TL;DR: In this article, a questionnaire survey was undertaken of project managers working on high-rise construction projects in two Indonesian cities: Jakarta and Yogyakarta, and the results reflect construction management problems common to developing countries.
Abstract: Many variables have an impact upon construction time and cost overruns in Indonesia. A questionnaire survey was undertaken of project managers working on high-rise construction projects in two Indonesian cities: Jakarta and Yogyakarta. The variables identified were ranked according to their perceived importance and frequencies of occurrence. Inflationary increases in material cost, inaccurate material estimating and project complexity are the main causes of cost overruns. The predominant causes of delay are design changes, poor labour productivity and inadequate planning. Using factor analysis techniques, delay and cost overrun variables were grouped into factors, and their relationships analysed. Although Indonesia specific, the results reflect construction management problems common to developing countries.

TL;DR: In this paper, a survey was conducted to establish the relative importance of the attributes of clients' organizations which may influence project consultants' performance using the "relative index ranking technique" and the most important attributes were financial stability of client, current liabilities and current assets, feasibility of the project (project priorities, feasibility study and site conditions), past performance of client (cost etc.).
Abstract: Despite numerous efforts to understand construction clients and their priorities, evidence abounds to suggest that they are largely misunderstood and dissatisfied with the performance of their consultants and contractors. The perception of poor performance may not be attributed to the consultants alone. Perhaps the clients themselves do not possess the necessary attributes to secure a successful project performance. This paper describes a survey which set out to establish the relative importance of the attributes of clients' organizations which may influence project consultants' performance using the ‘relative index ranking technique’. Project consultants were surveyed using a structured questionnaire as the main research tool and this was augmented by interviews. The most important attributes are financial stability of client (creditworthiness, current liabilities and current assets), feasibility of the project (project priorities, feasibility study and site conditions), past performance of client (cost ...

TL;DR: In this article, the United Kingdom tendering procedure should embrace investigation of contractors' potential to deliver a service of acceptable standard, on time, within budget, and significant weaknesses are identified, confirming the need for some revision of existing contractor selection methods.

TL;DR: In this paper, the authors discuss different delay analysis techniques that are currently used by practitioners in the construction industry and propose a new delay analysis technique called the isolated delay type (IDT).
Abstract: Construction projects continue to suffer delays. Things go wrong and the project's completion date gets pushed back, with someone to be blamed for it. In practice, attempts are made to identify the causes of delays and schedules are modified to incorporate revised duration and new project time. The analysis itself is usually complex and can be aided by a computerized approach. This paper discusses different delay analysis techniques that are currently used by practitioners in the construction industry. It also discusses a proposed new delay analysis technique called the Isolated Delay Type (IDT). These techniques were tested against a case example and their strengths and weaknesses highlighted. The new technique can be used as a standalone module for delay analysis or could be incorporated within a computer system for construction delay analysis and claims preparation called Computerized Delay Claims Analysis (CDCA) that integrates different software including an expert system and management software such...

TL;DR: In this article, the authors investigated the problems influencing craftworkers' productivity on 27 medium and high-rise building sites surveyed in Indonesia and identified five specific productivity problems, i.e., lack of materials, rework, absenteeism, lack of equipment and tools and gang interference.

TL;DR: In this article, a survey on time performance of different types of construction projects in Saudi Arabia was conducted to determine the causes of delay and their importance according to each of the project participants, i.e., the owner, consultant and the contractor.

TL;DR: The TFV-teoriaksi (Transformation, flow, value generation) as discussed by the authors is a well-known method for value generation in the literature, e.g. in finance.
Abstract: Vaitoskirja pyrkii vastaamaan kahteen kysymykseen: Onko mahdollista muotoilla tuotannon teoriaa? Jos on, johtaako teoria tehokkuuden kohoamiseen, kun sita sovelletaan rakentamiseen?
Historiallinen analyysi paljastaa, etta 1900-luvulla on kehitetty ja sovellettu kolmea eri tuotannon kasitteellista mallia. Tuotanto on nahty muunnoksena, virtana ja arvontuottona. Kaikkia naita malleja voidaan perustellusti pitaa valttamattomina tuotannon ymmartamiseksi, ja niita tulisi siten soveltaa rinnakkain. Vaitostutkimuksessa esitettavaa tuotannon mallia kutsutaan tuotannon TFV-teoriaksi (Transformation, Flow, Value generation).
Tutkimuksen tulokset osoittavat, etta tehokkuutta alentavia ongelmia esiintyy yleisesti rakentamisen kaikissa vaiheissa: rakennuttajan paatoksenteossa, suunnittelun ohjauksessa ja rakennustuotannon ohjauksessa. TFV-teoria selittaa suurelta osin rakentamisen ongelmien syntymisen. Tarkasteltaessa pioneeriyritysten kehittamishankkeita, joissa on sovellettu TFV-teorian tiettyja ydinpiirteita, voidaan havaita, etta talle teorialle perustuvat menetelmat tuottavat merkittavia kustannussaastoja ja muita hyotyja. TFV-teorian avulla voidaan siten suunnata uusiin tehokkaampiin menetelmiin tahtaavaa kokeilua ja kehitystyota seka rakentamisen kaytannon etta tutkimuksen piirissa.

TL;DR: In this paper, the authors present the results of a survey undertaken to determine and evaluate the relative importance of the significant factors causing delays in Hong Kong construction projects, including poor site management and supervision, unforeseen ground conditions, low speed of decision making involving all project teams, client-initiated variations and necessary variations of works.
