Ever wondered why we ‘re still chasing signatures for daywork sheets like it’s 1925? Or how the construction industry ended up with this complex web of main contractors, subcontractors, and rate-based billing?

Turns out there’s a fascinating story behind how we got from medieval master builders who handled everything themselves, to today’s specialised subcontractors, and how billing clients using hourly rates, day rates, per sqm, per tonne, and other rate-based methods evolved.

Quick heads up: We’re about to trace the evolution from master craftsmen to modern subcontractors, and show you exactly how daywork sheets became the essential tool for getting paid fairly in today’s construction industry.

When One Person Ran the Whole Show

Back in medieval times, building a cathedral or castle was managed by a master builder—essentially the original general contractor, architect, and project manager all rolled into one. These weren’t just skilled workers; they were entrepreneurs who controlled entire projects from design to completion.

But here’s the interesting bit: even back then, they couldn’t do everything themselves. They needed stonemasons, carpenters, and other specialists. And they had to pay them fairly for work that couldn’t always be predicted upfront.

The Original Subcontractors

Medieval guilds were basically the original subcontractors. Master craftsmen controlled specific trades, apprentices learnt the skills, and these specialized guild members worked on projects much like modern subcontractors do today.

The Original Rate-Based Payment

Payment was often based on what was actually accomplished—not unlike today’s rate-based billing. When carving stone blocks for a cathedral, masons got paid per block completed. When laying foundations, payment was based on the area covered. This was essentially the ancestor of modern per-unit billing that many subcontractors use today.

The First Proof-of-Work System

Individual masons made marks on stones to ensure they got payment for their work—essentially creating the first “proof of work completed” documentation system. This ancient practice of marking completed work for payment is the direct ancestor of today’s digital daywork sheets that prove what work was performed and justify fair payment.

The challenge then (as now) was: how do you fairly price work when every project has unique conditions, and quality matters as much as quantity?

When Clients Started Hiring Middlemen

The big shift came during the Renaissance when wealthy clients began hiring architects as separate professionals to design buildings and manage projects on their behalf. This was the beginning of the modern system where clients don’t directly manage construction—they hire someone else to do it.

Andrea Palladio is widely regarded as the first modern architect, focusing purely on design while leaving construction to others. Suddenly, master builders found themselves dealing with an intermediary. Architects started controlling budgets, specifications, and payments. This is when construction became more contractual rather than the direct relationship between client and builder.

The Introduction of Formal Pricing

With architects managing client money, everything had to be more formal. Written contracts, detailed specifications, and systematic pricing became necessary. This is when the industry started moving away from simple “pay for what you accomplish” towards more complex pricing structures.

But complex work still couldn’t always be priced upfront. The solution? Rate-based pricing for specialist work—pay skilled craftsmen based on time, area covered, or units completed.

This created the first real distinction between:

• Contracted work: Clearly defined scope with fixed pricing

• Rate-based work: Variable scope paid according to agreed rates

The Birth of General Contractors

The Industrial Revolution in the 1800s brought massive construction projects—railways, factories, bridges—that were too big for individual master builders. This led to the emergence of general contractors: companies that coordinated multiple trades but didn’t necessarily perform all the work themselves.

From Direct Employment to Subcontracting

Initially, general contractors employed workers directly. But as projects became more complex and specialised, it made more sense to subcontract specific trades to specialists who had the right skills, tools, and experience.

A steelwork company knew steel better than a general contractor ever could. A glazing specialist understood glass installation better than anyone else. The electrical trade was becoming so specialised that it needed dedicated electricians.

By the middle of the 19th century, subcontracting became widespread because it offered:

• Specialized expertise: Each trade could focus on what they did best
• Flexible workforce: Contractors could scale up and down as needed
• Risk distribution: Specialized subcontractors managed their own trade-specific risks
• Cost efficiency: Competition between subcontractors drove better pricing

The Problem: How Do You Bill for Specialist Work?

This created a new challenge: how do you bill clients in a formal manner for specialist work that might be:

• Highly skilled (where experience and expertise matter more than time)
• Variable in conditions (where site conditions affect the work required)
• Urgent (where speed matters more than detailed quotes)
• Bespoke (where every installation is unique)

The answer was rate-based billing: charge for the actual work performed using agreed rates.

When Subcontracting Became the Norm

By the early 1900s, the construction industry had largely settled into the structure we recognise today:

• Clients hire architects and main contractors
• Main contractors coordinate the project and manage subcontractors
• Subcontractors perform specialised work using their expertise and equipment

This system worked because it allowed each party to focus on what they did best. But it created new challenges around documentation and billing.

The Birth of Modern Daywork Sheets

With multiple subcontractors on every project, main contractors and clients needed systematic ways to verify and approve work that couldn’t be easily priced upfront. This led to the development of formal daywork procedures.

Most standard forms of contract make provisions for variations to be valued on a daywork basis if the varied work cannot be properly valued by measurement. However, few standard forms describe the process for completion, authorisation or submission of dayworks.

This gap created the need for standardised daywork sheets—forms that could document:

• Who performed the work (labour and skills)
• What materials were used
• What equipment was required
• How much time was spent
• What was actually accomplished

The Standardisation Revolution

The development of standardised payment claim forms like the AIA G702 and G703 in the United States created frameworks that influenced construction documentation worldwide. These established the principle that rate-based work needed systematic documentation for client billing.

In 1888, the AIA collaborated with the National Association of Builders to produce the first nationally standardized building contract form in the US, setting the foundation for modern construction documentation practices.

But even with standards, the process remained largely manual and paper-based for decades.

What Daywork Actually Means for Subcontractors

Today’s daywork system allows subcontractors to bill clients using various rate structures:

• Hourly rates for skilled labour where expertise is the value
• Day rates for when daily productivity is more relevant than hours
• Per-unit rates (per sqm, per tonne, per linear metre) for measurable work
• Time and materials for complex work where both labour and materials vary

This flexibility exists because construction work resists simple pricing. Every project has unique challenges, site conditions, quality requirements, and time pressures.

When Subcontractors Use Rate-Based Billing

Modern subcontractors use daywork billing for various scenarios:

Planned rate-based work: High-end fitouts, heritage restorations, or specialised installations where hourly billing reflects the true value of expertise.

Variable conditions: Projects where site conditions, access issues, or material quality could significantly affect time and resources required.

Urgent work: When clients need immediate action and traditional quoting processes would cause delays.

Bespoke or complex work: Custom installations, problem-solving, or work requiring particular expertise where the value lies in the skill level.

Unexpected situations: Encountering underground services, structural issues, or other unforeseen challenges.

The Paper Problem

For decades, daywork documentation remained stubbornly manual. Dayworks processes have been very manual processes historically, with many civil and site-based companies collecting paper dayworks sheets and dockets, and reconciling them in spreadsheets, often double-handling and double-entering the data.

Subcontractors were creating documentation for clients, then re-entering the same information for their own records. Clients were struggling to read handwritten forms. Signatures were constantly being chased around sites.

Modern Digital Solutions

Today’s digital daywork solutions solve problems that paper never could:

• Professional client documentation that clearly shows value received for rates paid
• Real-time approvals from anywhere, eliminating signature chases
• Automatic calculations for all rate types (hourly, daily, per-unit)
• Instant client delivery via professional PDFs
• Complete audit trails that never get lost or damaged
• Photo documentation with timestamps proving work was performed

Your phone is more powerful than the computers that got us to the moon. Maybe it’s time we used it for something more useful than checking scores during smoko—like creating professional documentation that clearly shows clients the value they’re receiving for the rates they’re paying.

The Evolutionary Pattern

Understanding this evolution shows that every major change in construction has been driven by the same forces:

• Increasing specialisation (from master builders to specialist subcontractors)
• Complex client relationships (from direct relationships to multi-tier contracting)
• Need for flexible billing (from simple job pricing to sophisticated rate structures)
• Documentation requirements (from handshake deals to legal protection)

The Modern Reality

Today’s subcontractors operate in the most sophisticated version of this system yet:

• Higher skill requirements than ever before
• Complex regulatory environments requiring detailed documentation
• Demanding clients expecting professional service and transparent billing
• Competitive markets where efficiency and professionalism matter

The Digital Advantage

Modern digital daywork solutions aren’t just about convenience—they’re about professional survival in a competitive industry. When skilled subcontractors are in demand but clients expect professional documentation, the tools finally exist to deliver both quality work and quality billing documentation.

The journey from medieval master builders to modern subcontractors tells a clear story: skilled construction professionals have always needed fair, flexible ways to get paid for unpredictable, high-quality work.

What’s evolved is the complexity of the relationships and the sophistication of the documentation required. Where medieval stonemasons might have been paid per block, today’s subcontractors might bill per sqm, per hour, or per day – but the principle is identical.

Where guild masters negotiated directly with cathedral builders, today’s subcontractors work through main contractors for clients they may never meet – making professional documentation more critical than ever.

Your great-grandfather’s guild might have used verbal agreements and handshake deals. Your grandfather probably used carbon-copy forms and manual calculations. You’re dealing with digital systems and instant client expectations.

But the fundamental challenge remains unchanged: proving to clients that skilled work was performed professionally and should be paid for fairly.

The difference today? The tools finally exist to create professional client documentation that matches the sophistication of modern subcontracting work.
