Building a Total Precast Structure?

Interior Design Flexibility
Long-span precast concrete systems help building owners adapt to changing client needs in future years. Hollow core slabs and double tees can span 14 to 16 m (45 to 50 ft) to match typical composite-steel framing and minimize the need for interior columns required with cast-in-place systems. Precast can span as far as 21 m (70 ft) to provide flexibility for challenging interior requirements. Precast also provides high loading capacity at little added cost.


Efficient Design
Strescon Limited can provide early and precise design assistance to help select the most efficient sizes and shapes for components, for structural efficiency and optimization for casting, transporting and erecting precast components. Member repetition reduces form costs and aids design speed while retaining design flexibility. These cost efficiencies can free up more of the budget for other critical design areas.

Strong Finish-Approval Process
Strescon Limited can provide finish samples, range samples and large-scale mockups, ensuring that design concepts translate into reality. Designers can inspect window interfaces, joint connections and other critical elements to ensure they are visually acceptable and will properly interface between trades. Plant visits to discuss technical and aesthetic concerns provide control without requiring constant site supervision.

Green Design
Precast concrete offers a number of benefits that make it environmentally friendly a growing need as the Leadership in Energy & Environmental Design (LEED Canada) criteria become more popular. Precast’s energy efficiency, recyclability, reusability along with minimal waste in the precast plant and on the jobsite are keys to meeting environmental standards that are gaining client interest.

Precast offers high thermal mass that has become a feasible element of building design. With precast's ability to aid in meeting LEED standards, the benefits of thermal mass will become more apparent to designers in the future. The use of fly ash, slag and other waste materials aid its environmental friendliness. Precast’s high durability produces buildings with a total service life that far outpaces other designs.

Construction Speed
Time is money for the entire construction team. Precast concrete's speed through design, fabrication and erection help meet tight deadlines. This particularly aids contractors when permitting processes slow down or unforeseen delays arise at the site due to soil conditions or other factors. Precast structural systems are ready to be erected when the foundations are prepared.

All-Weather Construction
Contractors can minimize the added "cushion" created in schedules to accommodate bad weather conditions, since precast components can be produced and erected all year round.

Efficient Erection
Because precast concrete pieces are fabricated in our precast plant under controlled conditions using high-quality materials, designs more exactly meet specifications. Field adjustments are reduced, creating a smooth erection process with minimal surprises.

AII-In-One Components
Total precast concrete systems allow the architectural panels to serve structural functions, limiting the need to incorporate multiple materials and trades. Combining architecture and structure provides efficiencies in a building’s lateral support systems. Spandrel panels can support floor systems and windows while providing architectural exterior finishes. Precast elevators and stair cores can support floor systems while providing secure and fire rated enclosures.

Comprehensive Drawing
A total precast concrete system ensures one-stop shopping for the entire core/shell design. Strescon Limited can design and supply the entire system, generating a better coordinated set of drawings to allow construction to proceed more efficiently. This eliminates the added effort needed to coordinate various trades when using mixed systems controlled by different suppliers.

Easy Handling
Site construction moves smoothly because no special equipment or techniques are required to transport or lift a combination of structural and architectural components. These types of activities can often require additional structural review and exposure to risk.

Shape and Design
Precast/prestressed components are custom manufactured to match design requirements. Unusual shapes, sizes and specific technical requirements are expertly fabricated in our precast plant. Repetition of shapes and sizes will greatly enhance the economical use of precast components.

Precast Efficiency
The continuous, uninterrupted erection of precast structural components lends itself perfectly to fast track construction schedules. Savings on financing costs, (faster return on investments resulting from bringing the structure into productive life sooner) is just one of the benefits provided by a complete precast building system.


Precast Structural Components
Precast concrete beams, columns and stairs are the ideal solution for owners and builders who want to achieve wide-open spans, fire resistance, energy savings and attractive design with one structural system.

These components are suitable for both low and high-rise structures. Highly durable, these concrete units can be installed in all weather conditions.

Precast beams may be either continuous with single story columns or single span beams with multi-story columns. The use of standardized forms accelerates the manufacturing process.

The quality of smooth formed finishes produced in a precast plant saves money by allowing designers to expose the structure in a finished building.

SINGLE-SOURCE PROVIDER:
As a single unit, even with stone or brick inset, precast panels require only one source to create the entire exterior wall system. When a precast structural system of columns, beams and double tees also is specified, it concentrates the complete shell construction with one certified and reliable producer. This approach ensures all of the responsibility and accuracy for meeting design specifications rests with one supplier. Consistency, tolerances, deadlines, budget and other requirements are assured.

Precast's advantages are maximized when Strescon Limited is brought onto the design team early in the planning stage. This allows our company's full expertise in designing efficient shapes, textures and finishes to be exploited, as well as our state-of-the-art knowledge on connection and erection methods.

PRECAST COMPONENTS MEET ALL NEEDS
A wide range of precast concrete architectural and structural components can be used in commercial buildings. The key pieces used most often in these designs include:

-ARCHITECTURAL PANELS:
Architectural precast wall panels are the solution of choice for the cladding on many office buildings, institutional facilities and mixed-use retail projects of all types. A key reason is that these panels offer beauty and affordable economy without sacrificing design freedom. That economy results from the low initial cost, the ability to enclose the structure quickly, the ability to continue construction through winter weather and the panel's long-term durability. In some cases, further economies can be achieved by designing load-bearing precast walls or using insulated wall panels to improve energy efficiency. These budget, scheduling and design benefits combine with precast's moldability to create dramatic and cost-effective looks for all types of commercial buildings.

-BEAMS AND COLUMNS:
A complete precast concrete structural system offers tremendous advantages and value for commercial buildings. The use of precast columns and beams makes an ideal framework for hanging precast panels, creating a design that offers fast construction, structural stability and enhanced fire resistance. A wide range of options is available for creating the perfect system to achieve the size and shape of commercial building required.

-DOUBLE TEES:
These components provide excellent roof and flooring units, spanning considerable distances and providing quick erection to close in a structure faster. In some cases, they also can be used as wall panels on low-rise commercial buildings, creating distinctive designs that require little maintenance and offer fire resistance and durability as with architectural wall panels.

-HOLLOW CORE PLANKS:
Precast hollow core flooring units provide long spans with cross-sections that reduce the height of the building, saving material cost, and their inorganic composition enhances fire protection. Strescon Limited can help determine which sizes, shapes and styles of components will best suit any individual commercial building project. Bringing Strescon Limited into the planning early in the design process will ensure the precast components maximize their effectiveness in aesthetic appeal, functionality and cost effectiveness.
