Foundation Slab

It was an exciting time at the site on Thursday! Starting at 8:30am, I got to see four large cement trucks navigate the narrow streets into my driveway to pour out the slab for the foundation.

The pour begins:

There's no turning back now! We can't even drill into the concrete after it has set because it would risk puncturing the embedded piping. Also of note in that picture is the 40ft coil of copper wire (lower right) leading to a Ufer ground setup in the foundation. That'll hook into the electrical box of the house. Here you can see the contractor directing concrete from the tube in the sky:

At the recommendation of the architect, we had "Seattle Sidewalk" pigment added to the mix to darken the slab. He said that concrete color matching is an inexact science, and he's had good results with that color in the past. It looks good in the photos!

Once the last concrete truck drove away, the troweling process began:

I was told they were out there until around 6pm. I can't wait to see what it looks like after it has cured! Next up are the retaining walls for the foundation.

Foam, Rebar, and PEX

After the gravel, the next step was to lay down a vapor barrier and cover the entire footprint of the foundation in a 2" thick layer of foam panels. 

Next step - take rebar...

...and tie it up in a grid.

Those red tubes you see there is PEX for the hydronic heating system. It's tied to the rebar.

All the pipes feed into the mechanical room of the house:

After this work gets approved by the city, it can be buried in 8" of concrete. This will hopefully happen later in the week!

Grading and Gravel

With the side sewer line installed and buried, it's time to focus on the foundation of the house. There's quite a bit that goes into creating it. The first step was to flatten and compact the ground. Next, the plumber installed the sewer pipes that lead to all the drains in the house.

After that, they brought in and compacted a 12" layer of gravel across the entire surface. This is to add stability and proper drainage to the ground.

While I was on site, I saw them prepare for the next step:

They're unloading 2" rigid foam panels. Those will be laid across the entire surface of the gravel in order to insulate the foundation from the ground. This will prevent heat from escaping the house through the foundation and will make the bottom floor seem more like a normal room, unlike a typical cold basement.

That truck also has a bunch of rebar. This will be installed above the foam layer to help strengthen the 8" thick concrete slab.

I have a sewer!

Not much has changed on the lot itself since the last post, but one big issue has been resolved. I started talking to the neighbor to the north of my lot about running a sewer line through their backyard. They were a little nervous about it, but they ended up allowing me to do it in exchange for a cash offering. What a relief! The sewer is still around 3x over budget, but it would have been closer to 6x otherwise.

With a signed easement in hand, my plumber went to work. This is the approximate path that the sewer line will take:

It's a bit of distance to cover, but it is all downhill and doesn't share any plumbing with the neighbor's house (other than the y-joint). First, he had to locate the side-sewer connection going out to the street.

From there, a trench was dug and a 6" line was installed along the edge of the neighbor's lot.

Here it is taking a corner:

..and another corner along the backside of the neighbor's property:

And finally, it needs to go uphill into my lot:

Next week should pick up again. We have picked out a new sub-contractor to finish the foundation work. My plumber will also be running the lines underneath the foundation and burying the pipe once it has been approved by an inspector. I can't wait for this phase of construction to finish.

Hole in the Ground

Progress is going slower than planned. There's a contract dispute between the foundation sub-contractor and my GC. Apparently, the sub-contractor had bid on the original set of plans, and not the one with the revised foundation. They were notified and given the revised plans 2 weeks prior to signing the contract, so the error wasn't on our side. I hope that this messy situation will be resolved soon.

In the meantime, in order to move the project forward, my contractor hired someone to haul out 45 truckloads of dirt to make room for the foundation. The geotech didn't allow for the existing soils to be used as back-fill, so that export was a major unexpected expense. I will probably need to go to the bank to re-negotiate the foundation-portion of my loan to account for all these new expenses.

Here's where we are so far. The south retaining wall is in, but there's no drainage or back-fill on it yet:

We also have a huge hole in the ground now. Here's what it looks like from the driveway:

A close-up:

Here it is in comparison to the duplex:

It's kind of hard to judge scale in the picture, but that is about 8 feet deep! One good thing happened - the owner of the empty lot adjacent to mine let me use his lot as temporary dirt storage. We promised to clear it out once the foundation was completed.

Driveway/Foundation Update

So what's happened since the retaining wall went in? Well first, by May 19th, they had taken out the existing driveway, graded it, and put down a layer of gravel:

A temporary slope was created to allow access for machenery:

Using the machinery, they cleaned out the lot and removed all vegetation:

By May 26, they started creating forms for the foundation. Here's the continuation from the retaining wall:

Looking into the lot from the driveway:

Forms being prepared for the other side of the foundation:

Here's the start of the retaining wall holding up the rear portion of the driveway:

Fast forward about two weeks to June 7th, and things start taking shape. Here, you can see the temp power pole and also how the retaining wall flows into the foundation:

That indentation is for the bridge to the entry of the house. Here's the same thing viewed from the other side:

Looking into the lot from the driveway:

The foundation wall connecting the two sides won't be put in until the basement is excavated. This way there is still room for digging equipment to get in and out. Here's what it looks like from the other side of the lot:

And finally, as a result of the failed sewer negotiations, I had to do something with the neighbor's crummy, and now under-cut retaining wall. The least expensive solution to prevent his wall from collapsing was to build a short concrete retaining wall and position it as close as possible to the edge of the shared driveway. Here, they're preparing the footings for the new, short wall:

I'll probably try to hide his wall with vegetation or something so that it doesn't look too out of place.

Sewer Negotiations

One thing I had to deal with over the last few weeks was what to do with the sewer line. During the bidding process, all the contractors had assumed there was a stub-out for a sewer line already there for the lot. From what I understand, this is a safe assumption to make. Unfortunately, there is no sewer hookup to my lot! There are two ways I can get rid of sewage. 

1. Run a sewer line about 100' up the driveway, tear up the street to tap into the main sewer line, and repair the street (all at my expense with city labor). I would also have to install a pump in the house to pump the sewage uphill. All this is very expensive ($20-30K).
2. Run a sewer line downhill along the north side of the neighbor's lot and hook into the side sewer at the sidewalk. This is much easier and cheaper (~$5K), but requires permission and a side sewer easement from the neighbor.

The decision was obvious. I first contacted the neighbor about tapping into their sewer line and they seemed to be fine with the idea. Fine, that is, until they talked to their attorney friend. Their friend vehemently recommended against such an agreement. Their first argument was that they incur some risk of me potentially clogging their sewer line. This isn't an issue as I would be bypassing their sewer lines and forking into the existing city line. They also said that they may have difficulties selling their duplex with an easement on the title. In my opinion, this isn't a big deal and it's apparently done quite often. If I were buying a house, the sewer easement would probably be the last thing I look at. 

A while later, a second issue came up. The same neighbor has an existing retaining wall on the south side of the driveway. It's about 60x3', handmade out of concrete scraps, and somewhat falling apart. They expressed interest in replacing the retaining wall with something nicer, but quickly disagreed when my contractor quoted them $6500 for it (it's an $8500 job). Since I have to undercut their retaining wall with my new driveway, that creates another new expense for me to try to support their structure and keep it intact. *grumble*

To try to sweeten the deal, I proposed that in exchange for giving me a sewer easement, I would replace their crumbling retaining wall with a nice poured concrete wall, equivalent to the one I have on the other side of the driveway. I also offered to cut down and dispose of the large bush in their backyard (a $600 value). This is a win/win situation for the most part. I don't spend nearly as much as option #1, and I get a nice driveway with proper retaining walls on both sides, while they get a new retaining wall and their bush taken care of. With this new offer, the neighbor gave me verbal agreement that he'll do it.

But not so quick! A day or two later, he had talked to his attorney again and had come up with a new list of demands. They wanted a set of proposed plans for the new retaining wall, a timeline, an indemnification agreement, and for me to pay the attorney's legal fees. When I had my architects draw up plans for the retaining wall, they also asked for the wall to wrap around the front of their duplex (probably an extra 2-4K expense). This was quickly starting to get ridiculous. I pushed back on the retaining wall additions and on the legal fees. Their attorney also suggested he could write up my end of the agreement (for a fee), which was ethically questionable.

Despite the already bad taste in my mouth from all this, the neighbor did still seem willing to move forward, and knowing that I could buy a car with the money I could save, I continued negotiating. Several days later, the neighbor came up with a new concern. He was worried that the sewer line would somehow disturb the cinder-block foundation to his duplex. This concern was totally unfounded, so to ease his mind, I had both my contractor and a foundation expert come out and say that this will not affect the foundation. Even with that assurance, he wanted me to sign something in paper that basically said that if his foundation deteriorates between now and the end of time, I would be responsible for repairing his foundation. In the words of Will Smith, "Aww hell naw!" Is this guy going to try to extort me? I only got to steam about that for an hour before he called back to say he's completely backing out of the agreement. Well thanks for wasting everyone's time!

Back to option #1!

In an effort to perhaps share some of my new-found expenses with someone else, I emailed the owner of the neighboring empty parcel and asked if he was interested in having me run utilities to his parcel and split the sewer cost before the driveway goes in. It would be a great selling point for that lot, and the future owner wouldn't have to tear up a brand new driveway to run utilities. He agreed to pay to run water and gas, but when he heard the estimated price tag on the sewer, he couldn't afford splitting the cost on that.

So in summary, I get no help from anyone and have to absorb all the extra costs, which are guaranteed to be significant. I'm forced to do option #1, but I will run a 6" line with a T-junction at the end of my lot in front of the house. Once the driveway is paved over, anyone who purchases the adjacent lot will have no choice but to hook up to my sewer line. When that time comes, I'll keep it simple and grant easement to my sewer in exchange for half of my sewer construction costs (whatever that ends up being). As for the south retaining wall, I'll build out a short concrete retaining wall in front of the neighbor's old one - just big enough to prevent the existing one from falling apart. I'll plant some shrubbery or something behind the wall to alleviate the eyesore.

How will I pay for this? The bank is of no use. A construction loan can't be re-negotiated, and anything over-budget has to be payed for by the borrower (me). If the money I saved up since March doesn't cover it, I'll probably borrow some from my parents or tap into my 401K (with penalties). Let's hope it doesn't come to that. Either way, I will be covered. I'm told that excavation/foundation work is the worst part of construction and the most likely to go over-budget. Once I'm out of the ground, it should be smooth sailing. At least I'm glad I'm no longer in decision-making limbo and can move forward.

Lessons learned:

• Lawyers bring out the worst in people
• Nothing's guaranteed until you see it in writing
• Don't count on anyone helping you out, even if things are in their favor
• Sewers are expensive
• Always have extra money laying around
