In recent times huge crowds have been taking a look at the New York Engineers website in search of Architectural Engineering near the Chicago area. That is due primarily due to the reputation we have built in this kind of work. However, a lot of builders from Kenilworth to Wheaton, Illinois, don’t know that NY-Engineers.Com is also a top contender for anyone looking for HVAC Chicago.

The quest for cost effective buildings involves cost effective HVAC system design. This may include systems for HVAC, lighting, architectural enclosure, domestic water heating, and vertical transportation. The loads for your HVAC systems can come primarily from five different places including lighting (cooling), the construction envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will certainly be a purpose of either the devices required in an attempt to introduce it in to a space and control contaminant concentration or the number of people who will be in the area. In the vast majority of climates in the eastern and southwestern regions of the united states, to lower outter air-flow will save energy whenever the exterior air is either warm and humid or very cold.
Managing the ventilation rate will likely be determined by occupancy which is known as a form of demand control ventilation. This can be a everyday sort of energy conservation approach that is used for spaces with occasional or crowded occupancy. Having cooling and heating loads reduced to a minimum can be accomplished through the use of a high performance building envelope, occupancy sensors, and high performance lighting that apply daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Technicians

When you’ve ever wondered about the difference between a HVAC Engineers versus HVAC Engineers, then continue reading:

HVAC engineers would be the people that manage installing of air cooling systems both for commercial and residential buildings. They spend a great deal of their time in offices doing higher-level management and preparation of installations but they do also go to job sites every now and then.

On the other hand, HVAC technicians usually do a lot of the hands-on work with repair and maintenance. A HVAC technician may work with or for an engineer to complete several of the installation work, especially on smaller jobs. Generally HVAC techs do far more travel and may spend time and effort changing filters, identifying leaks, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers could possibly have the opportunity to make more decisions about systems that are being used, and they are the folks that would offer assistance with the most sensible refrigerants and which systems would be perfect for a larger building. In the industry, there may be some conflict between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs do require an effective familiarity with how air conditioning really works. As of late a lot of Internet users have been browsing our sites searching for HVAC Companies Chicago. Nevertheless, the goal of our firm is to be the to go to firm for those searching for a HVAC Chicago and or any of our other services including Electrical Engineering Engineering services. We ask that everyone looking for additional info about our Heating and Air Conditioning (HVAC) Engineering Firm in Chicago Illinois stops by at our Mechanical Engineers blog

How to Select a Contractor for Mechanical Engineering Projects

Architectural Engineering Vs Architecture

Tips for Effective Contractor Selection in Engineering Projects

One of the key elements that determines project success is selecting the right contractor for the job. Although it may be tempting to focus on minimizing cost, a better approach is to maximize value and optimize cost. After all, a mechanical engineering project of any kind is an investment; the best offer is not always the one with the lowest price, but the one that offers the highest return on each dollar spent.

Effective communication is key during the bidding process: if the participating contractors understand the project requirements clearly, they can craft their proposals accordingly. Without proper specifications, even the most qualified contractors may struggle to provide a suitable offer. Effective communication is so important for project success, that the Project Management Institute dedicates a whole chapter of its Body of Knowledge to the topic.

Before proceeding with a bidding process, hiring an engineering consulting or supervision firm is highly recommended. They can help you expedite the process, while providing technical guidance and managing correspondence with contractors. Even with a clearly defined project scope, it is normal for contractors to request additional information or clarifications.

Bid Leveling: Setting a Common Ground for Comparison

Project bids can only be compared with each other if the contractors are quoting the same scope of products and services. When sending a Request for Proposals (RFP), include a scope document that breaks down the work into specific items, and where each item is priced individually. This allows bids to be compared side by side, something not possible when each contractor provides a different breakdown of the project work.

Creating a detailed project scope consumes extra time at the beginning but saves much more time later in the process. Since bids can be directly compared to each other, communication becomes more effective during the contractor selection process, reducing the number of clarifications and requested corrections.

The Project Management Institute (PMI) recommends using a Work Breakdown Structure (WBS) to define project scope. In simple terms, a WBS decomposes the project work into a series of levels, where work definition becomes more specific for each descending level, and specific project items are described at the lowest level. The following is an example:

  • A construction project WBS may have a category called Electrical Installations(Level 1).
  • That category can be subdivided into sections such as Lighting Installationsor Electrical Receptacles (Level 2).
  • Specific lighting fixturesare specified in the lighting installations section, as well as their required quantities (Level 3). For example, an item in the list can be described as: Recessed Commercial LED Fixture, 2ft x 4ft, 4000 lumens, clear white light (4100K). This is an item that can be priced specifically by the contractors participating in the bid.

A list of items that is broken down by categories and subcategories is much easier to understand than a plain list where elements from different building systems are combined. An engineering consulting firm can help you put together a WBS effectively. With this bidding format, detecting discrepancies also becomes easier; for example, if five contractors are participating and one of them priced an item significantly lower than the other four, it is likely that there was a mistake or misinterpretation.

Importance of a Mechanical Engineering Professional’s Technical Point of View

When comparing bids for a project, the opinion of a neutral and qualified third party is highly recommended, and the best recommendation is to hire the services of an engineering consulting or supervision firm. This way, each item on the project scope can be assessed based from the financial and technical standpoint in relation to mechanical engineering, ensuring that the price provided by a contractor is reasonable according to technical specifications. To define what can be considered cheap or expensive in engineering, a degree of industry know-how is required.

An engineering consultant or firm can also determine if any items in the project scope are priced too high or too low, and then request a clarification from the respective contractor. Low prices are only good news if they are reasonable; unrealistic prices are likely the result of a mistake by the bidding contractor. However, these conclusions can only be reached with a thorough understanding of different building systems and the prices that can be expected.

Equipment Submittals

In simple terms, submittals can be defined as any information on equipment and materials, provided by a contractor for approval before the project is awarded. Some of the most common types of submittals include technical cut sheets, shop drawings and material samples.

Building system components must generally meet a series of requirements and standards. Equipment from reliable manufacturers comes with technical cut sheets, which provide a detailed description of product features and compliance. However, not all contractors work with the same providers, and the contractor selection process may involve comparing equipment from different suppliers for a single item in the project bid. Although equipment cut sheets are available in the Internet, searching for them can be very tedious when dealing with a large project. For this reason, it is very important the contractors participating in a bid provide cut sheets of all the proposed equipment.

Some elements of building systems that perform critical functions or involve a high degree of complexity cannot be described effectively with only textual specifications and general construction plans. In these cases, requesting shop drawings from contractors is recommended, providing specific details on how the component will be manufactured or installed. Shop drawings are especially important in projects that involve custom-built components.

In some projects, it may also make sense to request material samples from the participating contractors, generally with the test results from a qualified laboratory. This is common with concrete, for example, due to how important it is for the structural integrity of a building.

Project Plan: Defining the Timeframe

Contractor bids must clearly define what will provided and at what price, but it is also necessary for them to determine timeframes. This provides a baseline against with the project owner can assess progress, and it is also useful for scheduling intermediate project payments. Completing a project successfully generally involves a detailed planning in terms of time, resources and cost.

  • Time: Many project activities follow a logical sequence. For example, roofing installation can only proceed if the underlying structure is already built, and painters must wait for the walls to be completed. A Gantt chart is the best tool for showing the sequence of project activities and their completion times, and it also allows the identification of critical activities that delay the whole project if delayed individually – noncritical activities have a slack time, and can be delayed to a degree without compromising project completion.
  • Resources: Engineering projects involve personnel and equipment, and in a well-planned project the contractor knows from the start the activities in which these resources will participate at a given time.
  • Cost: After a contractor has developed a Gantt chart and priced each activity, it is possible to estimate a cost calendar. This provides the client a clear idea on how the project budget will be used over time, allowing payments to be scheduled more effectively.

The Project Management Institute places high emphasis on project planning, since it provides a basis against which project progress can be compared in terms of scope, time and cost. When comparing bids from different contractors, verify that timeframes and resource allocation are realistic. A bid can meet all project requirements at a reasonable time, while still being lacking in terms of planning.

Conclusion

When carrying out a mechanical engineering project, avoid awarding the job blindly to the contractor with the lowest price. Keep in mind that building systems must meet a series of standards, and there is a limit to how low a specific system can be priced. Also make sure that all bidding contractors provide a detailed project plan, providing details on their expected project timeframes and resource allocation
