1. Blasting

Blasting being a primary operation in mining, quarrying and construction work, needs to be conducted as safely as possible. As it involves the use of explosives, it can result in the loss of men, material and money if not done rightly. To avoid this, there are some key points that need to be looked at before blasting. 

Why do you need blasting advisory?

The aim of any project is quality output in the most economical way. For example, using high quality and uniformly sized explosives might seem expensive at the start, but will greatly reduce costs in the end.

A guide to the right blasting plan will not only help you achieve the desired outcome but also save 20% on overall costs. To this end, there is no better guide than Uttam Blastech, with over 25 years of experience. From helping clients plan their blasting in a public area to supervising blasting in extremely challenging geographical areas, Uttam Blastech will leave no stone unturned for a safe and cost-effective blast.

How does a pre-blast survey protect your overall business?

Pre-blast surveys, for the most part, will help gain the trust of the local people as well as gather third-party evidence and information of the site surroundings before blasting. 

In case a pre-blast survey is not done and after blasting the site surroundings seem to have cracks, the negative blasting claims can affect the reputation of the business. In a worst-case scenario (damage to men or material), it may lead to litigations and indefinitely throw the builder out of the market.

Uttam Blastech saved DLF from all litigations during a blasting project in an area with historic properties (sensitive to low-level vibrations)

Case Study 1

Client DLF Laing O Rourke (India) Ltd
Project and Constraint:Blast 300,000 m³ of rock in a location which was 450m from the Hyderabad Police Commissioner’s office, 1 km from the Secretariat and in close proximity to heritage structures. DLF approached Uttam Blastech to conduct a pre-blast survey and help conduct the entire blasting operation
Our Approach:Create documentation that can stand as evidence in a legal tangleThird-party monitoring of all the blasts to act as evidence in case of litigationEnsure that the contract adheres to prescribed vibration limits
Final Outcome:DLF safely blasted and excavated 250,000 m³ of rock from the site.

Why is vibration monitoring so important?

Beyond permissible limits, vibrations can most definitely result in the rupture or falling of masonry in the site, damage to structures surrounding the blasting area (if the project is in the vicinity of a public place), environmental impacts, flyrock and in some cases, cause fear and worry in the people, on and around the site. 

With a site-specific equation and extensive third-party evidence, Uttam Blastech rightly protects every client from unnecessary claims by ensuring all resulting vibrations fall under prescribed limits.

Case Study 2

Client GVK
Project and Constraint:When the prominent Indian conglomerate, GVK was constructing a new mall in Banjara Hills in 2003 the neighbouring residents almost filed a court case against the developer citing damages due to the blasts. Uttam Blastech was brought on-board to assess vibrations and protect the developer
Our Approach:Monitor ground vibrations in the nearby structures of blasting through seismographs and documented the recordings thoroughly
Final Outcome:The recordings showed that the ground vibrations were within the prescribed limits and the client was able to carry on the work without further delay

Why do you need legal advice before blasting?

If the blasting method and its accessories are not compliant with the industry and environmental standards, it will most likely ensue in major litigation, that will damage the reputation of the builder and company. 

Proceeding legally will help conduct a worry-free blasting and in any case of a crisis in the future, will help sue the building company as per their country standards. Uttam Blastech will help you circumvent every obstacle that might come your way by identifying all important statutory permissions.
