Light steel fabrication and erection checklist: how to use Table 10.1

QSteelCAD · RENMAE

Short answer

Table 10.1 of the 2027 light steel regulation inspects fabrication and erection under eight headings: material, section conditions, conformity to the project, erection, panel systems, floors, fire and the design report. Each item is marked in the columns acceptable, not acceptable and remarks. The list checks conformity both to the structural project and to material properties.

Key points

  • Table 10.1 consists of eight headings and 24 items.
  • Each item has acceptable, not acceptable and remarks columns.
  • The list also asks for the calculation report: item 8.1.
  • Strap tension and brace integrity are not separate items in the list; they should be added to the project.
  • Some of the checks can be done in the factory and some during erection.

Introduction

In light steel construction, most defects end up hidden under the sheathing. So when a check is made matters at least as much as what is checked. Section 10.3 of the 2027 light steel regulation requires Table 10.1 to be used to check on-site fabrication and erection against both the structural project and the material properties. The introduction to Section 10 states that members whose fabrication is complete are shipped to site only after they are documented as defect-free and flawless within the defined tolerances.

What is in Table 10.1?

NoCheck itemQuestion asked
1.1Steel gradeDoes the steel comply with TS EN 10346 and TS EN ISO 1461?
1.2Quality certificateHas the mill test certificate of the steel sheet been checked?
1.3Galvanized coatingWas the coating amount selected according to Annex Table 1?
1.4Screws and fastenersWere the conditions in Section 2 met for the screws?
1.5Holes made on siteWere holes and cuts repaired with zinc-based paint?
2.1Profile dimensionsDo the flange, web and stiffener dimensions meet the limits?
2.2Profile bend radiiDo the inside bend radii meet the limits?
2.3Flange widthDoes the flange width meet the minimum limits?
3.1Production of profilesWas the accuracy of the profiles checked against the project?
3.2Checking of sectionsWere shape, dimensions and surface flatness compared with the project?
3.3Screw checkDo the diameter, position and frequency of the screw holes conform to the project?
4.1Placement of membersAre positioning and alignment correct?
4.2ConnectionsWere the stated number and type of screws used in the connections?
4.3Anchor installationWere the anchors placed at the stated diameter and spacing?
4.4Connection gusset platesWere the gusset plates fastened with the stated number and size of screws?
5.1Sheathed panel layoutIs the stud spacing at most 625 mm and are the studs ≥ 0.9 mm?
5.2Panel frameAre the top and bottom tracks of profiles ≥ 0.8 mm?
5.3Screw connectionsWere the sheathing panels screwed on all four edges in line with the project and TBDY?
5.4Horizontal bridgingIs the bridging placed at no more than half the panel height?
6.1Floor joistsAre the joists of the section and spacing in the project?
6.2Web stiffenersWere stiffeners and connection members placed in sufficient proportion?
6.3Floor connectionsWere the web and connections fastened with screws in line with the project?
7.1Fire designWere the conditions in Section 11 met?
8.1Design reportIs the calculation report attached?

The text is simplified from the regulation table. When preparing your inspection form, use the official text of the table as the basis.

Who should do the checks, and when?

StageItemsWhy here
When the coil arrives1.1, 1.2, 1.3Wrong material is stopped before it enters the line
At first-piece production2.1, 2.2, 2.3, 3.1, 3.2, 3.3Line setup is verified on the first piece
While the panel is assembled in the factory1.4, 4.2, 5.1, 5.2, 5.4Screws and spacing are visible before sheathing
At foundation and anchors4.3, 4.4A missed anchor is noticed before the panel arrives
At erection4.1, 5.3, 6.1, 6.2, 6.3Members are checked in place
Before closing in1.5, 7.1, 8.1The final check is made before the sheathing is closed

This breakdown is our suggestion, not the regulation's. Adapt it to your factory's workflow. What matters is that each item is asked at a moment when you can still correct a defect.

What should be added to the list for bracing?

Table 10.1 is a general list and has no separate item for bracing. For braced panels it is useful to add these questions:

  • Is the brace placed as a single continuous member between the top and bottom track?
  • Are the brace ends connected to the studs as well as to the track?
  • Are the straps tight, and were they fixed with the panel plumb?
  • Is the strap on the correct face, and is there a second strap in a double-sided detail?
  • Is the brace uncut, undrilled and unshifted?
  • Is the chord stud pack as in the project?
  • Does the tension anchor line up with the chord stud?
  • Does the upper-storey panel sit on the lower-storey panel?
  • Are the temporary props in place, and has the removal stage been defined?

How is the list documented?

Every row on the form should record three things: the result, who checked, and the date. On a row marked not acceptable, the remarks column must not be left empty; what was done and who approved it should be written. To show the inside of walls that are later closed, it also helps to attach a photo matched to the panel ID.

Where does QSteelCAD fit into this list?

Before writing the production file from the model, QSteelCAD runs minimum length, clash and model checks. These checks help catch some of the errors under items 3.1 and 3.3 before the file goes to the machine. Material, screw, anchor and erection checks, however, remain in human hands in the factory and on site. The program does not mark any item acceptable on your behalf.

Frequently asked

Is Table 10.1 mandatory?

Section 10.3 of the 2027 light steel regulation states that Table 10.1 must be used to check on-site fabrication and erection. The regulation takes effect on 1 January 2027.

Who signs the list?

The table does not define a signature field. Inspection responsibilities are determined under the building inspection provisions of Article 4 of the regulation. It helps to have a responsible person and date field on your company's form.

How is a sheathed wall checked?

The check must be made before the sheathing is closed. For connections that cannot be seen afterwards, photos and records tied to the panel ID should be kept.
