Construction administration is the phase of a construction project where the drawings, specifications and contracts meet the realities of the job site.

For architects, engineers and other design consultants, construction administration — often shortened to CA — is the process of administering the construction contract during construction. It includes responding to questions, reviewing submittals, observing construction, documenting decisions, reviewing changes and helping move the project from the start of construction through completion and closeout.

It is also one of the most misunderstood parts of the architectural process.

Construction administration is not the same as construction management, and the architect is generally not responsible for supervising the contractor’s means, methods or site safety.

Instead, good construction administration is about protecting the design intent, administering the contract fairly, maintaining clear documentation and helping the project team navigate the hundreds — sometimes thousands — of decisions that happen once construction begins.

In simple terms: construction administration helps turn the contract documents into a completed building.

A project can have an excellent design and a coordinated set of construction documents and still encounter significant challenges once construction begins.

Existing conditions are uncovered.

Products become unavailable.

Contractors find conflicts between drawings.

Owners request changes.

Consultants revise details.

Building officials ask questions.

And sometimes what looked perfectly reasonable on a drawing simply doesn’t work when someone tries to build it.

Construction administration provides the framework for dealing with these issues.

Good CA helps the project team:

Construction administration isn’t simply paperwork after the design is finished.

It is an essential part of delivering the project.

The architect’s role changes significantly when a project moves from design into construction.

During design, the architect’s effort is largely focused on developing and coordinating the drawings and specifications.

During construction, the focus shifts toward interpreting, reviewing, observing, coordinating and documenting.

Depending on the contract, the architect may:

The architect is generally evaluating whether the work is progressing in general conformance with the contract documents.

That distinction matters.

The architect is typically not continuously inspecting the work or directing the contractor’s workers. The contractor remains responsible for construction means, methods, techniques, sequences, procedures and site safety, subject to the requirements of the construction contract.

The architect’s role is to administer the contract — not build the building.

Construction administration generally begins when the project transitions from procurement into construction.

Before work starts on site, the project team should establish how construction information will flow.

This may include:

Getting these processes established early can prevent months of confusion later.

Construction administration then continues throughout construction and generally extends through completion and project closeout.

Every project is different, but most construction administration revolves around a common group of activities.

These processes work together to create a documented flow of information between the owner, contractor and consultant team.

Here’s the big picture.

A Request for Information, or RFI, is used when the contractor needs clarification or additional information regarding the contract documents.

RFIs are one of the most common communication tools used during construction and create a formal record of the question and response.

A good RFI process helps questions get to the right person, receive a clear response and remain documented for the project record.

Before many products and systems are fabricated or installed, the contractor submits information to the consultant team for review.

These submissions may include shop drawings, product data, samples, schedules and other technical information.

Submittal review is an important checkpoint between the contract documents and what ultimately gets fabricated or installed on site.

Learn more → Shop Drawings / Submittals

Construction site visits allow the architect and consultants to periodically observe the progress and quality of the work.

The consultant may review completed work, current construction activities, mockups, deficiencies and items requiring further coordination.

Observations are typically documented through field reports or site review reports.

Site reviews are an important part of CA, but they should not be confused with continuous inspection or supervision of the contractor.

Regular construction meetings bring the owner, contractor and consultant team together to discuss the status of the project.

Meetings commonly address schedule, RFIs, submittals, changes, site conditions, consultant coordination and upcoming work.

Good meetings do more than generate minutes.

They help identify problems early, establish responsibilities and keep decisions moving.

Not every clarification during construction requires a change to the contract price or schedule.

Supplemental instructions — sometimes called site instructions or architect’s supplemental instructions depending on the contract and jurisdiction — provide a formal method of issuing certain instructions or clarifications during construction.

The exact terminology and authority of these documents depends on the construction contract.

Learn more → Supplemental Instructions (SI)

Changes happen on almost every construction project.

Before some changes are incorporated into the contract, the contractor may be asked to provide pricing or information describing the potential cost and schedule impact.

This creates an opportunity for the owner and consultant team to understand the implications of a proposed change before proceeding.

Learn more → Proposed Changes

When a change affects the construction contract, it needs to be properly documented.

A change order is one of the primary documents used to formally modify the contract, including agreed changes to the work, contract price or contract time.

The exact change process varies depending on the contract being used.

Eventually, the project reaches the point where construction is substantially complete and the building can transition toward occupancy and operation.

But the work of construction administration isn’t necessarily finished.

Deficiencies, warranties, record documents, operation and maintenance information, training, final inspections and other closeout requirements still need to be addressed.

Good project closeout is what turns a finished construction project into a properly documented completed project.

These terms sound similar, but they describe different roles.

Construction administration generally focuses on administering the construction contract, interpreting the contract documents, reviewing information and evaluating the work for general conformance with the design intent and contract requirements.

Construction management generally focuses on managing the construction process itself, including areas such as schedule, cost, logistics, procurement, sequencing and coordination of the work.

The exact responsibilities depend on the project’s contracts and delivery method.

A useful way to think about the distinction is:

The architect administers the contract. The contractor manages the construction.

There are important nuances to that distinction, especially with different project delivery models.

Construction administration is a team effort.

Depending on the size and complexity of the project, the construction-phase team may include:

Each participant has different responsibilities.

One of the keys to successful CA is understanding who is responsible for what — and who has the contractual authority to make a decision.

On some projects, the project architect manages construction administration.

On others, a dedicated construction administrator or CA team takes responsibility for much of the construction-phase work.

The construction administrator becomes a central point of communication between the drawings, the consultants and what’s actually happening on site.

A typical day could involve reviewing an RFI in the morning, discussing an unexpected site condition with an engineer, reviewing shop drawings, attending a construction meeting, visiting the site and documenting a change before the end of the day.

No two days are quite the same.

That’s part of what makes construction administration challenging — and interesting.

Great construction administrators need to understand more than drawings.

They need to understand contracts, construction, communication and people.

Strong CA professionals tend to be good at:

Perhaps most importantly, they need to understand that construction keeps moving.

A technically perfect answer that arrives too late can still cause a problem.

Good CA is about providing clear, well-considered information when the project needs it.

Construction projects generate an enormous amount of information.

RFIs.

Submittals.

Emails.

Meeting minutes.

Field reports.

Changes.

Photos.

Schedules.

Payment applications.

Deficiency lists.

And behind every one of those documents is communication between people trying to get a building constructed.

An unanswered question can delay work.

A forgotten submittal can affect procurement.

An undocumented site conversation can become a disagreement months later.

A poorly written instruction can create an unintended change.

Good construction administration creates a clear path:

Question → Review → Decision → Documentation → Construction

That record becomes increasingly important as projects become larger and more complicated.

There is a phrase you’ll hear frequently in construction:

“Get it in writing.”

There’s a reason.

Construction projects move quickly, and conversations happen everywhere — on site, over the phone, in meetings, through email and inside project management platforms.

Six months later, people’s memories of the same conversation can be very different.

Good documentation establishes:

Documentation isn’t about creating paperwork for the sake of paperwork.

It’s about creating clarity.

Construction administration is the process of administering the construction contract during construction and helping evaluate whether the project is being built in general conformance with the contract documents and design intent.

It includes activities such as RFIs, submittal reviews, site visits, construction meetings, change management, payment reviews and project closeout.

In architecture, CA commonly means Construction Administration.

It refers to the architect’s services during the construction phase of a project.

A construction administrator helps coordinate and document communication between the owner, contractor and consultant team during construction.

Their work may involve RFIs, submittals, site reviews, meetings, changes, payment reviews, deficiencies and closeout.

No.

Construction administration generally relates to administering the construction contract and evaluating the work against the contract documents.

Construction management generally involves managing the construction process, including schedule, cost, logistics, procurement and coordination.

Generally, no.

Under typical architectural contracts, the architect periodically observes the work and evaluates its general conformance with the contract documents. The contractor remains responsible for construction means, methods, techniques, sequences, procedures and site safety.

The specific project contracts ultimately establish the responsibilities of each party.

Construction administration typically continues throughout the construction phase and into project closeout.

For a small project that might mean several months. For a large or complex building, construction administration can continue for several years.

Construction administration provides a structured process for answering questions, reviewing construction, documenting decisions, managing changes and maintaining the design intent as the project moves from drawings to a completed building.

Construction administration is a huge subject.

And it’s difficult to learn from drawings and contracts alone.

What the RFI? explores the real-world side of construction administration — the RFIs, shop drawings, site meetings, changes, field reviews, closeout problems and conversations that happen when a design actually gets built.
