Abstract: A system and associated methodology for predictive construction cost estimation. Path data, extracted from a vector-based data source, is decoded and correlated into a point-map-to-line-segment array providing the ability to predictively snap a cursor on a user interface to points and/or line segments illustrated in the vector-based data source. Once identified and committed to by the user, the invention thereafter links additional snapped points/line segments/polylines enabling the user to quickly and efficient move throughout the data source crating a timely and accurate construction estimation.

Abstract: A guard for a conveyor assembly, with the conveyor assembly having a pair of spaced apart side frames and at least a pair of adjacent conveyor zones, with each conveyor zone comprising a pair of rollers about which a conveyor belt is disposed with the rollers of the zones mounted between the side frames and a gap formed between the conveyor zones. The guard has an elongate lower portion configured to mount between the side frames in the gap, with the lower portion having a mounting receptacle configured to receive a connector for mounting the guard between the side frames. The guard also includes at least one elongate outwardly angled side extending upwards from the lower portion to a top surface, with the angled side configured to be disposed adjacent one of the rollers of one of the conveyor zones.

Abstract: A receptacle exchange for a pick or put receptacle and method for exchanging a pick or put receptacle includes a process location at which an operator processes a receptacle by picking articles from or putting articles to a receptacle. A lift moves a receptacle from a supply location to the process location. An extractor retrieves a receptacle from the process location to an extracted location. A first drive elevates the lift between the supply location and process location and moves the extractor between the process location and extracted location. A second drive moves an inclination of the extractor. A control controls the first and second drives.
