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…

Building our house in the Philippines. January 31, 2010.  We’ve just ended the first two weeks of construction.  We’re generally pleased with the progress.  We have thirteen workers on our crew including two foremen.  I’m on-site most of the time so there are three “bosses”. So far we’ve spent about $8,000 including “soft costs” (architecture, permits), equipment, materials and labor.  We’d like to keep our total cost to about P15,000 per square meter or about $50,000 for the 150 square meter house.  Every day one faces decision which affect the cost.  Should we use 6″ block for a stronger house — it only costs a P30,000 pesos more!  Should the concrete floor be a bit thicker to reduce the chance of cracking?  Should we use 1/4″ thick angle bar in building our roof trusses or the thinner…
