2.12.9 Construction Delay: Quantitative Analysis

In some studied already done in issue with comstruction management, one of the main objectives of (Al-Momani, 2000) was to figure out the cause and degree of interruptions in public projects in Iran. Some of these studies investigated the causes of these interruptions for about 130 projects, counting office and communication facilities administration buildings residential buildings, schools, medical and centers. The sample population was recognized by choosing 130 ended public projects in diverse areas of Iran among the years of 1990 and 1997. To examine why construction delays and issues occurred, the succeeding statistics were gained from the projects' records:

ae Planned period of contract ae Actual conclusion statistics

ae Design variations

ae Disagreements

ae Warnings

ae Date of notice to continue ae Delays come across throughout construction ae Conflicts connected to the drawings and stipulations ae Time postponements ae Late delivery of material and equipment

As shown in Table 3.4, the incidences for each limit in five dissimilar construction groups were delivered, and numerous projects were behind for numerous reasons. The study establish that the chief causes of postponement were deprived design, change orders, weather, site circumstances, late distribution, financial conditions, and upsurge in quantities. The main reasons of delay discovered in this study were poor design, change order and site and financial situations.

2.13.10 Construction Delay: Developing Economy

(Ogunlan et al. 1996) displayed a certain survey which was able to look at the issues in construction management that were experienced while in the process of constructing high-rise buildings in Iran. Twelve projects were chosen for examination and meetings were presented with their main engineers. Interviews took place right there on the project sites, and a total 20 persons had been questioned, on behalf of 2.4 individuals per project. Candidates were allowable to effortlessly debate the details for their development's breaks and categorize the parties that were complicated. The facts of the origins of interruption can be seen in Table .

3.1 Poor ICT groundwork

If a construction site does not have an extensive and high quality ICT groundwork, it's not likely to exploit ICT power entirely.

Some defendants consider that Iran's ICT infrastructure does not really permit them use their ICT devices with the entire volume. For instance internet speed is not really enough to be able have an online meeting by video conference, on the other hand, they could maybe be ready to have some kind video conference if the internet speed is a whole lot better. Furthermore, in some distant construction locations which are out of city parts, there is not much contact to internet. As a result, some innovator construction businesses in ICT who have enormous developments in distant regions, have to capitalize on ICT groundwork merely for that project and this substance forces an excess cost to them. One of the defendants specified "as a group we are driving on the ICT road. it's not conceivable to even drive fast on a road that is stony. If we have made the decision decided to go that route this way, the road should be paved."

3.2 Unacquaintedness of local personnel with ICT in remote construction sites

The staffs who are employed in construction sites are typically in lower level of field associated with office workers and this matter is simple for distant construction sites for the reason that discovering local experts is not continuously conceivable. As a result, the company have to give more to send specialists to distant construction sites. This subject is not cost functioning for small developments for the reason that a small project typically has a small income boundary and it is not defensible to capitalize a lot for sending accomplished personnel to distant construction places for a small profit.

3.3 No financial justification for ICT training of personnel in small construction sites

Accomplished personnel are money for a company. The construction firms are the ones that usually make the attempt to upkeep their ones that are educated and experienced staff. As it was articulated, expert local workers are not typically obtainable to service in remote. construction locations. Teaching the local personnel is an answer merely for huge construction projects, for the reason that the local trained personnel of small developments will be jobless in that district after project conclusion and typically the gotten profit is less than cost of education.

3.4 Lack of sensation transfer in some electronic communication devices

It is clear that individuals really do show their goals with words. The words are marked otherwise in different circumstances. Each articulation comprises a precise feeling and resolution. One of the hindrances of electronic communication devices is that is really does show some sort of lack of feeling transfer. Video session is a communique instrument that is very helpful for those construction firms that are performing remote construction developments. Online meeting can decrease travelling price of personnel among head office and construction place. On the other hand, one of the respondents spoke that their corporation has the wanted ability for video conference, nonetheless the personnel don't really welcome these ICT devices. He made the point that it has a human motive. He mentioned "When the individuals are together, have more truthful sentiment about having a meeting than when they are in their own house. They have more reaction and action and meddling when they are composed."

3.5 Inapplicable software outputs

Engineering judgement has been a major issue when it comes to design procedure of every construction development. In the design stage it is really essential that knowledgeable and well-informed engineers strategy or supervise the design procedure. Their knowledge allows them to have an outstanding engineering judgement about applicability of design software productions. One of the software designers trusts that even if he deliberate structuring codes in their software as much as he can, on the other hand if the user had not adequate technical information, he/she cannot use the software properly.

It can be concluded that in the remote construction developments that designers are doing in main office and away from construction location, applicability of software productions will be reduced if the designers did not have sufficient experience and resourcefulness from implementation of the productions and if they want to visit and oversee the construction site, it will cost a lot to exchange among head office and construction location......
