Location: Austin, Texas

Firm name: EEA Consulting Engineers

Project type, building type: System overhaul, school (college, university)

Project duration: 1.5 years

Project completion date: April 30, 2007

Project budget for mechanical, electrical, plumbing, fire protection engineering only: $77,000

Engineering challenges

Location and space constraints for the new equipment: The tower was occupied and existing equipment remained in use for duration of the project. There was limited access to the area where existing and new equipment were located. This area is near the top of the tower, behind the walls that support the clock facings.

Time constraint for the switch over to the new system: The two-week Christmas break between the fall and spring semesters provided the only period that the tower was not occupied. The transition from the old air handling unit to the new one was scheduled for that period, which meant that all aspects of the project absolutely had to be completed and become fully operational during the break.

Solutions

Location and space constraints for the new equipment: The solution was to remove a portion of the wall below the north clock facing to allow access. A new equipment platform and stair system was constructed to support and access the new equipment in the tall void space inside the top of the tower. A crane was used to lift the equipment and material into place as well as to remove and replace the 2,700-lb wall stones.

Time constraint for the switch over to the new system: This entailed close coordination between EEA, the owner, the subconsultants, and the contractor. All parties committed early in the project to meet deadlines and to quickly address any issues that might arise. As a result, the switch over proceeded smoothly and the tower reopened as scheduled. Following the switch, final installation was completed.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
