Versatility can add value to the creative architect; if we think about it, we can build almost any building and get it better.

The Immaculate Conception Parish in Cottonwood, AZ was established in 1930.

As it has continued to flourish, Immaculate Conception recently made the decision to build a bigger and better church to host its growing parish.

Ground breaking began in the latter part of 2008 and with a steadfast crew working with Quad-Lock's insulating concrete forms, the new church was dedicated on December 8th, 2009.

Why Quad-Lock was chosen

Original designs for this monumental project utilised a masonry wall system, but the decision was made to favor Quad-Lock's superior ICF system for the following reasons:

  • Height of the building
  • Improved insulation value
  • Increased construction speed
  • Reduction of project costs
  • Ease of pilaster construction (including double corner pilaster fabrication)
  • Better sound attenuation
  • Higher energy efficiencies and cost savings for the congregation

Project Profile - Immaculate Conception

The Design Vision

The design concept envisioned the use of large supporting columns and expansive ceiling spans integral to Church construction in the early 1500's.

To fulfill this vision, the building incorporated a total of 38 pilaster columns in five different designs, perfected by Quad-Lock for tall- wall applications. This provided the desired Cathedral appearance essential to the Catholic Church in this expansive project.

The floor plan illustrates the project complexity, including the corner details associated with the pilaster columns, wall height and the absence of internal supporting walls.

Integral to the design was the under- floor air ducting. Using Quad-Lock enabled forcing of air under the pews and recycling the conditioned air 14 feet off the floor, resulting in long term comfort and cost benefits for the Parish.

"This project demonstrates Quad-Lock's adaptability to complete large tall wall projects without internal floor support required in the open design of these types of facilities," Hannis Latham of Arizona Radiant Heat Barrier said.

Challenges Addressed with Quad-LockConstruction of walls on rough placed and unleveled, trenched, footings.

The many challenges of this 30,000+ sq ft project were surpassed by utilizing the flexibility of the Quad-Lock System to its best advantage.

Variable concrete consistency, truck to truck, from project beginning to end.

Scaffolding limitations when plumbing walls and erecting the extensive wall runs.

Only 277' of wall that was less than 8' tall. Wall above grade varying from 31' along the Nave, to 42' at the main entry and 49' on the two bell towers.
