L ES IN lum fo O V E A R EASI rsaA THAT


FORSA is a company founded in 1995 in Cali, Colombia. Based on its personnel’s excellence, its product innovation and its processes’ technology. Currently, we are leaders in the Latin America and Caribbean Design and manufacture of concrete forms for the mass construction of concrete housing. We are operating over 18 countries in Latin America, Europe and Africa. FORSA has designed a construction system aimed at the mass production of concrete housing. The system it’s sustained in the daily use of an aluminum


cast that makes at one time 100% of a housing unit’s structure (Unfinished work). This cast is composed by standard metric concrete forms which are assembled in different configurations according to each project’s architectural specifications. Forsa’s manufacturing plants in Colombia and Mexico are focused on offering practical and efficient housing solutions according to the different and changing Builders’ needs. Loyalty, motivation, learning, shared values and the harmonization of interests is essential elements at FORSA. Each member of our company is motivated to improve the performance of the products we manufacture, always thinking in how to increase our customers’ productivity. FORSA’S success is based on its deepest commitment: management based in loyalty, a management style that develops solid associations between our customers, suppliers, employees and shareholders.

Multiply your Productivity

We work with you from the project’s planning stage by assessing you in the technical specifications and in the definition of the housing’s dimensions, because we know that when you obtain FORSAalum equipment you DO NOT necessarily want to “Stick to” the same design for the entire panel’s useful life. That’s why we always design trying that at least 80% of the formwork is made with standard pieces that allow its total restructure for different projects. FORSA offers more productivity to your job, making it faster, more economic and safer. FORSAalum’s pannels are designed to be used more than 1,500 times, with the proper maintenance will generate economy at great scale.


Increase The Build Number Of Housing Units Per Month By being FORSAalum a monolithic system, the execution time of a house is reduced considerably (less than half the time) compared to the traditional system, since it allows pouring in just one stage, the façade’s walls, internal dividing walls, architectural details and the house’s slabs. FORSAalum allows ore productivity to your work project, making it faster, more economic and safer.

Reduce Labor Costs FORSAalum’s system is very simple to use and with very few accessories. The workers that will handle the concrete structures will require minimum training without having to use cranes. FORSAalum’s concrete pannels, only weight 22 kg/m² making them easy to carry and to handle, making their assembly and disassembly an easy sequence.


Use Less Material in Finishings, and Have Less Waste Materials in Work Sites In the traditional concrete block construction system the walls are plastered and a paste is applied after to finish it. With FORSAalum’s, system the walls and slabs are ready for the paste to be applied (3mm) directly on the surface and they can even be left as they are, thus saving finishing costs. FORSAalum’s system, allows clean and waste free work sites that generate the constructor considerable savings.

Fosa’s Technology is Flexible Our philosophy is to design solutions for you that allow you to integrate in your cast the special pieces so your architectural design ends up as it was conceived. From the “drawing board”, door frames, lintels in windows, interior edges up to different interior slab types that are poured jointly and do not leave margin to the costly touch ups or re-works.


Build with more Assesment FORSA, through its service, offers continuous follow up assessment to the builder always trough highly trained personnel from pre-project planning to the conclusion of the construction in order to improve your experience with the system in order to help you achieve a permanent optimization of the resources and the integral success of the job project.

Total Profits Guaranteed The cost analysis made quantitatively and in a true way show the benefits of FORSAalum’s system for the industrialized construction of concrete structures. We Count with cost analysis of all of the countries where we have casts operating. We have compared FORSAalum’s system with other construction systems such as Clay, Brick and Concrete structures (block), the traditional and pre-fabricated systems and the yield results, in materials, cost and time savings are worthy.

Walls system Corners for Internal Walls

Aluminum profile used to form the inner corners at 90 degrees with the wall panels.


3/8" thick aluminum profile that is used to close the wall. Is assembled the same way as the panels (with pins and stays), and at times, if the configuration is not standard, pin staples can be used. For walls with a thickness of over 12 cm the wall tops are reinforced with angle profiles or a tubular profile.

To facilitate the unpacking of the wall panels and slab, the internal corner is modulated in two sections; the upper one covers the wall-slab union up to the first drilling of the wall panel and the lower section covers the rest of the wall panel’s length. The corners in their upper part have caps in order to make perfect assembly with the tile and Wall-slab Union. When the Wall- Slab Union is the edge type, the corner cap has the same type of edge.


When the design requires wall recesses setbacks or lintels in the beams, it is necessary to use wall tops with a mold. These are manufactured with 6061 aluminum profiles properly reinforced, which are secured to the wall panels with pins and stays or pin staples if necessary.

Walls system Cross Corner The cross assembly is formed by four wall corners. It’s coupled with pins and stays as all the other panels.

The "L" assembly The assembly or "L" corner is made of four parts: • A wall corner. • An exterior angle. • Two panels of width equal as the thickness of the wall, plus the wall. Corner These pieces are attached with pins and stays.

The "T" assembly Is always made with three parts: • Two wall corners. • A wall panel of width equal as the thickness of the wall plus 2 EQM. These pieces are attached with pins and stays.

Panels for Back End (Culatas) Determine the shape, height and inclination angle of a wall. The Panels for back ends are conected to the wall panels with pin staples at the bottom edge and pins and stays on the side edges.


Walls system In the industrialized construction houses share the same walls between them and, some times there are double walls with expansion join between them, so the FORSAalum system uses the necessary accessories for easy pouring or casting of these walls.

Their function is to set the ties that bind the already cast wall with the wall panels with which the other wall is going to be fastened to, in order to give it the necessary adjustment that ensures the thickness of the wall. For each tie an angle stay must be installed.

Walls system Doble Wall With Expansion and Uneveness Join For land unevenness of less than or equal to 50 cm and in multiples of 5 cm between one housing unit and another within the same house. FORSAalum’s System, delivers the milled panels with drillings or slots in the three perforations in order to facilitate the passage of the ties that are going to bind and maintain the wall thicknesses.

Shared Wall In industrialized construction shared walls are common in housing units. For that reason, it is necessary to leave the housing’s overlapped in order to make a joint with the next unit. For the overlapping of the steel in a work site wood is usually used, but FORSAalum trying to optimize the system developed the Cap key for vertical walls with only one mesh.

Wall Tensors They are used in order to place a wall to plumb. The strut connects easily to the wall form with the same supporting accessories (pin and stays). Its pivoted end design allows it to adjust to the floor in order secure its position.

Double wall wedge cover It allows the generation of continuous and even construction joints, with very good presentation in places where the cycle of armed forces to interrupt the pass of the concrete in the wall and for structural reasons it’ll be required to use double mesh.


Walls system Adjustment Filler It is used as an adjustment element or for general use when the spaces are not multiples of 5 cm. In the event that different housing units are constructed with the same equipment, even with wall thickness changes.

Aligner Scaffold They are installed over the wall panels, as platforms for upper installations of back ends, sides and’ borders.

The 1 cm profile is very useful in the equipment adaptations.

Standard Slab Panel

The lateral profile is used grooved and is perforated for the assembling of a panel to another. This grooved profile permits the use of these panels in different positions fastened with pin staples since there is no coincidence between the perforations and between panels. They are handled as standard 90 x 120 panels. But according to the required design they can handle widths and lengths from 10 to 90, with different combinations. Width of the side rail: 54 mm. Contact face 1/8" thick.

Slanted Connector

This piece functions as a connector between wall panels and slanted slabs. Each panel is manufactured with the required corner angle according to the slant of the slab. Step

The slab is joined to the WSU with a staple pin.


Slab bracing system Bracing Slab The dimension on this panel varies according to the slab casting. Its function is to keep the slab braced during and after pouring, that’s why 3 sets of these slabs are provided.


Jack Support This accessory is used to keep the panel leveled during the concrete pouring. (smelting). They are installed at the intersection or jointure of three or four slab panels. They are removed when the slabs are stripped.

Fastenning accessories The Accessories for fastening the panels on wall systems are made of thermo treated highly mechanical resistant steel that permits them support high work loads. The wall panels can be supplied with arrow pins, accessories that are fixed and are installed on the panels from 45 cm to 90 cm wide.

Arrow Pin Together with the stay ensures the fastening of the panels. Their galvanized finish is a long-lasting protector shield.

Pins Accessory that together with a stay serves to fasten the wall panels together with angles, wall corners and wall tops end seals as well as for the basic fastening of slab panels. They can also be used as complementary fastening accessories where there are fillers and adjustment profiles.

Flat Pin

Threaded Pin Functions as a variable length bolt so that can be used in any filler, since the nut it has moves through the thread giving it the necessary length for each case.

Short Pin

Stays They work together with the pins and arrow pins. They are curved shape allowing easy insertion and lessening the risk of damage to the panels. Because of its challenging use, we recommend maintainance and change every 250 uses. If it’s too damaged and doesn’t fit, the panel must be changed.


Fastenning accessories Staple Pin Accessory used for the fastening grooved rails with perforated rails such as: • Slab Panels with Wall Slab Union Panels. • Wall Panels with Wall Slab Union Panels. • Wall tops with wall panels. • Slab panels with strut slab. • Slab panels among themselves.

Ties Carbon steel accessories used to fasten and separate panels defining the thickness of the wall. They are installed at the panel joints trough the height every 30 cm. Due to its demanding function, it is suggested that they be checked and changed every 250 uses. If they are excessively worm and do not adjust well, they should be replaced.

Alignment fasteners Horizontal Aligner This accessory helps to maintain the wall wok forms aligned. The first two Aligners are installed at the ends of each wall, and they continue to be installed at every form work joint. After that, you install the (2 ½” x 2 ½” x ¼”) aligner angles (FORSA does not supply these angles). For walls up to 2.40 height, a line of aligners should be installed in the highest part of the work form and another in the lowest part. For higher heights we recommend to install aligner 3 rows.

Aligner Angles 2 ½” x 2 ½” x ¼” thick


Alignment fasteners Threaded Point Aligner


Fast alignment System that is, safe and easy to install, that besides aligning the wall panels horizontally permits their alignment between butts and gable panels. Is made by a plate installed to the panel with a pin and a stay and by the threaded bar that holds the double tubular aligner with thumb-screws (quick adjustment screws). Step

Fix with the pin and the stay in the joint of the panel, and/or cap or butts.


Insert the aligner between the two tubular aligners.


Secure the aligner to the tubular using a thumb screw. Its Design allows aligners to be installed in diagonal over the timber Panels.

Telescopic strut, light and easy to install works in heights from 1.0 m to 1,65 m. They are special for propping stairs, projected scaffolds when they have rails and window openings.


Alignment fasteners Tensors for Windows and Doorways The perfect dimension for windows and doorways is guaranteed by the proper use of these tensors. Its extendible strut design allows adjusting windows and doorways distance.

* When the door ‌ has no lintel, we recommend you to install two tensors, one on top and one on the bottom.


Alignment fasteners Wall - Slab Union Support Accessory that aligns the wall panels with the wall slab union, ensuing straight angles more precise between the wall and the slab.

Wall Complement Aligner This accessory meets the following functions: • Vertically aligns the wall panel with the muro con el complemento. • Aligns horizontally the wall panel. • Delimits the height’s risk area.


Special formwork Panels for Foundation Slabs Combination of panel and support to form the thickness in the foundation slabs. They are made in different heights and lengths according to the casting and design required. Its fixation is done directly in the ground, with 5/8�diameter construction rods.

Panels for Domes The architectural designs for over placed domes in the slab are made with a combination of aluminum panels and corner angles which are stiffened with a steel angular structure. The dome panels are all designed with an inclined angle to facilitate their dismantling process. When the domes stay inserted on the slab, negative steels with dismantling angles are sent, which are fixed with screws directly to the slab panels.

They can be made in heights of 10 cm or more. They are joined together using pins and stays.


Types of scaffolds There are different kinds of scaffolds that can be installed according to the design of the housing unit with the objective of generating a circulation platform that allows the assembly of the FORSAalum system in all exterior faรงade areas, and several elevator and stairs spaces guaranteeing the proper safety and protection to the workers.

Scaffolds Scaffold Lintel

Types of scaffolds Basic Scaffolds The three types of basic scaffolds are used on straight walls and in the inside and outside corners of the project maintaining a maximum distance of 1.8 m between them.

Lintel Scaffolds

Overhang and/or Ledge Scaffolds

Besides basic scaffolds, Forsa designs the scaffolds you need for your project.


Security system for high rise constructions External Scaffold For the assembly of the panels on the second, the external scaffold should be installed in the entire housing’s perimeter, because these besides holding up the angles that support the panels of the façade’s walls, stairs and elevators vacuum space, also provide the function of generating the exterior platform for the workers’ safe movement.


Step Once all the scaffolds around the house are installed according to the modular blueprints, proceed to install the scaffolds and the life lines.

If wood is used in the scaffolds we suggestto have its support at a minimum 1.80m length and 2" thick making sure that the overlaps rest on the scaffolds not on the air.

To each one of the scaffolds should be fixed two ties of 5/8” X 2” screws. Each scaffold is installed inserting the ties in the concrete wall’s grooves of the lower floor.

Guardrails: FORSA offers builders a series of physical barriers (with resistance measures and endorsed byinternational standards), which delineate the area at risk in the biuilt heights, ensuring a safe operation of our panels.



Once the ties are inserted they are secured in the internal part of the wall with the stay in angle pin an stay.

Security system for high rise constructions Step

The grooved angles are inserted in the cavity that each scaffold has maintaining properly adjusted and aligned against the wall to have a good support surface for the façade’s formwork of the following floor.


The assembly of the exterior panels or façade over the angle begins at one end of the housing unit. When Joining the panels to the angle with a staple pin they are positioned correctly against the already cast wall guaranteeing a very good splice from one floor to the next.

Strip the external facade panels of the last pour of the lower level.

Verify that the "mean dilation" is correctly induced in the upper end of the wall and clean the surface.

Once the stripping process starts, the faรงade panels must be removed complete with their angles fixed. Then the angle is dismantled and moved to the new scaffold assembly area (Try to have this activity done in a timely manner to release the aluminum angles as soon as possible in order to be armed with the scaffolds).

Once the scaffold system suitable for this purpose (see assembly blue prints of upper levels), assembly on them the grooved aluminum angle, placing the dilation of this piece in full contact with the one induced in the concrete.

Note: The aluminum angles should have the stripping agent applied properly.

Step Step


Once the outer walls of the upper level are armed (according to the implemented sequence), fix with staple pin the panel bases to the grooved angles and make sure that this group makes one piece.

Verify proper installation of mesh and steel according to the structural requirements and proceed with the installation of thermal insulation which must have the necessary rigidity to prevent warping, ensuring its ideal position. In some cases achieving this stiffness leads to the use of smaller diameter mesh as a support for isolation, or to the use of some additional system providing stiffness to the same isolation.

Install sufficient amount of mesh separators and thermal insulation in order to ensure the ideal separation between screens, the desired location of the insulation and the expected coatings.


If possible avoid thermal bridges that may arise in places such as doorways and window’ openings, crosses and wall finishes, sites where the insulation can lose its continuity interfering with the structure’s thermal behavior. The use of galvanized profiles improves the isolation performance in these critical areas.

Finally proceed with the installation of the panel Besides this system there are other alternatives for attaining thermal insulation, such as the implementation of a second wall block or pouring concrete later, or the adhesion of a thermal coating to the inner face of the facade wall.

Slabs for masonry walls or block Forsa has designed a system for building concrete slabs on masonry walls or block, in order to facilitate and agilizarle the constructor pouring of the slab, because this type of construction requires more time to have the slabs ready. This system is based on a set of slab formwork supported on a transitional or supplement panel by struts around its perimeter. Inside the slabs using the slab prop strut. It is very important that the walls of masonry block or plumb. Masonry walls

Columns Types

FORSAalum’s system allows the construction of columns, beams and slabs or combined systems with wall panels. All panels are made of aluminum profiles. The assembly accessories are made of high strength steel heat treated. The columns are formed with panels and angles.

FORSA manufactures transition aluminum panels, which receive all parts that make up the dropped beams. Then the slab system is installed, with all its underpinning.

And this way is preceded, floor by floor.


With FORSAalum forms all types of sections in columns (straight, circular or elliptical) are achieved. These panels are designed with the necessary reinforcements

Other systems Assembling the formwork for stairs Step

Make traces or references of the ladder in the walls that surround it (if only one section without walls on the sides, clearly define and trace start and end of the first step). Ensure that the trace actually corresponds to the modulated FORSAalum drawings.


Secure the skeleton as indicated in the side walls drawings, following the traces made. Use 3/8 " concrete steel nails of 2" or 1/2 " lenght.


Attach the skeleton the bed using pins and wedges, as the parts are being mounted, it is needed to prop.


Attach the side pieces to the set, using pin and wedge.


Assemble the pieces of steps (risers in aluminum), fix them with pin and wedge.


Level the beds of the stairs, once fully assembled. Use jacks or props for that. Note: All Forsa steel and aluminum parts must be installed with its demolding agent already applied.

Tools Tie Puller It is used for the extraction of the ties that are inserted into the wall after the panels are removed. Its good performance depends on the proper installation of the material used as cover for the tie.

Panel Remover Used to facilitate stripping of wall panels.

Leveling Crawbar Used to lift and align a panel with another and to help in the "fit" between holes prior to installation of the pin.

Wall - Slab Union Remover Facilitates the stripping of the wall- slab unions so they do not suffer too much and deteriorates.


Other products Folding Ladder Folding ladder system easy to assemble and with level of adjustment at 19.15 cm, 44.15 cm or 69.15 cm, which allows you to install panels safely and reliably. Its foldable design and light weight only 26 kg makes it easy for traveling.

Ladder The access from the floor to the slab requires the use of ladders designed according to the required height, They are fastened by two hooks to the upper plate of the system.

Tie cover Polyethylene foam, which is used as a cover for the different types of ties. Its main function is to provide protection and ease the stripping of the ties, ensuring their reuse. Product presentation: • Roll of 250 lineal meters. • Corrugated boxes with covers cut to fit the width of the wall.

Wall and Slab Spacers The walls and slab separators are used to distance the welded mesh from the panel, so that the concrete remains coating evenly both sides of the mesh. The U stoppers serve to keep the panel aligned during assembly.

Steel Chip


Pad of interwoven steel wires used for daily cleaning of the panels, removing the concrete waste embedded from the previous day.

FORSA work FORSA designs and manufactures all kinds of decorative and architectural details in accordance with the blue prints specifications.

With FORSAalum system is possible to build curved, straight or in different configuration frontons. Negatives in steel, circular or straight, are fixed to the faรงade panels as details for later installation of prefabricated as gargoyles. We can make circular or straight windows, with ridges of different sizes, with or without rafters.The tops of the rafters, can be made straight orcurved, serving the needs of our customers.
