IRJET - Delay Analysis of a Construction Project- A Case Study
0 likes•65 views
This document analyzes delays in a 14-villa construction project in Bengaluru, India called Nature Walk. It found that the project was delayed 66 days beyond the original schedule. Critical activities that faced delays included foundation work, floor slab casting, block work, plastering, and painting. The delays were caused by factors like rain, labor shortages, materials shortages, and payment issues. As a result, the project cost Rs. 620200 more than planned. The analysis aims to identify causes of construction delays so owners can minimize risks of cost overruns and schedule delays on future projects.

3. CONCLUSIONS
On analyzing it’s been found there is a delay of 66 days in
the completion of the project. The critical activities of the
project are foundation, casting the floor slab, block work,
external plastering, painting and doors. Inspire of critical
activities, there are some additional activities where the
project experienced difficulties in execution and delay in
completion.
From the delay analysis an amount of Rs. 620200/- has
been incurred to the project which is an additional loss to
the project and simultaneously over shoots the budget
allocated to the project. The main causes of the delay in
the project are both excusable and non-excusable delays,
which are identified by the occurrence and experience.
The main delays were recorded and the loss of
productivity and cost loss has been calculated.
In this study, the main causes of the delay occurrence are
rain, unskilled labors, shortage of skilled labor, poor
workmanship, shortage of labors, inadequate of
availability of materials, non-availability of materials,
delay in payment to the contractor by client, partial
payments to labor by contractors. These delays imply that
contract related delays require adequate attention,
because these delays topped with huge loss to the
company and project duration overrun. Time overrun and
cost overrun effects are more in this project. So, necessary
action should be adopted to avoid the delays which lead to
project loss.

A proper construction planning and schedule acts as a main role ford different purposes. By using the schedule, we can know the merely completion of the project, contractors can recruit the necessary manpower; can demand shifts or equipments to speed up the project. The most important function of the project management is to plan and control the project objective like time, budget and setting out of resource productivity standards to achieve the objectives of the project. Delay happens in all construction projects. Where construction project will vary in size, some will be in small. In vast projects, analysis should be done for the purpose on making right decisions on time and cost compensation claims. Many type of software’s are available to plan, execute and control the project; with the help of these software’s the project management has become easier to evolve the construction project. Large quantities of different kind of resources are required for execution and the risk is more in case of big projects. So, planning and scheduling in big projects is essential. In this study, an effort is made in planning, scheduling and delay analysis and updating of various activities which is done using MS project. Key Words: Construction Management, Planning, Delay, Labour Productivity, Scheduling, Tracking. 1. INTRODUCTION Construction industry plays an important role in the economic growth of a country. It is the process of implementing the plans, ideas, standards, specifications and assigning the resources into a physical facility to meet the specific requirements of owner. Construction management can be defined as the accomplishment of results through the combined effort of the consultant, client and designer. Construction is a very unique and creative practice which coverts four M’s of the construction-Material, Manpower, Machinery and Money into a systematic structure. Thus construction management contains Planning, Executing and monitoring the construction activities in a specific project. 1.1 Project Planning, Scheduling and Controlling The main aim of the construction management is to plan and schedule the resources within the frame work of a project. The guidelines and procedures of the construction management direct the managers how to utilize the resources during the construction process. Before execution of the work on the site all kinds of office works such as planning, designing, estimating, negotiating, purchasing, scheduling, controlling etc. should be done carefully. 1.2 Construction Delay Analysis Delay is one of the common problems in the construction project. Delay of a construction project is defined as late completion of the project as compared to the planned schedule. Construction delays are often resulting of miscommunication between contractors, subcontractors, owners and suppliers. These types of unrealistic exceptions are usually avoided by clean and efficient planning mechanism, which clearly specifies the work and timetable to be used. Delays in construction project are quite expensive; sometimes they may result in severe damages to the involved parties. 1.3 Objective of the Study Detailed literature study to define the various causes of delay in construction projects Study on ongoing Project site to observe the activities and to identify delay factors Determination of Critical Path using MS Projects The analysis also involves the process of scheduling and tracking of a construction project activities in software and related catch up programs due to delays. 2. METHODOLOGY Site Investigation. Studying Of BOQ & Drawings. Study On Labor Productivity. Scheduling. Tracking & updating of project. Delay Analysis. Results & conclusions. 2.1 Brief Details of Project Nature Walk is a Villa project consisting of 14 Villas of 3BHK and 4 BHK.
