Peer Design Review, Code Compliance Review, Bid Readiness Review

The Problem

Construction documents go to bid with mistakes in them. It happens on virtually every project, regardless of the caliber of the design team. The question isn’t whether there are issues — it’s whether they get caught before they cost real money.

A missed code requirement discovered during plan review delays the permit. A coordination conflict between mechanical and structural found during installation becomes a change order. An undersized duct main identified during balancing becomes a complaint from every tenant on the third floor. A sequence of operation that contradicts the equipment submittal becomes a commissioning deficiency and a finger-pointing exercise.

These aren’t signs of a bad design team. They’re the natural result of complex projects moving fast, with multiple disciplines working in parallel under deadline pressure. Even the best engineers benefit from an independent review by someone with fresh eyes and broad experience.

What Peer Review Covers

Our review is not a cursory spot-check or a rubber stamp. We conduct a thorough, systematic examination of the mechanical construction documents with a focus on the things that actually cause problems in the field:

Code Compliance — We verify compliance with applicable mechanical, energy, and fire codes. This includes ASHRAE 90.1 or IECC energy code requirements, IMC provisions, NFPA requirements, and any jurisdiction-specific amendments. We check the things that plan reviewers flag — and the things they miss.

Design Intent Clarity — We evaluate whether the documents clearly communicate the design intent to the contractor. Ambiguous or incomplete information on the drawings and in the specifications is one of the biggest drivers of RFIs and change orders. We identify where the contractor is likely to have questions or make assumptions.

Constructability — We look at the design from the contractor’s perspective. Can this actually be built as drawn? Are there routing conflicts in tight ceiling spaces? Are access and maintenance clearances adequate? Are there sequences of construction that the phasing plan doesn’t account for?

Coordination — We review mechanical systems against structural, architectural, electrical, and plumbing documents for conflicts. Coordination issues caught on paper cost a fraction of what they cost in the field.

Maintainability — We evaluate whether the systems as designed can be reasonably maintained over the life of the building. Equipment access, filter changeout clearances, valve accessibility, drain provisions, and isolation capability all matter to the facility team that will live with this building for decades.

Energy Code Compliance — Energy code is increasingly complex and increasingly enforced. We verify that equipment efficiencies, economizer requirements, controls provisions, and system configurations meet current code requirements.

Our Approach

We typically conduct peer reviews at one or two key milestones:

Progress Review (50–75% Design Development or early CD) — This is where our input has the most impact. The design is far enough along to review substantively but early enough to correct course without major rework. We provide a detailed comment log organized by priority and discipline, with specific references to drawing sheets and specification sections.

Pre-Permit / Pre-Bid Review (90–100% CD) — A final review before documents go out the door. At this stage, we’re focused on catching remaining code issues, coordination gaps, and anything that will cause problems during plan review, bidding, or construction.

We deliver a structured review report — not a vague list of opinions, but specific, actionable findings with references and recommended resolutions. We’re also available to discuss findings directly with the design team if that’s helpful.

Why Our Background Matters

Effective peer review requires pattern recognition that only comes from experience. You have to have seen enough projects go through construction to know where things typically go wrong for each building type, system type, and project delivery method. You have to understand not just the codes but how plan reviewers interpret and enforce them. You have to be able to read a set of documents and anticipate the contractor’s questions before they’re asked.

We’ve spent over 23 years designing mechanical systems across healthcare, higher education, laboratory, commercial, and institutional projects — and over a decade of that time leading and reviewing the work of other engineers. We’ve seen what works, what causes problems, and what gets missed. That experience is what makes the review valuable.

Who This Is For

• Building owners who want independent quality assurance before committing to a bid or permit set
• Architects who don’t have in-house mechanical engineering review capability
• General contractors and construction managers who want to reduce RFI volume and change order risk
• Smaller MEP firms that need a senior-level technical review they don’t have on staff
• Owner’s representatives managing design quality on behalf of their clients

FAQ

• What is an HVAC peer review? An HVAC peer review is an independent examination of mechanical construction documents by a qualified engineer who was not involved in the original design. The reviewer checks for code compliance, coordination conflicts, constructability issues, and design clarity — things that are easy to miss when you’re close to the work. The goal is to catch problems on paper, before they become change orders or field issues.
• When in the project should I schedule a peer review? The highest-value window is at 50–75% design development or early construction documents, when the design is substantive enough to review but early enough to correct without major rework. A second review at 90–100% CD — before the documents go out for permit or bid — catches any remaining issues and confirms bid readiness.
• How is a peer review different from the engineer of record reviewing their own work? The engineer of record is responsible for producing the documents — their review is a quality check of their own work. A peer reviewer brings fresh eyes, no stake in the existing design decisions, and pattern recognition from reviewing many different projects and design teams. That independence is what makes the review effective.
• What does the peer review deliverable look like? You receive a structured comment log with specific findings organized by priority and discipline, referencing exact drawing sheets and specification sections. Each finding includes a recommended resolution. It’s an actionable document — not a vague summary of observations.
• Who typically commissions a peer review? Building owners, developers, and owner’s representatives who want an independent check before committing to a contractor price or pulling a permit. It’s also common on projects where the owner has had past experience with costly field issues and wants a second set of eyes before construction starts.
• Does a peer review slow down the project schedule? No — a typical peer review is completed within one to two weeks of receiving the documents, and findings are delivered as a comment log that the design team can work through in parallel with other project activities. Catching issues at this stage is significantly faster than resolving them during construction.
