FAQ — questions that come up on every project.
Questions we get asked on almost every project — about what goes into a submittal, where the scope boundary sits, what QC records look like, and what happens after the panels leave the factory.
What goes into a submittal — and what gets revised.
What goes into a submittal pack?
It depends on the project stage, but most submittal packs include a drawing index, scope summary, revision log, interface notes, and QC evidence references. For a consultant reviewing panel thickness, the relevant items are different from what a procurement team needs before placing an order. The structure follows the role and the question being answered.
What can I see before submitting project requirements?
The public pages — Resources, Application Notes, Common Problems, Delivery System — cover pack structure, interface logic, thickness methodology, and delivery sequence. Project-specific drawings, controlled QC records, and request-linked materials are only available after project intake via Submit Requirements.
How are drawing revisions tracked?
Each revision is indexed and tied to the review request it belongs to. When a consultant raises a comment that changes a dimension or interface condition, the updated drawing gets a new revision index and the change is logged. Review teams should confirm which revision they are working from before marking a comment as resolved — this is the most common source of misalignment in multi-round reviews.
Where our scope ends and the site scope begins.
What does PG Acrylic supply — and what is outside scope?
We supply the cast PMMA acrylic panels and the project documents that go with them: drawings, QC records, packing guidance, and handover support. Civil work, steel framing, MEP connections, silicone application, and site installation are outside our supply scope unless specifically agreed. The boundary needs to be confirmed in writing before fabrication — scope gaps discovered after panels arrive on site are expensive to fix.
What interface information needs to be confirmed before fabrication?
Four things need to be confirmed before we can finalise panel dimensions: the frame rebate geometry, the support condition on each edge (two-sided, three-sided, or four-sided), the silicone or gasket specification, and access conditions for installation. If any of these are unresolved when fabrication starts, the panel may need to be remade. Interface issues discovered on site are the most common cause of rework on viewing panel projects.
Why does the review path depend on project role?
An EPC contractor needs scope boundaries confirmed before fabrication. A structural consultant needs calculation evidence before sign-off. A procurement team needs QC records before payment. An installer needs lifting and handling guidance before the panels arrive. The same project, four different questions — sending everyone to the same page wastes time. Use By Role to start from the right place.
What the QC records cover — and what to check when the panels arrive.
What QC records come with the panels?
Standard QC records include raw material inspection reports (SGS for each Mitsubishi Chemical MMA batch), dimensional check records, visual inspection sign-off, and panel ID mapping. For public aquarium and oceanarium projects, fabrication inspection records and third-party inspection reports are also available. The specific set depends on project type and what was agreed at intake.
How are panels packed for shipping, and what lifting equipment is needed on site?
Panels are packed using the 3F system: protective film on both faces, thick foam padding, and an angle iron frame to handle impact during long-distance shipping. For lifting on site, the method depends on panel size and weight — larger panels need spreader beams or suction lifters, not slings around the edges. Lifting requirements should be reviewed before the panels leave the factory, not after they arrive.
What should be ready on site before the panels arrive?
Five things: access route confirmed for the delivery vehicle, lifting equipment on site and tested, storage area prepared (flat surface, no point loads on the panel edges), frame or channel ready to receive the panel, and the installation team briefed on handling sequence. Panels damaged during site receipt because the site wasn't ready account for a significant share of after-delivery problems.
SR-ID requests, submission inputs, and who this page is for.
When does a project need to go through Submit Requirements?
When you have specific dimensions, water depth, and support conditions that need a real answer — not a range from a reference table. If you're quoting a client, confirming a thickness for a drawing, or preparing for a structural review, that's when to submit. If you're still comparing application types or checking whether we've done similar projects, start with Resources or Installed Projects first.
What information do I need before submitting?
The more you can send, the faster the response. Minimum useful inputs: application type (pool wall, aquarium window, tunnel, etc.), opening dimensions, water depth, and your role on the project. Helpful additions: CAD drawings, frame or channel details, support condition, and any constraints on panel thickness or weight. If you only have partial information, submit what you have — we'll identify what's missing.
