Precast concrete panels (or slabs) will typically range from $450 to $750 per cubic yard. This is a wider range of cost because there are a wider range of options and factors affecting the total cost.
What is the disadvantage of precast concrete?
Modification. It is extremely difficult to modify a piece of precast concrete if it does not fit its placement. In many cases, if the precast concrete component is not a perfect fit, the proper materials must be ordered and brought in. Without careful planning, this can cost more money and take much more time.

5 spandrel panels; and outsourced items such as miscellaneous metals, hot‐dipped galvanizing and reinforcing steel. Whether the take off is done manually or using an on‐screen program, it is critical to organize the
How much does precast concrete cost?
Now, let’s take a step up in complexity. Precast concrete panels (or slabs) will typically range from $450 to $750 per cubic yard. This is a wider range of cost because there are a wider range of options and factors affecting the total cost. If you consider the differences between a 6” thick panel versus a 12” thick panel, you have much of the same labor costs associated with setting up a casting bed for both thicknesses. You may have more steel reinforcing and obviously, you will have two times the amount of concrete material, but the total labor costs are spread out over twice as much cubic yardage equating to a lower cost per cubic yard for the thicker panel. Other factors affecting the cost could be the amount of miscellaneous steel embed plates or connection components cast into the panel. Are these components plain steel, galvanized steel, or stainless steel? Are the components stock items readily available or are they custom-built for the project? Concrete panels also have various finishes and edge treatments depending on the final use of the product. If the panel requires beveled edges, specific textured finishes, or integral color, obviously these material and labor costs start adding up. As you move into true architectural finishes, the cost per cubic yard can dramatically increase above $750 per cubic yard depending on how specialized the finished product is expected to be.
How much does a concrete sump cost?
The cost of concrete sumps will typically range between $750 to $1,200 per cubic yard. Precast concrete sumps come in a range of sizes as small as 2 ft x 2 ft up to mega-size sumps with length and width dimensions of 30 feet and greater. Generally, these larger sumps can be difficult to precast because of challenges in shipping. When the smaller dimension of width or length is greater than 16 feet, the costs of shipping start increasing exponentially due to the required permits and escorts needed. If the volume of the sump is more critical than the shape, precast can normally be incorporated in the design by creating a rectangular design and limiting the inside width of the sump to 10 ft. The required volume of the sump can be attained by increasing the length and depth and you get the benefit of reduced shipping costs (shipping costs are discussed below in this article). Sumps will normally have multiple manway access openings along with vent pipes and inspection ports. Depending on the type of material (aluminum, steel, cast iron) and the size of the access, the cost will range between $300 to $1,500 for each access. The cost of vent pipes will range between $40 to $100 each depending on the size and material. Another potential cost associated with sumps can be the lining of the internal walls. In many cases, the water contained in sumps can have abrasive chemicals requiring a sprayed-on liner coating or a liner material integrally cast into the concrete wall. These liner systems can vary widely depending on the application needed, but internal liners can cost between $20 to $60 per square foot of surface area.
How much does a dry utility manhole cost?
The typical cost for utility vaults, electrical manholes, communication manholes, and handholes ranges from $700 to $1,100 per cubic yard. Although these structures can be very similar to standard precast drainage structures, they typically require more embedded items to accommodate the connection with buried conduit and to help facilitate the installation of electrical or communication wires. These embed items could include anchors for pulling cable, electrical grounding devices, conduit couplers are known as terminators, cast-in threaded inserts to accept bolts for equipment installation, and floor sumps to aid in pumping water out of the structure. Another large cost associate with these utility structures is the access cover or hatch. With the need to access these structures more often, the access hatches are typically galvanized steel or aluminum and require more safety features than a typical stormwater manhole. These access hatches can vary significantly with size, material, and load rating being the primary cost differentiators. The cost for these hatches could range between $300 to $1,500 per structure with a smaller 2 ft x 2 ft hatch on the lower end and a 4 ft x 8 ft on the higher end of the cost spectrum.
What is a dumb concrete block?
A good example of what I like to call “dumb” concrete would be a concrete ecology block. This “eco-block” is a block of concrete generally 2 ft wide x 2 ft tall x 4 ft long and would typically cost $375 to $425 per cubic yard. They have a groove on the side, and they are stacked and interlocked to create wall systems generally used to separate material stockpiles. These wall systems are common at ready-mix operations separating the various rock and sand aggregate materials used in batching concrete.
How much does it cost to build a trench?
The cost of concrete utility trenches will generally range between $800 to $1,100 per cubic yard for the base portion of the trench. The main factor impacting this range of costs is the system for securing racks or supports for the piping. This can be as simple as providing threaded inserts cast into the walls to accept bolts. Other methods could include providing a cast in support system such as Unistrut or providing cast in weld plates to allow for a welded connection of pipe supports. The materials can range from standard black steel to stainless steel, to non-metallic materials such as fiberglass. The length between the necessary pipe supports is generally dictated by the type of piping material used and how much support is necessary. We see support systems ranging anywhere from 5 ft to 20 ft between supports.
Why is concrete called dumb?
We call this “dumb” concrete because it is such a simple concrete structure typically with only a single lifting anchor cast into it. Usually, there is no steel reinforcing, no additional embedded steel components, and no CAD or engineering design work required.

What Is a Concrete Slab?
A concrete slab is a flat, horizontal surface made of a wet cement mix and crushed stones that hardens or cures into concrete. This curing process is a chemical reaction that ensures strength and durability against weather, weight, and use. A slab can be built directly into the ground by several inches as a foundation, or it can be suspended above the ground to form a flat floor for a multistory building.
How to ensure concrete slab lasts longer?
To ensure the concrete slab lasts longer, a concrete specialist will determine what kind of mix is best for your project. It could impact the price slightly if your mix needs a higher amount of cement or aggregate than average. Also, if you need to add a concrete wall on the edge of the slab, you’ll pay more to have the shape formed and poured.
