AbstractRequest for information (RFI) is a formal process used in the Architecture, Engineering and Construction industry to address design flaws that affect communication between designers and contractors. A large number of RFIs are a sign of a lack of precision or coordination in the design documents. However, RFIs produce rich, precise, and structured information. Analyzing their content can help to identify recurring problems between designers and construction teams and better tailor future projects to the working context of the contractors. This article presents a method for identifying recurring issues during the design phase of steel construction projects through the analysis of the contents of RFIs. It is original in using a qualitative content analysis tool that can analyze large quantities of RFIs rapidly. Identifying the recurrent problems of contractors will allow the establishment of rules to be taken into consideration during the design phase of future steel construction projects. A case study of 26 steel construction projects demonstrates the feasibility of this method. This case study shows that, given the same designers and construction teams, recurring problems shown in RFIs do not differ according to the scale of the projects. In this case, the main issue between designers and contractors is the lack and inadequate presentation of information related to the connection of steel components. Identifying these problems can pave the way for initiatives to improve the design phase and can be an essential step in making contractors’ knowledge available to designers early in the projects.

Rate Calculation

The purpose of the paper is to identify factor space influencing on the value of discount rate in the assessment of effectiveness of investment and construction projects. As a result of investigation, a general classification of investment and construction risks was drawn up, depending on influence of external and internal environment of the enterprise. The factor space, which is used for initial data of separate investment and construction projects, was identified. A general algorithm of risk assessment of investment and construction project is developed, taking into account the reasoned justification of the method used for discount rate calculation, with the possible application of the variable discount rate at different stages of project’s life cycle.

The implementation of railway infrastructure construction projects including sustainable development goals is a complex process characterized by a significant extension of individual investment stages. The need for additional works has a big impact on construction railway projects, representing a risk which is the result of many different factors. During the execution of works, both the design assumptions and the conditions of the project’s implementation can be changed. An attempt to eliminate potential risks is a key element of construction projects. The article proposes a proprietary management method for the risk of additional works in railway projects. A methodology for creating risk management strategies using a standard algorithm that includes risk identification, risk analysis, and risk assessment is presented. The original elements of the work include risk identification followed by analysis using Bayesian networks. Using the example of a scenario of events, it is shown that a well-programmed network can be used to implement risk mitigation methods. Using the network, it is possible to compare different ways to reduce risk, check the effect of reducing the risk factors, and determine a satisfactory level of effects, e.g., increased financial resources as a result of additional works.

Design Schedule

Korean oil and gas contractors have recently incurred significant losses due to improper engineering performance on EPC (engineering procurement and construction) projects in overseas markets. Several previous studies have verified the significant impact engineering has on EPC construction cost and project lifecycle. However, no literature has studied the time impact engineering has on EPC projects, representing a gap in the existing body of knowledge. To fill this gap, a Monte Carlo simulation was performed with the Pertmaster, Primavera risk analysis software for three sample onshore oil and gas projects. From said simulation of all major EPC critical activities, the authors found that the engineering phase is up to 10 times as impactful as the procurement and construction phases on the overall schedule duration. In assessing the engineering activities, the authors found the piping design activities to have the greatest impact on the overall schedule performance. Using these findings, the authors present a design schedule management process which minimizes the delays of project completion in EPC projects. Said process includes the following six steps: (1) Milestone management, (2) drawing status management, (3) productivity management of engineering, (4) interface management, (5) management of major vendor documents, and (6) work front management. The findings of this paper add to the body of knowledge by confirming the design phase to be the most impactful on the overall project schedule success. Furthermore, the presented design schedule management will aid industry with successfully executing the design phase in a timely manner, including examples from case study projects for a greater understanding.
