“…In order to mitigate such negative effects, many wireless systems, such as ZigBee, are employing Received Signal Strength Indicator (RSSI) technology. However, fluctuations of RSSI due to signal fading significantly affect various applications' accuracy [18]. Experiments presented in this section aim to quantify ZigBee signal's decay in relation to its -root causes‖ providing critical knowledge to design any ZigBee based on-site tracking and control application.…”

-The tenet of TQM is the use of measurements to monitor an operation in order to avoid poor quality outputs. The construction faces unique barriers to utilize effective technologies to capture critical process data in real time. This paper presents the results of extensive field testing of wireless systems to study the effect of the "noisy" environment on sensing and signal propagation. The findings confirmed the hypothesis that construction activities and equipment impact the performance of such networks. In an experimental application on site, ZigBee network to collect data about temperature at pre-designed locations was integrated with an off-site station. Working with the system led to the conclusion that ZigBee is a viable technology to be implemented on the construction site, reliable and easy to use. The concrete crew receiving real time data on temperature from the embedded sensors were delighted as they have never been provided with such new and important information before.

“…Thus, laser scanning and photogrammetry can be used for site representation, RFID and barcodes for collecting actual working hours and modelling for information purposes and updating planned data [45]. The control of the status of materials in the job sites by means of RFID technology is a useful tool to show a 4D CAD model of the building under construction and to compare the planned model with the built one [46]. To visualize the construction progress in real time, other authors [47] propose the integration of building information management (BIM) models and augmented reality.…”

Radio frequency identification (RFID) technology has been widely used in the field of construction during the last two decades. Basically, RFID facilitates the control on a wide variety of processes in different stages of the lifecycle of a building, from its conception to its inhabitance. The main objective of this paper is to present a review of RFID applications in the construction industry, pointing out the existing developments, limitations and gaps. The paper presents the establishment of the RFID technology in four main stages of the lifecycle of a facility: planning and design, construction and commission and operation and maintenance. Concerning this last stage, an RFID application aiming to facilitate the identification of pieces of furniture in scanned inhabited environments is presented. Conclusions and future advances are presented at the end of the paper.

“…Their system is able to assess progress control with minimum human input. In [5] a methodology for indoor location identification and material tracking based on RFID is presented. This automated approach enables acquisition of data about construction project status in almost real-time and detects the locations of worker and material with 100% accuracy.…”

-This paper deals with the adaption of construction schedule due to real-time data. This real-time data needs to be evaluated regarding the effects on the schedule. If significant delays or other problems are identified, the schedule should be adapted. That means that under the existing condition a new schedule needs to be generated. Thereby, different constraints of the target schedule like contracted delivery dates, milestones or resource allocation should be considered. In the presented approach these additional constraints are modeled and integrated into a simulation model which represents the planned target schedule. By applying simulationbased optimization a new efficient schedule is generated considering existing and additional so-called target constraints. If the identified delays are that large, such that an adaption considering all significant constraints is not possible, some constraints, like resource capacity or shifts, can be relaxed. The proposed concept for reactive adaptation of construction schedules by applying simulation-based optimization is verified by a standard construction schedule example.
