Diversified Inspection Solutions team of inspectors will provide the most experienced inspectors to ensure client assets, capital projects are in compliance with codes, site specific quality plans, Federal and state regualtions. This Involves checking something, i.e., examining and assessing something. In the world of construction, inspection is the critical appraisal of materials, items, or systems involving examination, testing, and gauging. Inspectors take measurements and make comparisons.
All our weld inspections will be inspected by a Certified Welding Inspector (CWI) certified through the American Welding Society (AWS). Each AWS CWI will be up to date with certification requirements and visual acuity requirements per AWS QC-1. Below are the specialized welding codes our inspectors will be following.

Over the last several years field construction has been minimized to eliminate excessive cost on project sites while fabrication shops are now fabricating more and more of the mechanical equipment and shipping in complete packages to be assembled, bolted and installed on project sites. Our inspectors will perform the following task to assure field rework is eliminated during construction.
- Piping and Instrument Diagrams (P&ID’s) Walk Downs – Each Piping and Instrument diagram will be verified for compliance and operational success for startup and full operational efficiency.
- Factory Acceptance Test – FAT’s will be witnessed and detailed reports to show functionality of each piece of equipment.
- Run Test – These tests will be performed and witnessed to ensure client requirements are met with satisfactory results.
- Process Flow and Valve Orientation – Inspections to verify valves, piping and directional flow of components will be spot on for no downtime during start up and commissioning.
- Torqueing – Bolting of equipment is crucial to the success of plant start up and operation. Bolting and Gasket materials are verified by inspectors to ensure the safety of all personnel. This can’t be achieved without the witnessing of activities during turn of the nut installation task.
- Lock Out/Tag Out – One of the most important safety practices in the industry to help prevent mishaps in the construction workplace. Valves being put into operations now and in the future rely on lock out/tag out procedures to prevent energized failures.
- NACE Coatings – The National Association of Coating Engineers (NACE) was established to protect people, assets and the environment from the adverse effects of corrosion. Our job is to ensure the safety of our clients and field personnel are protected from any unexpected surprises.
Diversified Inspection Solutions will verify contractors and fabrication shops follow installation procedures for structural integrity of projects. These inspections consist of detailed inspection activities throughout the building process.
- Erection Connections – Steel members being assembled to complete a structure soundness inspection to ensure the structural integrity of any building.
- Detailing – Poor welding or misalignment of steel components can adversely affect the structural performance or safety of a building. This is important for all buildings, but especially for critical structures such as hospitals and schools that must be able to withstand seismic events.
- Anchor Bolting – Typical inspection procedures consist of reviewing the type of anchors that will be installed prior to the commencement of work and determination of what aspects of the installation are critical from an inspection standpoint. This varies from anchor type to anchor type. Generally, inspection focuses on verification that the anchor is in accordance with the project specifications, that the installation procedure is in accordance with the MPII, and that the anchor size, placement and embedment are in accordance with the contract documents.
- Bolted Connections – Bolted connection is more frequently used than other connection methods. This is in particular due to the development of higher strength bolts, the easy to use and strong structural steel connections become possible. In the bolt design, two kinds of forces including tension and shear forces should be considered. Verification of bolting has become an important inspection point during fabrication and construction.
- Handrails – The Occupational Safety and Health Administration (OSHA) guidelines are to be followed when inspecting hand rails. These requirements have to be met in order to be recognized as safe for everyday use. Height requirements and load requirements have to be verified for compliance.
- Metal Decking and Grating – These are just as important as handrails as they are another step in the construction process to be verified installed safely according to OSHA.
In order to operate, commission a project safely and efficiently E&I inspectors will provide oversight and surveillance on equipment to achieve maximum success on turnover operations. The Electrical Inspector must verify that all electrical equipment located in the classified areas meet the requirements of the NEC for use in that particular hazardous location.
These inspections will include various activities such as:
- Grounding – Electrical grounding is a backup pathway that provides an alternating route for the current to flow back to the ground if there is a fault in the wiring system. It facilitates a physical connection between the ground and the electrical equipment.
- Functional Test – is critical to the performance of any complex system, as it checks the system against its design documents and specifications to ensure that it performs all of its functions as it should.
- Point to Point – Proper Point-To-Point (PTP) testing verifies readings from sensors in the field all the way back to the operator’s station and confirms correct mapping of points on the Graphical User Interface (GUI). An accurate record of all testing must be maintained and deficiencies noted and retested once they have been rectified.
- Loop Checks – is the final process before the commissioning of the processing system. Loop checking is the process that confirms the components wired correctly and also helps to ensure that the system is functioning as designed. The loop checking checks the connection between each component in the control loop.
Rotating Equipment can become an owners worst nightmare when rotating equipment is not properly maintained and installed correctly. When installing rotating equipment steps that need to be followed can prevent the excessive wear and tear on a piece of machinery. Properly installed rotating equipment can last 25 to 30 years if the proper steps are taken to ensure the accuracy of installed equipment. These steps can keep operations running for long periods of time and be cost effective when done correctly.
- Sole Plate – are base plates grouted into a concrete foundation. And these plates provide vibration support and leveling support for a machine, such as a pump or a compressor. So depending upon the design engineering, there are usually bolt holes or pre-installed anchor bolts required to secure the feet of the machine to the machined plate. Oftentimes, leveling pads or steel footings or shims are required to adjust to a flat, level surface during installation.
- Pre Alignment – Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability. For appropriate applications, the time, expertise and instruments needed to achieve precision alignment (tolerances of less than 0.005 in) will prevent seal leakage and extend bearing life.
- Post Alignment – Up to 50% of damage to rotating machinery is directly related to misalignment. Machine vibration, bearing damage, premature seal wear, and coupling damage are all examples of issues pumps experience if improperly aligned at installation. Misaligned pumps can also draw up to 15% more energy than aligned pumps. Ensuring these steps are followed is crucial to the lifespan of any equipment.
- Shaft Alignment – Initial alignments and hot alignments (Final) are performed to prevent excessive stress on rotating equipment and ensure operational safety for plant processes.
- Piping Alignment – Undue stress to equipment from improper piping installations can cause catastrophic failures to any piece of equipment. We verify alignment activities are compliant to eliminate these failures from occurring.
Our coatings inspectors focus exclusively on ensuring that all pipe produced meets client requirements and conforms to accepted standards (usually API 5L). Field inspections will be performed to assure correct preparations by blasting and other means while final inspections of mill thickness and correct applications where applied per specifications and governing regulations. All inspections follow the guidelines of the National Association of Corrosion Engineers (NACE) and the Society for Protective Coatings (SSPC). The NACE inspector, or quality assurance (QA) inspector, works directly for the asset owner, or general contractor, and corroborates the findings and measurements of the painting application company. This position acts as a vital check to ensure that no corners were cut and that all aspects of the project were followed to spec. Not only should this help extend the life of the asset, it should also help prevent the expensive and potentially dangerous consequences from a premature coatings failure. Types of coating inspections:
- Surface preparation – SP1 through SP16
- Coating application – Functional coatings may be applied to change the surface properties of the substrate, such as adhesion, wettability, corrosion resistance, or wear resistance.
- Adhesion – In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied.
- Mil thickness – In the U.S. the thickness of paint is expressed in mils (one mil equals 1/1000 of inch).
Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly and that it is operated and maintained properly. MI is 1 of the 14 elements included in the OSHA Process Safety Management standard. MI includes equipment/assets such as pressure vessels, storage tanks, piping systems, and associated hardware (valves, fittings, etc.), relief devices, and emergency shutdown/control systems. MI encompasses the activities necessary to ensure that equipment/assets are designed, fabricated, installed, operated and maintained in a way that provides the desired performance in a safe, environmentally protected, and reliable fashion.
