ER-POST - Concrete Precast System

The following are pictures taken during the erection of the ER-POST system on Bookmen Stacks, a for sale condominium of 45 units in Minneapolis, Minnesota. The building is 70’-0” x 160’-0”, and has nine floors above the parking. The floors are approximately 11,000 square feet.

ER-POST - Prestressed

An overall view of the ER-POST system. Note the parking is clear spanned with precast prestressed double tees. The truss bottom chord supports the second floor and the truss top chord supports the third floor, thus leaving the first floor completely open.

ER-POST - Building Shell

The top level trusses are in position. The floors of the levels below are in place. The erection system is repetitive which allows the building shell to be completed quickly, a major advantage in Minnesota construction.

ER-POST - Finalizing

The structure is near completion. All but the two final trusses are in place, and the precast plank will soon establish the two top floors.
