Layout

Establishing the plan’s boundaries utilizing surveying technologies to set elevations for accurate concrete foundations and formwork.

Shallow and Deep Excavations

Engineering the design of how a structure transfers loads to the Earth; Depending on influencing environmental factors they can be one to two feet from final finish elevation (standard slab on grade footings) or they need to have a more adequate load capacity going to deeper soil or bedrock (piers, drilled piles/caissons, helical piers, columns).

Foundations

Concrete system of slabs and footings used to support a building or structure that evenly distributes the load or weight over rock or soil and firmly stabilizes and prevents differential settlement.

Pile Caps

A structurally thick concrete mat that rests on concrete or timber piles to evenly spread or displace the load the pile carries, and is usually part of the foundation of a building such as a multi-story unit.

Rebar Installation

The process of taking fabricated reinforcement steel rods (sometimes field cutting for desired length and or bend angle) and laying them out in a grid pattern with proper overlap, tying securely (setting the cages if necessary for reinforced footings), and using brick or bolster supports to suspend for proper concrete coverage.

Cast-In-Place Walls

Whether above or below-grade, these reinforced walls are made by pumping concrete into removable forms erected on site.

Slabs on Grade

Part of the foundation of a structure formed from directly placing concrete onto compacted subgrade and or subbase to ensure a structurally sound building. Seen referred to as SOG in many plans and can have PSI of 3,000, 4,000, or 5,000.

Place & Finish

The process of physically pumping concrete on site and then using the necessary tools and techniques to ensure a high-quality slab – Vibration is used for consolidation to eliminate pockets, honeycombs and entrapped air; Screeding is the process of cutting off excess concrete to bring the top surface of the slab to proper grade; Bull floating levels ridges, fills voids, and smooths the surface; Panning by either a machine or hand trowel places the proper aggregates just beneath the surface while smoothing out imperfections and allowing the concrete to breath; Burning and curing are the last steps in finishing properly placed concrete.

Saw-cutting

Designed, predetermined, and perfectly timed cuts in the concrete as a way to generate joints that control cracking due to the inevitability of concrete shrinkage.

Slabs on Metal Deck

Concrete placed on a form of metal decking (or composite decking) to act as the floor for that level of the building. It is usually then covered by another type of flooring (tile or carpet), and is placed via pump with careful consideration to avoid deflecting.

Concrete Filled Pan Stairs

A common and economical stair design using metal framing made of sheet steel with thin sections of concrete placed in the stair treads and landings for walking surfaces.

Topping Slabs

Typically, a thin slab used to level a floor elevation, provide a new/smoother surface over an existing slab, or used in purely decorative purposes for staining or stamping concrete.

Joint Sealants

Polyurethane product that is placed in all joints of the concrete slab to prevent water damage, keeping both water and air out (exterior and interior). It also helps reduce sound transmission through cracks.
