Engineering and Construction Case Study Examples

• H+M took a pre-designed front-end loading (FEL) package to EPC execution.
• Full EPC project provided end-to-end solutions, from engineering design and procurement to construction and project management.
• The project included installing equipment, piping, instrumentation, electrical systems, structural components, civil work, temporary facilities, engineering services, and construction

• H+M Industrial EPC construction-only project consisted of the replacement of an oxygen piping system and vaporizer.
• The field installation scope consisted of civil, structural, equipment, piping, and electrical disciplines, including pre-outage and outage work.
• Additional scope details included excavation and installation of new foundations, including a prefabricated concrete foundation to support the new vaporizer burner, structural supports and platforms, stainless steel pipes for oxygen service, and electrical demolition.

• Full EPC package included detailed engineering designs for the entire system, including equipment sizing, piping layout, instrumentation and control systems, and electrical design.
• During construction, H+M managed various disciplines, including civil, structural, mechanical, and electrical.
• Other deliverables included procurement of equipment/materials.

• H+M Industrial EPC was responsible for the project management, supervision, shop and field labor, fabrication, supply and operation of equipment, safety management, transportation, subcontract management, and other goods and services required for the underground piping construction project. 
• The construction phase included excavation, shoring, bedding, coating, installation, hydro testing, and backfill of several piping systems.

• The EPC package included detailed designs for piping/mechanical, civil/structural, and E&I construction. 
• Other deliverables included 3D modeling, fabrication, and procurement of equipment/materials.

• EPC package included detailed designs for civil, mechanical, structural, piping, layouts, wiring, and electrical. 
• Other deliverables included 3D modeling, fabrication, procurement of equipment/materials, piping/mechanical, civil/structural, and E&I construction.

We were engaged to execute a full turnkey EPC project for a new chemical production facility. The project spanned every phase, from conceptual engineering to construction, requiring seamless collaboration across all disciplines

• Full engineering, procurement, and construction package from FEL 1 through start-up
• Scope included five ship/barge loading docks
• Detailed design and construction of interconnections for three Enerflex skid units with dock loading arms
• All piping produced was 100% fabricated and tested at H+M’s on-site fabrication shop

‍

The project scope included:

• Installing vault pipes in four different manifold vaults and piping installation to tie-in the vaults. 
• Installing three horizontal pumps and three vertical pumps, aboveground tie-in pipe to the ship dock pipe rack, and underground pipe from the main vault to the pumps.   
• +450 bolt ups, including several Twin Seal valves, 9,200LF of aboveground pipe, and +2,000LF of underground pipe. 

As part of a large-scale midstream terminal project, we completed the mechanical installation of manifold and dock pump systems for a Gulf Coast facility. This EPC mechanical scope required detailed coordination across multiple disciplines to meet the client’s schedule and performance expectations. The work involved complex piping tie-ins, pump installations, and integration with ship dock infrastructure, all executed with a focus on safety, precision, and speed.

• New vapor return system and Thermal Oxidizer
• Retrofit and addition of existing plant infrastructure
• Tight timeline to meet Environmental Compliance date
• Commissioning Support was provided to ensure Thermal Oxidizer was successfully FAT tested

A major terminal operator turned to us to install a thermal oxidizer system aimed at controlling volatile organic compound (VOC) emissions. The project required a retrofit of existing infrastructure to meet new environmental compliance mandates.

• Incorporated new firewater piping tie-ins to existing loops
• Completed deep excavations and shoring systems
• Assisted in commissioning support with client

• Simulated client’s process inputs for the project 
• Consulted with tower internals company to size packing and liquid/vapor distribution
• Completed 100% of the fabrication work for the project at the H+M shop

We were selected to design and fabricate a custom scrubber system for a Texas-based chemical facility. With tight scheduling and process-specific requirements, the project demanded precision, speed, and deep technical knowledge of chemical scrubbing systems.

• Scope included vault piping installation in 4 separate manifold vaults and installation of piping to tie in the vaults
• Installation of 3 vertical pumps and 3 horizontal pumps, underground pipe from main vault to the pumps, and above ground tie-in pipe to the ship dock pipe rack
• +450 bolt ups, including many Twin Seal valves, +2,000LF of underground pipe, and 9,200LF of above ground pipe
