Advanced Candu Reactor (ACR-1,000) Multi-Discipline Module
The term "Module" can be defined as an assembly comprised of structural steel, pipe supports, process piping & equipment, instrumentation, cable trays, panels, embedments, rebar, etc. within a defined volume. Models can be prefabricated either off-site or at an on-site fabrication facility and installed in the field. Constructing with the module concept allows fabrication of many modules to take place as parallel activities, shortening the overall construction schedule while fabricating in a controlled environment.
This particular example represents a Prefabricated Permanent Formwork (PPF) Multi-Discipline Module. Which translates to a module consisting of process piping & equipment, steel wall plates, embedments, temporary steel, rebar, etc. The plate work that makes up the walls act as the formwork and remains in place after the concrete has cured.

O'Neal Quarry
This project is a material handling and processing facility modeled in Tekla Structures Version 12.1. The project consisted of the primary crusher structure, conveyor towers, and transfer towers interacting with existing conveyor lines for transferring raw ore.
The project contained 701.5 tons of steel; 15,131 parts in 1,276 assemblies with a total of 1,783 drawings. The main structure was supplied in 18 large assemblies, some with over 350 individual parts, which required between 4-6 shop assembly drawings each, shipped from the shop to facilitate quick erection. The main dump hopper was shipped in (9) 10'x10'x15' cubes assemblies and sat upon (4) 40' tall tower assemblies. Each assembly averaged between 18,000 & 20,000 pounds each. There are three smaller screening/transfer towers further up the hill which were supplied as beam and column assemblies. In addition there were 29 towers for supporting the conveyor system between the towers. Some of these towers were too tall, or too wide, to ship in one piece and so were supplied in two parts with field splices.
This project was interesting as the contractor and the owner wanted to keep field erection time to a minimum so the towers and the dump hopper were shop assembled in as large of pieces as could be shipped. Typically 10'x10' square and between 15' & 40' long.

Rio Tinto Head Frame (Shaft #10) for Resolution Copper Underground Exploration
Although this project weighed in at a mere 614 tons...it involved very complex geometric construction of the plated box columns and beams. In addition to the trapezoidal construction of these box members they were also laced throughout with internal plate stiffeners.
Due to the precise requirements in elevation of the sheave hoist equipment…milling of the various plate and wide flange members that made up the support stool structures was required. The stool structures themselves were fabricated in one shop and shipped for milling to another. This required calculated interaction of the various pieces that made up these support stools do to the fact that the modeling could not directly reflect the milled plate thicknesses. Special considerations were also required due to the fact that the erector on the project had requested shop assemblage of the leg structures and the cage framing to as much of an extent as possible.
Detailing of this job was done using Tekla version 13.1 and produced 33 GA, 575 Assembly, 1132 working drawings.

Flex Power Plant
This model was done for
Mountain States Steel in Utah for NEM out of the Netherlands. This was a duel dimensioned project within Tekla, imperial and metric dimensioning.
The tonnage on the project was 2 plants with each tonnage coming in at 1350 tons per 2,700 tons total. It included moment and braced frames, horizontal bracing, tank (plate) work, ladders, cage ladders, gates, handrails, and stairs in addition to the regular structural scope. This project had every possible type of construction and was dual dimensional.

Chesterfield 3,4,&5 FGD
Detailing of the ductwork for the Chesterfield Flue Gas Desulphurization system proved to be a project of large scale and unique challenges that demonstrated the power and flexibility of Tekla Structures software. The scope of detailing for this system consisted of two ducts from boilers to the inlets of ID fans and discharge ducts from the ID fans to a common duct that gathered the flow into the scrubber inlet duct. the ducts ranged in size from approximately 10 square feet up to 20' x 40' and ran over 1,000 linear feet. The ductwork consisted of 50 duct assemblies with a total of 10, 879 pieces and 806 tons of steel. Unique features that were incorporated into the model included access doors and instrumentation ports, guide and slide base assemblies to account for thermal expansion at elevated temperatures, and internal pipe braces and turning vanes. Tekla Structures was a valuable tool in modeling the vast amount of flat plate and structural steel, as well as the unconventional features of the ductwork in a timely fashion.
