Renovation projects come with a unique set of challenges. Existing conditions, occupied spaces, multiple stakeholders, tight schedules, and unexpected discoveries can all have an impact on a project’s success.

This month, we’re focusing on the importance of planning for what you know, preparing for what you don’t, and keeping everyone aligned along the way. From building the right contingency into a renovation budget to coordinating stakeholders and identifying hidden conditions early, a little extra planning on the front end can make a big difference once construction begins.

At CC&E, our goal is to help project teams anticipate challenges early, make informed decisions, and keep projects moving forward with confidence.

September’s Quick Take

Estimating Edge: Renovation Contingency

Renovations carry uncertainties that new construction often does not. Hidden conditions, aging systems, code deficiencies, hazardous materials, and work within occupied facilities can quickly impact a project budget.

That’s why contingency should reflect the project’s design stage and level of uncertainty.

As a general guide, we recommend:

  • 15–25% during pre-design (master planning and feasibility)
  • 10–15% during concept and schematic design
  • 5–10% at design development
  • 0–5% at construction documents

As unknowns are resolved, contingency can be reduced while maintaining appropriate protection for remaining renovation risks.

A well-planned contingency provides flexibility to address unforeseen conditions without compromising project priorities.

Behind the Estimate

Renovation estimating goes beyond pricing what’s shown on the drawings.

Estimators must also consider what may be hidden, including building age and condition, structural deficiencies, outdated MEP systems, hazardous materials, and potential code upgrades.

Project logistics are equally important. Occupied spaces, phasing, site access, and impacts to contractor productivity can significantly affect cost.

Identifying these risks early helps create a more reliable budget and reduces the likelihood of costly surprises during construction.

Owner/Architect Insight

This section looks at how clear roles, communication, and coordination help project teams manage the many priorities involved in renovation and capital improvement projects.

Managing Multiple Stakeholders

As owners and project teams plan renovations and capital improvements, one of the greatest challenges is managing the many stakeholders who influence a project.

Owners, architects, facility teams, finance departments, occupants, and contractors may all bring different priorities and expectations.

Establish Clear Roles Early

Effective stakeholder management starts with establishing clear roles, decision-making authority, and communication protocols early.

This helps prevent conflicting direction, delays, and costly rework while keeping decisions aligned with the project’s cost, schedule, and overall goals.

The Owner’s Representative as a Central Point of Coordination

An experienced Owner’s Representative can serve as a central point of coordination, helping manage competing priorities, facilitate communication, and anticipate concerns before they become project issues.

Successful projects require more than good design, they require alignment.

Establishing expectations early creates a stronger foundation and helps the entire team move forward with confidence.

September’s Hard Hat Tip: Scheduling Around the Academic Calendar

Scheduling construction projects around the academic calendar is essential for minimizing disruptions to students, faculty, and school operations.

Planning major work during holidays, weekends, or summer breaks allows contractors to complete noisy, hazardous, or disruptive activities with minimal impact on learning.

This approach improves safety, maintains educational continuity, supports efficient project management, and helps schools reopen on time with completed facilities ready for use.
