Specialists in Cost Planning & Project Management for Every Stage of Your Build
Cost Planning
Effective cost control begins long before construction starts. At CM3 Consultancy, we provide detailed cost planning and budget management from the earliest stages of your project. By assessing design proposals, material choices, and current market conditions, we help clients maintain financial certainty and make informed decisions. Our proactive approach makes sure your project remains on budget and financially viable throughout its lifecycle.
Design Development
Our design development service bridges the gap between creative vision and practical delivery. Working closely with architects, engineers, and contractors, we refine design concepts to ensure they are cost-effective, buildable, and compliant. By integrating cost and programme advice early in the process, we help achieve the ideal balance between design quality, functionality and value.
Construction Management
We take a hands-on approach to construction management, overseeing every stage of the build to ensure quality, safety and efficiency. From coordinating trades and suppliers to managing on-site progress, we provide clear communication and professional leadership. Our goal is to deliver projects that meet design intent, exceed expectations, and are completed on time and within budget.
Project Planning & Programming
Thorough planning is key to a successful project. We produce detailed project programmes and construction schedules, mapping out each stage from procurement through to completion. This structured approach enables better coordination, effective risk management, and accurate progress tracking. With clear timelines and achievable milestones, our clients benefit from predictable delivery and minimal disruption.
