Construction Management (CMAR)

One accountable partner, from design to delivery. Our Construction Manager-at-Risk approach unites pre-construction insight and general contracting muscle under a single guaranteed price.

Construction Management at Risk — CMAR — is the best of both worlds. We join your team early, during design, to provide the same rigorous pre-construction planning that protects your budget. Then we take on the risk of building the project under a guaranteed maximum price, delivering it with the discipline of a seasoned general contractor.

The result is a collaborative, transparent partnership in which the builder, owner, and designer all pull in the same direction from day one — instead of meeting for the first time on bid day.

How CMAR works

01

Join the design team

We come on board early as your trusted construction advisor, contributing budget, schedule, and constructability guidance while the design is still flexible.

02

Establish the GMP

As the design matures, we develop and commit to a guaranteed maximum price — giving you cost certainty before construction begins.

03

Build at risk

We deliver the project under that price, assuming responsibility for overruns and returning savings to you. Open-book accounting keeps every dollar visible.

Why owners choose CMAR

  • Cost certainty early — a guaranteed maximum price you can take to your lender and your board.
  • Fewer surprises — constructability and pricing input during design eliminate bid-day shocks.
  • Faster delivery — fast-track scheduling lets construction begin before every detail is finalized.
  • Aligned incentives — open-book pricing and shared savings put the whole team on your side.

Frequently asked questions

What is Construction Manager-at-Risk?
CMAR is a delivery method where the construction manager joins during design to provide pre-construction services, then builds the project under a guaranteed maximum price (GMP) — combining the planning benefits of pre-construction with the execution of general contracting under one accountable team.
What is a guaranteed maximum price (GMP)?
A GMP is a contractual ceiling on project cost. Horizon assumes the risk for costs above it, while savings below it typically benefit the owner — aligning everyone around an efficient, transparent build.
Why choose CMAR over design-bid-build?
CMAR brings the builder's cost and constructability expertise into design, reduces bid-day surprises, allows fast-track scheduling, and fosters a collaborative rather than adversarial team — ideal for complex commercial and multi-family work.
