Progress

We have had a good push on the excavation of both phase I and II with the helping hands of the GIEU crew. Large septic pits have been dug and the trenches and footings are near completion. All the while, the in-ground brick work that acts as both a structural footing for the infill wall system (tijolos) and a form edge for the interior slab has been completed on Phase I. Excavation cut from the septic and structural systems digs has been reused as fill in order to reach an FFE (finished floor elevation) that is consistent with the existing house. Infrastructural columns of rebar (ferro) have been built and installed. They are set in concrete footings (40x40x60 cm) and braced to establish an accurate stub out at the footing. Rebar above the footing will be manipulated at a later date in preparation of column formwork. The production and process of building and setting columns has been one of invention, correction, and common sense. Local knowledge and advice has been graciously availed to the crew and employed in most cases. It is sometimes the case that we utilize different tools or techniques than suggested as our own experience prevails in the decision making process. It is also common that suggestions vary from pedreiro to pedreiro (construction managers) and the locals. As it stands now we are moving vertically out of the ground with the main structure of the interior structural frame and setting up for the veranda brick work to begin. Nights are often spent drawing details that have evolved, discussing strategies for organizing a large unskilled labor force, and deriving cut lists for materials and a lumber package. We met with our local lumber supplier/millwork and discussed the derived cut list for the roof system (four structural trusses in the north/south direction that carry three beams (vigas) in the east/west direction, that carry all the rafters (caibro) in the n/s direction that carry all batons (ripom) in the e/w direction, on which sit the dry stack roof tiles). We were able to get a look at some of the vigas that have been cut for our job and so far the cuts look good and straight (reta). The vigas are being milled at 6m lengths and are coming from a local tree species called Piuva, which is a dense hardwood. The rafters will be of the same species at varying lengths and the batons will be of a softer species due to the amount of nailing involved to secure it to the rafters. All other materials are being delivered at a steady pace at one to two deliveries a week. We expect the deliveries to slow due to the fact that much of the necessary materials are currently on site. Occasional trips to Pocone are used to blog and pick up some needed tools and materials and this trip we will swap out the motor for the concrete mixer that had never operated properly.
Plumbing stub outs for in ground wastewater are being dimensioned and two options for water delivery are being weighed. As for the luxury of a concrete mixer, the primary generator is now up and running but the motor on the mixer is and has been in no shape for operation since it arrived on site. All of the concrete mixing remains on ground. Our current water supply for mixing concrete and mortar is coming from an existing well that was at one time the source of water for the existing house. Initially we lowered buckets into the well but have since moved up to a new manual hand pump that operates as if it were as old as the well. The water systems team is currently working on a bio filter that is made up of varying sizes of aggregate and sand that is sifted through a series of meshes that they brought with them.
General Notes:
_It is this week that Brasil was knocked out of the World Cup by Holland. It is a disappointment to say the least.
_The daily schedule for the design team (John, Nisha, and James) is now 6am-12pm 1pm-6pm
_Laundry gets done rarely and often only when it is absolutely necessary. We have all squeezed it in this week.
