Swimming pool construction project
In 2017 I embarked on a project to design and build a complete swimming pool from scratch without using any contractors. As with all construction projects, delays ensued and what I originally envisaged to be a three-month project took more than six months to complete (or twelve including breaks for winter, travel etc.).
Below are a series of articles in chronological order documenting the very laborious, but always interesting process.
Testing the limits of online self-education
So I’m building a pool. More precisely, I’m building a pool, a deck, supporting retaining walls, storage cupboards, privacy shield, garden beds, and lighting,
Detailed design
Fiberglass pool or concrete pool? Concrete pools are built directly in the ground onsite. Concrete (or more often shotcrete) is set on a framework of steel reinforcement and then plastered or tiled.
Choosing a pool shell
Fiberglass pool shells come in a variety of shapes and sizes, but are broadly similar in their construction. They generally consist of a number of layers of fiberglass and other materials and a final “gelcoat” finishing layer that is the finished surface of the pool.
The autodidacts' era
It struck me recently that this endeavor would not have been remotely possible pre-Internet, or even pre-YouTube. The ability to track down tutorials, instructional videos, and professional forum discussions on topics as diverse as structural engineering to how to stop a wedding (I kid you not).
Documenting the process
Installing a Mobius ActionCam to take periodic photographs of the site. We will assembled the stills into a time lapse video at the completion of the pool construction project.
Demolition
Before we can begin building the pool, a certain amount of destruction is required. Specifically, we need to:
Demolish the red brick paving above the pool area.
Excavation preparations
Alrighty, it’s excavation time. To prepare for the dig I made the dig plan below:
Dig plan showing the elevation of each area to be excavated
Digging time!
I’ve just completed two full days excavating and the site is taking shape.
1.7 tonne excavator
Removing the existing vegetation prior to full excavation.
Excavation (mostly) complete!
Mostly. There is still plenty of shovel work remaining to get the footing trenches exact, and there’s a substantial amount of manual digging to do in the areas pipes were discovered during the dig, but the rough (read machine) excavation is complete.
Collapse!
It was always likely that the unpropped excavated wall at the rear of the pool deck would collapse if it got significantly wet.
Finalizing the excavation
With several backbreaking days of pick and shovel work behind me, I think I can finally call the excavation complete. Things went mostly according to plan, with the exception of a possible miscalculation of the pool wall to wall width…
Building the time lapse video
Before embarking on this construction project, I setup a camera to take a single photo every 10 minutes during the entire process.
