Casad Services: Complete Structural Design — Substructure & Superstructure

Project Overview

CASAD Infra Solutions served as the structural engineering partner for a commercial warehouse and showroom facility in Texas, delivering complete structural design services covering both substructure and superstructure. The scope included foundation design, framing plans, and construction documentation tailored to U.S. code requirements and local soil conditions.

CASAD ensured seamless collaboration with MEP and architectural teams through well-noted coordination drawings. Foundation and framing plans explicitly reference plumbing, slope locations, architectural drops, and concrete finishes—demonstrating CASAD’s commitment to cross-disciplinary alignment in BIM and CAD workflows.

Structure & Design Overview

Type: Single-story steel-framed warehouse with adjoining showroom
Material Systems:
- Primary Frame: Hot-rolled wide flange steel sections
- Roof Framing: Joist girders with metal deck roofing
- Substructure: Isolated spread footings and reinforced concrete slab-on-grade
- Slab Reinforcement: #5 @ 12” O.C. with 10 MIL polyethylene and sand cushion

Foundation Design (Substructure)

The substructure is composed of reinforced concrete isolated spread footings at grid intersections to support steel columns, with clear coordination for anchor bolt placement. A slab-on-grade floor system is designed with detailed notes for polyethylene vapor barriers and sub-base preparation to ensure performance under warehouse loading conditions.

Key Features:
- 12" thick slab with #5 rebars at 12" O.C. spacing
- Clear grid layout with anchor bolt locations referenced to base plate details
- Coordination with plumbing and architectural disciplines ensured via plan notes

Superstructure Design

Warehouse Roof Framing Plan:

Utilizes W16x26 and W10x26 beams in a regular grid, supporting open web steel joists
Joist girders are uniformly spaced and cross-braced for lateral stability
Structural steel members are detailed with shear and moment connections, designed per Texas state engineering codes

Showroom Framing Design:

Integrated with the warehouse but designed for increased architectural complexity
Multiple column types and layout adjustments to accommodate glazing and entrances
Sloped access with stair design considered in the foundation system
