Lately huge crowds have been taking a look at our website looking for Construction Engineering in or near the Chicago area. That is due primarily due to the reputation we have built in this kind of work. Nevertheless, many building owners from Carol Stream to Worth, Illinois, are not aware that NY Engineers is also the ideal choice for anyone searching for HVAC Chicago, Illinois.

The search for energy-efficient buildings involves power efficient HVAC system design. This will include systems for architectural enclosure, domestic water heating, lighting, HVAC, and vertical transportation. The loads for the HVAC systems can come primarily from 5 different bases including lighting (cooling), the property envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a purpose of either the devices required to be able to introduce it into a space and control contaminant concentration or the quantity of people who will occupy the area. In virtually all climates in the eastern and southwestern parts of the united states, to reduce outside air flow will save energy whenever the

outside air is either humid and warm or very cold.
Governing the ventilation rate will probably be dependant upon occupancy which is called a kind of demand control ventilation. It is a everyday sort of energy conservation plan that is utilized for rooms with irregular or dense occupancy. Having cooling and heating loads dropped as low as possible can be achieved by using a high performance building envelope, occupancy sensors, and high performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

If you have ever thought about the distinction between a HVAC Engineers vs HVAC Engineers, then keep reading:

HVAC engineers will be the folks that run the installation of air cooling systems for commercial and residential buildings. They spend plenty of their day in offices doing higher-level supervision and planning of installations nonetheless they do also see job sites every once in awhile.

But, HVAC technicians in Chicago usually do a lot of hands-on work with repair and maintenance. A HVAC tech may work with or for an engineer to perform several of the installation work, specifically on smaller jobs. Generally speaking HVAC technicians do a lot more travel and may even spend time and effort identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers could have the ability to make more decisions about systems that are being used, and they are definitely the folks that would offer advice about probably the most sensible refrigerants and which systems would work best with a greater building. In the industry, there is some challenge between ‘the suits’ and ‘the ones that will get their hands dirty’, but both jobs require an effective knowledge of how air-con works. As of late many people have been reading the NY-Engineers.Com site searching for HVAC License Chicago. With that said, the focus of our organization is to become the to go to firm for those searching for a HVAC Chicago and or any of our other services including Sprinkler Design Engineering services. We ask that those searching for more details about our Heating and Air Conditioning (HVAC) Engineering Firm in Chicago Illinois takes a look at our blog…

How to Select a Contractor for Mechanical Engineering Projects

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
