Top 5 Reasons of Delays and Disputes in Infrastructure Projects in India

Top 5 Reasons of Delays and Disputes in Infrastructure Projects in India

With the present emphasis on creating physical infrastructure, massive investment is planned in the infrastructure sector in India. However, infrastructure projects in India are infamous for Delays and Disputes. As a result, there is significant time and cost overruns in projects. Projects across different government employers suffer from 50-100% cost overrun, primarily due to Delays.

Several studies and surveys are conducted to investigate reasons and their relative impact on these delays and disputes. With our extensive experience in project and claims management, we grouped several overlapping factors into 10 primary reasons and then analysed their relative contribution to Delays and Disputes. The result of the analysis is presented as below:

Delay in handing over Right of Way/Site
Poor Scope and Interface Management by Owner/Engineer
Delay in Payments by Owner/Engineer
Slow Decision Making by Owner/Engineer
Incorrect Contracting Practices by Owner/Engineer

1. Delay in handling over Right of Way/Site:

It is not surprising to find that Top reason is the Delay in handing over the Right of Way / Site to the contractor due to unpredictable and lengthy land acquisition process coupled with politically motivated agitations and equally lengthy inter-departmental permission processes in India.

2. Poor Scope and Interface Management by Owner/Engineer:

The second most frequent reason for delays and disputes is the unavailability of work fronts due to poor interface management among various agencies and contractors involved in the project. Although it is noted that generally, scope breakdown (work packaging) is based on only size manageability without precise scope distribution and interface matrix (RACI) and Master Implementation Program, it results in many scopes omission/duplication and too many interfaces, which in turn results in many scope addition/deletions during construction.

3. Delay in Payments by Owner/Engineer:

The third most frequent reason for delays and disputes in infrastructure projects is delayed payment to contractors. Again, several legitimate reasons range from fund allocation blues for Govt. funded projects to poor payment terms in the agreed contract.

4. Slow Decision Making by Owner/Engineer:

One of the most common reasons for delays across the sectors and industries as experienced by us in performing delay analyses is the excessive time taken by the owner / Engineer in review and approvals of technical and non-technical deliverables multiplied with too many rounds of commenting and revisions. There are instances where a critical design document approval process has taken >1000 days! Unbelievable but true!!

There are many reasons for slow decision making. Still, the most contributing reason found in our analyses is (a) lack of collaboration among various disciplines, departments with bureaucratic structure and multiple agencies, both internal & external working in silos and (b) non-availability of timely and correct information for effective decision making. Therefore, a Smart Engineering Document Management System Integrated with Project Communication and Interface Management Systems is an absolute necessity for successful project delivery.

5. Incorrect Contracting Practices by Owner/Engineer:

The top contract-related reason that creates frequent disruptions during execution is poorly written and incomplete, and heavily one-sided contract. It leads to cascading delays due to the stoppage of work or pace slowdowns. Our analyses have found several reasons out of which most frequent ones are:

Lack of staff experience for contract management and adoption of the wrong contract standards leads to poorly written and incomplete documents. We often receive a tender document for consulting services amended from a standard tender for construction works. We find that it has many clauses that are not applicable for consulting work and at the same time, it does not have many mandatory clauses applicable to consulting services.
Unreasonable Contracting Risk perceptions lead to a heavily one-sided contract document.

Tendency to transfer all the risks to the contractor
Tendency to pass on interfacing responsibility on the contractor
Tendency to cover up all unknowns within the scope of the contract

“Simply passing risks and complexities on to the contractors does not actually mitigate them. Ultimately, it only affects outcome of the Owner’s Project adversely”

Protecton BTG has been instrumental in setting up these systems at India’s first bullet train project MAHSR and is currently in active discussion with other important infrastructural projects for providing MIP services and implementation/operations of SMART PMS.

NCRTC begins assembling of Special Spans for challenging sections of the RRTS corridor

NEW DELHI, INDIA (Metro Rail News): NCRTC is implementing India’s first RRTS corridor that connects Delhi with regional nodes of Ghaziabad, Murad Nagar, Modi Nagar, and Meerut. In this 82 km long RRTS corridor, a total of 70 km stretch is elevated, and 12 km stretch is underground. Most of the elevated stretch of the Delhi-Ghaziabad-Meerut RRTS corridor is passing through the median of Delhi Meerut road (erstwhile NH-58) and densely populated areas which have heavy traffic movement as well.

To construct the elevated viaduct of the RRTS corridor, NCRTC is erecting piers generally at an average distance of 34 meters (approximately). Post this, these piers are being joined by pre-cast segments with the help of launching gantries to construct an RRTS viaduct span. However, maintaining this distance between piers is not practically possible in some complex areas where the corridor is set to cross over rivers, bridges, rail crossings, metro corridors, expressways, or other such existing public infrastructure. Also, the maximum length of standard spans used to connect these piers is approximately 37 meters.

To connect piers in such areas & congested zones, Special Spans are being used. Special Spans are mammoth civil structures having beams made of structural steel. NCRTC is building Special Spans made of structural steel at a factory which is then transported to the sites on trailers during the night to avoid any bunch up of traffic and assembled in a systematic way with help of specialized cranes. The size and structure of these steel spans are designed aesthetically in advance, in line with the overall requirements of construction, installation, and usage.

NCRTC is establishing two such Special Spans, between Sahibabad to Ghaziabad, with customized shape, elevation, design, and weight. One of the spans is being set up at Vasundhara, which is 73 meters long and weighs 850 tonnes, to cross the railway crossing. NCRTC is taking all measures to ensure the services of Indian Railways running below is not affected and the construction work is completed on time diligently.

Another mammoth span is being set up for Ghaziabad RRTS station, the highest station of the RRTS corridor, crossing over the Red Line of Delhi Metro and the road overbridge. Portal Piers have been erected for the installation of Special Span on either side of the metro viaduct and road overbridge in Ghaziabad. On this portal pier, a Special Span of about 150 m in length is to be established. Its weight will be around massive 3200 tonnes and it will be installed at a height of about 26 meters from the ground. Special care is being taken in the assembling of this mega span due to the metro viaduct and road overbridge going below the RRTS viaduct.

The special spans will be pushed to establish at Ghaziabad and Vasundhara rail crossing from one side of the pier to reach the other side with the help of Winch and roller arrangement.

These pieces of Special Spans are factory-made, painted structures, and are ready to install directly. Hence, they save time and don’t affect the harmony of the surroundings be it population, traffic, or existing structures. The fabrication of these special spans, made of structural steel, is so fine that they don’t need any finishing post-installation and the next phase of track laying can be carried out immediately.

Also, on-site deployment of heavy machines, raw materials, and a large number of workers for such large-scale construction work is practically not feasible. Complex construction activity on a massive scale in densely populated areas can cause safety issues, may affect routine operations of existing facilities and can cause inconvenience to the common people. Considering these aspects, NCRTC has proactively adopted this unique technique that would cause minimum inconvenience to the public, ensure smooth traffic management & operations, and safe construction.

Presently, with the tireless efforts of more than 11,000 workers and 1100 engineers on the 82 km long RRTS corridor, about 900 piers of the elevated section with 40 km of foundation and 10 km of viaduct have already been completed, most of which is located in the priority section.

Along with the construction of the viaduct in the priority section, the construction work of the superstructure of all five stations – Sahibabad, Ghaziabad, Guldhar, Duhai, and Duhai depot is in advanced stages. Track laying work is going on by connecting rail tracks on the viaduct between Guldhar to Duhai, for which a mobile flash welding plant has been set up.

NCRTC team is working day and night at the sites with 17 launching gantries (Tarini) in operation for the elevated section in the corridor. The construction work for the underground stations has also started. The priority section of 17 km between Sahibabad to Duhai is targeted to be commissioned by March 2023 and the full corridor by 2025.
