hollow- core precast concrete helps manage heating and cooling demands, resulting in reduced energy costs. The safety, security, and high fire resistance it offers keep insurance rates low as well. Structurally, a hollow-core building system provides high load capacity for floors, open clear spans, high vibration resistance, finished ceilings and floors, reduced floor-to-floor height, and natural space for electrical conduit, plumbing, and HVAC ductwork.

hollowcore plank weighs less per square foot than similar decking units on the market. As a result, hollowcore plank hollowcore plank concrete floor slabs are resistant to air-borne noise and transmission of impact noise and provide qualities superior to those of a solid concrete slab of equivalent thickness. Acoustical tests show ratings The use of hollowcore plank structural floor and roof slabs will result in a lower total construction cost for your next project. The time and weather
30 May 2010 In terms of cost elements, a distinct advantage of precast concrete over cast-in-place (CIP) is speed of delivery and ease of installation, or service. for the inside dimensions of a 4-by-8-by-4-foot structure of either precast (6 inches thick) or CIP (8 inches thick), assume these facts: The price of precast concrete may have been 75 percent higher than CIP, but its Total cost of Ownership was actually about 45 percent lower, making it the clear low-cost choice.
It is assumed the plank will span the 24-foot direction. Whenever Spancrete hollowcore® plank is exposed to the elements or wet environments, it is recommended that a waterproof membrane be installed over the plank system. This will keep the topping from bonding to the plank, as the topping is considered non-structural. A standard design load for a residential garage is 80 pounds per square foot (psf). A 2-inch concrete topping will add approximately 25 psf (or 12.5 pounds per
ficient structural strength, but in small structures they were generally too ex- pensive and logistically challenging. In a large commercial project using expe- rienced crews and heavy equipment, floor systems like precast hollowcore plank and composite steel deck can be installed for as little as $5 per square foot. In smaller applications, however, installation of bulky concrete decks is less efficient, and costs typically exceed $10 per square foot. In contrast, wood-frame floors in small
Because of hollowcore's high load-bearing capacity, it can handle unique design loads from tile and stone floors, fireplaces, wall partitions, columns and even oversize vehicles. It also creates wide building trades. It can be installed on steel frames, Insulating concrete forms (ICFs) and masonry or concrete walls without special requirements. Because it can be installed in all weather conditions - including winter - hollowcore can help speed up construction schedules and cut costs.
Lower Heating and Air Conditioning costs – costs are lower per square foot because the thinner floor section reduces overall cubic feet being heated/cooled. Fire Resistance – Construction using hollow core plank can be considered non- combustible, in accordance with National Board of Fire Underwriters definition of combustibility. hollow core floor and roof assemblies construed using precast prestress slabs with a two-inch thick concrete topping will afford up to a 4-hour fire rating.

These panels readily span up to 30 feet, leaving a basement free of posts or walls. This gives the ow n e r maximum flexibility in interior space planning, and. s a ves the builder the cost of steel columns and beam d own the center of the basement.

Advantages of hollowcore. • Provides clear spans in excess of 40 feet while maintaining a very thin cross section. Available in depths of 8, 10, and. 12 inches. • Compatible with steel, masonry, cast-in-place, and other precast structures hollowcore is an extruded, prestressed concrete slab with continuous voids to reduce weight and cost. It is primarily used as a floor and roof deck system. hollowcore is very economical and provides great design flexibility. It is used in many different.
Spancrete hollowcore is still as effective and efficient as a building solution today as it was when our first plank was cast over 60 years ago. No other building system accommodates creativity and practicality like Spancrete hollowcore floor and roof building systems. Custom made components are manufactured and delivered to the job site ready to erect. Our seasoned crews are capable of installing as much as 10,000 square feet of plank per day. Spancrete hollowcore can be

Using an extruded process, hollow core plank (or hollow core slab) is a plant-manufactured prestressed concrete slab with continuous cores, or voids, which considerably reduces weight (up to 50% compared with a poured-in-place flat slab) and cost. precast hollow core plank concrete Traditionally used for floor, roof and mezzanine systems, Mid South Prestress produces up to 8,000 square feet of hollow core plank a day from all natural resources, typically in 4' sections with
a single-family home. In each case, precast concrete components offer key benefits to produce an attrac- tive, cost-effective design. Precast concrete's inherent noncombustible composition makes it an ideal material when fire safety .. plank for floor and ceiling units, as well as using precast stairs and landings. Compared with cast-in-place concrete floors, the hollowcore provided savings of $8 to $9 per square foot, he says. The hollowcore plank saved labor costs as well, notes.
