East Gable Wall Beam

The concrete has hardened and the forms have been stripped away.  Due to the stiffness of the concrete we were unable to get it to flow to the top of the beam.  Any addition of water to facilitate this would affect the strength.  Therefore we will cast the beam in two sections.  We will cast the top section when we complete the sanctuary roof.

East Gable Wall Works

We are fixing the bending beams in the east gable wall (East Gable Wall, East Gable Wall II).  Our solution required the insallation of a steel reinforced concrete beam.

We built a wooden platform to faciltate the works and removed the wooden beams as well as two layers of stones beneath the arched openng.  The wooden beams were replaced and the steel reinforcement for the concrete beams was installed.
