Final Building Foundation Pour

We completed the fourth and final building foundation pour yesterday, and the crew worked quickly today to disassemble the forms on the interior walls and columns, so that the excavation contractor can start importing fill material tomorrow morning. We used around 25 cubic meters of concrete, but it was a time  consuming pour because it was all in small, constrained spaces as you can see from the photos below.

The building is starting to take shape as the exterior wall location gets defined and the elevator / stairwell area becomes more clear as well. After tomorrow, the fill material will be imported, compacted and rolled, and brought to within 10 centimeters of the future slab on grade elevation. Then we will excavate for the Ground Beams that tie the columns together, lay the steel in the trenches, place the wire mesh / grid on top of the compacted fill, and pour the slab and the Ground Beams at the same time.

While the excavation contractor is doing his thing over the next 4 days, the crew will be working on the reinforced concrete retaining wall that will separate the site from the future street along the north (front) elevation. The total height of the wall will be 5.5 meters (~18 feet) with a footing that's 2.6 meters (~8.5 feet) wide. Here's a picture of the crew clearing the area for the foundation steel, while two others start setting the forms to hold in the concrete from the next pour for the retaining wall foundation. More on this to come in the next couple of posts.

Second Foundation Pour

The second foundation pour took place a couple of days ago, and everything went smoothly. We should have one more pour that includes the stair case and elevator shaft foundation, before starting to form the columns and prepare for the fill material to be placed below the slab on grade.

Below are a few photos of the rudimentary methods used in preparing and erecting the timber forms, which I continue to find strikingly old fashioned and ingenious at the same time:

(short footing edge formed with dirt and rocks)
(braces for the forms anchored with boulders)
The main element of support the crew needs during this stage is ensuring that the column and wall centers are accurate compared to the axis given to us by the surveyors, that the spacing and proper thickness of steel reinforcement bars are used, and that the layout of the steel for the column necks is correct. 

(close up view of one of the footing forms, still missing steel)
(forms completed)
(calculating steel reinforcement beam spacing and locations)
We calculated that we would need around 45 cubic meters of B300 concrete, placed the order and called the geotechnical engineer to schedule the testing crew again. They showed up a few minutes before the mixers arrived and took a sample from each mixer batch to test. After the 5 footings were poured, we ended up using 42 cubic meters of concrete.

The next few days will bring the forming and steel setup for the stairwell and elevator shaft, the final foundation footing pour, the forming of the column necks, and preparation for construction of the 5.5 meter tall concrete retaining wall between the building and the street.

Foundations & Concrete

Work has been progressing relatively quickly at the site for the past week. Once the marks for the foundation axis were established, the crew went to work setting up forms for the foundations that will support the building columns. I find myself constantly impressed at how old-school the methods used to accomplish this work are: all the measurements (after the surveyors gave us the initial markings) are taken with a tape measure and the crew uses string, a level and spray paint to mark form locations, all the elevation levels are taken with a clear hose filled with water, then measured from the benchmark set by the surveyors on the 'bracelet' fence surrounding the site, wood boards are fastened together using metal wire and supported by large rocks and dirt on the outside edges.

Keep in mind there have been only 4 workers on the site this whole time, we only added a fifth two days ago to prepare for the pouring of the first layer of concrete (the Blinding, called 'nadaaf' in Arabic, or clean layer) which will allow us to set up our steel reinforcements on a uniform, horizontal surface.

Below are a few photos of the site over the past few days, showing various stages of development:

(workers and foreman discussing progress)

(setting a new mark for the edge of a concrete form using string and a level)


('bracelet' on the right and forms on the left, before cleaning the pour area)

(the forms taking shape)

(areas around the forms are getting cleared of debris)
In addition to the construction oversight, project budget management and scheduling, I've enjoyed learning (or remembering) how to perform some of the engineering calculations required for the ordering of materials and supplies. We had our first order of reinforcing steel arrive at the site today:

(delivery truck unloading steel)

(steel of various thicknesses and shapes, based on the foundation design)
After finalizing our price negotiations with the concrete plant yesterday, the time came to receive the first batch of concrete for the nadaaf areas that were ready. Based on the surface area we calculated and a 10 cm thickness, we ordered 15 cubic meters of concrete with +/- 2 cubic meters that were allowable for return if need be. The mixer trucks carry 9 cubic meters each, so we had two mixer trucks and a big (52 meter) pump truck come out to the site today:

(each crew member knew what to do, worked very efficiently)

(tough job of guiding the erratic pump hose manually)

(foreman giving directions on depth)

(almost done)

(foundation base is in place)
We can't forget the floor of the new site bathroom (not quite portable), so that there's a flat surface to stack the concrete bricks on for bathroom walls:

(barrel with sawed opening in the middle)
And here's the site after the week's work was completed:

(1 week down, 76 to go)
The crew started right back up setting forms for the remainder of the foundations that will get poured with the next concrete order. We used 16 cubic meters this time around, quite close to the estimate we calculated. Next week should be more of the same, but we'll get closer to pouring the actual foundations and ground beam, which will allow us to set up the column necks then fill around them to get to the finished slab elevation for the bottom of the second basement floor.

The Time It Takes

Two months into our stay here, and I'm just now starting to get used to the pace of life in Ramallah. My initial frustrations at the slow pace of business and the inevitable delays we run into at every turn (which I was perceiving as lost time) has been replaced with the relief from the never-ending pressure of the daily grind that characterizes the rat race in the US, and the joy of spending more time with my family. I'm re-learning how to enjoy the cup of arabic coffee or mint-infused, sweet black tea served at the beginning of every meeting, the expectation that you start the meeting with discussions about anything except the business at hand, and the many other cultural norms (or "isms" as my brother would say) in the Palestinian society.

This is just how long things take here, for better or for worse, depending on how you want to look at it. I admit that I'm getting anxious to start construction, because we've had the site excavated and contractor-ready for at least 4 weeks now. But things happen for a reason, and today we find ourselves:
  • At the conclusion of partnership negotiations with a builder to to set up a contracting company and perform the development work on the project ourselves, improving the proposed Return On Investment for the overall project. This after coming within hours of signing a contract with a different, more expensive General Contractor who would not have provided the same synergies to the group.
  • Under contract with a graphic design artist to create a design for our new website, newspaper ad(s), project sign and (possibly) a billboard ad.
  • At the end of electric wiring, insulation and sheetrock, and window installation at the mobile office. Painting, fixtures and furniture remain to be coordinated over the next few days.
  • Having a much better understanding of our ability to finance this and future projects with the banks' assistance, and with the framework for a strategic plan for our operations for the next 5 years.
The plan as of today is to start work at the site next Monday, after the crews we hired wrap up work on another project, then the clock starts ticking. We budgeted 45 days for the first level, and 30 days for each floor after that to complete the 'Adem (frame) phase, around 8 months total for the 7 stories. the Tashteeb (finish-out) will dove-tail into it and the final two or three floors will wrap up 3 to 4 months after the framing of the roof floor.

Meanwhile, here are a few photos of the only physical activity going on at the site ... improvements to the shipping container / site office:

(frames added to attach sheetrock onto)

(work in progress)

(how many Palestinians does it take to put up a panel of sheetrock?)

(the new view from inside the - now smaller - office room,
after partitioning an area for a guard's quarters / tool storage)

Hopefully, next time I post it will be with pictures of the set up for foundation pouring. Or as we say here in Ramallah: Insha' Allah.

(With thanks for my brother for inspiring the title to this post from a song off his new album).

More Rain and Sunset

We've had a few more rainy days in Ramallah, and it's given us a chance to finalize our agreement with a contractor and follow up on a few more administrative items, namely:
  • Prepare a preliminary wastewater study to figure out the best way to connect to the city's wastewater system, and coordinate a service extension request with the city. We still need a consent letter from the neighbor who's property we'll need to go through, as well as a route survey just to submit our application to the city. I'm sure I'll post more about this in coming days.
  • Coordinate meetings with a graphic designer to help us with our marketing needs, including a new website design, a brochure, print ads (we're planning on a couple of newspaper advertisements in the coming months), a site / project sign design and possibly a billboard.
  • Finalize arrangements with the subcontractors who will work on the interior finish of the site office, arranging for electricity, insulation and sheetrock, and office furniture.
  • Preparing a project budget and schedule, as well as a few development scenarios to get an idea of our cash flow situation for the coming months.
  • Interview contractors for the second phase of the development. Typical construction here takes place in two stages, the building frame (called 'adem, or "bones") that includes the reinforced concrete walls and the stone facade, and the finish-out (called tashteeb) that includes plumbing, electrical, interior walls, paint and wood framing, metal work, flooring and finally the kitchen and bathroom fixtures.
There's plenty to keep us busy, but I'm excited about getting the 'adem contractor signed up and getting the construction started. Weather forecast calls for a few more cloudy / rainy days up ahead but I'm hoping we'll start work on the foundations by the middle of next week.

In the meantime, I thought I'd post a few more photos of the diplomatic subdivision from the outside looking in, as seen from the west Ramallah neighborhood of Al Tireh. You can see the massive amounts of earthwork used to nestle the subdivision into the hillside:

(diplomatic subdivision - click on image to enlarge)
For someone who values the natural beauty of this place (and all other places as well), it's sad for me to see the land planners' apparent disregard for the topographic constraints they're working within and choosing not to design with nature. We're probably an even longer way from introducing biomimicry to the design industry. 

I took the next set of photos last week on my trip to that subdivision, and I was struck by the size of the retaining walls looking out from one of the villas. These walls were probably 15 meters tall in some places (~50 feet) and we were told that the builders were asked not to fill behind them because the weight of the fill material would be too much to design support for, so instead they were using a reinforced concrete floor at a higher elevation along the wall, then only filling above that for the uphill villas. Here's a set of three photos that I crudely merged to try and give a sense of the scale:

(retaining wall at diplomatic subdivision)
As for our site photos, I have a couple from the blacksmith's visit to our site office to install a door and windows:

(new office door and windows installed)

(the view from our future office)
Speaking of views, I'll end with a sunset view from a hilltop a couple of minutes away from our project site:

The Diplomatic Subdivision and Housing Finance

As part of our process for interviewing subcontractors (a plumbing sub in this case), we visited the Diplomatic Subdivision today. It's a residential subdivision just on the outskirts of Ramallah designated for members of the Palestinian Authority or people associated with the Palestinian Government, and the level of luxury evident in these houses made it easy to forget that the people this government is representing are living under military occupation.

Here are some photos from the trip:

(street view of the villas)

(looking downhill, with apartments at the end of the street)

(the views from the balcony of one of the villas - looking towards Ramallah)

(another balcony view - another new Master-Planned Community in the foreground)

(master bathroom inside the villa)

(master bathroom fixtures)

Development is everywhere you look. From what I've been able to gather, condominium regime laws were introduced in 1993 and really facilitated the exchange of apartment ownership, then the mortgage system began entering the West Bank (apparently brought in by Jordanian banks investing in the Occupied Territories around the year 2000), and the elements for a housing boom were in place. 

The start of the second uprising (Intifada) delayed the start of the housing boom, but as soon as the political situation started stabilizing the supply of apartments / condos began to increase and demand is projected to be at 7,000 - 8,000 units a year at a minimum (other figures I've read are as high as 40,000 per year for the next decade).

A banker colleague of mine said he read in a study that there is close to one billion US dollars "under the mattress" in the West Bank. That's roughly one seventh of the cash available to all the banks in the West Bank, and it's starting to come out from under the mattresses. The people of Palestine generally have strong saving habits, and 35 years of pent up demand are finally finding some available supply to start satisfying them.

Mortgage financing is now available through Western finance vehicles, as well as through Islamic finance institutions, and the usual terms these days are 15% down payment and 20-year mortgage. There are even institutions like the Palestine Mortgage Housing Corp. that offer 10% down payment and 25- year financing. 

As for land prices, the desirable areas have plots that are 1 dunum (roughly 1/4 acre) selling for $1M ... just the land, no improvements on it. That's on the high side, but the average is around $300k-$400k per dunum in Ramallah.

Here's another view of west Ramallah taken from the Diplomatic Subdivision. Note the expansion down into the valleys:

(view towards Al Tireh neighborhood. Note the street cuts and all the fill material dumped downhill)

(neighboring property development - again note the fill material dumping mentioned in earlier posts)

As for our little project, we finally got the water main extended into the proposed road, and the temporary water meter installed. We also got our electric meter tested and approved today, so we can officially extend power to the construction site.

(our proposed road filled back in after waterline construction)

Tomorrow the blacksmith comes out to work on the mobile office, adding windows, doors and locks. Now all we have to do is find a contractor and we can get started!
