Dunn Center Building Concrete and Canopy Improvements

Demolition of existing sidewalk ramps as noted and replacement of demolished concrete ramps with new City of Houston approved constructed ramps. Per direction from CoH inspector, reconstruct curb ramps to be 5 feet wide with 5'x5' landings at top and bottom. To comply with City of Houston ramp details dated July 2020, ramps are to be 1:15 maximum slope, which will result in longer ramps than previously designed. The landings will taper into the existing pavement at a 15-degree taper. See the attached updated design drawings for updated demo, layout, grading, and details for the reconstruction of these ramps. Some sections of sidewalk to reconstruct are extended in anticipation of new drainage in Mark Crosswell Jr Street. The drawings for work in the City of Houston ROW are still in review with the City at this time, but the anticipated work is reflected in these drawings. Construction of walk way canopy connecting existing Harris County Psychiatric Hospital with the new Dunn Center Building. Canopy construction includes demolition, concrete, electrical, canopy, landscaping and other miscellaneous items required to complete the construction in the noted documents.
