Changing the Boston Skyline
On Tuesday, August 7, 2018, the One Dalton Tower project officially topped off!
As the last tower of its height to be built in the city for a while, One Dalton by Four Seasons is changing the Boston skyline and that’s a special thing to be a part of. Standing at 61 stories tall, this will be the tallest residential tower in New England. Working with Tishman Construction / AECOM, Suffolk Construction, and the 1D project team has been an extremely fulfilling experience for us, and our team has gained a lot of knowledge along the way.
Fenagh provided third party special inspections and material testing for the owner, and after a lot of hard work, we’re happy to see our scope of work near completion.
The MOE of a material is a number that is defined by the ratio of applied stress to corresponding strain within the elastic limit. Physically, it indicates a material’s resistance to being deformed when stress is applied to it. MOE also indicates the stiffness of a material, with the value of elastic modulus being higher for stiffer materials.
MOE testing of the concrete was in heavy demand throughout the duration of the project because it was used on both the core wall and the columns. The MOE data was crucial to the project so it was vital to have everything thoroughly executed in a timely manner.
Fenagh’s Engineering Manager, Robert Munck, was a key player from our team and he definitely saw the silver lining in these challenges. In fact, he says his favorite part of the project was the fact that these challenges, “made the Fenagh team stronger and better suited for the next big project of the same scope.”
Scope of Work
The Fenagh project team performed reinforcing steel, concrete, welding, coring, sika FRP, and off site structural steel inspections. Fenagh’s scope of work was so large on One Dalton that it required a resident multidiscipline inspector, concrete inspector, and project coordinator on site daily to keep up with the demands of the project. There were a multitude of services provided each day varying between the following inspections:- Concrete field / laboratory testing
- Reinforcing steel installation / monitoring
- Inspection coordination services
- Welding / bolting inspection shop and field
- Masonry inspection and testing
- Fireproofing inspection and testing
- Concrete trial batch testing
- Modulus of elasticity of concrete testing
- Temperature monitoring via thermocouples
- Concrete coring monitoring
- Concrete segregation testing
- Glass reinforced fiber installation monitoring for concrete repair / strengthening
Project Challenges
As you can see, Fenagh was involved in many different aspects of One Dalton’s construction, so it is no surprise that our team faced a few challenges along the way. For example, the belt truss was an extremely complex design that required an immense amount of onsite welding. We began with one inspector, then brought on another because the demand for inspecting the weld kept increasing. It was essentially a race against time because the project schedule hit a halt until the belt truss was fully erected and encased in concrete. We increased our pace of work to meet these demands, and even pooled resources from our West Coast office. It was a very busy time and we made sure to work efficiently to deliver on the client’s needs. After close to 3 months, the belt truss was finally completed and the construction of the condos began again.
