Construction management system

A method for producing parts for a plurality of local structures at a construction site of a building, the building comprising at least a first room and a second room, the plurality of local structures at the construction site comprising at least a first local structure at a first location and a second local structure at a second location, wherein the first location is in the first room and the second location is in the second room, the method comprising providing a construction management system comprising:

• a central computing unit providing a building information model that provides data about the construction site and the building;
• a mobile work shop, the mobile work shop being provided at the construction site, comprising a fixed set of machines and being adapted for producing similar parts for similar local structures at a multitude of different constructions sites;
• and
• at least a first and a second hand held laser-based distance measuring devices, each of the hand held laser-based distance measuring devices comprising an electronic distance meter and being configured:
• to measure distances using the electronic distance meter,
• to calculate, based on measured distances, parts dimensions of parts needed for the construction of local structures,
• to be connectable to the central computing unit by means of a wireless data connection,
• to provide data comprised by the building information model to a user,
• to transmit calculated parts dimensions to the work shop in real time, and
• to use data provided by the building information model to guide a user through a measuring operation;
• the method further comprising:
• guiding, by the first hand held laser-based distance measuring device, a first user through a first measuring operation at the first location, the first measuring operation comprising using the electronic distance meter of the first hand held laser-based distance measuring device to measure distances at the first location;
• calculating, by the first hand held laser-based distance measuring device and based on the distances measured at the first location, first parts dimensions for the first local structure;
• transmitting, during or directly after the first measuring operation, the first part dimensions via the wireless data connection to the mobile work shop;
• guiding, by the second hand held laser-based distance measuring device, a second user through a second measuring operation at the second location, the second measuring operation comprising using the electronic distance meter of the second hand held laser-based distance measuring device to measure distances at the second location;
• calculating, by the second hand held laser-based distance measuring device and based on the distances measured at the second location, second parts dimensions for the second local structure;
• transmitting, during or directly after the second measuring operation, the second part dimensions via the wireless data connection to the mobile work shop;
• receiving at the mobile work shop, which is situated at the construction site, the first part dimensions and the second part dimensions;
• and
• producing, autonomously by at least one machine of the mobile work shop, parts needed for building the first local structure and parts needed for building the second local structure, wherein producing the parts needed for building the first local structure comprises taking into account the first part dimensions and the second part dimensions.
