Hollow Core Plank Layouts
Floor and roof plank marking plans showing unit identification, orientation, span direction, grid references and setting-out dimensions.
Precast concrete / Floor & roof systems
Precast Hollow Core Slab Detailing Services
Coordinate precast hollow-core plank layouts, fabrication information and erection documentation around approved structural designs. We support precast producers, structural consultants and construction teams with clear plans, bearing details, opening coordination and revision-controlled drawing packages.

Conceptual graphic only; not a fabrication drawing or engineering approval.
Detailing capabilities
Clear hollow-core production and installation documentation
Our documentation scopes are coordinated with the project engineer, precast producer and applicable supplier standards. Each deliverable is based on the latest approved drawings and project-specific instructions.
Individual Unit & Shop Drawings
Plank piece drawings showing approved unit geometry, length, end conditions, recesses and relevant production annotations.
Bearings, Seats & Connections
Documentation of approved support interfaces, bearing lengths, connection plates, ties and edge restraint details for coordination.
Openings & Service Coordination
Plans identifying openings, block-outs, penetrations, edges and MEP interfaces, with unresolved structural impacts escalated for review.
Reinforcement & Cast-In Details
Drawings and schedules for specified reinforcement, topping interfaces, grout details and cast-in components where applicable.
Erection Plans & Schedules
Unit marking plans, plank schedules, setting-out notes, delivery identification and revision-aware erection documentation.
Typical project outputs
Deliverables arranged for production and field coordination
We structure files around the agreed issue list and supplier requirements, distinguishing drawing preparation from the engineering checks and releases that must be performed separately.
- Floor and roof hollow core plank arrangement plans
- Individual plank shop or piece drawings and unit marks
- Plank dimensions, elevations, orientation and opening references
- Bearing, edge, closure, keyway and grouting details
- Specified reinforcement and cast-in item schedules
- Precast piece lists, marking registers and quantity takeoffs
- PDF and DWG drawing packages with change tracking
Drawing workflow
From approved layouts to controlled drawing releases
Each phase is structured to surface missing information before the package reaches a precast production or installation milestone.
Review design inputs
Confirm slab zones, grids, supports, plank product requirements and identified openings or conflicts.
Build the drawing set
Prepare plank marking layouts, individual piece details, schedules and interface documentation.
Coordinate comments
Track engineering, plant, architectural and MEP comments; resolve information gaps through defined approvals.
Issue approved revisions
Deliver the requested drawings, schedules and issue register following the project’s agreed release process.
Technical responsibility
Hollow-core detailing remains tied to verified structural design
Plank capacity, prestressing, end bearing, camber, openings, fire performance, diaphragm action, handling and temporary stability all depend on project-specific engineering decisions.
Our drawings communicate approved information and flag conflicts. Engineering analysis, strand design, changes to manufactured units, lifting plans, field cutting and local code compliance require authorization by the engineer of record, the precast supplier and other designated responsible parties. Drafted details are not automatically released for fabrication or site use.
Frequently asked questions
Hollow core slab detailing FAQs
What drawings are included in hollow core slab detailing?
Depending on the agreed scope, documents can include plank layout plans, unit mark drawings, opening and recess details, bearing and connection details, erection plans and schedules.
Can openings and service penetrations be shown in the drawings?
Yes. Openings and penetrations can be coordinated from approved architectural and MEP information, but cutting locations, strand interference and the resulting structural adequacy require the responsible designer and precast supplier’s approval.
What information is needed to begin?
Current architectural and structural plans, grid and level information, approved plank sizes and span direction, bearing specifications, opening schedules, precast supplier requirements and relevant design notes.
Are prestressing design and lifting approvals included?
Not automatically. Strand patterns, load capacity, camber, lifting, bearing adequacy and temporary stability must be verified by qualified project engineers and the responsible precast supplier under a separately agreed engineering scope.
