A Step by Step Guide To Achieve A Successful Demolition Project
Published by jdelbo on
There are several motivations for going for a building demolition job. If you have found a site that you desire, but there is a structure in place, then you would consider knocking it down instead of renovation work because of the following reasons:
- The building is blighted:
A blighted building can’t be utilized due to being dilapidated, deteriorated, and violates health and safety standards.
- The building is a health hazard:
A building is a health hazard if it has moisture leaks, substantial mold build-up, or contains uncontrollable amounts of hazardous materials such as asbestos.
- The building’s foundation is faulty:
An indication of a compromised foundation is slanted floors which cause a building to fail inspections.
- The local area is slated for redevelopment
Even utilizable buildings will need to give way for more economically feasible structures due to zoning changes (residential areas have developed into commercial areas) or practicality.
Here below is a step-by-step demolition guide to assure yourself of a trouble-free operation.
Cost and hindrances vary by state. Local and state authorities heavily regulate sites and should satisfy federal, state, and local requirements. In Massachusetts, for instance, you need to file AQ 06 with MassDEP construction/demolition notification that should cover several things. One of these is satisfying the Dust, Odor, Construction, and Demolition Regulations covered by 310 CMR 7.09.
It is also essential to consider if the demolition and construction will disturb any natural formations, for instance, or wetlands. Most importantly, if the building holds a historical significance.
After filing your permit, it would help to lay down all required to ensure the operation’s smooth running.
Having a qualified team to execute the operation is essential, and OHSA laid down the guidelines for team members eligible to work on demolition jobs. Contractors have qualified personnel trained to do specialized tasks such as steel tank disassembly or operation of demolition equipment.
- Cost Control:
Having a dedicated cost expert specialized in construction/demolition work is very helpful. They should work closely with the project manager to help control cost by looking over possible cash leaks. Cash leaks and unintended cost burdens can be addressed by thorough site inspection, thorough planning, and allowing for contingencies in the budget. For instance, management of old plumbing or sudden discovery of HBMs can drive cost.
- Site Inspection:
Site inspection is crucial to control the overall cost of the project. An important point to consider is the existence of asbestos or other HBMs. The presence and consequent Control and management of such materials can drive costs up if discovered in an unintended manner. Site inspection should result in thorough planning, which will benefit the project’s safety, price, and lead-time.
- Site Inventory:
Lastly, you will find unused articles on the site. Old office equipment, reusable construction materials, and other leftover items are usually found on site. You can have these articles sorted, and some can be donated or slated for reselling or recycling. Exhaust all possible means on articles found before you relegate some of them to the landfill.
The Demolition Stage
You should be ready for the demolition operations when you have made thorough preparation, site inspection, site inventory, filed the permits, and planned for the costs.
Different buildings will require different approaches. These are several demolition methods you need to consider:
- Deconstruction: this is an environment-friendly and safe method. This method is best suited for older structures meant for remodeling. It usually requires working on sections while retaining the original structure.
- Implosion: This is a cost-friendly method for demolishing huge structures preferably located in low population density areas.
- Excavator Demolition: This is best done for toppling tall walls. Various attachments are used, such as shears, hydraulic hammers, and crushers.
- Wrecking Ball Demolition: This used to be a common and cost-friendly demolition method. However, it is associated with dust generation, and the debris created tends to be unsafe.
After selecting the appropriate demolition method, it will help so much that safety considerations are in place. Implementing safety measures prevents unnecessary expenses and hassles created by safety issues and accidents.
The Cleanup Stage
Be cautious at this stage because complacency might set in. Experienced excavators and disposal experts come with a price. It is necessary to enlist their help, but it would help if you integrate some tasks into your demolition operations. One task suggested is to properly manage signages and warning signs that you might be able to repurpose.
