MEPF contractors need the capability to analyze intricate building systems and to manage construction workflows cost-effectively so they can deliver quality customer service. They want to minimize project costs, complete tasks faster, meet construction standards and local building codes, and optimize all construction materials and resources. Today, contractors can barely achieve their BIM objectives without accurate onsite and offsite prefabrication information. This is why MEPF shop drawings are a top priority for architects, engineers, and fabricators involved in building construction. Layout drawings give multi-dimensional views based on predefined user rules, and they include annotations, schedules, and other details needed to construct, analyses, lift, move, and put up a range of mechanical elements.
Spool drawings serve as a guide for the development of plumbing lines, from concept to the ultimate piping system setup. These technical diagrams meet prefabrication standards and the contractor’s specifications. For instance, detailed and accurate HVAC drawings help onsite personnel, such as plumbers and pipefitters, to understand all pipework and its interactions with other building systems and components. Plumbing shop diagrams also depict the physical assemblage of equipment and the spatial relationships between systems.
Electrical shop drawings are essential to the accurate fabrication of electric components and systems within a building. These drawings include details such as network loops, user-defined dimensions and ratings, component location relative to adjacent grid lines, and material schedules. Overall, the diagrams depict power, lighting, surveillance, and communication systems. Typical drawings include:
A contractor responsible for the design and installation of a fire detection and notification system needs to use shop drawings to get their project right each time. Typical fire alarm blueprints must meet requirements of the state, including being drawn to a specified scale. The models should show details such as the type and make of all equipment, number and type of circuits, zoning information, and wire types and sizes for every circuit. Other essential specifications include:
A proper electrical installation depends on shop drawings that use the correct electrical symbols, line colors, and component tagging procedures which are crucial to producing quality electrical schematic drawings. Additionally, these tasks should be completed by drafters who understand the importance of accurate shop drawings for the sake of life, limb, and property, and according to National Electrical Codes (NEC).
Intelligent electrical shop drawings can be produced for control systems that automate the task of generating wiring lists for control panel builder and the creation of wire number labels, component tagging, and electrical load analysis. We can supply electrical schematics with wiring and component information which can be downloaded into spreadsheets for further use.
Whether your architectural project is large or small, or the deadlines may be extremely tight, we can help your firm accomplish the task of producing the many shop drawings for structures, including:
Our team of drafters is flexible and can adjust quickly to peak demands for engineering changes in time for upcoming client reviews. Contact us to discuss how quality electrical shop drawings can relieve your engineers and designers to concentrate on more important duties.
Accurate dimensional clearances for MEP systems are maintained when shop drawings are coordinated using final equipment, ductwork and auxiliary systems locations and footprints. Multiple sub contractors are usually employed when installing mechanical, electrical and plumbing systems, and lack of knowledge of mutual space requirements are common. Inter-disciplinary coordination using shop drawings will show relevant plane transitions for precise floor space and wall and floor penetrations.
Shop drawing coordination will reduce the need for field verification of dimensions. Major mechanical room equipment is installed by a mechanical contractor. Yet, the installation of a commercial chiller, for example, also requires structural clearances, temporary openings, construction rigging, electrical connections, insulation, plumbing and final commissioning. Coordination shop drawings that show multi-discipline background information will ensure accurate and efficient equipment installations that require multiple trade interfaces.
Engineering specification information found in shop drawings is useful for final engineering comparison and approval per original design specifications. Detailed performance and utilization data not listed in general vendor documentation can only be found in detailed shop drawings. Final coordination of mechanical schedules and material specifications can then be performed using the manufacturer’s data sheets and shop drawing information.
Often, the project scope of deliverables will include the manufacturer’s product or material data sheets (cut sheets) to be attached as part of the final documentation. Establishing a partnership with an out-sourced firm to curate and coordinate the vast amount of manufacturer and fabricator data sheets offers a one-stop advantage to any engineering firm. Removing any bottlenecks to the final engineering and owner approval milestones will improve the project permit and construction phase scheduling.
Reduction in engineering change notices ECN/ECR/ECO (or at least, pre-construction phase alerts) may be the greatest advantage to coordination of mechanical shop drawings. Engineering changes impact the entire design-bid-construction process on multiple levels. They usually entail modifications to products or assemblies, or changes in the construction process. As the percentage of ECN increases, projects experience a decline in productivity, cost overruns, and schedule delays.
A shop drawing coordination workflow actively supports either 2D design layouts or 3D and BIM models to discover and correct construction phase conflicts that have traditionally been detected only in the field. In a 2D layout, shop drawing coordination may reveal a large number of system clashes and point to areas that need to be modeled in 3D. Projects that are based on a 3D model will translate the design-level concepts into fabrication-level documentation. Three dimensional models streamline the entire coordination process by resolving connection issues and allowing details to be based on a comprehensive structural view.
Streamlined shop drawing submittal process which can include a vast amount of information from many vendors and fabricators, such as, assemblies, mock-ups, schedules, diagrams, technical specifications and product data information. Complex projects that keep graphical information detailing all mechanical room equipment installations under one general master guide is necessary to ensure efficient installation at time of construction.
Moving the shop drawing submittal process from an administrative duty to a full-service drafting and engineering firm puts this important ‘checks-and-balances’ phase into the hands of one familiar with the entire project. Incomplete documentation is reduced and accurate tracking of all required submittals can be maintained. In some instances, liability issues arise when required shop drawings have not been submitted, or if shop drawings incorrectly illustrate specific aspects of the installation. With mechanical room shop drawing coordination services, installation deviations and conflicts are identified to the design professional for acceptance or change.
Coordination meetings which include a set of coordinated mechanical room shop drawings allow all members access to accurate and expertly prepared drawings that have already been fully checked and system clashes eliminated, saving your engineers, architects and owner representatives valuable time. A mechanical room drawing set for coordination meeting purposes may include the following:
Consider outsourcing the drafting of your prefabricated pipe assemblies to document all pipe sections along with their connected flanges and fittings. You will benefit from decreased labor costs and save critical time spent in the field connecting and welding or bolting pipes and fittings. At INDBIM, we provide professionally drafted shop drawings of piping systems for the following utilities:
When you partner with an engineering drawing service to produce your piping shop drawings, you should expect a fast turnaround, but without sacrificing quality and accuracy. At INDBIM we draw your piping and plumbing shop drawings to fit you standards for annotation, dimensioning, and BOM tagging. We realize you have designed your piping layouts to be routed in the most effective manner, including slope of pipe and piping in congested areas. This makes it even more critical for shop drawings to be accurate in scale and orientation.
The accuracy of your piping shop drawings will affect equipment field connections by minimizing system clashes or interferences that result in costly field rework. If the shop drawings are not correctly dimensioned and detailed, then the equipment arrangement including nozzle locations on vessels may not match in the field.
Additionally, the correct types and sizes of welds must be clearly documented to make pipe spool fabrication easier for your chosen machine shop or fabrication vendor. Some construction projects depend heavily on piping systems and accurate pipe shop drawings. A few include:
The success of each of these construction projects will depend on the piping installations to run smoothly, because the success of the final structure depends on the flow of liquids and/or gases as a major building system. Instead of depending on an offsite fabrication shop to create your shop drawings, you will have an improved quality and a built-in checks and balances system when you outsource these critical drawings to a third party.
New facilities construction is not the only industry that requires pipe shop drawings. The aging infrastructure of municipal systems and private facility owners are failing across the globe. Often, a building’s structure is updated, but the plumbing and piping systems have been left as original when the facility was first constructed. This applies to any property over 30 years of age where various types of pipe material may be reaching the end of its service life.
Industries such as chemical processing or water treatment plants are experiencing a faster deterioration of their piping systems due to the use of cast iron, vitrified clay, or PVC piping that has begun to fail. Because a facilities’ pipes are often concealed, the condition of the system’s infrastructure can go unnoticed for many years. Leaks, corrosion, and blockages in pipes can cause more property damage than any other operating system in a building
