of other 
consulting engineering companies, with the need for their software of choice to 
interact seamlessly with the design software used by other companies working on 
the projects.
 
The Challenge
It was imperative for the team to be able to check for clearance and possible 
clashes between services designed in 12d Model, and those designed in other 
packages. With limitations on compatibility of import/export mechanisms between 
various software packages, innovative methods were required to allow design data 
to be transferred from 12d Model to other packages, and vice-versa. This was 
required predominantly for transfer of three dimensional pipeline data elements 
between packages, for drainage, sewer, water and other services. Another 
innovation was the use of 12d to successfully model complex electrical and 
chemical box culvert systems, which the team had never previously considered 
attempting. 
 
The Solution
Creation of detailed procedures was important, in some cases with step-by-step 
user guides to allow any project team members to facilitate the transfer of 
data. The procedures enabled 12d Model to produce .csv (comma separated values) 
data in a format which other software can use, as well as to read in .csv data 
in its original output format from the other package. A macro was developed to 
output three dimensional pipe data designed in 12d Model, into a .csv file which 
other packages can read. Electrical and chemical box culverts were created with 
an improvised approach using drainage strings, with the Drainage Network Editor 
used to specify the height and width of the culverts. The Drainage Plan Plot 
function (with a modified plot parameter file) was used to give the culverts the 
correct geometric representation showing actual internal dimensions of the 
culvert, allowing service clash checking to be undertaken in 12d Model.
 
The
Result
Using 12d Model software, this innovative team was able to overcome a number of 
complex and ‘non-standard’ challenges, particularly on very large projects. They 
were able to work closely with a number of other consulting engineering 
companies, with 12d Model interacting seamlessly with the design software used 
by the other companies.
