On the way to the construction site this morning, I was shocked to see an old friend lying dead on the side of Sudbury Road. Bruce, an extremely large male beaver, was a frequent visitor at the River House. When our site supervisor first saw him lounging on the ice he mistook him for a small black bear, which was an easy mistake to make given his massive size. His tail slap was loud enough to make you jump out of your shoes if you were close by and I think he enjoyed the reaction. Even though he did fell a favorite dead tree that was a popular and very photographic bird perch, I was very fond of Bruce and will miss him. When I returned from the site on the way to my annual physical, Bruce was gone. Perhaps animal control had picked him up but I am left to wonder if someone saw the potential for a magnificent beaver fur and seized the opportunity.

With our two geothermal bore holes completed and a 300-foot U-shaped pipe grouted into each, the next step is to connect the vertical loops to each other and then to the house. The crew excavated around the bore holes to a depth of 4 feet and cut off the steel casings at that depth. A similarly deep trench was made between boreholes and to the foundation of the house where the supply and return lines enter through two holes drilled through the foundation wall. The pipes from each bore hole are connected in parallel and then to the house from the midpoint of the parallel connection (to promote balance flow to each loop). A strip of metal tape was placed over the pipes so they could be located in the future and the trenches were backfilled concluding all the outside work for our geothermal heating and cooling system.

Nico spent the weekend in Denver putting on an amputee soccer clinic. Essential to building the US program are outreach programs such as this which bring young players into the sport. While in Colorado, he connected with his high school buddies Greg and Cray.

Maya ventured to the North country where she enjoyed skiing with friends despite her injured shoulder. MRI scans have since confirmed that she has a SLAP tear and torn rotator cuff. Her doctor has suggested an ultrasound-guided steroid injection at the tear to help her manage the discomfort. Unfortunately, such injuries do not heel with time and she will likely require surgery at some point in the future.

On the home front, Kyle and I completed the wiring for his basement renovation. All the lighting and all but 3 outlets worked as expected. It took a while to figure out that the drywallers had covered an outlet box leaving the following section of that circuit disconnected. We excavated the wall, found the box, and completed the installation of an outlet at that location. Presto, all remaining outlets became energized. On a less positive note, we discovered that the flooring installers had done a very poor job of leveling the concrete leaving behind several dips and high spots. With half the flooring already placed, it will be quite a lot more work to now remove it and address the hills and valleys.

We specified 10-foot wide garage doors on the new house so we could be more relaxed while parking than is the case with the 8-foot wide doors at the Road House. In addition to the fun of making the first ingress, I wanted to confirm that doors could be swung open to their full extent without hitting the walls. My car was very happy for the elbow room.

Kyle’s basement renovation project is in the home stretch. Drywalling and floor leveling have been completed. Kyle used contractors for these jobs as neither one of us was too keen on doing it ourselves. Both require specialized tools and benefit from considerable experience. This weekend we will work on installing the recessed ceiling lights, outlets, and switches. We will also get his garage door working again after the drywaller managed to disconnect the electrical circuit which feeds it.

The patterns one can find in ice never cease to amaze me. Talk about the ultimate Rorschach test. If you have a few minutes, click on the image and look around. I think you will be amazed at how many interesting images and shapes you will discover. So far, this winter has been quite mild with daytime temperatures occasionally hitting the mid-forties and often remaining above freezing. Given the amount of mud surrounding the construction site, it is generally advantageous when working on the outside of the house for the ground to be frozen. Naturally, now that work is moving to the inside, when warmer temperatures would be appreciated, the forecast is showing us heading into a cold spell.

One area of the River House that has been very difficult for me to visualize has been the stairs and railings. As of today, our construction foreman single-handedly completed temporary ones to facilitate interior work on the house. Seeing and using them has helped us to finalize design decisions for the final versions. I think they may be one of my most favorite design elements of the house. The photo perspective makes them appear cramped and steep. In reality, they are quite spacious and have a 7-inch rise over 11-inch run, which is widely regarded as the optimal ratio for climbing and descending.

Occasionally, a photo and title tell the whole story. I found my brother like this on our couch this morning talking to Jeanine. I could not resist running for my camera. Marie, his better half, requested a headshot for work. Although I do not have a proper photo studio set up at the moment, I did manage to make an acceptable image, which was not much of a challenge with such a lovely subject.

My brother Mark and his wife Marie arrived late yesterday as did Jeanine returning from her yoga retreat in Mexico. This morning, the kids joined us for brunch before we set out for tours of Kyle’s new house, Formlabs (where Maya works), and finally Maya’s apartment. We returned to Concord for a lovely dinner at Papa Razzi, our go-to restaurant for really good food. It has been quite a while since we spent an entire day with family and it felt really wonderful.

My brother Mark and his wife Marie flew in from Minneapolis this evening to visit for the weekend. I had hoped to do some grocery shopping before their arrival but lost several hours of the day having to deal with a flat tire. I picked up a nail from the River House construction site and finding someone with availability to repair it took much longer than I would have thought. On the positive side, I was able to do my grocery shopping with Mark and Marie which resulted in a far healthier and yummy set of options for dinner. Mark prepared steaks which included searing them on their sides, something I have not witnessed before.

I am happy that our first proper snow of the season did not arrive until all the sheathing work on the River House was completed. Just two more steps before the shell is weather tight. First, we need to install the water and ice shield on the roof and then we need to install the windows and doors. Hopefully, we can complete both of these activities before the end of the month. At that point, we can introduce some provisional heating to improve working conditions for the electrical, plumbing, and HVAC work.

Last night the drilling rig was repositioned for the second bore hole location. The casing for the first bore hole can be seen to the left of the mini-excavator’s left tread. Bedrock was encountered at 141 feet with minimal water. The next steps are to install the geothermal loop tubing into the holes and then fill the holes from the bottom up with grout to ensure proper thermal coupling of the pipes to the ground.

Our geothermal heating and cooling system will require two 300 feet deep boreholes to accept the vertical closed-loop pipes through which water and anti-freeze will circulate to pump heat from the Earth into the house (in winter) or from the house into the Earth (during summer). The first well was completed today. We had 142 feet of clay before hitting bedrock and managed to avoid any aquifers. This is a great result since dense clay and bedrock are both great thermal conductors. With any luck, our second bore hole will be completed tomorrow.

Throughout the design process for the River House, I have been very thoughtful about sight lines both internal and external. Now that the first and second-floor framing is complete, I have been able to walk through the house and visually verify that my calculations were correct. Everything is as it should be and as a bonus, I discovered a sight line that I had not considered. It is possible to look through four different second-story windows to see “through” the house into the patio area and “through” the house again to the other side of the river. You would need a ladder or drone to appreciate this view but I thought it cool nonetheless. So cool in fact, that I decided to fly through the four window openings with my drone while shooting a video. It should be noted that I use my drone almost exclusively for photography and flying through obstacles is not something I have had much experience doing. As I made my approach, I was so focused on setting up the sight line that I managed to run into the house for my first crash in several years. The propellors got trashed but fortunately that was the only damage to the drone. Just before the fateful moment, I did manage to capture the view I was looking for.

Kyle and I spent ten hours today, our longest work session to date, completing the installation of strapping on the ceiling in his basement. Normally, this is a simple matter of cutting the 1×3 straps to length and nailing them perpendicular to the floor joists at each intersection, and then repeating the pattern every 16 inches. We used my cordless nailer to drive the roughly 700 nails required for the 350 or so intersections. In our case, however, we had to shim over 100 of them to compensate for the large variations in joist size/position. This was by far the most labor-intensive and time-consuming part of the job but should result in a nice and flat ceiling.
