press release from May 2010 for tbvs version 1.1

The acronym tbvs stands for Tiefbauverwaltungssystem. The software has a German interface and enables the user to do calculations and (mobile) measurements in the network construction. The program is free available and for free. It is client-capable and combines the discrete areas planning, measurement and project management. Technically it is a client-server system which is written in an object-oriented language.
After one year development the software is available since october 2008 as version 1.0.

Generally tbvs does addresses itself to companies deallng with civil and underground engineering and especially to utilities (EVU).

Energy supply companies all over the world are investing great amounts of money in the construction, enlargement and maintenance of their networks for gas, water and electricity. As this costs billions of dollars it is in the interest of the utilities to carry the building contracts out as fast as possible. It is necessary to estimate the costs as detailled as possible, to calculate the budgets as accurate as possible and to do a quantity survey as easy as possible. A quick calculation and a well-trimmed measurement are very important as lots of utilities delegate a great amount of the tasks in underground engineering and assembling as awarding authority to contracting companies.
The program tbvs supports exactly these vital actions and allows the user to make quick and clear calculations, detailled measurements and accurate biddings and billings.
tbvs accompanies the user through the whole cycle from the planning of a construction site, from the calculations and measurements up to the point of the billing. The individual projects can be split hierarchically into three levels - in segments, stages and sections. The individual booking can be assigned to one of the three modes for underground engineering, assembling or can be classified as material.

The clearly laid out application windows can be opened intuitively. Calculations and measurements can be opposed each other comfortably.
Multiple data entries are annoying, boring and proning to errors. In order to avoid them the software supports so-called user-definable models. These models contain calculation specifications which can be executed again and again for any construction site. The models are displayed as formulas from the program and automate the data input. The user merely fills out the formula and enters the masses of the positions out of the specifications which are mentioned in the model.
Additionally allows tbvs a mobile measurement : The data for the measurement are therefore copied to the mobile computer. The copied projects are now locked and can not be changed by other users until the mobile computer copies the measured data back on the server machine.

But there are lots of more features. For example includes tbvs, which has no problems with lots of data, several additionally integrated modules :

A module to plan material in advance allows to book precisely timed the material which is designated for the construction sites.
Then there is a module which integrates tenders in order to determine the price of a building lot of several companies. Companies assigned to a tender can enter their prices comfortably by the eClient module and after the tender period has finished it is possible to include the determined prices by a push of a button into the price lists kept by tbvs. Tenders can be opened for whole projects, parts of projects or for annual contracts spanning whole specifications.
Another module is the eClient-module which facilitates the calling for tenders for several service providers. The companies which participate the tender can then add comfortably prices to the service items of the tender via internet. The user of tbvs can then transfer the online determined prices in the database by at merely a push of a button.
The eClient module is a comfortable way to offer companies the possibility to enter their prices online.
By means of the integrated module for model management with versioning you are able to keep track of the version history of the individual models. The application is now able to apply the right version previously used for the affected section.
Some dozens of forms build up the project management module, which gives the user the possibility to store his precious project related data in the system.
tbvs now offers six different price categories. Regular company prices and their history, project related prices and their history, prices of annual contracts and prices used in the tenders. Even after years the program assigns the prices correctly to the relating specification. This is not the rule for programs of this genre.
Then there is a billing module which manages the bills, which can be calculated after the measurement.
Also there exists a patching tool which disburdens the main user, the system and the database administrator as database patches are now handled automatically.
A generator for test data allows now the simulation of big amounts of data so that the user can draw conclusions from the data to the reaction time of tbvs.

tbvs is an object oriented client-server software, which is written in PHP. The application server can be a computer with 500 MHz and 32 MB RAM. The server needs either on Linux an easily installable LAMP environment or when running on a Microsoft Windows (c) platform a WAMP environment. LAMP is an acronym for a software bundle consisting of Linux, Apache, MySQL and PHP whereas the first letter of WAMP stands for Windows (c). The clients are frugal in terms of requirements, too as they demand merely an internet browser in order to access tbvs and its precious data. Mobile clients need on the other hand their own LAMP- or WAMP environment in order to allow the user to do mobile measurements.
Having installed the LAMP or WAMP environment the administrator copies the application files into the apache web directory and generates the needed MySQL database. After creating the users they can use the program.

The program tbvs can be downloaded from http://sourceforge.net/projects/tbvs/. On this site there are some screen snapshots from the application, too. On the project web site http://tbvs.sourceforge.net/ there are more informations about tbvs. The project wiki resides under http://scratchpad.wikia.com/wiki/Tbvs. There can be found the illustrated application's manual, too.

The program tbvs-hr enlarges tbvs. the acronym 'hr' stands for human resources. tbvs-hr allows the user to plan and manage resources graphically with the mouse in an electronic year planner. The application aims to reduce expensive over capacities and to avoid under capacities by assigning the available resources consistently to the calendar. This piece of software runs on Linux, too but is a KDE application. The in C++ programmed source code and the binary are available on the site http://sourceforge.net/projects/tbvs-hr/. Screen pictures can be seen there, too. The illustrated manual can be found under scratchpad.wikia.com/wiki/Tbvs-hr.
