Abstract

The invention pertains to a construction management system for the construction of a structure, comprising a plurality of sensor means adapted to detect events at a building site of the structure, a central computing unit providing a three-dimensional model of the building site, and at least one displaying device that is adapted to display the three-dimensional model to a user, wherein the sensor means is adapted for generating data comprising information about a detected event, the system comprises communication units adapted to transmit a message comprising the data and a location information to the central computing unit, assign coordinates in the three-dimensional model according to the location information, evaluate options for reacting on the event by analysing the data, assign evaluated options to the data, and display a note which is related to evaluated options to the user in real-time at the assigned coordinates in the three-dimensional model.

First claim

What is claimed is:

1. A construction management system for the construction of a structure, the system comprising:
a plurality of sensor means adapted to detect events at a building site of the structure and to generate data comprising information about a detected event,
a central computing unit providing a building information model comprising:
a three-dimensional model of the building site or of the structure,
a construction plan comprising a target state of the construction of the structure,
information about a current construction state of the structure, and
information about participants in the construction of the structure;

at least one displaying device that is adapted to display the three-dimensional model to a user; and
a plurality of communication units adapted to transmit a message comprising the data and a location information to the central computing unit,
wherein:
the construction management system is configured to assign coordinates in the three-dimensional model according to the location information,
the central computing unit has an evaluation algorithm adapted to evaluate options for reacting on the event by analyzing the data using information from the building information model,
the system is adapted to assign evaluated options to the data, and
the at least one displaying device is adapted to display a note related to the data and to evaluated options to the user in real-time, wherein the note is displayed at the assigned coordinates in the three-dimensional model.

2. The construction management system according to claim 1 , wherein the sensor means are adapted to generate the data automatically, or the communication units are adapted to generate the message automatically.

3. The construction management system according to claim 1 , wherein the sensor means comprises at least one of:
a camera,
a distance meter,
a motion detector,
a smoke detector,
a thermometers,
a hygrometer, or
an input means configured to allow an input by an operator.

4. The construction management system according to claim 1 , wherein the sensor means are configured to generate the location information comprising information about a location of the event.

5. The construction management system according to claim 1 , wherein the central computing unit comprises at least one server computer, wherein the communication units are adapted to transmit the message to the central computing unit by means of an internet connection, and wherein the at least one displaying device is adapted to receive the data from the central computing unit by means of an intranet connection.

6. The construction management system according to claim 1 , further comprising a plurality of displaying devices each being configured to display the three-dimensional model with the note to a user in real-time, each user having a role in the construction of the structure, wherein the evaluation algorithm is adapted to evaluate, based on the roles, on which of the displaying devices a note is to be displayed, and the system is adapted to assign evaluated options to the data for each displaying device.

7. A method for linking data to a building information model, wherein the data comprises information about an event occurring at a building site of a structure and the building information model comprises at least a three-dimensional model of the building site or of the structure, a construction plan for the construction of the structure comprising a target state of the construction of the structure, information about a current construction state of the structure, and information about participants in the construction of the structure, the method comprising:
generating a message comprising the data and a location information;
transmitting the message to a central computing unit comprising at least one server computer;
evaluating options for reacting on the event by analysing the data using information from the building information model, and assigning evaluated options to the data;
assigning coordinates in the three-dimensional model to the data according to the location information;
providing the data from the central computing unit to at least a subset of the displaying devices; and
displaying the three-dimensional model simultaneously to a plurality of users on a plurality of displaying devices, each user having a role in the construction of the structure, wherein a note which is related to the data and to the assigned options is displayed in the three-dimensional model at the assigned coordinates in real-time,
wherein the options for reacting are assigned to the data for each displaying device individually and it is evaluated, based on the roles, on which of the displaying devices a note is to be displayed.

8. The method according to claim 7 , wherein the data is generated automatically by a sensor means detecting the event, and the options are evaluated automatically by an evaluation algorithm of the central computing unit.

9. The method according to claim 7 , wherein the location information comprises information about a location of the event, a sensor means detecting the event, or a communication unit generating the message.

10. A method according to claim 7 , wherein the message comprises information about a time of the event or of the detection of the event, wherein information about the time are considered in evaluating options for reacting, and wherein the note is also based on the information about the time.

11. A method according to claim 7 , wherein displaying the note in the three-dimensional model comprises presenting the data and evaluated options to the user.

12. The method according to claim 7 , wherein displaying the note in the three-dimensional model comprises visualizing an icon at the assigned coordinates in real-time, wherein the icon is user-selectable, and upon a user-selection of the icon, a notice is visualized based on the message.

13. The method according to claim 7 , wherein the data comprises picture data and/or audio data.

14. A computer program product comprising programmable code which is stored on a machine-readable medium, and having computer-executable instructions for performing, at least the following steps of the method of claim 7 :
evaluating options for reacting on the event by analysing the data, using information from the building information model, and assigning evaluated options to the data;
assigning coordinates in the three-dimensional model to the data according to the location information;
providing the data from the central computing unit to at least a subset of the displaying devices; and
displaying the three-dimensional model simultaneously to a plurality of users on a plurality of displaying devices, each user having a role in the construction of the structure, wherein a note which is related to the data and to the assigned options is displayed in the three-dimensional model at the assigned coordinates in real-time, wherein the options for reacting are assigned to the data for each displaying device individually and it is evaluated, based on the roles, on which of the displaying devices a note is to be displayed.
