以BIM實現工作包結合現地感測技術於複雜專案資訊流之改善

Abstract

由於創新設計、新興技術崛起以及日漸精進的管理流程，專案過程記錄的資訊不斷地增加，而這些資訊也幫助專案的利害關係人做決策。然而在決策時，很可能因資訊量過多而遺漏或不考慮部分的資訊。而這些沒納入決策的資訊，本質上是一種資源的浪費，因其不為專案增加價值。由此可知，一套有效管理資訊流的方法，是減少資訊浪費的關鍵。本研究主要目標為發展一套創新的資訊環境，以減少潛在的資源浪費，從而改善專案中的資訊流。 本研究開發了一套縱整專案資訊的通用資料環境（CDE），容納來自各專業的資訊。在提出的通用資料環境中，我們開發了一套基於BIM的現地感測方法，來輔助決策時所需的現地資訊。此外，我們也開發了一套基於BIM的工作包方案，用於整理各專業的資訊。他能以一系列的工作包來管理各專業的現地任務，並基於工作包內部的共通屬性自動關聯，作為跨專業資訊交流的核心。因此，在所提出的CDE中，現地感測資訊和工作包內的資訊會井然有序且相互參照。在決策時，也能有相關的專案資訊來輔助判斷，減少資訊的浪費，改善複雜專案的資訊流。 本研究為專案生命週期中的利害關係人提供了理論和實際意義。它為專案提供了持續的資訊流，將工地現場資訊流向辦公室，並將這些感測器收集的數據轉換為能輔助決策的資訊。此外，各利害關係人的資訊也能藉此被妥善整理並自動關聯，提供了一種創新的方法來整理和分析多方的專案資訊。

The amount of information in a project can increase significantly due to innovative designs, increasing adoption of emerging technologies, and complicated management processes. Although this information can be made available to all project stakeholders, when decision-making occurs, some information is neglected or not considered. The omitted information is essentially a wasted resource, which does not add value to the project. An effective management of information flow is the key to reducing wasted information, yet it accounts for the largest proportion of issues during a project lifecycle. The primary goal in this research is to develop an innovative data environment to reduce the potential wasted resources so as to improve the information flow in projects. This research develops an integrated common data environment (CDE) to accommodate the project information from multiple sources. In the proposed common data environment, the BIM-based field sensing approach is developed to monitor site conditions which serves for the information demands when decision making. Besides, the BIM-enabled work packaging approach is developed to organise the information from various disciplines and working schedules. A series of work packages could be layouted to specify the tasks, and the linkages are automatically generated afterwards on the basis of the properties inside. Therefore, the field sensing information and work packages are well-organised and cross-referenced in the proposed CDE. It provides relevant information as much as possible when decision making occurs which is considered to be versatile and capable of reducing information waste. In consequence, the improvement of information flow in complex projects is achieved. Theoretical and practical implications of this research are provided for stakeholders along with the project lifecycle. It provides a continuous information flow to stream site conditions from site to office and interpret the sensor data in useful information to support the decision making. Besides, project information from multiple stakeholders is organised and linkages among project information are automatically generated which provides a novel approach to arrange and analyse multiple sources of project information. The versatility of the common data environment shows an insight of integrating multiple emerging technologies to suffice various demands of information.
