Construction cost estimators are confronted with the challenging task of estimating the cost of constructing one of a kind facilities. They must first recognize the design conditions of the facility design that are important~i.e., incur a cost! and then determine how the design conditions affect the cost of construction. Current product models of facility designs explicitly represent components, attributes of components, and relationships between components. These designer-focused product models do not represent many of the cost-driving features of building product models, such as penetrations and component similarity. Previous research efforts identify many of the different features that affect construction costs, but they do not provide a formal and general way for practitioners to represent the features they care about according to their preferences. This paper presents the formal ontology we developed to represent construction knowledge about the cost-driving features of building product models. The ontology formalizes three classes of features, defines the attributes and functions of each feature type, and represents the relationships between the features explicitly. The descriptive semantics of the model allow estimators to represent their varied preferences for naming features, specifying features that result from component intersections and the similarity of components, and grouping features that affect a specific construction domain. A software prototype that implements the ontology enables estimators to transform designer-focused product models into estimator-focused, feature-based product models. Our tests show that estimators are able to generate and maintain cost estimates more accurately, consistently, and expeditiously with feature-based product models than with industry standard product models.

“…Slaughter, 2003 proposed a Dynamic Process Simulation Model of Construction Activities, which could generate the impact of design alternatives on construction cost/schedule/safety. The safety in the model was defined as the index of the exposure of workers to dangerous conditions calculated from the task duration matched to the OHSA-identified causes of worker injury 15 . But recent research showed that the occupational accidents suffered by construction workers at different hours of the day are different 14 , thus the task duration may not reflect the situation in this regard.…”

Purpose One of the potential solutions for designers' lack of safety expertise in design decision is utilizing IPD to allow for constructor input. But how this is to be done is often unclear because few cases from either practice or research can be found. In this study we tried to develop an IPD-method to facilitate 'safety in design' with the contractor's knowledge using an object-oriented programming (OOP) approach for design decision based on BIM. Method Our principal research method is simulation of the decision process in OOP2 in a case study. The integration of contractor's knowledge in construction safety is achieved by setting parameters for construction safety investment with contractor's input into a construction safety component library (CSCL) e.g. scaffolds, boards, barriers, etc. under the proposed IPD-framework. Results & Discussion A prototype of CSCL using one OOP-language, C#, is developed in Microsoft Visual Studio 2010 to Autodesk Revit 2012 with a completed construction project for demonstration. The results show that CSCL is a semiautomated tool with contractor's knowledge of construction safety for design decision. It is consistent with the theory that BIM is not only a type of software but a knowledge repository for in-depth collaboration, information sharing and knowledge re-use among all parties involved in a project. New issues and rethinks including level of detail (LoD) on company's library, IPDevaluation metrics, and BIM-development method addressing construction safety management, are also recommended in the final part.

“…It is found that a number of researchers have illustrated how designers have implemented collaborative work via 3D modeling with contractors to enhance constructability ( [5], [7], [11],). In that sense, we believe that BIM is one of the most recent technologies that has gained acceptance in the AEC industry.…”

The key role in safety management is to identify any possible hazard before it occurs by identifying any possible risk factors which are critical to risk assessment. It is well known that falsework (temporary facilities) in construction projects is fundamentally important. This planning/assessment process is considered to be tedious and requires a lot of attention due to the following reasons: firstly, the installation and dismantling of those facilities are one of the high risk activities in the job sites. Secondly, temporary facilities are generally not clearly delineated on the building drawings. Therefore, it is our strong belief that safety tools have to be simple and convenient enough for the jobsite people to manage them easily and be flexible for any occasions to be occurred at various degrees. In order to develop a safety identification system of temporary facilities, this research utilizes the BIM technology in retrieving important information by importing data from BIM models and use it in the safety planning stage.
