Earthworks and Environmental Construction

Hundreds of gas stations, wellsites, industrial facilities and spills have been remediated by Nelson’s Earthworks team. We have the knowledge and experience to complete your remediation, reclamation and demolition projects safely and efficiently.

Consider Nelson to be your partner when budgeting and implementing your next environmental construction project. 

Soil Stability Issues?

You don't get to pick the subsurface environment that contamination has affected. We're here to help you select the most cost effective construction methods.

No Problem

We work with specialty shoring engineers and subcontractors, your team, and regulators to design the most cost effective solution to your soil stability issues while removing contamination up to your property line.

Groundwater?

In Western Canada, our groundwater is a plentiful and precious resource. It can also transport contamination offsite and cause our clients all manners of regulatory burdens.

No Problem

Don't let groundwater wash away your project. We work with hydrogeologists, civil and geotechnical experts to manage your groundwater. Whether we are installing wellpoint systems, offsite migration prevention systems, or layering chemical oxidation material Nelson has you covered.

Why Nelson EarthWorks

What Are Your Approaches?

Our team works with one of our certified Storage Tank Removal Technicians to design a safe decomissioning plan for the legacy tanks on site. In conjunction with our Project Manager and Site Manager, we work with our client to determine if the convenience store, canopy or other infrastructure require salvage or demolition and plan those activities. 

Once the plan is in place, permits have been drawn and work is approved to move forward, we work with our clients to manage the waste from the site in the most cost effective and environmentally responsible way feasible, clean and destroy the tanks in accordance with local regulations and our safety standards, and restore the site so that it is prepared for new construction. Our clients have the option to:

  • Leave an open excavation to reinstall new storage tanks
  • Restore the site to surface with a fully restored parking lot
  • Convert the site to a park with landscaping 
  • Restore the site to gravel for future use or land sale. 
  • Create a custom solution

 

Canada has a wide range of industries that have potential to cause unintended contamination to the surrounding environment. We work with environmental consultants to effectively remediate legacy industrial sites to the standards required by all stakeholders in a project. Our team is adept at selecting the most cost effective construction approach, disposal options for waste material, and mitigation of legacy issues such as backmigration of contamination. 

When our clients call us to decomission an industrial facility we:

  • Assign a project manager to their project
  • Build a waste risk matrix for disposal options
  • Assess ground stability and water intrusion issues
  • Work with all stakeholders to effectively cost the most efficient solution

Wellsites that are ready for decomissioning have their own challenges. When presented with a wellsite by our clients, a project manager or estimator will be assigned to the client to work through options. 

  • Pre-approval in client safety program is initiated.
  • Assessment of nearby landfills for suitability is conducted.
  • Sizing of equipment for production, road use and local terrain.
  • Procurement of specialty hauling contractors with knowledge of local road systems is a key to project success.
  • Alternates to landfill are discussed – allu treatment, landfarm, thermal desorption may be more cost effective.
  • We work with our clients to conduct the right remediation for the site.

Once a gas plant has been demolished, the ground still requires management. Working with our onsite experts, project manages and specialty subcontractors, we implement the workplans made by our clients to support them in:

  • Grouting underground utilities
  • Removing contaminated soil
  • Removing or breaking up cemented infrastructure above and below grade
  • Installing systems to prevent offsite migration
  • Supporting surface restoration to the nominated site condition – whether field, forest, paved area or other solutions

Brownfield construction on legacy contaminated sites is a specialty with our team. We work with your site and it’s unique history to provide you with accurate construction costing and performance. The most common issues we encounter on legacy brownfields include:

  • Discovery of debris not recorded in site history (Phase 1 or 2 environmental reports)
  • Discovery of pocketed contamination
  • Discovery of perched watertables

Work with Nelson to help predict costs and effectively establish your construction budget. 

We frequently get asked by landowners some variation of the question “How much will it cost to restore this site so that I can build a(n) __________(Warehouse/Apartment Complex/Storefront/Etc)? Rather than answer that question directly, we go to the experts and help landowners find an environmental consultant who is qualified to seek a remedial certificate, so that the landowner has the best chance of succeeding in their property disposal, repurposing or acquistion. 

How do you manage site specific challenges?

Not every site is geotechnically stable. Sometimes you need to reach contamination to the edge of your property line. If a shoring wall, temporary shoring solution or slot cut is required Nelson is your partner. Contact us for examples of our past work or for a plan custom to your site. 

Water challenges in construction are nothing new, so you should seek a contractor who is ready to respond to the issues that water intrusion can cause – especially when the risk of contamination exists. Our team will work with you to select the right mitigation strategy for your site. That might be as simple as having storage tanks ready with some inexpensive pumps and time allotted, or as complex as drilling multiple wellpoint systems with discrete batching for testing of collected water. With in-house solutions and a strong network of subcontracors for speciality solutions, Nelson is your partner for water management success.  

If we’re digging it up, it has to go somewhere. We have a complete mapping of disposal facilities in Western Canada, a network of transportation options, and the experts you need to make your plan come to action. We are experienced in all manners of offsite disposal of contaminated soil and other materials found during the course of environmental construction and will assist your team in creating the most cost effective solution available to restore your site. 

NELSON has been recognized as a leader in the environmental industry for its ability to complete some of the largest soil remediation projects worldwide.
