BLOG 14 - AESS CUSTOM CATEGORY

 

AESS CUSTOM CATEGORY

AESS Custom category  allows flexibility in the design of steel.

It also requires a high level of communication.

The premium ranges from 20% to 250% over regular steel.

These type of custom elements was created so that there’s an allowance of a custom selection for the attributes or characteristics that are used to define other categories.

Reused steel is also included for sustainable purposes.

EXAMPLE 1 : HEATHROW TERMINAL 5

Located in London’s main airport.

Architect’s: Richard Rogers Partnership, Pascall + Watson.

Engineers: Arup and Mott MacDonald.

Construction and integration of 18,000t complex plan spanning roof seemed to be the challenge.

The massive steel arches, weighed a combined  2,100t and were bolted into position.

This project in England has made use of a range of AESS category types.

The connections are made using a combination of custom work for the central hinge, and showcase level of fabrication and finish for the legs/ column supports.






EXAMPLE 2: ANGUS TECHNOPOLE, MONTREAL

Located in Montreal, was originally a locomotive shop and now used as offices and commercial space. It is an excellent example of a green renovation project.

Most of the materials have been reused and received a very high marking in material reuse.

 


Minimal cleaning and no repainting to preserve the original look of the building.

A custom specification is required in order to make it fit into the aesthetics of the old building.

 

EXAMPLE 3: WELLS FARGO PEDESTRIAN BRIDGE

Located in Salt Lake City, Utah.

Seamless curved structures.

Bending steel is a very particular process that has its own technical requirements to ensure that the surfaces do not warp or buckle.

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

BLOG-16 FABRICATION, ERECTION AND HYBRID STRUCTURES

Image
  FABRICATION: The process of  steel fabrication  involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. ERECTION LIFTING, POSITIONING AND PLACING OF STEEL MEMBERS IN A STRUCTURE  Once the member(s) are lifted and placed in the required place, with the help of temporary supports and equipment, they are fastened and fixed, depending on the nature of connection.  Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. HYBRID STRUCTURES Hybrid structures are structures built with composite materials a combination of different materials with steel. A common  hybrid system  consists of hollow core slabs together with steel or cast-in-situ concrete frames                       EXAMPLE STEEL WITH TIMBER     I...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon. Definition ALLOY :      A homogeneous mixture of a metal with other types of elements                       ...
