Pipe and Plumbing
At our commercial HVAC company, our team specializes in providing high-quality pipe and plumbing mechanical construction services. From engineering and design to seamless commercial HVAC installation, we ensure reliable and efficient plumbing solutions for commercial projects. Our pipe and plumbing capabilities include numerous applications.
HVAC Piping
At P1 Construction, LLC, our commercial HVAC contractors specialize in the design and commercial HVAC installation of HVAC piping systems. Our mechanical contractors ensure that all piping components are properly configured and function efficiently to support heating, ventilation, and air conditioning systems, improving comfort and energy efficiency.
Industrial Process Piping
To ensure safe, reliable, and efficient transport of fluids in manufacturing and processing environments, we provide custom industrial process piping solutions for a variety of industries. Our expertise includes the design and installation of piping systems that meet strict industry standards and operational requirements.
High Purity Piping
With a focus on industries that require the highest standards of cleanliness, our mechanical contractors offer high purity piping for applications like pharmaceuticals, biotechnology, and food production. Our piping experts design these specialized systems to prevent contamination and maintain the integrity of sensitive processes by using specialized materials and precise installation techniques.
Polypropylene Piping
At P1 Construction, LLC, our mechanical contractors have experience in installing polypropylene piping, a highly durable, chemical-resistant solution that is ideal for various industrial and commercial applications. Polypropylene piping is particularly well-suited for environments where corrosion resistance is essential, providing long-lasting performance in challenging conditions.
Storm Drainage Systems
To manage runoff and prevent flooding, we design and install storm drainage systems tailored to each project’s needs. These systems help direct water flow away from your property, protecting infrastructure and the surrounding environment from water damage.
Medical Gas Systems
Our mechanical construction company provides specialized medical gas systems for healthcare, pharmaceutical, and laboratory facilities, ensuring the safe and compliant installation of gas piping systems that support medical procedures. Our services include the installation of oxygen, nitrogen, and other critical gases required in hospitals and medical centers.
Chemical Waste Systems
At P1 Construction, LLC, we construct chemical waste systems that provide safe and efficient solutions for managing hazardous chemical waste. Our mechanical contractors make sure that all systems comply with environmental regulations and are designed to handle the safe transport and disposal of chemical waste in a controlled, sustainable manner.
Backflow Installation and Testing
Our mechanical contractors specialize in backflow installation and testing, providing services to warrant the safety of water supplies by preventing contamination. We install backflow prevention devices and conduct testing to ensure that drinking water systems remain safe and uncontaminated.
DWV (Drain, Waste and Vent) Assessments
To evaluate the health and performance of your plumbing system, we offer thorough DWV (Drain, Waste, and Vent) assessments. With our DMV assessments, we’ll identify potential issues like blockages or inefficiencies in the drain, waste, and vent systems, helping to prevent costly repairs and ensuring proper system function.
Piping Assessments
With our piping assessments services, our commercial HVAC contractors provide comprehensive inspections of piping systems to detect leaks, wear, and any issues that may compromise performance. We offer detailed reports and recommendations to improve system efficiency and extend the lifespan of your infrastructure.
Mapping
To manage runoff and prevent flooding, we design and install storm drainage systems tailored to each project’s needs. These systems help direct water flow away from your property, protecting infrastructure and the surrounding environment from water damage.
Trenchless Pipe Services
Trenchless piping repair and replacement methods have become popular because they are cost-effective, durable, and cause minimal property damage. The trenchless method can be performed on any type of piping, including sewer, drainage piping, pressure piping, chilled water, hot water, domestic water, and even electrical conduit.
Utilizing fewer excavations, our mechanical contractors can perform the rehab or replacement of underground piping from within.
Trenchless pipe repair is a great alternative since most work does not require your facility to shut down operations or require large flooring, wall, and other repair bills like traditional trenching can.
Sheet Metal
In addition to our pipe and plumbing capabilities, our mechanical contractors deliver top-tier sheet metal mechanical construction services. Our sheet metal construction capabilities include the following:
Ductwork (Supply, Return, and Exhaust Air Systems)
At P1 Construction, LLC, we specialize in the installation of ductwork for supply, return, and exhaust air systems. With this service, we ensure efficient airflow and ventilation, tailored to the specific needs of your commercial or industrial space.
Variety Of Alloys (Stainless Steel, Aluminum, Hastelloy)
Our mechanical contractors have experience working with a variety of alloys (including stainless steel, aluminum, and Hastelloy), to ensure strength, corrosion resistance, and durability for your project’s unique requirements.
Dust Collection Systems
At P1 Construction, LLC, we design and install customized dust collection systems to improve air quality and reduce maintenance. Our dust collection systems guarantee compliance with predefined safety regulations and create a cleaner, safer work environment.
