As you are already aware, the City of Ottawa is constructing a new pump station and forcemain along Maple Grove Road, Terry Fox Drive and Katimavik Road up to Eagleson Road. The forcemain route on Katimavik Road includes rock that requires excavation. Blasting is required as part of this element of construction.
Who: Doran Contractors Limited is performing the construction work on behalf of the City of Ottawa. Doran has subcontracted the blasting to M-Roc and the pre-blast inspection, vibration monitoring, and notifications to Explotech.
Why: Part of the forcemain route on Katimavik Road includes rock that requires excavation. Blasting is required to remove rock to prepare for the placement of the forcemain. The Contractor will conduct its work in accordance with an approved blasting plan that meets City of Ottawa requirements. Pre-condition audits were requested on adjacent structures, including residential properties to document the existing conditions.
What: The use of explosives in construction is heavily regulated by both Provincial and Federal legislation aimed at ensuring safety and maintaining vibrations within allowable limits that will not damage neighbouring structures. The Contractor’s blasting plan is designed to ensure that blasting-induced vibrations are kept well below levels that have been shown to cause damage to adjoining properties.
The constant monitoring of vibration levels near the blasting site serves to ensure that neighbouring structures, including foundations, will not be harmed by the construction. The effectiveness of the monitoring and blasting plan will be tested by the use of small charges on the first day of blasting. These will then be increased to the planned charge size, and vibration monitoring, independently verified, showing that all readings remain within allowable limits. While you may still feel vibrations, they should be well below the level that would pose a risk to buildings.
Where: Blasting will occur on Katimavik Road from Terry Fox Drive to Castlefrank Road.
When: Blasting is projected to begin the week of May 23, 2016 for approximately 18 weeks through to the end of September 2016 in various locations on Katimavik Road between Castlefrank Road and Terry Fox Drive. Blasting will not take place on Sundays and statutory holidays.
The Contractor will distribute a notice 15 days prior to the start of blasting to properties within 150 meters of the blasting area, with the expected blasting schedule. Further notices will be provided if required due to changes in the blasting schedule, the day before the start of blasting, and to advise that blasting has been completed in that area.
Doran Contractors Limited will take every precaution to minimize interruptions to the everyday life of your family and/or the operation of your business, but as you can appreciate, there may be some inconvenience during the course of the construction, such as delays and traffic detours when travelling through the construction zone, noise, dust and vibration. We would like to thank you for your co-operation. Every effort is being made to reduce the construction impacts in your community.
The City of Ottawa Noise By-law (2004-253) allows construction activity to occur weekdays between 7 am and 10 pm. On Saturdays, work is permitted between 7 am and 10 pm while Sunday and Statutory holiday work is allowed between 9 am and 10 pm.
If you wish to receive updates directly, please provide the City’s Project Manager with your e-mail address or your postal address.
The Contractor is required by the City to carry liability insurance before any work may proceed. You may be asked by Explotech (a firm appointed by Doran Contractors Limited) for permission to survey your property before the work commences, as Contractors typically conduct pre-construction inspections to document existing conditions for insurance purposes. It is your choice whether or not you wish to have the inspection conducted on your property but we recommend that you do. You may also want to complete a survey yourself, before the work starts, to record the condition of your building. This survey should include photographs and / or video.
The Contractor is fully responsible for any damage to private property as a result of their construction activities. If you think that damage occurred to your property as a result of construction, please contact Doran directly. Every effort is being made to minimize noise and disruptions while this work is underway.
Accessibility is an important consideration for the City of Ottawa. The City makes every effort to provide access through and around construction sites. If you require special accommodations, please contact the undersigned.
For any additional information regarding this project, please contact the City Project Manager or 3-1-1.
