Structural Dismantling at Haverhill Substation

Haverhill Substation Abatement & Demo

Haverhill, MA

Services Provided
Abatement & Demo
Project Challenge
Because the work was located close to residential buildings that needed to remain in place, the project required a carefully planned execution strategy to prevent impacts to surrounding structures.
Solution
Staging was constructed between the building to be retained and the structure scheduled for demolition. Demolition was safely executed using high-reach excavators and precision small equipment.

Services Provided
Abatement & Demo
Project Challenge
Multi-phased project requiring management of 10 individual waste streams of differently classified hazardous materials.

Environmental Remediation at the Museum of Science in Boston, MA

Museum of Science

Boston, MA

Services Provided
Abatement & Demo
Project Challenge
Multiple areas within the Museum that needed to be abated while still being open to the general public.
Solution
This required a “rolling containment” schedule so one area at a time could be cordoned off, making it a safe for the general public and giving our crews the opportunity to perform their work. This was achieved with a host of different scenarios including overnight work, closing off sections completely in order to keep everyone safe.
