Pipe Rack and Pipe Modules - 2015

We had to fabricate all the steel to make a pipe bridge then load it on trucks to ship to the galvanizer and then to a fire proofer. Once all the members were fire proofed, the steel was brought back to us and assembled inside our fabrication shop in predetermined lengths.

The sections of the bridge were approximately 14’-8” square and ranged from 45’ long to 76’ long.
They were moved out of our shop on skates and loaded on trailers using a 55 ton crane and a 120 ton crane. The trailer would then take them to a location in our yard where they were then unloaded for pipefitters to install piping where it was required and for a fire proofing crew to fill in the block out sections that were required for assembly. After all processes were complete and went through QC they were loaded on trailers and shipped to the job site.

Lee Mechanical was contracted as the General Contractors for this NSHAP Upgrade. This contract, which includes the installation and erection of a KHD designed PyroProcessing System, which will increase the line's production rate to 2400t/day and be compliant with the new NESHAP environmental regulations.

The project incorporates constructing a five-stage single-string Preheater tower over the existing kiln, while the kiln is in operation. Modify the existing six-pier rotary kiln to a two-pier kiln and add a new clinker cooler. The existing kiln will be cut to achieve a final length of 51m, transforming the existing long dry kiln system into a new, modern, energy efficient, fuel efficient, and environmentally friendly PyroProcessing system. The new system was equipped with a new whole tire handling system and will be capable of co-processing up to approximately 7% of whole tires as an alternative fuel.

Lee Mechanical was also over the erection of a new dry lime injection system. To reduce NOx emissions, as well as a modification of the existing SNCR system. New dust collectors were installed to meet stringent particulate emissions requirements.
We incorporated a new raw material grinding VRM system, coal dosing systems, as well as erection of structural steel.

Plant Upgrade – 2015:
The debottlenecking in 2015 was a complete addition to a process plant and consisted of installation of structural steel building with metal siding and concrete floors, installation of several vessels and pumps, fabrication and installation of small and large bore piping, installation of HVAC and fireproofing systems, installation of all associated piping and tie-in connection to the existing system. This project was done in a hazardous area that required constant communication and coordination between Lee Mechanical, the customer, and all subcontractors. Lee Mechanical acted as General Contractor on this project. The project was done in a timely manner, within budget constraints, and without any accidents.

Install Package Boilers – 2015:
This project was the second and main phase for the installation of two package boilers and new boiler house building. Lee Mechanical installed all associated piping, stacks, fans, and did all code work related to the boilers. Lee Mechanical set, aligned, and assisted in startup of all the pumps and equipment. Lee Mechanical set pipe racks, structural steel platforms, walkways, and stairs. Lee Mechanical also stepped up and did the sprinkler work after the previous contractor was removed from site.

HVAC Install – 2015:
This project was to install the HVAC portion of the Warehouse addition. The scope included fabrication and install of duct work, procurement of materials, and managed subcontractors for controls and testing & balancing on the system.

Safety Project – 2014:
The a recently new site of this chemical company had a project to upgrade the ventilation and exhaust system to bring the site up to the company's standards. Lee Mechanical was contracted on this project and a few others that came after it on the site. This project consisted of:

• Fabrication and install of three large steel platforms.
• Install of two large air handling units and two large exhaust fans.
• Purchase and install of new unit heaters, gas piping, and ductwork.
• Demo several existing pieces of equipment & ductwork.
• Purchase and install of new drain pipes and plumbing.
• Purchase and install of new copper piping.
• Install multiple safety showers and eyewash stations.
• Insulate most of the piping.
• Install new SS exhaust piping in 3 areas.
• Purchase and install of several exhaust hoses with associated duct.
• Install of 5 laboratory hood stations with associated duct.
• Install of all new duct from new units and fans to existing duct.
• Install of smaller baghouse and associated duct.
• Purchase and install of controls.
• Testing and balancing for system.

Overall, the project did have some lag time on the owner supplied materials, but we worked with the schedule and made this project as smoothly as we could. The project was stretched out due to late delivery of owner supplied materials and the civil contractor that was removed from site (not contracted by Lee Mechanical), but overall Lee Mechanical installed in a timely and effective manner.

Platter Plumbing Replacement -2015:
The work on the platter plumbing and equipment replaced during normal operations of the plant required very close communications between the plant managers and Lee Mechanical supervision and electrical contractors in order to keep production running at normal capacity with tie-in work being performed over weekends. The work consisted of stainless steel and carbon steel pipe welding along with Kynor, CPVC and PVC piping. Replacement of pumps, specialty equipment, vessels and steel work was also a large portion of the work required to complete the project. The work was completed in a tight schedule and within budget.

Press Mold Renovation-2015:
The existing molding department equipment, mechanical services, and concrete was demolished out and replaced in a relocated area with all new updated equipment and plumbing services. The existing floor was removed and reinforced to withstand the new equipment weights and new overhead crane system. The plumbing for the new system was replaced with stainless steel, carbon and PVC piping with the plumbing for each machine ran underground and up through pipe risers. The project was within budget and completed in a timely manner.
