A local church had a parking deck that needed repairs. Richmond Primoid was brought in to make various structural repairs to parking deck. In addition, 6,000 sq.ft. of parking deck area had to be removed and replaced with new concrete. Expectations were high and several goals were set and then met.

  • Total project needed to be complete in 90 days.

Richmond Primoid and W.J. Rapp teamed up to meet this challenge.

  • Second Floor 6,000 sq. ft. area of concrete had to be removed and replaced.

This required the removal of all underside electrical and fire protection.

This also required design of steel support for the front wall of the existing building to support the wall and building before floor could be removed.

Entire underside of the second floor was scaffold.

The upper floor was cut into pieces that could be carried out to dumpster.

Headroom was only 7 feet tall which limited access.

  • Steel beams Removed and Replace

Upon removal of the floor, deteriorated encased steel beams had to be removed and installed where needed.

R.S. Harritan provided structural steel work to allow the concrete steel beams to be incorporated into a new structural slab.

  • New Concrete Slab

The slab was poured with a 5,000 psi mix that was reached in 7 days.

The concrete had a corrosive additive added.

  • Meet limited time frame and access demands

Due to the location of placing concrete…. trucks and a pump truck the pour had to take place on a Saturday morning at 5:30 a.m.

Upon completion of the pour and after the 7 days break shoring was remove.

Upon completion of the pour and after the 7 day break shoring was removed and restoration fo the electrical and fire Protection.
