City of Fort Worth
Dear Mr. Mir:
In response to your request, DELTATEK ENGINEERING has conducted an on site
observation of this facility and recommends the following temporary repair work. As you
requested, the City desires to stabilize the roof dome at this time to prevent collapse of
roof into the digester basin. Therefore, the following recommendations address the
stabilization of the roof dome and permanent repair to the current condition. The digester
dome is structurally unsound and unstable due to failed support brackets. Consequently,
no personnel shall be allowed on the roof top. All gas piping shall be valved off or
isolated to prevent emission of gases into surrounding areas in the event of roof collapse
into the basin.
Temporary Stabilization Recommendation
• Evacuate combustible gases from digester container and vicinity of this facility
• Set up gas detectors and monitoring station during hot work (burning, chipping,
grinding, and welding)
• Remove roof;nSuI-atilon unli rvvfIng, m.,ter.;a1 to .-4..1 ..bstrate v-41

remove all support brackets and install structurally sound brackets
• Remove the existing sealant and install new sealant
• Touch up all disturbed areas by welding
• Provide construction services during renovation
• Review submittals �� -
