About

SC4W (Survey Calculations 4 Windows) is a mathematical software package used to process dimensional control data-point surveys during large oil & gas, aviation, shipping, wind turbine and other civil engineering projects. 

It also has a set of geometrical functions, such as coordinate transformation by least squares, that are useful in other contexts involving 3D analysis.

Services

As well as sales and support for SC4W, we also offer online and on-site training in SC4W and dimensional control.

History

SC4W began life as SC4B, a program which was originally commissioned from Alan Coulson by Blom Oppmaling in Norway, to bring together a set of common survey processes and maths computations used in dimensional control and offshore surveying, dating as far back as the 1970’s. SC4B was designed as a simpler and cost-effective alternative to more complicated and expensive software solutions available from survey equipment vendors. It has grown in scope and functionality, based on collaboration with experienced surveyors, and has since been used on many major oil and gas projects. Around 200 individual surveyors and survey organisations around the world use SC4W regularly on a wide assortment of civil and marine construction projects.

In 2000, SC4B was rewritten as SC4W to enable it to run on Microsoft Windows 95, and has continued to run successfully on every version of Windows since then.

In March 2024. SC4W was redeveloped as SC4W2 incorporating all the original software features packaged with a new graphical interface displaying coordinates in a 3D grid. The Microsoft .net platform allows further extensions to SC4W creating greater opportunity to develop bespoke user functionality. The software licensing has moved to a server based licensing system, eliminating the need for dongles and offering easy purchasing and regular updates.
