The minute the concrete arrives at the forms the concrete foreman and the vibrator operator become the master artists and their competence dictates the final results in architectural concrete
October 1985: Handling, Placing and Consolidating Concrete
The importance of proper planning prior to beginning this phase of the construction process cannot be overemphasized. Knowing exactly what the job requires, then having the equipment and manpower necessary to do the job, will avoid many problems.
August 1987: Conveyor Systems Solve Concrete Placing Problems
On large volume concrete pours, contractors can often combine different types of conveyors to solve concrete placing problems. Multiconveyor systems can place concrete at rates greater than 200 cubic yards per hour.
August 1991: Consider All Costs When Choosing a Concrete Placing Method
Using a placing boom can be profitable even with two tower cranes on a job.

Contractors must understand, however, that long-strip construction affects levelness.
September 1998: Placing 50,000 Square Feet of Flatwork a Day
You often can get paid a premium for fast-tracking a floor placement. But you must be aware of the equipment and manpower requirements for these large pours.
June 2002: To Improve Placement, Understanding Vibration Is Key
During the 1990s we saw concrete design strengths increasing in pavements, precast products, and throughout the construction industry. Greater strength, however, does not eliminate placement problems, and often makes them worse.
March 2005: Let's Talk About Really Big Slab On Grade Placements...
Watching concrete hit the ground at over a hundred yards per hour can be just plain exciting to a concrete guy. But after it's all over and the slab is sawed and cured, are we producing a better product?
August 2008: Placing Structural Concrete Under Winter Conditions
Placing concrete under winter conditions is difficult even under the best circumstances for labor, construction schedules, and the cost of construction. Winter conditions increase the level of risk for everyone, and maintaining good concrete conditions is a challenge.
December 2011: On the Bubble
