Under the actual development scenarios, attention to competences of programme managers and project managers related to public transportation infrastructure projects has risen substantially. An inefficient bureaucratic system is related with deficiencies of people skills and competences. On the other hand, an excellent system demands quality of the system and quality of people working in it. Thus, it is important to have excellence in administration and excellent administrators in the public sector. Three main lacking elements have been identified: i) lack of good education; ii) absence of fair salaries in the public sector; and iii) lack of incentives. Many misconceptions and disputed consequences have been observed and analyzed. It is clear that there is lack of competence among infrastructure transport project managers and teams, which causes trouble with the main goal of Peru getting benefits from these investments and achieving sustainable development. Furthermore, the right way to achieve these benefits is through a new model of education for project managers and programme managers in Perú. This education should be based more on competences than on qualifications. Thus, the International Project Management Association (IPMA) competence baseline, which is the standard that best fits to these needs, needs to be implemented to achieve the real contribution and benefits of these projects to society.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"9 1","pages":"1537 - 1546"},"PeriodicalIF":2.1,"publicationDate":"2017-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42428981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The records related to the quantities were collected from consultancy firms that provide reinforced concrete design services. The data were collected for residential buildings up to four floors. Linear regression analysis was chosen to show the correlation between the included variables. The following variables were used in the regression models: quantity of reinforcement steel (dependent variable), structural element volume (independent variable) and floor area (independent variable). Fourteen models were developed; nine models were developed to compute the quantity of reinforcement steel in different structural elements: slabs, beams, columns and footings. The other five models were used to estimate the total steel quantity in a residential building. The coefficient of multiple determination (R2) of the developed models ranged from 0.70 to 0.82. This confirms a good correlation between the dependent and the independent variables. The accuracy of the developed models was tested using the mean absolute percentage error (MAPE) test. With MAPE values ranging from 21% to 36%, the results compare favourably with past research that indicated that accuracy between ±25% and ±50% at the early stages is acceptable. The results also show that the models built on structural element size have better accuracy than the models using floor area. Such types of equations are very useful, especially in their simplicity and ability to be handled by calculators or simple computer programmes.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1405-1410"},"PeriodicalIF":2.1,"publicationDate":"2016-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/OTMCJ-2016-0006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67252143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their importance for business success is undisputed, as bankruptcies due to insufficient cash flow underline. Therefore, this study investigated current business practices of electrical contracting companies of different sizes with respect to their financial planning and management. A detailed questionnaire was developed with best guidelines on survey studies and pilot testing. It was sent to members of the National Electrical Contractors Association. Respondent anonymity was ensured. The survey recorded demographics, business practices, operating conditions, and other important factors using 57 subquestions. Each section allowed feedback to clarify the numerical responses. Responses were well distributed across company sizes, so that the results are representative for the entire industry. The results indicated that contractors generally have a substantial amount of experience in financial decision making. Their approach is conservative and focuses on healthy growth. Yet, opportunities to fine-tune business practices are identified, e.g., immediate invoicing, considering discounts to accelerate payment receipts, attempting to negotiate and use favorable credit terms, reviewing payment performance, and performing frequent cash flow forecasts. Some of the differences in the responses can be attributed to different company sizes. To help especially smaller companies in planning their cash flow, a spreadsheet for implementation has been created.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1482-1498"},"PeriodicalIF":2.1,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/OTMCJ-2016-0011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67252704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process has posted a lot of challenges to construction stakeholders; it is therefore, necessary to examine the relationship between bond administration and project success. Archival data of completed bonded building projects were gathered through a pro forma developed for this purpose. Using Pearson product moment of correlation, it was revealed that the cost of securing a construction bond has a positive and significant effect on the initial and final costs of the project, while the number of days needed to secure a construction bond has no significant effect on the initial and final durations of the construction project. In order to establish the relationship between project delivery indices of cost and time and the construction bond administration variables, iteration of linear regression was adopted to arrive at the best-fit equation. Factors affecting the cost of securing construction bonds from guarantors should be identified and given adequate attention by construction stakeholders in order to minimize the effect of construction bond administration on project delivery.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1390 - 1396"},"PeriodicalIF":2.1,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/otmcj-2016-0001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67251808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, the pavement condition was evaluated in terms of the surface distresses existing at the time of the field evaluation. The PCI procedure was used in this research because it deals with the subject of pavement distress identification most comprehensively and is based on a sound statistical technique of pavement sampling. Because of limited maintenance fund availability in Yemen, timely and rational determination of M-and-R needs and priorities are very important factors. The PAVER™ (1982) condition rating procedure, as described in the Technical Manual TM 5-623, Pavement Maintenance Management, which is based on the PCI, was used in this study to evaluate a major heavy-traffic road corridor connecting Aden city (the commercial capital of Yemen) with major cities located in the northern region of the country. Based on the PCI of the road sections, the necessary maintenance or rehabilitation procedure is suggested.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1446 - 1455"},"PeriodicalIF":2.1,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/otmcj-2016-0008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67252649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of this research is to regulate this role when in a project and to define and develop a building agent structure, according to the Building Standards Act (LOE by its acronym in Spanish), to be able to incorporate it into the Spanish law, protecting it from civil liabilities. In Spain, there is jurisprudence in civil jurisdiction based on the LOE to acquit or convict building agents, who are defined in the courts as “constructive managers” or similar. For this reason, courts could establish in the future several liabilities for the lean construction specialist and other agents of the project, depending on their actions and based on the implementation of the lean project delivery system, the target value design and the integrated project delivery. Conversely, it is possible that the level of action of the lean construction specialist may comprise design management, construction management and contract management. Accordingly, one or more building agents should be appropriately incorporated into the LOE according to their functions and responsibilities and based on the levels of action of the lean construction specialist. The creation of the following agents is proposed: design manager, construction manager and contract manager, definitions that are developed in this study. These agents are loosely defined, because any project manager, building information modeling manager or similar may act as one or as more-than-one of them. Finally, the creation of the lean construction manager is also proposed, as the agent who takes on the role of the design manager, construction manager and contract manager, but focused on the lean production principles.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1511 - 1517"},"PeriodicalIF":2.1,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67252700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although, in recent decades, many changes have occurred in the construction industry, there are still many problems in this area. Therefore, research in this area becomes vital because collaboration is one of the best approaches to improve CSC performance. In this study, collaborative relationship has been found to be affected by three main factors: managerial, financial and structural. However, application of collaboration in Iran is still in its inception. This comprehensive research study focuses on suitable context for implementing the collaboration method. The methodology of this research is based on interviews and a review of previous research, which identifies critical factors and positive results of use in relation to collaboration. Results of this study improve our knowledge about the role of collaboration in a CSC's performance. Analysis of data shows that managerial factors have the most positive effects on the implementation of collaboration networks in CSCs, followed by financial factors and organizational factors.","PeriodicalId":42309,"journal":{"name":"Organization Technology and Management in Construction","volume":"8 1","pages":"1437 - 1445"},"PeriodicalIF":2.1,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67252263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
