What this is
What is a Temporary Works Approval?
What is a Temporary Works Approval?
It is the record that authorises a temporary structure, support, barrier or arrangement before it goes up, naming who designed it, whether the design was checked independently, and when it comes down. It is raised before erection and approved by engineering, and it stays open through erection, use and removal rather than closing once the structure is standing.
What counts as temporary works under this record?
The Category field names the ground it covers: scaffolding, excavation support, propping, formwork and falsework, plus an Other option for anything else that is erected to support a load or restrict access for a defined period rather than built as part of the permanent works.
Who is the Temporary Works Coordinator and why does the field matter?
It is the named person accountable for the temporary works existing safely from design through removal, distinct from the Designer who produced the calculations and the Engineering Manager who signs the approval. Naming the role is what stops erection and removal decisions defaulting to whoever happens to be on site that day.
Scope
When is a temporary works approval required?
This record is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use this template when
- A temporary structure, support, barrier or arrangement is about to be designed, erected or brought into service
- The workspace is being set up, or the register needs an entry added or retired
- You are running the Site Access and Facilities programme and this is one of its steps
- A linked record needs this one to exist: links Permit to Work and Interim Control
- Existing temporary works are being re-inspected, modified or extended past their planned removal date
Do not use it for
- Access Request Record, which requests and approves access for a person to an area or a system, with the justification and an end date.
- Visitor Log, which records who was on site, when, why and who was responsible for them.
- PPE and Locker Issue Record, which records what personal equipment was issued to whom, in what size, and when it is due for replacement.
- Permit to Work, which authorises entry into a hazardous task or space for a defined window, separate from the structure itself.
- Anything outside KnowOps, which belongs in the workspace that owns that process
Compliance mapping
Which OSHA 1926 Subpart L requirements does this satisfy?
OSHA 1926 Subpart L governs scaffolds specifically, with 1926.451 setting general requirements and 1926.454 covering training; this record applies that same design-check-erect-inspect discipline across every Category the field allows, not scaffolding alone.
| Clause | Requirement | Where it lands |
|---|---|---|
| OSHA 1926.451(a) | Scaffolds and their components must support their maximum intended load with a defined safety factor | Design |
| OSHA 1926.451(a) | The supporting surface and foundation must be capable of carrying the loaded structure without settling or displacement | Design |
| OSHA 1926.451(b) | Platforms and working surfaces must be fully planked and constructed to the design before use | Erection |
| OSHA 1926.451(f)(3) | A competent person must inspect the structure before each work shift and after any occurrence that could affect its integrity | In service and removal |
| OSHA 1926.454(a) | Employees who erect, dismantle or inspect scaffolds must be trained by a competent person | Erection |
| OSHA 1926.451(a) | Any change to a structure's load path or configuration must be re-assessed against the original design basis | In service and removal |
| OSHA 1926 Subpart L | Retain records showing the structure was inspected, approved for use and confirmed removed, not just erected | Outcome |
What it does not cover
- Loads Calculated, which is marked No or left blank, meaning the temporary works were designed without knowing what they actually need to carry.
- Design Checked Independently, which is skipped for anything above Low risk, meaning a single point of failure in the design has never been reviewed by anyone but the person who produced it.
- Inspected At The Defined Frequency, which lapses once the works are in service, meaning a structure approved once is being treated as verified for the whole of its life.
- Removal Sequence Planned and Removed By The Planned Date, which are both required at closure, meaning works taken down under no planned sequence were taken down under no sequence at all.
- Nothing Left Relying On It, which is marked Yes without checking downstream trades, meaning removal that leaves another system still bearing on the temporary support is not really removal.
Global
Temporary Works Approval requirements by country
OSHA 1926 Subpart L is the instrument named on this template, but it only fully covers the Scaffolding value of Category; the other categories, and the procedural model behind the fields themselves, come from elsewhere.
OSHA 1926 Subpart L, esp. §1926.451
A scaffold-specific standard, legally enforceable on covered US construction sites, setting load, platform and inspection requirements
Where Category is Scaffolding, this record's Design and Erection checks map directly onto Subpart L; where Category is Excavation support, Propping, Formwork or Falsework, the applicable OSHA provisions sit in different subparts and this template is doing more work than its named basis covers.
BS 5975 — Code of practice for temporary works procedural management
The named source of the Designer, independent design check and Temporary Works Coordinator model used across the construction industry
The field structure here, a named designer, an independent check, a named coordinator, is BS 5975's procedural model, not an OSHA requirement; teams running formally to BS 5975 should treat this record as the coordinator's register rather than a substitute for the procedure itself.
General falsework and formwork collapse investigation findings
A recurring pattern across major construction collapses, where undesigned load paths, unchecked ground conditions or an unowned removal are found afterward, not beforehand
Ground Or Support Conditions Assessed and Wind Or Weather Considered exist because those two conditions are the ones most often found absent after a falsework or formwork failure, not because a checklist demanded them.
How to complete it
How to complete a temporary works approval, step by step
Filling in every field is the easy part. The judgement calls below are what decide whether the approval actually stands up when the structure is still there longer than planned, or is asked to carry more than it was designed for.
Scaffolding, Excavation support, Propping, Formwork and Falsework carry different design and inspection regimes. Choosing Other to avoid the harder Design section questions is the judgement call worth watching for.
Design Checked Independently answered Yes needs to mean a second competent person who wasn't part of the original design looked at the calculations, not the same designer reviewing their own sketch a day later under a different hat.
Risk Level should reflect what happens if the temporary works fail, whether nothing is beneath it or a live process or occupied area is, not simply how complicated the structure was to erect.
Temporary Works Coordinator is named at Header. The judgement call at closure is whether that same person confirmed Removed By The Planned Date and Nothing Left Relying On It, or whether closure was signed by whoever was available.
What auditors find
Most common temporary works approval findings
These are the failure patterns that actually show up in Temporary Works Approval records once the structure has been standing a while, not the ones a checklist would predict.
| Finding | Clause | What fixes it |
|---|---|---|
| Category is recorded as Other for structures that are clearly excavation support or falsework. | OSHA 1926 Subpart L | Tighten the Category options and require a written justification whenever Other is selected. |
| Design Checked Independently is Yes with Design Reference left blank, so there is nothing on file to check against. | OSHA 1926.451(a) | Make Design Reference mandatory whenever Loads Calculated or Design Checked Independently is answered Yes. |
| Inspected At The Defined Frequency is answered once at erection and never revisited while the works remain standing. | OSHA 1926.451(f)(3) | Schedule a recurring prompt tied to the stated inspection frequency instead of leaving it as a single-answer field. |
| Wind Or Weather Considered is marked N/A for an external scaffold or exposed falsework. | OSHA 1926.451(a) | Block N/A on this field whenever Category is Scaffolding, Formwork or Falsework. |
| Removed By The Planned Date is No with no follow-up reapproval reference anywhere in the record. | OSHA 1926 Subpart L | Require a new reference whenever Removed By The Planned Date is No, mirroring the reapproval discipline Not Modified Without Reapproval already applies to structural changes. |
| Any Failure Or Movement is marked N/A for works that were plainly in service and inspected, rather than for works never brought into use. | OSHA 1926.451(f)(3) | Restrict N/A on this field to works that were never brought into service, not to works that simply had an uneventful life. |
Case in point
Case in point: the falsework nobody signed off twice
Falsework was erected for a concrete pour. Loads Calculated and Ground Or Support Conditions Assessed were both Yes, the design was checked independently, and Approved For Use read Yes. The pour went cleanly and the site moved on to the next block.
Removed By The Planned Date sat blank for weeks afterward, because the Temporary Works Coordinator who had approved erection had rotated off site and nobody currently there owned the removal. The falsework stood as de facto permanent formwork, holding up nothing anyone on site could actually name.

From a document you fill in to a programme that runs itself
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the Temporary Works Approval register against Site and Site ID, flags anything past Removal Planned, and keeps the Permit to Work and Interim Control links live.
Watches the Design and Erection checks for anything scored below par, and makes sure Inspected At The Defined Frequency doesn't quietly stop once a structure is signed off for use.
Tracks Designer competence and whether Design Checked Independently reflects a genuine second reviewer, so contractor-supplied designs don't get waved through on trust.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.

Temporary Works Approval definitions and key terms
- Temporary works
- A structure, support, barrier or arrangement erected for a defined period to support a load or restrict access during construction, rather than forming part of the permanent works.
- Temporary Works Coordinator
- The person named as accountable for temporary works from design through removal, distinct from the designer who produces the calculations and the manager who signs the approval.
- Falsework
- A temporary structure used to support formwork, plant or the permanent structure itself while it is being built, typically removed once the permanent structure can carry its own load.
- Propping
- Temporary support installed beneath or against an existing structure, often during alteration or demolition, to carry load the structure can no longer safely bear alone.
- Independent design check
- A review of a temporary works design carried out by a competent person who was not involved in producing the original design, used to catch errors a single designer would not.
FAQ
Frequently asked questions about temporary works approval
Does every scaffold or prop on site need its own Temporary Works Approval?+
Anything erected to support a load or restrict access for a defined period, across every Category value the field allows, should go through it, because the Design and Erection checks are what stop a routine-looking structure from being the one nobody re-checks.
What happens if OSHA 1926 Subpart L doesn't actually cover the Category chosen?+
Subpart L governs scaffolding directly; Excavation support, Propping, Formwork and Falsework sit under different OSHA provisions or under a procedural standard such as BS 5975. This record still applies, but the applicable law behind it changes with Category.
Why does this link to Permit to Work instead of covering the task itself?+
This record approves the structure existing; a Permit to Work authorises the hazardous task carried out on or near it, for a defined window. Erection, use and removal of temporary works are often each covered by a separate permit referenced here.
Who is accountable if temporary works are never removed?+
The Temporary Works Coordinator is named at Header specifically so that accountability doesn't default to whoever built or last inspected the structure. Removed As Planned and Nothing Left Relying On It are the fields that prove the loop was closed, not just opened.
Is a Design Reference required for every category of temporary works?+
It is not marked required on the field itself, but Loads Calculated and Design Checked Independently being Yes with no Design Reference on file means there is nothing to check the erected structure against later, which defeats the point of an independent check.
Can inspection frequency be reduced once the works are signed off for use?+
Signed Off For Use closes the erection phase, but Inspected At The Defined Frequency is a separate, ongoing field precisely because a structure's condition can change after erection through weather, load or nearby work, regardless of how clean the initial sign-off was.
