INTRODUCING A NEW SHORING / FOUNDATION SYSTEM FOR PERIMETER WALLS ( PARKADES AND BASEMENTS).
RESEARCH CENTER FOR SFS SYSTEM
SFS STRUCTURES, LTD; ( a Calgary based enterprise, dedicated to research and development for new construction systems and technologies ) has evaluated and improved a new “state of the art” system intended to be used instead of the traditional and expensive shoring system used ( until now ) for parkades and basements.
This system is perfect for 1, 2 (or more) levels of parkade and 1,2,3 (or more) upper levels of superstructure.
One of the targets of this method is to eliminate the construction of temporary shoring systems, which as general rule, are conformed of cut-off caisson walls or timber lagging and welded piles. This temporary shoring system will be substituted for a permanent concrete wall, that will be conformed with precast concrete curved panels and piles-columns with dimension according to the soil mechanics conditions and structural features. Every pile-column will be prefabricated with concrete or steel confined with concrete, 1.0 m to 2.0 m below the grade level ( accordingly to geotechnical report ) , poured on site, with tremie tube or concrete pump.
FINAL PRODUCT , RETAINING WALL AND / OR SLOPE STABILITY
TRADITIONAL SHORING SYSTEMS
( TOO EXPENSIVE AND TOO COMPLICATED )
FINAL APPEARANCE OF THE SYSTEM
NO ADDITIONAL STUCCO OR PAINT IS NECESSARY

INSTALLING AND ALIGNING PILES
USING THE SFS SYSTEM AS A RETAINING WALL
( 5 mt. HEIGHT ) FOR A SAND FILL ON A COMPRESSIBLE SOIL
USING THE SFS SYSTEM AS A SHORING SYSTEM AND
STRUCTURAL RETAINING WALL AT ONCE
FOR AN UNDERGROUND PARKADE IN A SHOPPING MALL
TYPICAL ARRANGEMENT FOR A RETAINING WALL USING THE INTERIOR COLUMNS IN ORDER TO FRAME THE WHOLE STRUCTURE, AVOIDING ANCHORS, SLURRY WALL OR ANY OTHER EXPENSIVE SYSTEM.
5 STORIES UNDERGROUND PARKADE, USING SFS SYSTEM , SHOWING THE BEAMS FORMING FRAMES AND WILL BE USED AS PERMANENT PART OF THE FLOOR SYSTEM.
ALL THE ELEMENTS, WILL BE PERMANENT PARTS OF THE STRUCTURE AND NO TEMPORARY WORKS OR SHORING STRUCTURES ARE NEEDED.
80% OF THE NECESSARY CONCRETE PANELS AND BEAMS WILL BE MANUFACTURED IN A FACTORY, SEVERAL MONTHS PRIOR TO START THE EXCAVATION.
TRADITIONAL SYSTEM USED SO FAR.
TOO EXPENSIVE FOR ONLY TWO LEVELS OF PARKADE.
MOREOVER, IS A TEMPORARY WORK .
THE USE OF DRILLED METAL PILES ( " I " SECTIONS ) , COMBINED WITH LAGGING SYSTEM IS ONLY TO KEEP STABLE THE SOIL.
IT IS NOT A " FORMAL " RETAINING WALL , WHICH MUST BE BUILT AFTER DOING THIS EXPENSIVE PROCESS.
USING THIS SYSTEM, YOU CAN NOT DOWNLOAD WEIGHTS FROM SUPERSTRUCTURE . YOU ARE OBLIGATED TO USE A CONCRETE WALL. ( DOUBLE WORK AND DOUBLE COST ).
THE SFS SYSTEM IS A CONCRETE WALL WITH CAPACITY TO WORK AS A RETAINING WALL AND AT THE SAME TIME, IS A BEARING WALL. THE ADVANTAGES ARE OBVIOUS.
5 STORIES UNDERGROUND PARKADE CONSTRUCTED USING SFS SYSTEM.
THE ORIGINAL STRUCTURAL RETAINING WALL WAS MODIFIED, USING THE INTERNAL BEAMS AND COLUMNS, WORKING AS AN INTEGRAL FRAMING SYSTEM.
SAD EXAMPLE FOR WAISTING TIME AND MONEY ( BURIED ). IT IS NECESSARY TO USE EXPENSIVE "I" METAL BEAMS, EXPENSIVE WOOD, EXPENSIVE MACHINERY, EXPENSIVE OPERATORS AND TO PAY EXPENSIVE FEES. AFTER ALL THIS, A EXPENSIVE CONCRETE WALL MUST BE CONSTRUCTED. ( BECUSE ALL OF THIS IS A TEMPORARY RETAINING WALL).
THESE PICTURES SHOW THE TEMPORARY SHORING SYSTEM ( " I " BEAMS + EXPENSIVE LAGGING SYSTEM ) AND LATER, THE PERMANENT CONCRETE WALL MUST BE BUILT .
THE OWNER MUST PAY DOUBLE AND BURY HIS MONEY BECAUSE OF LACK OF BETTER DESIGN AND POOR CONSULTANCY.
WE CAN WATCH THAT ALL THIS VERY EXPENSIVE DESIGN WAS TO BUILD ONLY 1/2 LEVEL OF PARKADE.

Emerging trends in the industry
This slowly emerging trend in the construction industry is further picking up speed. We are beginning to see skyscrapers being built in a matter of days and weeks, as opposed to years using traditional methods.
The trend is becoming premanufactured, as somewhat uniform, structural sections are used in large-scale construction projects. Most notably, we see these premanufactured parts methods being used in places like China, where the population is experiencing exponential growth.
For the better part of history, construction has relied on the trades, bricklayers, masons, builders, and many others to bring an architectural design to fruition. Not to say that trades are dying, but rather when time is the driving factor in construction, there simply isn’t enough time to rely on human tradesmen.
Engineers, and builders for that matter, are turning to construction techniques like tilt-up building, where walls are cast in large slab sections on the ground and lifted into place. This technique allows sections hundreds of feet in length to be raised in a matter of hours.
