A: The earlier, the better! Ideally during RIBA Stage 2 (Concept Design) when design is still fluid and changes are low-cost. We can still provide value at Stage 3 (Spatial Coordination), though options become more constrained. Post-Stage 4, analysis is typically limited to value engineering specific elements.

A: We typically recommend 5-7 scenarios for most projects. This provides sufficient breadth without overwhelming decision-makers. For complex projects with multiple variables, we may evaluate 10-12 scenarios. For simple decisions (e.g., single material choice), 3-4 scenarios may suffice.

A: We can work with conceptual sketches, single-line diagrams, or written descriptions for early-stage analysis. For higher-accuracy analysis, we recommend simple BIM models for each major scenario (LOD 200-300 is sufficient). We can also assist with rapid concept modeling if needed.

A: At concept stage (RIBA 2), expect ±15-20% accuracy - sufficient for scenario comparison. At spatial coordination (RIBA 3), we achieve ±10-15%. The key is that all scenarios use consistent methodology, so relative comparisons remain valid even if absolute costs have margins.

A: Yes! If you have a target (e.g., “reduce capital cost by 15%”), we’ll design scenarios specifically to achieve that goal while minimizing impact on performance. We’ll identify multiple pathways to the target, allowing you to choose the best tradeoff between cost, time, and quality.

A: Absolutely. Every scenario includes embodied carbon calculation and operational energy assessment as standard. We can also include detailed BREEAM credit analysis, circular economy potential, material provenance, and whole-life carbon modeling if sustainability is a key priority.

A: We provide a detailed implementation roadmap including specification notes, procurement strategies, and risk mitigation measures for your chosen scenario. Many clients then engage us for detailed cost estimation, value engineering refinement, or ongoing cost control as the design develops.

A: Yes! We frequently analyze procurement strategy options (traditional, design-build, management contracting, NEC vs JCT contracts), phasing strategies, temporary works solutions, and logistics alternatives. The same multi-criteria framework applies to any significant project decision.

A: Our decision matrix includes weighted criteria set by your team. You can assign higher weights to factors like design quality, brand alignment, or user experience. This ensures the analysis respects both objective metrics (cost, time) and subjective priorities (aesthetics, stakeholder preferences).
