Foundation Pile Caps

The next phase of construction started in full the last week of October. We are now working on the pile caps and short columns up to the basement level. There is currently about 120 workers on site. We should get up to 150 workers on site in the next few days. These will be the full time workers. Once we start doing larger concrete pours (slab pours) the number of workers will quickly increase during those days. By the end of November we anticipate being able to start casting the basement slab.

(Site overview)

(Pilings are excavated down to a set level - All by manual labor)

(Dry season just started so the water table level is very high - feels like it is dropping at least a couple inches a day right now though)

(Pile head breaking down to the desired depth - A 3" thick concrete slab is poured prior to breaking to make a platform for breaking and setting up form work.)

(Removing pile cap form work and installing the short column forms to the basement slab level)

(Remove water then back fill and compact around the pile caps)

(Evening work to make use of the cooler temperatures)

(Progress on the BBCB building - Second level is now completed up to the lintel height)

Nepal Vacation

It was great to get away on vacation for a number of days in Nepal. We spent 7 days trekking through the Annapurna sanctuary to Annapurna Base Camp (ABC), an amphitheater of stunning 7000 and 8000 m snow capped mountains.  We also enjoyed a few days of exploring the cities of Pokhara and Kathmandu, shopping, eating, visiting a waterwall/cave and paragliding (Jon).  We arrived back in Bangladesh during a multi-day hartal and tensions were high but we had no issues getting to Cox's Bazar and taking a sunset boat trip up river to Malumghat.  We have added photos of the trip that you can access by selecting gallery under the blog title or by clicking this link:  Nepal 2013 Gallery
The next phase of foundation work has begun  including pile head breaking, pile caps, and short columns.

Fall 2013

After a very intense period of time on the hospital construction site completing the piles, work has slowed down over the past couple of weeks.  The contractor is now off for the second Eid holiday but will be returning near the end of the month to start work on the pile caps (first layout and pile head breaking).  We have been stockpiling materials on-site (various types of sand, stone, cement, steel, etc.), building additional housing for the construction workers, trying to catch up on paper work and working on final design details. John M.,  one of our American Architects, is here on his 5th trip to help to finalize some of those design details.  It has been good to get some additional architectural input and history.  Jon and John M. made a quick trip to Dhaka and Chittagong to meet with our national architects, engineers and the contractor to discuss implementing some value engineering changes.  I have added some related photos as well as other random shots from the past couple of weeks (warning: there is a good spider shot at the end).

Piling Progress - Completed (378 of 378)

Today the contractor finished the last pile for the foundation work (378 pilings complete). There is now over 90 metric tons of steel and 44,000 cubic feet of concrete in the ground to support the building. As we start to build upward the progress will start to be much more visible vs during the pilings only seeing the site get built up with sand and mud day by day. We will now have the building laid out again for the pile cap and short column work. We hope to get a good start on this work for the basement area prior to the next Eid holiday mid-October.

Surfing Cox's Bazar

This past week we made a lot of progress on finalizing the site design and grading with Chris. During his time here I found out that Chris likes to surf, so it felt like an opportune time to give it a go down at Cox's Bazar beach. Unfortunately none of the expats on campus had ever gone to Cox's to surf before so we were a bit in the dark as to where to find the equipment, or if it even was available to rent.  Undaunted we set off anyway with high hopes. As we neared Cox's (about a 45 minute drive south) we started to call some contacts we have made during our time here and eventually a number Holly was able to look-up got us in touch with some guys that surf and who said we could rent a couple boards from them for the morning.

(Down a small road, then an even narrower alleyway we found the "surf shop")

(A few boards on the wall of this guy's family's living room)

(Showing off some of his surf trophies) 

The waves were great for a beginner for me yet still fun for a regular surfer like Chris. I was told they were 3 foot waves, but to me when they are coming at us they were breaking well over our heads (wave height measured from the back side). Overall they were quite consistent with a few minute lul to catch our breath as the tide was changing.

(Jon and Chris Surfing Cox's Bazar)

(Walking back up the beach after some good waves with the one surfer we met out in the water.)

The shoreline is relatively straight and sandy for about 130 kms so there is a load of space, although it's not a problem as we only saw five other surfers on this Saturday morning over the 5 kms of the main cox's beach we could see.

(Jon heading in after a few hours of surfing)

(The Ocean was a few minutes drive from the shop so took our boards on the truck vs the cycle rickshaw they typically use)

We could have easily spent more time out on the water, but we also had to pickup John, our American Architect, from the Cox's airport and get back to Malumghat for a team meeting. From what I hear it sounds like September/October has the most consistent waves.  I'm always going to be looking for someone to surf with now whenever I can get away from the site. Hopefully we have some more short termers that are into it. We are still working on how Holly could do it without drowning in all the clothes she is suppose to wear.

Only 36 foundation piles remaining of 378 total (90% complete).

Project Material Testing

Last Thursday, after loading the truck with various types of sand, stone, bricks and cement, I (Holly) headed to Cox’s Bazar (with a translator and a driver) to visit a government materials testing lab.  First stop was the bank, or rather banks.  Our first choice ATM was out of money (the security guard let me try for a while before informing me) and the second choice machine spit out my card, but we eventually found success downtown.  Armed with some cash, we headed to the lab.

We sat and chatted about testing options with the lab rep for some time and filled out the necessary documents for sieve analysis and L.A. abrasion tests for the aggregate (sand and stone) and compression strength tests for the bricks and cement.  I also purchased some cylinders (for concrete samples during construction) and a slump bucket.  Part way through the meeting my translator asked me if I was the elder child and was amused when I said yes.  (Things are very relational here).  Apparently, he thought I was taking charge, which I took as a compliment (otherwise I would have been there all day!) What do you think about this Katie and Zach?

Jon and the Contractor used the new cylinders today to sample the proposed mixtures (cement/sand/stone) for 3,500 psi and 4,000 psi strength concrete which will be used on the remaining building structure after the 2,500 psi piles/pile caps are complete. 

(Testing various concrete mixtures to ensure proper material/mixture strengths)

Jon was also in Cox’s Bazar on Sunday to pick up Chris, a civil engineer from the US who has come for a week to help with the site plan (confirm finished floor elevation, drainage, grades and location of roads, etc.).  He has made great progress already and has a similar work ethic to Jon (ability to work a lot of hours) which is especially impressive after the long journey!
