Aluma Strongback using LVL Walers
Large gang wall forms can be preassembled and hoisted into place with speed and efficiency. These panels are sometimes built over twenty feet tall and over forty feet long. One such system utilizes aluminum vertical strongbacks and engineered wood horizontal LVL walers with steel taper ties to hold the two wall forms together. Example: Job # 493 - CHOMP Pavillions, Monterey, CA
Architectural Arch
Architectural Arches can be used so that significant spans can be achieved. The arch is a very useful structure as it is completely self-supporting, typically used in entry ways to give a feeling of height and openness.
Example: Job # 372 - Rocklin Second Middle School, Rocklin, CA
Architectural Columns
Architectural column forms are often designed and constructed to add strength and/or architectural elements to a particular project.
Example: Job # 392 - Fairfield Transportation Center Parking & Bus Terminal, Fairfield, CA
Architectural Pattern Wall
Architectural walls often have feature patterns. These patterns can be imprinted with the use of custom form liners attached to the wall form face. The look and style of the patterns are limitless. Example: Job # 493 - CHOMP Pavillions, Monterey, CA
Architectural Walls
 Architectural walls are commonly designed to combine the buildings structural and architectural elements. By combining these elements a dramatic façade can be create while generating a building exterior that requires very little maintenance.
Example: Job # 461 - School of Music & Arts, Mountain View, CA
Below Grade Basement / Parking
Below grade basements are commonly used to facilitate parking for the tenants in the above grade structure. These below grade areas often combine the parking with mechanical and equipment rooms, which do not need to be readily accessible to the public.
Example: Job #473 - 333 First Street, San Francisco, CA
Cast-in-Place Basement Walls – Special Perimeter Jump Form
Cast-in-Place basement perimeter walls are commonly used as perimeter retaining walls and are often combined with the shear wall elements of the structure. Combining these elements can considerably reduce the amount of wall required in a given structure.
Example: Job #471 - Olympic Health Club Expansion, San Francisco, CA
Columns – Typical Handset
Typical handset column forms are made up of plywood back with vertical 2x4’s on edge. These panels are set individually and then wrapped with scissor clamp to produce a complete form. The spacing of the vertical 2x4’s and scissor clamps may vary depending on the concrete pour rate and mix design. Example: Job #460 - Museum Place South, Portland, OR
Core Wall – Crane Hoisted Jump Form
Multi story buildings are frequently designed with an interior shear core wall. The walls typically surround either the elevators, stair wells or both. The shape of the core walls can vary form square to rectangle to “U” shaped. The use of core walls is structural efficient and provide a space to isolate the noise generated by the elevators and stairs. Example: Job #473 - 333 First Street, San Francisco, CA
Core Wall – Self-Climbing Jump Form
Self-climbing jump forms are very similar to crane hoisted jump forms except these forms tend to be designed slightly heavier and made of predominately steel parts due to the extensive reuse the form will undergo. The use of a self-climbing mechanism attached to the form allows the entire form to be hoisted at one time creating efficiency. Example: Job #383 - Gap World Headquarters Building, San Francisco, CA
Dome Slab
Suspended slabs designed using fiberglass or steel dome forms are commonly used in building that require the structure to resist movement and vibration which can not typically be achieve using a normal flat slab configuration. A soffit form is typically installed and the dome forms are placed on top to create the desired configuration. Example: Job #464 - UCLA Physics & Astronomy Building, Los Angeles, CA
Columns – Heavy Gang, Swing-Open Form
Heavy gang swing-open column forms are designed heavier to withstand the extensive reuse and higher pour rates. The hinged swing open design allow the form to be set and stripped using one pick, creating labor and crane efficiency.
Example: Job #473 – 333 First Street, San Francisco, CA
Flat Slab – Handset - Shores (Frames), Stringers & Joist
Handset shoring has been in use since begin of our industry and is still use efficiently today. Handset shoring is typically used in conditions that do not lend the material to multiple reuses or in situations that are very cut-up with varying shaped, sizes and elevations.
Example: Job#142 - UCSB, Engineering Unit II, Santa Barbara, CA
Flat Slab – Handset - Titan, “HV” Shoring
Titan “HV” shoring has only been commonly used in the US for the last five to ten year, but has been in use over seas for several decades. “HV” shoring is a light weight modular system which can be used to shore flat slab efficiently that don’t lend themselves to flying forms or ganged deck panels. Example: Job #456 - Seattle Waterfront Marriot, Seattle, WA
Flat Slab – Handset (High Shore) - Frames, Stringers & Joist (or Deck Tables)
Suspended flat slabs which are designed with a floor to floor height that is greater than 12 feet require special consideration, planning and engineering. These types of slab are most commonly shored using multiple levels of shoring stacked on top of one another to achieve the desired shore height. Example: Job #493 - Community Hospital of Monterey Peninsula - Pavilions, Monterey, CA
Flat Slab – Typical Flying Forms
Flat slabs are typically used on High-Rise and Mid-Rise hotels and Residential structures which produce the most usable space for the end user and maximize the building space. When the slabs have sufficient repetition flying forms can be utilized to increase labor efficiency and improve schedule time. Example: Job #473 - 333 First Street, San Francisco, CA
Flat Slab with Column Capitals (Formed with Gang Tables)
Flat slabs with column capitals are most commonly used in parking areas situated below office, hotel or residential building. This configuration is used in lieu of long span beams to accommodate the structural layout of the subsequent buildings above.
Example: Job #378 - Franklin Templeton Building 5, St. Petersburg, FL
Foundations – Mat Slab Edge Forms
Mat slab are used to provide the foundation system for a building and double as the slab on grade for all types of structures. Large mat slabs which are above or slightly below grade commonly require an edge form of significant height. Since these forms are one-sided in nature it is necessary to provided adequate external bracing to withstand concrete pressures. Example: Job #333 - Wafertech, Camas, WA
Framing – Exposed Structural GLB Trusses
Architectural features are commonly used to provide shape and definitions to one-story wood framed structures. These types of areas are typically higher than surrounding areas and are difficult to access, but this is necessary to create the dramatic features illustrated in the figure to the right. Example: Kaseberg, Crestmont and Cirby Elementary Schools, CA.
Long-Span Beam Parking Structures – Typical Steel Beam Form
Long-Span Beam parking structures consist of vertical columns and/or walls which support approximately 60’ long beams spaced on center for 17 feet to 25 feet. In this photo heavy-ganged steel beam forms are being utilized to form the typical 60’ sections of beam.

Long-Span Hybrid – Precast Columns and Beams with Typical Deck Table Long-Span Beam parking structures consist of vertical columns and/or walls which support approximately 60’ long beams spaced on center for 17 feet to 25 feet. In this photo precast columns and beams have been used to provide the vertical and horizontal load bearing elements and a cast-in-place slab and moment frame have been utilized to provide the remainder of the structure. Example: Job #494 – Solano County Government Center Parking, Fairfield, CA
Moment Frame – Perimeter Condition
Moment frames are utilized to provide shear elements of a building in lieu of shear walls. This is commonly used on parking structures and buildings to minimize the interruption of interior building space with shear walls. Moment frames typically contain extensive amounts reinforcing steel and need to be adequate in width to accommodate such. Example: Job #539 – Britannia East Grand Parking Structure
Moment Frame – Interior Bent Condition
Moment frames are utilized to provide shear elements of a building in lieu of shear walls. Interior moment frames were used a in this structure to lower the overall weight of the structure and help reduce some of the structural design requirements.
Example: Job #376 – 233 Brannan Street - Phase I, II & III, San Francisco, CA
Pan Slab (one-way joist slab) – Typical Steel Pan Forms
One-way joist slabs or commonly referred to as pan slabs are typically used in areas were there are either high load requirements or there is a need to reduce vibration within the structure. The slabs are referred to as joist slab due to the appearance from underneath after the forms are stripped. Example: Job #480 –Santa Clara Medical Center, Santa Clara, CA
Pan Slab – Typical Wood Forms
Typically used in areas were there are either high load requirements or there is a need to reduce vibration within the structure. In the adjacent picture the joist changed direction so frequently that it was determined using wood to form the differing configurations would be more cost effective than steel lap pans. Example: Job #489 – Stanley Hall Engineering Building, Berkeley, CA
Perimeter Shear Walls – Exterior Aluminum Strongback Gang Forms
Perimeter shear walls are used as the exterior façade of a building as well as the shear elements of the structure to provide less interruption of the floor space with interior shear walls. Aluminum strongbacks were used in conjunction with LVL walers to produce a rigid gang form that would produce the client’s desired finish. Example: Job #447 – Children's Hospital Building, Los Angeles, CA
Podium Slab
Most commonly at ground level and typically form the foundation for one or more buildings which continue for the ground floor. Podiums slabs tend to be thick and vary in elevation to accommodate the landscaping, stairs and even fountains. Most podium slabs are form using some variation of handset material to accommodate the varying conditions. Example: Job #432 – Downtown Sunnyvale, Sunnyvale, CA
Shear Walls – Crane Hoisted Jump Form, Free Standing provide the lateral support for structural steel building or precast structures. Using cast-in-place shearwalls help to minimize the design of the precast and steel connections. In the adjacent picture heavy ganged aluminum strongbacks and LVL walers were fabricated to make form that could be jumped multiple times and accommodate a working platform safe access. Example: Job #487 – IRS Compliance Parking, Fresno, CA
Shear Walls – Interior Gang Forms
Interior shear walls are commonly used to provide the necessary lateral support for multi-story cast-in-place buildings. In the adjacent picture Aluminum strongbacks and aluminum walers were combined to form heavy ganged panels which could be utilized throughout the job. Example: Job #451 Evergreen State College, Olympia, WA
Shotcrete
Shotcrete is a process where concrete is projected or "shot" under pressure using a feeder gun onto a surface to form structural shapes including walls, floors, and roofs. The surface can be any surface that concrete can be projected onto. The surface can be smoothed while the concrete is still wet. Example: Job #
Shotcrete Wall – Backing Forms
Shotcrete walls have become design option or constructability alternate on numerous projects. Given the right conditions; correct rebar space, access and structural engineer approval shotcrete walls can provide the right option for certain situations. Some of the forms used in the adjacent picture were as high as 24 feet and when complete provided the perimeter retaining wall for a wine storage building that was almost complete buried with earth. The height of the forms required aluminum strongbacks to be added towards the end of each panel to help maintain the sufficient rigidity for the shotcrete application. #394 – Cardinale Winery Barrel Storage Facility, St. Helena, CA
Slab & Beam
Slab and beam is a typical definition for a structural slab that contains beams in either one, two or multiple directions. If the beams are not designed on a typical pattern it is most likely that the slab will be formed utilizing some sort of handset material.
Example: Job #439 EPICC Swim Stadium
Slab & Beam – High Shore Slab and beam is a typical definition for a structural slab that contains beams in either one, two or multiple directions. High shore refers to shore heights which exceed 16 feet. If the beams are not designed on a typical pattern it is most likely that the slab will be formed utilizing some sort of handset material. In the adjacent photo multiple levels of steel Shore-X frames were use to form the high elevated slab and beam areas. Example: Job #489 – Stanley Hall Engineering Building, Berkeley, CA
Specialty Forming
Specialty forming encompasses a variety of differing conditions. The adjacent photo of the twisting tower at the New de Young Museum illustrates a non-typical structural design. The museum project required the use of; handset high shore, gang core forms, small flying forms, stud and waler forms, and heavy gang aluminum wall forms. Example: Job #492 New de Young Museum, San Francisco, CA
Stairs – Architectural Stairs – Handset Forming
Cast-in-place stairs accompany many of the projects preformed by McClone Construction and come in all sizes and shapes. The adjacent picture illustrates a single lift of stair with an intermediate landing. Almost all stairs configurations are specific to a single project and require the use of handset material to due the formwork. Example: Job #474 Kahala Nui, Kahala, Oahu, HI
Waler System
A Waler System utilizes a horizontal structural member to maintain the stability of wall panels and to keep the studs from outward movement, it is also the location used for the formwork tie.
Example: Job # 461- School of Music & Arts, Mountain View, CA
Wide-Shallow Beam
Wide shallow beams are typically used in locations that require additional strength for specific loads, but also require maintaining maximum floor heights below, without having a deep narrow beam becoming an obstacle.
