Abstract

The invention provides a system (10) and method for remote assessment of the quality of construction of a structure, for example a multi-storey building (11). The system (10) is characterized Insofar as it includes thermal imaging means (13) for generating thermal images of the structure. The system further comprises the following components; at least one camera system (13) for generating images of the structure; distance measuring means (12) for measuring distances In relation to the structure; primary data processing means (14); storage means loaded with CAD software for execution by said primary data processing means (14); and data transmission means (17, 18) for transferring data from said camera system (13) and said distance measuring means (12) to said primary data processing means (14). The camera system (13) may have integrated, dual capabilities of generating video and thermal images. The method of the Invention includes a step of generating thermal images of a structure using thermal imaging means.

(b) performing a quality check on said structure, representative of at least one pre-determined juncture in time, by carrying out the following sub-steps:
(b1 ) determining an initial spatial reference co-ordinate for said system; (b2) assessing an actual setting-out of at least one of said structural elements by taking linear measurements in relation to said initial spatial reference co-ordinate and said structural element using said distance measuring means; and
(b3) providing a spatial design model of said structural element, comparing said actual setting-out against said spatial design model, and applying trigonometrical formulae to calculate deviations between said actual setting- out and said spatial design model;
(c) generating an image of said structural element using said camera system; and
(d) generating thermal data corresponding to said structural element, using said remote temperature determination means. im 5] A method as claimed in Claim 4, wherein said remote temperature determination means comprises thermal imaging means for generating thermal images of at least one of said structural elements. 22
[Claim 6] A method as claimed in Claim 5, wherein the structural elements comprise concrete structural elements and the method includes assessing properties of said concrete by
importing at least one of said thermal images into said CAD software as a background thermal image;
providing a thermal design of said structural element;
overlaying said thermal design onto said background thermal image to generate a quality drawing;
calculating temperature deviations between said thermal image and said thermal design, thereby to calculate thermal performance data; and displaying said data on said quality drawing.
[Claim 7] A method as claimed in Claim 6, which includes displaying in said quality drawing, in addition to the thermal performance data, data representative of (i) the actual setting-out of the at least one structural element, (ii) the spatial design model, and (iii) deviations between said data.
[Claim 8] A method as claimed in any one of Claims 4 to 7 inclusive, wherein step b is carried out in respect of a plurality of pre-determined critical features of said structure, by means of (i) pre-registering and integrating into said spatial design model, predetermined reference data relating to said critical features of said structure; then, (ii) in accordance with step b2, measuring corresponding critical features of the actual setting-out of the structure, thereby to generate measured data; and (iii) cross-referencing said measured data against said reference data pre-registered for said critical features.
[Claim 9] A new system for remote assessment of quality of construction, substantially as herein described.
[Claim 10] A new method of assessing quality of construction, substantially as herein described.
