  • Easier to setup and brace so multiple columns can be poured at one time.
  • Easy to cut and drill at the job site.

Important Instructions for Field Use of Sonotubes - The Duke Company

Important Instructions for Field Use of Sonotubes

How to store:  store Sonotube concrete forms in a dry place at the job site.

  • For best results, store forms vertically to maintain roundness.
  • Keep ends covered at all times.
  • If stored horizontally, elevate a minimum of 4 inches off the ground and support the full length of the forms.

Placing:  Even the largest Sonotube brand forms are easier to place either manually with block and tackle, or by crane.

  • Position over a reinforcing bar cage if desired.
  • Avoid damaging the inside surface.
  • Place individually or in groups for continuous pouring.

Bracing:  Sonotube concrete forms require minimal bracing to be brought to plumb.

  • Use light lumber or scaffolding.
  • Secure the column foot with collars if necessary.
  • If pouring bents for bridges, consider tying the column form in with the beam form.
  • Sonotube concrete forms can also be tied into other forms or structural members.

Pouring:  please note, use of a release agent is recommended with all Sonotube forms, especially when working with aggressive concrete formulations.

  • Sonotube concrete forms are engineered not to buckle, swell or lose their shape.
  • Sold in standard lengths of 12′, Sonotube concrete forms are designed to be poured in a single lift.
  • Do notexceed ACI-recommended pour rates.
  • Concrete must be vibrated during pour.

Stripping:  if stripping is required, strip the form as soon as possible after the concrete has set to prevent concrete from sticking to the form. Recommended time for the easiest and fastest stripping is 24 to 48 hours after the pour. Sonotube concrete forms should not be left on the column for more than five days.

  • Stripping options:
    • Use a circular power saw to make two vertical cuts on opposite sides of the form.
    • To prevent marring, make sure the depth of cut is less than form thickness. Remove the form.
    • Use a utility knife to cut the form from the top down at least 12 inches. Use a broad-bladed tool such as a shovel and short strokes to pry the form away from the column in a spiral motion.

What is the CSI (Construction Specifications Institute) Masterformat??

  • The CSI MasterFormat is a coding system for document organization for construction related documents including construction design specifications, contracts, construction documents and other materials.
  • The CSI uses specific numbers and titles that make up a universal indexing system.
  • MasterFormat is also a publication created and maintained by the Construction Specification Institute (CSI) and Construction Specifications Canada (CSC). Notably, the CSI is widely used in the construction and operation of buildings and systems in many industries and projects, from healthcare and public infrastructure to educational structures and commercial. residential construction.
  • Advantages of Using CSI’s MasterFormat:
    • Improved communication between project groups, by for example, the design and construction teams. CSI  allows all team members to refer to specific sections of any document using the universal coding system. This facilitates coordination and communication between project owners, architects, contractors, and suppliers, minimizing the time spent organizing documents.

For industries with complex operations, such as health care, MasterFormat helps communicate and organize critical operational information among designers, builders, operations managers, and facility owners. In addition, as these and many other industries are increasingly using building information modeling, or BIM, MasterFormat can be used by modeling software to enhance data interoperability and improve BIM adoption.
