Basement Lowering, Underpinning, and Renovation Services by CSC ENGINEERING INC
Planning to lower your basement floor or undertake underpinning for your property? CSC ENGINEERING INC offers comprehensive design and engineering services tailored to meet municipal requirements for basement projects.
Design Package Costs:
- Underpinning Design Only: Starting from $2,800
- Complete Basement Interior Design: Approximately $3,800 (includes floor drains, laundry room layout, insulation specifications, stud wall partitions, etc.)
Additional charges apply for basement walkout additions.
Design Methods:
- Underpinning Foundation Walls: We execute a staged underpinning process, reinforcing the foundation to safely lower the basement floor. Costs typically average around $400 per linear foot of foundation wall underpinned.
- Benching: While less common due to updated regulations, we can implement a stable soil slope method with reinforced concrete benching for moderate basement floor lowering (up to 12 inches).
Key Considerations:
- Municipal Compliance: We ensure all designs meet stringent municipal standards and regulations.
- Periodic Inspections: Our Structural Engineers conduct periodic inspections during underpinning operations and provide Site Review Reports to municipalities.
- Plumbing Assessments: Prior to construction, we recommend plumbing checks to ensure sanitary sewer connections align with new basement levels.
- Neighbouring Footings: We assess potential impacts on neighbouring footings and provide tailored engineering solutions as needed.
Water Table Concerns:
- Optimal Conditions: Ideally, the water table should be at least 24 inches below the newly underpinned wall base to avoid structural issues and ongoing pumping costs.
Additional Considerations:
- Sanitary Ejector Pump: Installation may be required if sewer connections are higher than new basement levels (estimated cost: $4,000).
- Unique Situations: Each project is unique, and our engineering solutions are customized to address specific challenges and soil conditions.
