Abstract Investor bears responsibility for proper preparation of the investment process. One of his tasks is to prepare the project documentation and obtaina building permit. Frequently, during his work, there are situations and events whose im pact interferes with the design solutions. Regardless of reasons, alterations to a project constitute a source of cost risk. In each case, the Investor should be prepared for this type of a risk. Exposure to risk should be taken into account in the planning stage of the investment. Also, a model of investment execution should be chosen at this stage. The type of model is associated with the distribution of risk throughout the project. The aim of this paper is to identify events that generate risk related to alterations to Project Documentation in the context of the selection of the investment executionmodel.

The article presents a settlement analysis of introduced changes in the example infrastructure investment. The procedure of introduced the Change Command and the Engineer's Instruction on the Construction contract, as well as examples of the Change Commands given by the Engineer on the analyzed object were presented. The study covered the settlement of a road investment, based on compliance with expressway parameters. The analyzed object was very composed, thus has an extended bill of quantities and cost estimate. In accordance to such an extended cost estimate for this investment, it was important to establish an appropriate and fast flow of settlement documents. Moreover, changes in the project documentation and settlement based on the Contract Conditions for the Construction for Engineering - Construction Works designed by the Employer - the so-called. & quot;Red Book& quot; was showed. The studies discussed the cases of settlement of increased quantities, new entry items and replacement construction works that occurred on the analyzed investment, as well as examples of a sample settlement documents. The authors of this studies conclude that the introduction of the Engineer in the early stages of the investment process and the overall FIDIC procedures help establish sample forms, development of working out procedures and document flow schemes, including a settlement documents. In consequence they minimize the costs of addition, replacement, and abandoned works and reduce the time of the investment realization.

Abstract One of the most important documents occurring in the investment process is the administrative decision: building permit. Obtaining it is often a time-consuming process in practice, associated with the need to attach to the application other required decisions and permits necessary for a positive consideration of the case. The procedure itself is not always a long-term process, as long as the investor makes sure to prepare a reliable application free of errors and irregularities together with the construction project and the required attachments. The purpose of the article is to analyze errors appearing in investors’ applications and attached project documentation required in the administrative procedure for obtaining a building permit in the light of the applicable provisions of Polish law.

Selection of a most optimal project alternative in early phases of project development is paramount for overall project success. A standard practice is to make the selection based on economic considerations that overlook risk exposure of a selected alternative. Standalone risk evaluation of alternatives cannot ensure that a most optimal alternative is selected either as economic considerations may be overlooked. Moreover, both economic-based and risk-based alternative's selection methodologies cannot guaranty that all viable alternatives have been considered. This chapter introduces integrated risk-based and economic-based (IRBEB) alternative's selection methodology that includes an algorithm to generate a comprehensive set of all viable project alternatives to choose from.

This paper consists of the application considerations given for the selection of on-site power generation using a gas turbine with a recovery boiler in the process chemical industry. The additional use of 400 psig steam from recovery heat of the gas turbine exhaust used for process steam is evaluated. The techniques used for engineering, construction, training, and start-up are discussed. The performance of the unit after 30,000 operating hours, including reliability and a discussion of equipment problems, is included.

The article presents the results of nationwide surveys on the causes of delays during the implementation of rail investments in Poland, carried out in the Design & Build formula for the design stage. The study did not examine typical causes of threats to general construction works, only those that result from the specifics of works at rail facilities. The survey was conducted with the participation of experts from various industries, representing all the key participants in the investment process. The selection of experts was limited to people who have extensive professional experience in implementing rail projects. Statistical analyzes were performed using the IBM SPSS Statistics 23 package. It was used to test χ2 and a one-way repeated measures ANOVA. The greatest threats to the deadlines for the implementation of rail investments in Poland, which were indicated by the respondents as the delay threats of a high importance are: negligence in the preparation of tender documents and problems with obtaining current maps for project purposes from rail geodesic centers. The research results can be helpful when planning future rail investments, calculating the necessary time reserves and increasing the reliability of the set dates of their completion.

AbstractObjective:To review and categorize the problems associated with undertaking physical activity validation studies and to construct a checklist against which any study could be compared.Results:The studies reviewed demonstrated problems in defining the dimension of physical activity that is of interest and in the selection of an appropriate comparison technique. Ideally this should be closely related to the true exposure of interest and assess that exposure objectively and without correlated error from the study instrument in question. In many studies inappropriate comparison methods have been chosen which do not measure the true underlying exposure and which are likely to have correlated error. The choice of study populations, the frame of reference of the exposure measurement and the use of appropriate statistical methods are also problematic areas.Conclusions:There is no ideal measurement instrument or validation study design that is suitable for all situations. However, the checklist in this paper provides a means whereby the appropriateness of studies already undertaken or at the planning stage can be assessed.

Engineering geological maps are essential background data to the planning of land use, and design, construction, and maintenance of civil engineering works. They contain important information on ground conditions for the safe engineering construction. This paper provides three examples of the advantages of engineering geological mapping during the planning stage of the projects. The maps provided the preliminary information to engineers who were then able to make decisions regarding further investigation and feasibility of the projects. The paper further highlights the importance of executing a thorough engineering geological mapping before the commencement of a project.

A medical centre is one of the most complex building types to design because it requires complete understanding of work organisation and the disabilities faced by patients. Based on personal observations and the literature, selected ophthalmic centres around the world were analysed, with a focus on design solutions that improve their functionality. Instituto de Microcirurgia Ocular is characterised by a very well-thought-out arrangement of rooms. The Harkness Eye Institute is an excellent example of the modernisation of an almost century-old building. During the design of the Richard Desmond Children’s Eye Centre, inspiration was sought in the medical world, creating an interior that was extremely child-friendly.
