Engineering Studies/Audits
A.H. Lundberg is often requested to perform an audit on an existing plant system for a number of purposes including increasing system capacity, system safety, system efficiency, improve stability of ease of operation, trouble shooting and interfacing one system with another or future system. Each audit is tailored to the specific need of the client and may comprise a number of the areas listed above.
Our specialty is the process knowledge of the technology we provide. We utilize this technology to benefit a plant in the review of individual systems including all types of waste gas handling systems, condensate/sour water stripping systems, evaporator systems, and heat transfer systems.
Process Engineering
Process engineering provided by AHL typically includes process flow diagrams, piping and instrument diagrams, customer vessel drawings, pump specifications, instrument specifications, typical general arrangements, assembly drawings (if appropriate) and operating and maintenance manuals. Drawings such as the piping and instrumentation diagrams and instrument specifications can be done on plant title blocks using standard symbolism and specifications.
Operating and maintenance manuals are specifically detailed for the given process and plant requirements. Full information on all supplied equipment is included, in addition to a detailed description of all instrumentation.

Project Engineering
We can provide detailed engineering services for the installation of the project so that installation can be done by the plant using internal personnel or local contractors. We have the capability to do the complete detailed engineering in-house using our own engineers, intimately knowledgeable of the process to be installed.
This includes civil and structural design, mechanical design, electrical and instrumentation engineering, demolition detailing and piping design. We also can provide an erection adviser to oversee the process installation of the system.
Full Project Turnkey
The project can be as small as the replacement or re-tube of a heat exchanger up to a complete evaporation system. All major systems are suitable for installation on a turnkey basis.
AHL will utilize existing plant specifications where applicable and where absent, we generate new specifications for plant approval. Further, the project will utilize plant preferred equipment and suppliers as well as utilizing local vendors that provide support to the plant.
We have the capability to perform all of the major engineering disciplines in-house including process engineering, mechanical design, structural design, electrical engineering and piping design.
