Right-Sized Useful Engineering
Right-sized engineering that turns a capital decision into a buildable scope — without over-engineering what doesn't need it.
A capital decision is only as good as the design that executes it. Under-designed, a good idea becomes an expensive problem in the field. Over-designed, a straightforward upgrade costs twice what it should and takes twice as long to approve.
SPG design engineering is calibrated to what the decision actually requires.
- Buildable Scopes - Transform capital decisions into construction-ready designs calibrated to project requirements
- Risk Mitigation - Identify constructability issues and program compliance gaps before construction starts
- Technical Expertise - Professional Engineers and Certified Energy Managers with 3,525 projects of institutional knowledge
What we design

Built by engineers who also do the work
SPG's design team includes Professional Engineers (P.Eng) and Certified Energy Managers (CEM). These are the same people who run energy audits, deliver Building Condition Assessments, and manage implementation. The institutional knowledge from thousands of projects is in the room when your design gets reviewed.
What building systems does SPG design engineering cover?
SPG design engineering covers mechanical systems (HVAC redesigns, DHW upgrades, heat pump conversions), building envelope improvements (insulation, air barriers, glazing), electrical and controls (BAS upgrades, lighting, metering), renewable systems (solar PV, EV charging, battery storage), and commissioning specifications.
How does SPG design engineering de-risk capital decisions?
Our design engineering turns capital decisions into buildable scopes by matching design depth to your decision requirements, conducting constructability reviews, coordinating with operations teams, and aligning with incentive program technical requirements before construction begins.
Do you provide right-sized design solutions for different project stages?
Yes, we calibrate design depth to match your specific needs: concept-level design for scoping and approvals, schematic and design development for procurement, construction documents for bid-compete projects, and design-build specifications for fast-track delivery.
Can you track design decisions through the Building Improvement Cycle?
Absolutely. Design sits in Stage 4 of the Building Improvement Cycle, using audit data and BCA findings from Stages 2 and 3 as inputs to produce buildable scopes that Stage 5 executes against, with full traceability and decision documentation.
What sets SPG design engineering apart from other firms?
Our design team includes Professional Engineers (P.Eng) and Certified Energy Managers (CEM) who also conduct energy audits, deliver BCAs, and manage execution. Institutional knowledge from 3,525 projects informs every design review and constructability assessment.
How quickly will I receive design deliverables?
Design timelines depend on scope and depth. Concept-level designs typically complete within weeks for budgeting and approvals. Schematic and design development phases take longer for detailed coordination. Construction documents follow project-specific schedules aligned with procurement and permitting requirements.
