BLASTING TECHNOLOGY, INC.
NOTICE OF BLASTING
Starting approximately in early April 2013 and continuing until completion, we will conduct drilling and blasting in order to facilitate rock excavation on the Lalamilo Housing Phase 2A project site which is near your property. Prior to blasting, the blast area will be blocked by guards and the site will be secured. Warning signals will be given, the blast will be fired. After an inspection of the blast site, the all clear signal will be given. Your safety and the safety of all the surrounding property as well as the safety of everyone on the project site is our utmost concern.
WHAT TO EXPECT DURING A BLAST
When a blast is fired there is a ground vibration and air displacement known as “air overpressure”. You will able to feel vibration and air overpressure during the blast. On this project the blasts will last for a second or two. Blasting will take place between 2:00 and 5:30 PM.
SEISMIC MONITORING, CONSULTANT
We have worked with an independent consultant to assist in determining the impact of blasting in this area. To remove speculation about the amount of vibration generated by the blasts we will use seismic monitoring devices to measure and record the vibration level of each blast.
SEISMIC MONITORING ON YOUR PROPERTY
As we progress from one area ofthe project site to another, seismic monitoring locations will change to monitor the structures nearest to the blast. We may request permission to come onto your property to place a small monitoring device approximately 6″ x 3″ into the ground. The device will be removed daily after blasting is completed. If you prefer that we do not come onto your property please contact us at the phone number listed below.
If you have any questions or concerns about the blastiug please contact us at theBlasting Technology, Inc. office: 808-874-5554.
