As I try to better understand construction timelines and processes in Chicago, I’m going to keep track of this project that annoyed people cycling for six months.
Project: Underground utility construction [not sure what kind]
Location: Milwaukee Avenue between Ashland and Paulina
February 2011 – Construction project begins (I’m not certain it started in February, but I took my first photo of the project this month).
Sometime here the construction project ends and the surface is replaced with rough concrete. Two points to make here: The construction crew could have floated the concrete more to make it smoother; the concrete only needs a week to cure, and can then be removed and replaced with asphalt.
July 25, 2011 – Rough concrete is replaced with asphalt.
August 2011 – Center and parking lines are striped.
August 13, 2011 – Bicycle shared-lane markings still don’t exist.
September 21, 2011 – Bicycle shared-lane markings added, but incorrectly: they’re too close to the parking stripe.
Someone riding a bike rolls in and out of construction zone barriers, presumably to avoid the car traffic and the little room between the cars and barriers.
A Chicagoan riding her bike in the construction zone waits for the light at Ashland Avenue to turn green.
What is floating concrete?
Draft: Floating concrete, or to float the concrete, means to drag flat objects over the concrete to push aggregate downwards and bring liquid upwards. The more times this is done, depending on the float tools, the concrete surface will become smoother. A concrete floor in a restaurant has been “finely floated” to create a smooth, shiny finish.
Sidewalks are floated more than road surfaces. After a sidewalk is floated, it is often brushed to create a texture.
