Accurate Pricing. Lower Risk. Greater Control.
GMP Development for Smarter Construction Budget Control
GMP Development — or Guaranteed Maximum Price development — is a cornerstone of effective construction management. At Quarry View Building Group, we help clients set a realistic GMP during preconstruction, giving project owners clarity, control, and confidence before a shovel ever hits the ground.
Our approach to GMP Development combines deep experience in general contracting, sharp attention to detail, and a risk-based approach to budget forecasting. With a focus on clear project scope, transparent pricing, and solid planning, we work with construction managers, general contractors, and design teams to deliver a full GMP package that sets your construction project up for success.
What Is a GMP and Why Does It Matter?
A Guaranteed Maximum Price is a binding agreement between the owner and the general contractor. It establishes that the total project cost will not exceed a set maximum — unless the scope changes. This creates clear budget boundaries and shifts most cost overrun risk onto the contractor.
A typical GMP includes:
-
Direct costs (labor, materials, equipment, subcontractors)
-
General conditions (site management, safety, supervision)
-
Contractor’s fee (often a percentage of direct costs)
-
Contingency amount (to cover unforeseen minor costs)
When properly developed, a GMP contract offers several benefits:
-
Greater control over project costs
-
Lower chance of cost overruns
-
Shared risk and cost savings with the construction manager
-
More accurate financing and loan forecasting
GMP isn’t just a financial tool — it’s a roadmap for better project management, tighter scheduling, and higher quality standards.
Our Approach to GMP Development
At Quarry View, GMP Development begins early in preconstruction. This allows us to align construction drawings, project scope, and estimates before pricing is locked in. Here’s how we build your GMP:
1. Scope Clarity
We define the intended use, size, materials, and performance needs of the finished product. Clear scope is the backbone of any solid GMP. Vague scopes lead to extra costs, disputes, and change orders.
2. Trade Partner Input
We bring in trusted subcontractors to provide early estimates and evaluate constructability. This keeps pricing realistic and anchored in actual labor, material costs, and market conditions.
3. Estimate Validation
Our team reviews all construction drawings and specifications. We apply current cost data to build the GMP line by line — including direct costs, contractor responsibilities, and allowances for items not yet finalized.
4. Risk Review
Every construction project carries risk. We assess project complexity, unknowns, and external risks, which inform the contingency amount. Our goal isn’t padding — it’s smart planning.
5. Shared Savings
We often structure GMPs with shared savings provisions. If the project comes in under budget, the savings are split between the owner and contractor — encouraging efficiency and reducing waste.
GMP Development and the Construction Industry
We’ve seen firsthand how strong GMPs prevent problems down the road. In many cases, projects exceed budgets due to poor planning or unclear scope. Our mission is to address these issues before construction begins.
This isn’t theory. Our GMP work spans complex projects — from manufacturing facilities to adaptive reuse and design-build projects. We bring hands-on knowledge of building systems, quality standards, and real-world pricing.
We understand the unique GMP needs across project types — whether it’s a biotech lab with strict Good Manufacturing Practice (GMP) standards or an equestrian barn with custom timber craftsmanship. The principles remain the same: plan thoroughly, estimate honestly, and stick to the contract.
Understanding GMP in Regulated Environments
For clients in regulated industries, such as pharmaceuticals or life sciences, our process is even more detailed. These projects often involve process validation, controlled environments, and specialized equipment.
In this context, GMP also refers to Good Manufacturing Practice — a set of quality regulations ensuring consistent production and control. We understand how these standards influence design choices and building systems.
We work with design teams and owners to align features with quality systems and GMP compliance, including:
-
Sealing systems for clean rooms
-
HVAC configurations to reduce contamination risk
-
Material selections for chemical resistance
-
Site layouts that support efficient workflows
A Strong GMP Needs Strong Oversight — That’s Where We Come In
Compared to lump-sum or cost-plus contracts, a GMP agreement gives owners more protection. If costs exceed the maximum due to contractor error, the contractor absorbs the overage. However, GMP contracts still require:
-
A well-defined project scope
-
Strong project management oversight
-
Coordination between the construction manager and trade partners
-
Frequent budget reviews to prevent drift
That’s where Quarry View stands out. Our disciplined approach keeps GMPs realistic, and our communication keeps all stakeholders aligned.
What Makes a Realistic GMP?
A realistic GMP is based on current cost data, market input, and actual design drawings — not placeholders or guesses. If the GMP is too low, you’ll face change orders and added costs. If it’s too high, you lose control and potential savings.
A balanced GMP should:
-
Account for all general conditions
-
Include a fair contractor’s fee
-
Carry a lean but sufficient contingency
-
Reflect real labor, material, and site conditions
It should also have clear contract terms defining risk responsibility. We collaborate closely with owners and designers to ensure GMP Development supports both transparency and accountability.
Reliable GMPs Across Diverse Projects
Our preconstruction team is known for clarity, precision, and integrity. We’re not just estimators — we’re builders. We understand how budgets turn into buildings and how preconstruction choices shape real outcomes.
We’ve supported GMP development for a range of projects, including:
-
Hospitality facilities with complex layouts and finishes
-
Equestrian centers requiring large spans, specialized ventilation, and heavy use
-
Restoration and adaptive reuse builds balancing scope flexibility with preservation
-
Commercial projects with tight deadlines and multiple stakeholders
-
Mass timber and heavy timber structures needing coordinated sourcing and joinery
-
PHIUS-certified buildings where envelope strategies drive budgeting
Each project had unique challenges — but all benefited from a strong GMP foundation.
Let’s Build Smart from the Start
If you’re in the early stages of planning a construction project or refining your manufacturing process, now is the time to engage in GMP Development. A Guaranteed Maximum Price protects your investment by defining cost limits and minimizing risk.
When Quarry View joins early, we align your design, budget, and schedule before construction begins — adding clarity where it matters most.
