Phantom Orders and Paper Trails: Navigating Instructions Under SIA

Phantom Orders
14 Oct

Summary: In construction, an instruction can start with a conversation on site, a marked-up drawing, or an email — but when payment, variations, or disputes arise, what matters is often what can be proved. Under the SIA Building Contract, the distinction between an Architect’s Direction and Architect’s Instruction, together with the requirements for written confirmation, can have significant consequences for contractors, quantity surveyors, and architects. This article looks at how to manage instructions, maintain a reliable paper trail, and reduce the risk of claims becoming difficult to substantiate.

When an Instruction Exists Only in Someone’s Memory

Construction projects move quickly. A contractor may be told during a site meeting to shift a wall, change a finish, investigate an unexpected condition, or proceed with additional work. Everyone may understand what needs to happen — until the variation claim arrives months later.

This creates a familiar problem: Who instructed the work, when was it instructed, what exactly changed, and where is the evidence?

“Under the SIA Building Contract 2016: Clause 1 deals specifically with Architect’s Directions and Instructions. The contract distinguishes between these two forms of order and provides procedures for written and verbal directions and instructions.”  – Singapore Institute of Architects

For project teams, the lesson is straightforward: an instruction should not disappear into the daily noise of construction.

Direction vs Instruction: Why the Difference Matters

A useful way to think about the distinction is:

Issue Architect’s Direction Architect’s Instruction
Basic purpose Often concerned with compliance, methods or other matters within the contract May require changes to the Works or other instructed actions
Potential payment impact May not necessarily create entitlement to additional payment Can have consequences for valuation or compensation
Documentation Should be recorded clearly Should be recorded clearly, particularly where cost or time may be affected
Main risk Disagreement over what was required Disagreement over scope, valuation, entitlement or timing

The precise effect depends on the contract wording and circumstances. The Singapore Academy of Law has noted that under the SIA 2016 form, the distinction between Directions and Instructions can become important when determining whether additional payment or compensation is involved.

Verbal Instructions: Where the Paper Trail Starts

The most dangerous instruction may be the one everyone remembers differently.

The SIA 2016 provisions recognise that verbal Directions or Instructions may occur, but set out a process for written confirmation. The contractor is required to request written confirmation within the specified period, while the Architect is required to respond within the contractual timeframe. Without the required confirmation, compensation may be affected.

This is where construction documentation becomes more than administration.

A practical approach is to record:

  • Date and location of the instruction
  • Person giving the instruction
  • Exact work requested
  • Relevant drawing or specification
  • Whether the work changes the original scope
  • Likely cost impact
  • Possible extension of time impact
  • Labour, plant and materials affected
  • Photographs or site records
  • Subsequent written confirmation

The principle is simple: If it could affect money or time, record it.

Building the Paper Trail: From Instruction to Claim

A strong paper trail connects the instruction to its consequences. It should allow someone who was not present on site to reconstruct what happened. If a contractor receives an instruction to replace a specified material, the record should ideally identify the original requirement, the revised requirement, when the change was instructed, what work was carried out, and the quantities involved.

This is particularly important for quantity surveyors, who may later need to assess whether work qualifies as a variation, establish quantities, and support the valuation with contemporaneous evidence.

Singapore’s BCA also emphasises proper maintenance of site records. Its guidance specifically identifies site record books, approved plans and amendments, and records of instructions as documents that should be maintained for relevant structural works.

What Happens When the Paper Trail Is Missing?

The absence of paperwork does not automatically answer every contractual dispute. Singapore case law has recognised that contractual requirements concerning written variations can interact with principles such as waiver or estoppel in appropriate circumstances.

In practice, missing records can make it harder to establish:

  • Whether an instruction was actually given
  • Whether it was authorised
  • Whether it changed the contractual scope
  • The quantity of additional work
  • The actual cost incurred
  • Whether the work caused delay
  • Whether contractual notice requirements were followed

Other standard forms take a similarly documentary approach. For example, Singapore’s PSSCOC requires certain instructions to be in writing while also providing a mechanism for oral instructions to be confirmed in writing. Its claims provisions also emphasise notices and contemporary records.

Better Instruction Management: A Practical Checklist

Good contract administration does not mean creating paperwork for its own sake. It means creating enough evidence to tell the project’s story accurately.

Project teams can adopt five basic habits:

  1. Confirm verbal instructions quickly.
  2. Reference the relevant drawing, specification or contract clause.
  3. Separate instructions from assumptions.
  4. Record cost and time consequences as they emerge.
  5. Keep documents together so the instruction can be traced through to valuation and payment.

The goal is not to predict every future dispute. It is to make the project’s records understandable if a dispute does occur.

Conclusion

On a busy construction project, instructions can pass through meetings, phone calls, drawings, emails and site conversations. The real problem begins when those fragments no longer tell the same story.

Under the SIA Building Contract, careful handling of Architect’s Directions, Architect’s Instructions, written confirmations and supporting records can help project teams establish what was instructed and what followed.

The strongest paper trail is therefore not simply a stack of documents: it is a clear chain connecting the instruction, the work, the cost and the time impact. For contractors, quantity surveyors, consultants and architects, that chain can become essential when a routine site instruction eventually turns into a construction claim.

 

Frequently Asked Questions

What is an Architect’s Instruction under an SIA contract?

Answer: An Architect’s Instruction is an order issued by the Architect under the relevant SIA contract. Its exact scope and contractual effect depend on the edition and terms of the contract being used.

Can a verbal instruction be valid under the SIA Building Contract?

Answer: The SIA 2016 form contains provisions dealing with verbal Directions and Instructions and provides a process for requesting written confirmation. Contractors should follow the specific procedure and time limits in their executed contract.

Why are written instructions important for variation claims?

Answer: Written instructions help establish what was requested, when it was requested and whether the work falls within the contractual mechanism for a variation. In the SIA 2016 form, the written requirement can be particularly significant to claims for payment or compensation.

What records should a contractor keep after receiving an instruction?

Answer: Useful records include the instruction itself, drawings, photographs, site diaries, measurements, delivery records, labour records, quotations, invoices and correspondence relating to cost or delay.

Does the Architect’s label of “Direction” or “Instruction” settle the matter?

Answer: Not necessarily. The SIA 2016 form contains provisions concerning the classification of orders, and the contractual effect depends on the relevant clauses and circumstances.

Is this issue unique to Singapore?

Answer: No. Written instruction and variation procedures are common features of construction contracts internationally. However, the exact requirements differ between contract forms and jurisdictions.
