A girder is a support beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web, but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges.
A Chinese construction contractor CHEC has been constructing a new bridge over the Rio Minho River as a part of the May Pen to Williamsfield Toll Road Development Project. Work started in January 2021. I go past the site on foot once a week as a part of my exercise routine and have been taking photos of the works since February 2021. Some are highlighted in my post Mystery of the Secret Death and Burial of the Original Foundations. https://pattyandcocobread.wordpress.com/2021/12/25/cover-up-on-the-west-bank/
Today I was able to see a girder being placed and took photographs. The process is quite interesting. I am not an engineer and could only interpret what I saw through layman eyes. The first photo is from earlier and shows the span of the river and the number of girders required. The unit placed today was in the section numbered 4.
The operation appeared to be slow, but the girder was connected, moved and placed in 34 minutes.
