A vacuum-assisted pole sander includes a sanding means attached at the end of the main pole, which in turn is supported in its middle section by a support pole. Both the support pole and the main pole are hollow and adjustable in length. The vacuum is transmitted from the sanding means of the device through the main pole to the vacuum connector in the supporting pole such that a vacuum can be attached on to ensure dust removal during operation. The combination of the support pole and the main pole is designed in such a way that the entire device is supported on the floor of the building under construction while allowing the operator to move it easily back and forth to achieve sanding of the ceiling. The support pole has a non-slip cap on its lower end and an angle connector on the other end. The angle connector is rotatably attached to the main pole such that it ensures the ability to swivel and at the same time provides a fluid communication between the inside portions of both the main pole and the support pole. The support pole is equipped with a vacuum attached for connecting to the suction means. The lower end of the main pole is equipped with vacuum strength adjustment means.

A method and remote-controlled reflector device for layout reference and axis lines is provided for use preferably in high building construction industry. The reflector device includes a mirror capable of rotating about its horizontal and vertical axes as controlled by an instrument man standing with a remote controller and a theodolite at a first location, such as on the ground or a lower floor of the building. The reflector device is positioned over the edge of a floor of a building under construction such as to be in direct view from both the first location and the second location where the new axis line marking are to be placed by the rod man. The mirror is first rotated by the instrument man such as to reflect the view from the theodolite back upon itself to verify its proper alignment with the base axis line. The instrument man then remotely rotates the mirror towards the second location such that the inflected line of sight is formed from the theodolite through the mirror defining an inflection point and advises the rod man where to place the mark for the new axis line. The procedure is then repeated at other locations as needed. The method allows more precise and safe transfer of lines without the need for the rod man to stand close to the edge of the building. Proper verification of the existing layouts is also described.

The invention provides a means for a User to enter a structure/building under construction, on a computer enabled device, display a 2D floorplan or map of the realworld [3D] structure in which User is standing, and User can indicate on the display, via a mouseclick, for example, the User's approximation of User's realworld location. Then, User can acquire an image, and the display will indicate to User how to more accurately select the position from which the image was acquired. The information—i.e. both the acquired image and the imaging position information on the floorplan—can be stored, and retrieved and re-displayed, by clicking the interactive floorplan of the structure.

In an alternate embodiment, the invention provides that in addition to an acquired image, User may retrieve a reference image, and compare the acquired image with the reference image, and refine the position indicator on the interactive display of the floorplan, where the precision is sufficient to enable a Thru-view™ display.
