Earthquakes When we hired the engineer to design our house we were aware that the Philippines was included in the “ring of fire” earthquake zone and that our part of Panay Island had experienced a magnitude 8.2 earthquake in 1948.  In 1948 the island was much less developed.  Doubtless all or almost all the hollow block buildings on the island were built after 1948.  The 1948 quake damaged or destroyed. …

Splicing error in roof beam rebar Our Philippine house building project: concrete roof beams.  This photo shows the 16mm rebar framework for the concrete roof beam which is supported by the columns and in turn will carry the considerable weight of the roof structure. For that see http://goiloilo.com/our-house-project-welding/ . A visit by our engineer confirmed a problem with the arrangement of the rebar in the beam.  Rebar comes in six meter lengths.  As shown in the photo, the workers spiced all the rebar in the center of the span.  The engineer directed that splices be staggered with no splices at mid-span in the bottom rebar and no splices at the support columns in the top of the beam. Everything you see above will have to be taken down and redone.  Our plans lacked a rebar splicing plan.  This has caused endless required corrections…
