“Project Management for Architecture Studios: Fees, Phases and Control”

Why do architecture projects lose money even when the fee looks reasonable?

project management for architecture is a key topic in modern project management and teamwork. Because the fee is negotiated as a percentage of construction cost while the cost is incurred in hours, and the two are only loosely connected. A 6% fee on a simple warehouse and a 6% fee on a heritage renovation with a difficult client and a slow planning authority buy very different amounts of work.

Four structural pressures do the damage:

1. Fee competition compresses the percentage. Public and developer-led work frequently goes to the lowest compliant bid, which forces studios to absorb risk they never priced.
2. Scope grows after signature. Client-led changes to the brief, extra design options, and planning-driven redesigns are normal, but they are frequently performed without an additional-services instruction.
3. Consultant coordination is underestimated. Structural, mechanical, and specialist coordination in technical design consumes far more hours than the fee schedules of a decade ago assumed.
4. Construction phase drags. A project that runs eight months late extends site attendance, submittal review, and RFI response — all fixed-fee work with a long tail.

None of these is a design failure. All of them are planning and control failures.

What phase structure should the plan follow?

Use the structure your contract and jurisdiction use, then map it to a single internal stage list so that hours, invoices, and deliverables share one code. Mixing two systems in one project is how fee reconciliation becomes impossible.

The percentages are a planning benchmark, not a rule: contracts, procurement routes, and project complexity shift the split significantly. What matters is that the studio writes its own distribution into the fee model and then compares actual hours against it every month.

> Note on stage naming: RIBA’s 2020 Plan of Work replaced the older alphabetical stages (A–L) with eight numbered stages and added a sustainability-focused “strategic definition” stage. If your contracts still reference the older letters, map them explicitly in the appointment document rather than relying on memory.

How do you convert a percentage fee into an hour budget?

Multiply the construction value by the fee percentage, subtract any reimbursables and subconsultant allowances, then divide by the blended hourly rate implied by your target multiplier. That final number is the capacity you have actually sold.

Worked example for a $4.2 million project at 8%:

• Fee: $4,200,000 × 0.08 = $336,000
• Less reimbursables (printing, travel, model costs): $9,000
• Less specialist consultants carried in the fee: $27,000
• Net architectural fee: $300,000
• Blended charge-out rate: $108 per hour
• Available hours: $300,000 ÷ $108 = 2,778 hours

Now distribute those hours by stage, using the table above:

The immediate insight: 611 hours spread across nine months of construction is 68 hours a month, or roughly 16 hours a week of site and submittal work. If the studio assigns that phase to a project architect who is also running two other jobs, the hours will not be found, and the overrun will be absorbed silently.

What blended rate should you use?

Calculate it from payroll, not from aspiration: total salary cost including employer taxes and benefits, divided by billable hours at target utilization, multiplied by your target multiplier. A studio paying $85,000 fully loaded for 1,450 billable hours has a direct cost of $58.60 per hour; at a 2.8 multiplier the break-even charge-out rate is $164. If the market will only bear $108, the studio needs either a lower salary band, higher utilization, or fewer non-billable services — and it needs to know that before signing.

How do you staff a project so the hours actually exist?

Staff against a resource histogram, not against a list of names. A histogram shows, week by week, how many hours each role is required; comparing it with available capacity reveals the month where the project collides with everything else.

For the example above, the first six months need:

Add the rows: 1,514 hours in six months, or 252 hours a month — six and a half full-time equivalents of design capacity in the peak months. If the studio has three architects, either the programme extends or another project slips. Both are legitimate decisions; discovering it in month four is not.

Three staffing rules hold up in practice:

• One named project architect owns the hour budget. Principals approve, but the PA defends it week to week.
• Protect a 10% contingency inside the fee, not outside it. Unallocated contingency gets consumed by the first awkward client request and then becomes invisible.
• Cap concurrent projects per PA at two major or three small. Beyond that, site attendance and coordination both degrade, and the cost appears later as rework.

How does change control work without damaging the client relationship?

Frame it as scope clarity rather than as billing. The studio that says “that is a change and here is the cost” in week two is easier to work with than the one that absorbs three changes and then surprises the client with a large invoice at handover.

A workable additional-services process has five steps:

1. Log the request the same day, in writing, in a change register with a number.
2. Assess impact in hours and programme, using the same stage rates as the original fee.
3. Issue a variation notice with a fixed price or a time cap, and an expiry date.
4. Get written approval before any work beyond the original scope begins.
5. Update the hour budget and the invoice schedule in the project plan, not in a separate spreadsheet.

Example: a client asks for three additional facade options during spatial coordination. The studio estimates 45 hours of project architect time and 20 hours of visualisation. At $145 and $95 per hour respectively: (45 × 145) + (20 × 95) = $6,525 + $1,900 = $8,425. If the studio absorbs it, that is 2.8% of a $300,000 fee gone on one request — and requests of that size typically arrive four or five times on a project this scale.

What if the client refuses to pay for changes?

Then the studio chooses between two documented options: deliver the original scope and record the refused request, or deliver the extra work as a written concession with the cost shown as a fee reduction. The second option is sometimes commercially right — but only when it is recorded, because an unrecorded concession teaches the client that scope is free.

Why is construction administration the phase that breaks the fee?

Because it is the longest phase, it is driven by someone else’s schedule, and its workload is invisible until it arrives. Site queries, submittal reviews, sample approvals, and inspections all arrive in unpredictable batches, and each one interrupts design work on the next project.

Practical controls:

• Budget CA hours monthly, not as a lump. For the example, 611 hours over nine months gives a monthly allowance of 68 hours; track it against actuals every month.
• Set a service-level agreement for RFI response — commonly three to five working days for routine queries, 24–48 hours for safety-critical ones — and publish it in the appointment.
• Charge for repeat site visits beyond an agreed number. Unbilled extra visits are the single most common hidden cost in CA.
• Review submittals in batches with a fixed weekly slot rather than reacting to each arrival.

A CA phase that runs 30% over budget on a $300,000 fee consumes an extra 183 hours, or roughly $19,800 at a $108 blended rate. On a studio running six projects, that is more than a junior salary.

What should a studio track weekly and monthly?

Weekly operational numbers keep projects out of trouble; monthly financial numbers keep the practice solvent. Both belong in one review, not two.

Earned value deserves a plain-language version for studios: for each stage, ask what percentage of the fee for that stage has been earned by deliverables issued, then compare it with the percentage of hours spent. A project that has spent 60% of its technical design hours and issued 40% of its packages is behind, and no amount of optimism at the next client meeting changes that arithmetic.

A cash-flow example

Studios fail on cash, not on profit. On the $336,000 fee with monthly invoicing at 45-day terms:

• Monthly billing: $336,000 ÷ 18 months = $18,667
• Cash arrives 45 days after invoice, so the studio funds roughly 1.5 months of work
• Direct staff cost for the project: 2,778 hours × $58.60 = $162,790, or $9,044 per month
• Peak funding requirement: about $13,600 at any moment

Add a client who pays at 75 days and the requirement roughly doubles. That is why debtor days belong on the same dashboard as utilization: a profitable project with slow payment still strains payroll.

What are the common mistakes in architecture project management?

• Pricing from a competitor’s percentage instead of from your own hour model.
• No exclusions schedule. Unclear exclusions become free work.
• One person owning both design and commercial control with no weekly check.
• Treating the programme as fixed while scope moves. Either the date, the fee, or the scope has to give.
• Under-resourcing technical design to keep the concept team intact, then paying for it in coordination errors on site.
• Invoicing on milestones with no link to hours, so an early overrun stays hidden until the final account.

What are the trade-offs studios actually face?

• Fixed fee vs percentage fee. Fixed fees suit well-defined scopes; percentage fees self-adjust when construction costs rise but reward slow delivery with nothing.
• In-house vs outsourced technical documentation. Outsourcing lowers fixed payroll but reduces control over quality and coordination, which is where the largest claims originate.
• Fewer, larger projects vs many small ones. Larger projects improve utilization but concentrate risk; a single delayed commission can empty the pipeline.
• Full CA service vs limited site attendance. Reducing CA visits cuts cost but shifts risk to the client and often to the studio’s professional indemnity insurer.

How does Doitify fit an architecture practice?

Doitify is a project and operations platform rather than a BIM or practice-management system. Studios use it for the layer that design tools do not cover: a board per commission with stages mapped to RIBA or AIA phases, an hour budget per stage with actual hours imported weekly, a change register with approval status, and a dashboard combining utilization, debtor days, and open RFIs. The practical benefit is that the fee reconciliation happens monthly instead of at final account. Transparency note: this is our own product; the same structure works in a spreadsheet, and the discipline matters far more than the tool.

Conclusion

Project management for architecture studios comes down to a short chain of commitments: convert the fee into hours, distribute those hours across the phase structure, staff the peak months honestly, log every scope change before doing the work, and reconcile hours against fee earned every month.

Do that and the studio can still take competitive commissions. Skip it and the practice finances its clients’ design changes out of its own payroll, one absorbed variation at a time.
