We are currently a fee days behind schedule on this project due to the bad weather we have been having in the area recently. Fortunately the site has not suffered from the flooding that there has been in some other areas in the region, but nevertheless, the rain has still had an impact. However, we have now completed all of the first stage columns and are up to ground level. Today an excavator back filled all of the footing holes, so moving forward with the project, the rain should be less of an issue. Tomorrow we will begin to install the steel cages for the grade beams, which we have been preparing under cover during the rain.
We have completed an initial architectural concept for a 7 storey condominium to be built in Vientiane, Laos. The ground floor will consist of a reception, a small shop, gym and parking. There will then be five floors of accommodation units of various sizes with either one, two or three bedrooms. The top floor will house services. The general appearance and style of the exterior has been agreed with our client, but we are now working on refining the interior layouts a little, which will inevitably lead to minor alterations to the exterior, in terms of window positioning and such like.
We have just begun work own our latest construction project in Nong Wua So district, near Udon Thani. Yesterday we marked out and excavated the footings. We used a large excavator, which makes the process very quick, however there is then a certain amount of manual work to be down to neaten up the holes and make sure all footings are to the correct depth, which is what we have been doing today. We have also added in the initial base layers of sand and concrete to the holes, onto which the main footings will be poured. Tomorrow is the lucky Buddhist day on which the first two columns will be erected. The final completion date for this project is March next year, so 6 months from start to finish. As we are nearing the end of the rainy season now, we should not have any major delays in construction.
We have completed the basic concrete frame for the garage and are soon to begin adding the steel roof frame structure.
We have been somewhat at the mercy of the weather, and pile driving has been on hold for a number of days. Fortunately, with such a big project, there a a lot of jobs that can be done in parallel to the pile driving, so ultimately our schedule should not be adversely affected. Currently, we are preparing the hug he number of steel reinforcement cages that are required for the footings, columns and beams. We are also fortunate that the site is so large and we are not short of space to store these cages. One potential issue of stop piling these components is the oxidation (rust) that can occur if they are exposed to the elements for prolonged periods. The steel re-bar has already been sprayed with light oil once on leaving the foundry. However, through handling from foundry to stock holder to site, and then then cutting and forming it into the cages, some of this oil has inevitably worn off, exposing it to the risk of rusting. To prevent this, once complete, the cages are sprayed with light oil.
Another task on this site was to reposition the main access point into the site. First we had to obtain the necessary permission from the local government department, as there is a government owned strip of land between the plot and the road. Once approved, we installed the necessary drain pipe, as required, and have built up the new road way. We shall allow this to settle for several months before applying the finished road surface, using the existing access in the mean time.
After a delay due to extremely heavy rain and bad weather, pile driving has now recommenced and is going very well. In fact, despite the delay, we are still on target to complete all pile driving on schedule. There are many issues that can be encountered during pile driving, from hitting impenetrable ground and fractured piles, to simply slow progress due to ground conditions. However, in this case, we have not encountered any such issues.
While pile driving is underway on the main house on the elevated section of land, we have also been busy constructing the separate garage unit on the lower lying land. We have already constructed footings and grade beam and are now preparing the reinforcement structure ready to pour the concrete floor. As the floor will be taking a relatively high load, we are not using pre-cast slabs, but have back filled with sand and will be casting a heavily reinforced slab in place. In casting directly onto sand, it is important to ensure that the underlying layer is adequately compacted. If not compacted this layer of floor support may settle over time and 'sink away' from beneath the floor. This may then lead to cracks and other structural weaknesses in the floor slab. With the garage, we used a mechanical compactor on the supporting sand to minimize problems in the future.
