AV System Design: Who Is Responsible in a Building Project?

Responsibility for AV system design in a building project typically falls to a vendor-neutral technology design consultant engaged during the design phase – not to the AV integrator, the MEP engineer, or the architect of record.

TL;DR

Responsibility for AV system design on a building project belongs to a vendor-neutral technology design consultant engaged during the design phase, not the AV integrator, the MEP engineer, or the architect of record.
Four parties touch AV over a project: the technology design consultant defines the AV program and specifications, the AV integrator installs them, the MEP engineer supports power and conduit, and the architect ensures technology is reflected in the documents.
When no one is clearly assigned the design, the AV scope falls through the cracks, and the project goes to bid without complete AV documents, which produces change orders, scope disputes, and systems that underperform.
AV design responsibility should be established at the start of schematic design, when the project team and scope of services are being set.

The technology consultant produces AV design documents that enable competitive bidding and ensure that AV requirements are coordinated with architectural, structural, and MEP systems before construction begins. Read on to explore the roles involved in AV system design, what goes wrong when responsibility is unclear, and when to assign it.

What Are the Roles Involved in AV on a Building Project?

Several parties touch AV systems over the course of a building project. Understanding who does what, and at what phase, is the foundation for structuring the project team correctly and avoiding the scope gaps that generate change orders.

Technology Design Consultant: This is the design-side professional responsible for the AV program, system specs, and coordination drawings. They should be vendor-neutral and provide specifications describing performance requirements that multiple qualified contractors can meet, rather than products from a single manufacturer.
AV Integrator: An AV integrator is the construction-phase contractor who procures, installs, programs, and commissions the systems specified in the design documents.
MEP Engineer: This person coordinates the power, conduit rough-ins, and mechanical requirements that support AV systems, but doesn’t design the AV systems themselves.
Architect of Record: The architect oversees the overall design and is responsible for ensuring that technology requirements are reflected in the project's construction documents.

On projects without a dedicated technology consultant, the architect is often left to manage the AV scope without the expertise to define it clearly – a common source of coordination gaps.

Without a technology consultant, the AV scope tends to fall through the cracks.

What Happens When Responsibility Isn't Clearly Assigned?

The most common problem in AV project delivery isn't a failure of any individual party – it's an unclear assignment of responsibility during design. Understanding these failure modes helps architects and project managers avoid them.

When there isn’t a technology consultant is engaged, the AV scope tends to fall through the cracks. Nobody designs it, and the project goes to bid without complete AV construction documents. Contractors bidding without a complete AV design will typically either exclude the scope and wait for clarification or include allowances and assumptions that don't align with the owner's requirements. Either path leads to change orders, scope disputes, or a delivered system that doesn't perform as expected.

Bringing an AV integrator to write their own scope addresses the documentation gap but creates a different problem: the integrator's spec reflects what they sell. That limits competitive bidding on the work and can produce systems optimized for the integrator's product lines instead of the owner's actual needs.

AV System Design FAQs

What Is AV System Design?

AV system design is the discipline of planning, specifying, and documenting audiovisual systems so they meet an owner's needs and coordinate with the rest of the building. It covers the system program, performance specifications, and the coordination drawings that define what gets installed and how it integrates with other trades.

Who Is Responsible for AV System Design in a Building Project?

A vendor-neutral technology design consultant, engaged during the design phase, is responsible for AV system design. They produce the AV program, specifications, and coordination drawings that allow multiple qualified contractors to bid the work and that keep AV requirements coordinated with the architectural, structural, and MEP design.

What Is the Difference Between an AV Consultant and an AV Integrator?

An AV design consultant is the design-side professional who defines vendor-neutral requirements, while an AV integrator is the construction-phase contractor who procures, installs, programs, and commissions the systems.

Keeping design and installation separate preserves competitive bidding and keeps the specification aligned to the owner's needs rather than a single manufacturer's product line.

What Happens When AV Design Responsibility Is Not Clearly Assigned?

When no one owns the AV design, the scope tends to fall through the cracks, and the project goes to bid without complete AV documents. Contractors then either exclude the scope and wait for clarification or add allowances that do not match the owner's requirements, and both paths lead to change orders and systems that do not perform as expected.

Should an AV Integrator Write the AV Specification?

Letting an integrator write their own scope closes the documentation gap but ties the specification to what that integrator sells. That limits competitive bidding and can produce systems optimized for a product line rather than the owner's actual requirements, which is why a vendor-neutral consultant should own the design.

When Should AV Design Responsibility Be Established?

Establish AV design responsibility at the start of schematic design, when the project team is assembled and the scope of design services is negotiated. Resolving it early means the rest of the design team knows what to coordinate with, and answers found during design cost far less than answers found during construction.

Does Every Project Need a Dedicated AV Design Consultant?

Projects with modest AV needs, such as a few conference rooms or basic building audio, can sometimes be handled through a design-build integrator contract.

Projects with complex or extensive AV requirements, such as auditoriums, large meeting facilities, multi-building campuses, and venues, benefit from a dedicated design-side technology consultant.

When Should We Establish AV Design Responsibility?

You should establish AV design responsibility at the beginning of schematic design, when the project team is being assembled, and the scope of design services is being negotiated.

For projects with modest AV requirements, such as a handful of conference rooms or basic building-wide audio, an owner may choose to address AV through a design-build integrator contract. But on projects with complex or extensive AV requirements – large meeting facilities, auditoriums, multi-building campuses, venues – the design-side technology consultant role is worth the investment.

Resolving AV design responsibility early means the rest of the design team knows what to coordinate with. Getting those answers during design is far less expensive than getting them during construction. Contact TMC today to learn how our experts approach AV system design for architectural projects.
