Learning the Language (Construcao)


A second unexpected trip to Pocone last week yielded another visit to the engineer who provided a list of materials needed for the foundation and concrete structural support. We were also able to return to the construction supplies store to get an exact quote. There are some discrepancies with numbers which we need to clarify with the engineer, but the quotes are pictured here to give an idea of the materials and approximate quantities that will be used. While this information is helpful in understanding local materials used and likely construction processes to ensue, we still have many more questions for the construction supervisor and engineer, both of whom we will be meeting with tomorrow. Eduardo Falcao De Arruda (Owner of Jaguar Eco Lodge and site of project) has also had much input and insight into the local construction and logistic processes and is recommending a construction supervisor (pedreiro) who has recently built two structures at the lodge. While we have been waiting to meet with the construction supervisor, we have been building detailed 3D models of the structure and roof system based on the materials that will be used as well as the local construction methods that we have learned about based on buildings we have seen, our conversations with the engineer, conversations with the construction store manager, and with other local well-informed building owners.

Here are some of the questions we have for the engineer and construction supervisor:

What are the extents of the slab? Building footprint? Breezeways? Roofline? Roofline, and then some?
What is the slab thickness?
Is there rebar or reinforcement of any sort in the slab?
What size rebar goes where? And how many – how many in the columns (1, 2, 4?) and how many in the bond beams?
What is the maximum spread for the columns?
Is there footing under columns? All the columns? What kind of footing?
If the typical dimension for a beam is 10 by 20 by 4m, then why is the beam drawn in the truss elevation 12 cm?
What happens between the bond beam and the door? – Brick? Netting?
What is the height of the bond beam?
What is the approximate space below the netting/window (even though this is flexible, it would be good to know what they were thinking in order to understand the estimates)?
What accounts for the width difference between the column and brick? Even if there is a stucco finish, there is a difference in width.
What is the dimension of the mortar joint?
What is the typical order of building?
What type of formwork is used?
What kind of tools will you (the construction supervisor) bring to the site? What tools do we need to get?
