Delays in the Iranian construction projects: Stakeholders and economy
E. Asnaashari, A. Knight & A. Hurst
Nottingham Trent University, Nottingham, United Kingdom

ABSTRACT: The construction industry has a major role in the Iranian economy by generating employment and wealth. However, delay is one of the most reoccurring problems in the Iranian construction industry and has negative impacts on project success in terms of time, cost, and quality. This paper presents one part of an investigation into the factors which cause delay in construction projects in Iran. In that study, eleven in-depth interviews were carried out with Iranian construction practitioners. Qualitative analysis of responses categorized causes of delay in five groups as: (1) Stakeholders; (2) Economy; (3) Politic; (4) Management; (5) Miscellaneous.
This paper, by focusing on the two first groups, develops a comprehensive interpretation to reveal the role of stakeholders and economy in causing delay in construction projects in Iran.

INTRODUCTION

Project scheduling is the first challenge at the inception of most construction projects. Without a systematic planning and scheduling, managing construction projects is hardly possible.

However, projects’ schedules often are affected by several factors which can endanger the success of the project. One of the most important factors that seriously affect projects’ schedule is delay.
Delay is ‘the time overrun either beyond completion date specified in a contract, or beyond the date that the parties agreed upon for delivery of a project’ (Assaf
& Al-Hejji 2006). Delay is also defined as an ‘act or event which extends

    branch is taken or not. In the MIPS CPU, the branch operation is delayed by one instruction. The MAL assembler hides the delayed branch by inserting an instruction after each branch or jump. The instruction following a branch or jump is called the delay slot. By default the assembler inserts an instruction which does nothing, a no-op. In previous sections describing the branch instruction, it was stated that the PC was incremented when the branch was fetched and therefore the branch offset is relative…

For example, if the normal range for learning to walk is between 9 and 15 months, and a 20-month-old child has still not begun walking, this would be considered a developmental delay. Developmental delays can occur in all five areas of development or may just happen in one or more of those areas. Also the…
