Composite
construction.

Steel and concrete, coordinated around the needs of the building. Explore the floor connections and the wider structural system.

Composite floor interfaces, supporting concrete elements and coordinated steel-to-concrete connections. RCC foundations, frames and slabs remain part of the wider building discussion. See how the package connects to our industrial EPC approach.

Materials with purpose

The structure follows the building

Concrete knowledge. Open thinking. The right material, in the right place.

SEED’s industrial and aviation experience includes reinforced-concrete superstructures, foundations and floor slabs. That concrete knowledge stays central when a project calls for a hybrid approach.

Hybrid is an approach to investigate, not a preset system. The responsible structural engineer establishes the design and final material strategy.

Start from the ground. Follow the concrete structure, its connection to steel and the coordination that brings them together.

01 / Foundations & conditions

Start with
the ground.

Geotechnical information, levels and foundation requirements establish the starting point. Understand the ground and the intended structure before choosing the approach.

Site information / Levels / Foundations

02 / Reinforced concrete

Let concrete
do its work.

Foundations, columns, cores and slabs need buildable details. Resolve reinforcement, formwork, joints and embedded items before placement begins.

Reinforcement / Formwork / Pour sequence

03 / The hybrid interface

Resolve the
meeting point.

Where concrete meets steel, define the load path, bearings, connections and tolerances. Each material has a role; the interface has to make that role clear.

Bearings / Connections / Tolerances

04 / Construction coordination

Build one
coordinated whole.

Bring drawings, temporary works, placement access, curing and inspection requirements into the construction sequence. Keep the design intent connected to the work on site.

Sequence / Inspection / Quality records

The model illustrates material relationships. It is not a standard structural system. Stability, member design, connections and temporary support require project-specific engineering.

Concrete knowledge. Connected decisions.

Where the materials meet

The steel wing.
Its floor, in detail.

A hybrid approach gives concrete and steel defined roles. The floor, its supports and the connections between them need to be developed as a coordinated assembly.

Concrete and reinforcement

The cutaway reveals reinforcement within the concrete topping. Concrete fills the deck profile beneath the finished surface. Slab depth, reinforcement and cover are determined for the project.

Choose deliberately

The right combination.
For the right reasons.

Some buildings suit an RCC frame. Others call for a hybrid approach. Compare the options around the design brief and the site.

01

Reinforced-concrete structures

Concrete expertise across foundations, reinforced-concrete superstructures and floor slabs, with design intent carried into the construction sequence.

  • Foundations & superstructure
  • Reinforcement & formwork
  • Placement, curing & inspection
02

Concrete core + steel frame

Give the concrete core and steel frame clear structural roles. Coordinate the stability strategy, bearings, framing and construction tolerances with the responsible design team.

  • Defined load paths
  • Concrete-to-steel interfaces
  • Sequence & temporary stability
03

Steel frame + composite floor

Bring the concrete floor and its steel support into the same design conversation. The performance of the assembly depends on its detailed design and construction.

  • Deck & concrete specification
  • Reinforcement & connections
  • Openings & edge conditions
04

Extensions & existing interfaces

Understand the existing structure before planning the new connection. Reliable information and clearly assigned responsibilities shape the next step.

  • Existing structure information
  • Condition & capacity assessment
  • Connection & sequence design

These are areas for project discussion, not completed project references. Suitability and delivery scope are established for each brief.

Concrete quality begins before the pour

Plan the sequence.
Protect the intent.

Good site work depends on decisions made early and followed through. We bring the construction scope into coordinated structural discussions.

  1. Establish the design basis

    Site information, intended use, structural requirements and responsibilities.

  2. Resolve the details

    Reinforcement, formwork, joints, openings and embedded steel.

  3. Coordinate the sequence

    Temporary works, placement access, pour planning and curing.

  4. Follow through on quality

    Inspection requirements, acceptance criteria, records and handover information.

Plan composite construction around the interfaces.

A composite construction enquiry in Pakistan should identify where steel and concrete are intended to act together and how the wider building will be delivered. The floor study explains an interface; the building model illustrates a mixed structural arrangement.

Set the responsibilities before procurement

Coordinate beams, deck, shear connections where required, reinforcement, concrete and openings with the responsible designers. Confirm the construction sequence, temporary works, service routes and inspection requirements as part of the project scope.

Read the composite floor coordination guide for the questions to resolve before comparing packages. Bring the intended use, drawings, available load information and programme to a composite construction enquiry.
