Abstract

The reinforcement concrete structures exposed to sea environment suffer from corrosion of steel bars due to chloride ingress. It's generally assumed that the diffusion of chloride ions follows Fick's second low. Traditionally such partial differential equations are largely solved using numerical methods, such as Finite Element (FE) Method and Finite Difference (FD) Method. Although these methods are robust and efficient, but they exhibit some noises in the initial time steps results. In the present research, a detailed description of element-free Galerkin (EFG) method and its numerical implementation in one and two-dimensional models is presented. In this method, Moving Least Square (MLS) approximation is used to weak form the equation. So, the independent variable, chloride content, and its gradient are continuous in the entire domain. By comparing EFG results with FE and FD and obtainable analytical solutions in special cases, it's seen some advantages in using this method such as fewer noises in the initial time steps results and smoother curves, increasing the rate of convergence. It also could be achieved to higher resolution in the interfaces such as coating on the surface of concrete.

Citation: Pereira, E., Taghaddos, H., Hermann, R., Han, S., & Abourizk, S. A CONCEPTUAL ACCIDENT CAUSATION MODEL BASED ON THE INCIDENT ROOT CAUSES.

 

Abstract

The measurement and control of incident root causes allows for proactive activities to mitigate risk in advance. In practice, however, it is difficult to identify and collect data that represent the root causes due to the complexity of incident occurrence processes. Despite previous studies on incident causation modelling, the identification of root causes in practice still relies on the investigator’s subjective opinion. This research presents a conceptual model that explains the causal relationships between the root causes and the site unsafe level, and eventually assesses incident investigation processes. A case study was conducted to evaluate the 13 root causes in a company’s investigation practice. The causal relationship between the root causes was observed based on the company safety database, interviews, and literature review. Then, the detailed model, which explains the incident occurrence process, was explored. Additionally, a hypothetical simulation model that allows for evaluation of the influence of each root cause on the safety level was built and tested to discuss the potential use of the conceptual model. Based on the company database, this paper also suggests and discusses the types of data to measure the root causes in practice. The model demonstrates that not only do safety personal and safety strategies affect the site unsafe level, but other factors also do, such as procurement, engineering, human resources, etc. As a result, the proposed model can be used to help identify the root cause in incident investigation practice and to develop strategies to improve safety performance.

Abstract

Industrial construction includes a wide range of construction projects, such as petroleum refineries and chemical plants. These involve several trades, such as civil, mechanical, and electrical. Different trades carry out different tasks on these projects, and often depend on scaffolds to access their work areas. Quantification of scaffold requirements of large projects is difficult because of variability in work area heights and congestion and the multiple trades that need to be serviced by the scaffold system. Traditional estimating methods rely on percentages of direct trade hours or volume of work area and usually result in significant deviation from real scaffold costs. The study presented in this paper aims to develop better understanding and estimates of scaffold needs for industrial construction sites, based on analysis of data collected from a mega-project over the course of two and a half years by a major contractor. The study seeks to discover patterns and reliable correlations that may exist between required scaffold hours and other work attributes that can allow for development of a reliable estimation model. The paper presents the results of initial analysis and exploration of data mining experiments, in addition to the challenges faced and future research recommendations.

Abstract

Path planning is crucial in constructability analysis and heavy construction equipment scheduling, particularly in industrial plants. The main purpose of construction equipment path planning is devising the shortest path between its initial and aimed location. This suggested path is supposed to be safe and collision-free. The current planning practice, even in industrial projects whose sites are extremely congested, is manual based on expert judgment. Thus, this sophisticated manual process is not only prone to errors but also time-consuming. This research presents an automated path planning approach based on an obstacle avoidance technique in robotics to support the decision-making process. The proposed methodology finds the shortest path for the planar motion of any convex 2D object. It assumes continuous translational (i.e., X and Y directions) and discretized rotational motions for the object. Two case studies are also presented to illustrate and to validate the proposed methodology.

Abstract

Using BIM technology is well established in construction projects, especially in industrial projects where a maze of pipes and modules have to be installed in congested work areas under tight time schedule. BIM offers potential benefits (e.g. visualization, collaboration, alignment …etc.) that can be key for complex project success; however, these benefits have not been fully implemented in industrial projects. The authors worked last two years closely with a construction company which specialized in oil and gas projects- trying to discover ways to maximize utilization of knowledge embedded in BIM models. Though the partner company has used BIM for long time, we noticed many obstacles that hinder reaping the full benefits of BIM for construction planning and control. These obstacles are related to the ability to extend a model by adding new attributes and to link the model to data from external sources (e.g. cost or schedule control information systems). This paper discusses these obstacles, illustrates implemented short-term solutions to work around and mitigate these obstacles, and finally concludes by proposing using semantic web as a long-term solution to overcome these obstacles and clear the path for gaining all potential benefits during industrial projects construction.

Abstract

With the fast advancement of information technologies (IT) in recent decades, the informatization level of various industries is enhancing. In the construction industry, building information modeling (BIM) has created a new evolution in planning, progressing, and managing construction projects. However, access to BIM software (e.g., Navisworks) on a remote construction job site is not always feasible. This study aims to develop a smart controller that can portrait the current snapshot on a job site based on the GPS data received from a portable device (e.g., smartphone). This controller captures a rendered high-quality image by mapping the GPS based data and the model’s local coordinates together. Finally, such images would be reported to the crew on the site via cloud saving systems. The developed results facilitate employing the BIM model for different people involved on a job site (e.g., crews, foremen) for employing BIM for planning, building, controlling, and progressing purposes.

Abstract

Large, complex construction projects, such as industrial plant construction, are not well suited to discrete event process interaction simulation. The authors present a distributed simulation of industrial plant construction using separate modules inter-linked via the High-Level Architecture (HLA). This enables the capture of all features, resources, and processes required to design, build, and maintain a facility, and an HLA-based approach simplifies collaborative development and improves reusability of components. The proposed methodology for simulating industrial construction is validated using COSYE, a Construction Synthetic Environment developed at the University of Alberta.

Abstract

As of November 2012, the Alberta government listed 53 oil and gas, oil sands, and mining construction projects either proposed or currently under construction. These industrial plant construction projects have an estimated value greater than 105 million dollars. A common construction method employed for industrial plant projects is fast-track construction, which is used to reduce construction time. Contractors begin fast-track construction with highly generic scheduling information. This high-level schedule turns into a lower level schedule as more detailed information becomes available. From a contractor’s perspective, a challenge faced using fast-track construction is the visualization of generic and constantly changing project schedules. This paper discusses the use of a Plant Information Modeling (PIM) system, designed to create a 4D animation to visualize project schedules for fast-track industrial plant construction projects. The proposed PIM system creates a modified project schedule by obtaining specific information from a generic construction schedule. Obtaining the information involves grouping schedule activities in accordance with the level of detail in a 3D model, and the level of detail in a project schedule. The modified project schedule is then used in conjunction with a 3D model to simulate the construction sequence in the form of a 4D animation. This allows for 4D visualization of project activities, installation dates, and crane movements. Furthermore, as engineering reaches completion, the PIM system creates a streamlined channel for schedule information updates to be easily uploaded into the model for a more accurate 4D visualization. Through analyzing a nonmodular construction case study, this paper discusses the successes and benefits of the PIM system for 4D visualization, such as increased productivity, shortened construction time, increased constructability, and decreased field costs.

Abstract

Scaffolds are temporary structures built to facilitate construction activities on site. A considerable amount of resources are allocated to scaffolding on industrial projects. Variability in geometrical features and space accessibility of structures on industrial projects, in addition to involvement of different trades that share the use of scaffolds, requires an extensive understanding of scaffolding requirements. Hence, it’s important to plan and estimate scaffolding man-hour requirements for the different construction areas on an industrial site. Contributing factors involved in such estimates include the list of trades that work in a construction area, trade working hours, volume of work, geometry of equipment erected, etc. A simulation template for predicting scaffold erection man-hour values for individual construction areas in an industrial project was developed in Simphony 4.0. The template is based on mapping the geometry of equipment and other factors to man-hours of scaffold work. The template facilitates the use of distributions as inputs and produces a range estimate of scaffold man-hours. The mapping is based on a linear regression model derived from existing project data from PCL Industrial Management Inc. The template is being further developed to incorporate the ability to predict scaffold erection schedule and material requirements based on construction work areas or equipment lists of an industrial construction project.

Abstract

In Alberta, Canada, heavy industrial projects are constructed using a prefabrication approach: spools and pipes are produced in the factory, and are assembled into modules that are transported to the industrial plants for installation by mobile cranes. Planning the onsite mobile crane operations is critical to the project budget and schedule. However, due to the large magnitude of industrial projects, manual heavy lift planning is tedious, and the results are not particularly responsive to site changes. This paper introduces an integrated mobile crane management system developed by PCL Industrial Management Inc., in collaboration with the University of Alberta, which investigates crane location selection and path checking for field module assembly. The project information is stored in a database, and the proposed system retrieves data, performs the calculations, and records the results back to the database; the calculations involve automatically selecting locations for the mobile crane, considering the crane capacity, lifting range and utilization. Lift paths for modules are checked for feasibility based on selected locations, satisfying the site and crane configuration constraints, and crane walking paths are planned if needed. The designed system is tested in an industrial project to validate the effectiveness of the system.

Abstract

Today, the deterioration of concrete structures due to reinforcement corrosion is a major problem in marine environments such as the Persian Gulf. chloride induced corrosion is the main reason for premature deterioration, and sometimes failure, of reinforced concrete structures constructed in this region [1, 2]. so, durability and serviceability of concrete structures in Persian Gulf region must be controlled. several studies had indicated that reducing the water to binder ratio and application of different pozzolanic materials are significant for developing durability and service life of concrete structures in harsh marine environment [3-6]. sf is an efficient pozzolan that increases the compressive strength of concrete by strengthening the transition zone and increasing the rate of hydration early in the life of the concrete [1, 7]. Neville [8] suggested a certain maximum content of 8–10% of cementitious materials for sf content in the Persian Gulf region. several studies have indicated that lowering the w/b ratio decreases the porosity, which thereby reduces chloride ingress during the exposure period and can improve the durability and permeability of concrete [9, 10].

Abstract

Intelligent computing tools such as artificial neural network (ANN) and fuzzy logic approaches are proven to be efficient, when applied individually to a variety of problems. Recently there has been a growing interest in combining both these approaches, and as a result, neuro-fuzzy computing techniques have evolved. This approach has been tested and evaluated in the field of signal processing and related areas. This paper presents the application of an adaptive neuro fuzzy inference system (ANFIS) to predict compressive strength behavior of ultra-high strength(UHSC) concrete specially Reactive Powder Concrete (RPC) considering mix design and curing conditions.

Citation: AminiKhafri, A., Taghaddos, H., Hermann, U., & AbouRizk, S. PRODUCTIVITY IMPROVEMENT FOR POSITIONING INDUSTRIAL MODULES USING GPS TECHNOLOGY AND SCHEDULING DATA.

 

Abstract:

Heavy industrial construction is primarily involved with construction of petrochemical or oil and gas related facilities. Due to cost and schedule savings, many industrial construction projects in Alberta, Canada are delivered using a modular construction approach. Modules are traditionally positioned using measuring tape, and coordinates are determined using construction site drawings. The practice of locating and positioning modules, however, is time consuming. Industrial construction projects are carried out in open fields, which is conducive to the use of GPS-based surveying equipment. Locating and positioning modules using a GPS-based approach, particularly one that incorporates automation, could result in considurable improvements to activity-level productivity. In this research study, an automation system, comprised of a GPS handheld device and an automated tool that calculates a module’s coordinates from available scheduling data and yard layout, is proposed. This system allows module positions to be automatically determined and precisely located. Implementation of the proposed automation system was estimated to improve productivity by over 500% and to reduce activity duration by two-thirds.

Citation: Taghaddos, H., & Dashti, M. S. SIMULATION-BASED CONSTRUCTABILITY ANALYSIS OF AN RCC DAM.

 

Abstract

Designing and planning construction operations is a challenging part of construction due to their highly complex dynamic nature. Simulation is a powerful approach, which has the ability to quantitatively, logically, and visually represent the construction process, its resources, and surrounding environment. Therefore, it can improve the design and plan of construction operations. This paper presents a simulation-based approach to model a major milestone of construction process of a roller compacted concrete (RCC) dam. Several what-if construction scenarios have been modeled for the milestone, based on different combinations of the resources. A time-cost trade-off analysis has been used to select the optimum construction scenario for the milestone. The results of the study demonstrate the capabilities of the simulation-based approach in designing and planning of RCC dam construction projects, based on a time cost-tradeoff framework.

Abstract

Some analytical investigations are done on the arrangement and orientation of fibers in steel fiber reinforced concrete (SFRC) specimens incorporating various volume fractions of fibers. The distribution functions of fiber location variables are investigated to produce an analytic model for the prediction of the mechanical properties of SFRC. Considering the effect of surrounding boundaries and distribution function, theoretical expressions are derived for the number of fibers per unit cross sectional area the orientation factor of fibers in SFRC. Finally, a comparison between empirical and analytical results are made to confirm the analytical results.

Citation: Kayhani, N., Taghaddos, H., & Noghabaee, M. (2019). Utilization of Virtual Reality Visualizations on Heavy Mobile Crane Planning for Modular Construction. arXiv preprint arXiv:1901.06248.

 

Abstract

Many kinds of industrial projects involve the use of prefabricated modules built offsite, and installation on-site using mobile cranes. Due to their costly operation and safety concerns, utilization of such heavy lift mobile cranes requires a precise heavy lift planning. Traditional heavy lift path planning methods on congested industrial job sites are ineffective, time-consuming and non-precise in many cases, whereas computer-based simulation models and visualization can be a substantial improving tool. This paper provides a Virtual Reality (VR) environment in which the user can experience lifting process in an immerse virtual environment. Providing such a VR model not only facilitates planning for critical lifts (e.g. modules, heavy vessels), but also it provides a training environment to enhance safe climate prior to the actual lift. The developed VR model is implemented successfully on an actual construction site of a petrochemical plant on a modular basis in which heavy lift mobile cranes are employed.
