Does anyone have a good way of differentiating between 01 4336 Field Samples and 01 4339 Mockups? Thanks. Ronald L.

A field sample is a larger installation of a smaller submitted sample that typically involves the specified material and any accessory materials. Used primarily to determine quality of installation workmanship.

Most clients use the term Mockups when they mean Field Samples. Section 014339: 1.02 DEFINITIONS A. Mockups: Independent structures or installations, or assemblies that represent components of a portion of the facility or site work to demonstrate the coordination and interfacing of different products, such as a window assembly and adjacent wall construction. 1. Exception: Large wall enclosure assemblies installed directly on a building for approval of appearance, construction quality, or testing may be included under the category of mockups. B. Field Samples: Refer to Section 013300 for a general definition of Field Samples. Refer to Article: Field Samples in the various Sections of the Specifications for descriptions of in-place installations for review of materials and systems. 1. Note that these Specifications make a distinction between mockups and field samples. Section 013300: 3.1 2.04 FIELD SAMPLES A. Field Samples: Field samples are representative applications of finish materials on a limited portion of the facility or site to verify the aesthetic effect of a critical portion of the work or to evaluate the qualifications of the installer to complete the construction. 1. Where specified, prepare a field sample at a location on the site designated by the Architect. a. Where acceptable to the Architect, field samples may be actual portions of the finished work of this Section. B. Mockups: Refer to Section 014339.

I avoid field sample, and refer only to mockups. A mockup is an assembly built in place, and may include work results spec'd in a single section -- including a single material -- or a combination of materials. This avoids having to define terms for which the meanings are understandably confusing.

Even though the term field samples is often bandied about in a firm, it doesn't need to be used in the documents. With a description of what is required in each section requiring a mock-up, there will be no confusion as to expectations.

We refer to "Mock Ups" when there is a single trade mocking up. Common examples are decorative concrete, tile, terrazzo, or paint. Usually it is clearly understood that the mockup is not part of the completed work, but we also leave it as our choice as the Architect allow it to remain. We refer to "Composite Mock Ups" when multiple trades have to collaborate on making a mock up. Often the assembly is very complete such as an exterior wall assembly with perhaps only the interior side gypsum board omitted. These are never included in the completed work. The "Composite Mock Ups" I am referring to here are always site mock ups (for some other available place) for aesthetics and construct-ability. Mock Ups for off-site lab testing for fire, water intrusion, seismic, etc; are in a separate category.

Field site?). From MasterSpec 01 3300 - Submittal Procedures: 4. Disposition: Maintain sets of approved Samples at Project site, available for quality-control comparisons throughout the course of construction activity. Sample sets may be used to determine final acceptance of construction associated with each set. a. Samples that may be incorporated into the Work are indicated in individual Specification Sections. Such Samples must be in an undamaged condition at time of use. Although I would agree with Jeffrey and John; Call them mockups. No need to complicate things further.

These include everything that will be included in the space and may be fully operational as well. It's important to define the meaning(s) of the terms, no matter what terms you're using, so the contractor(s) know what your expectations are. Jerome J.

This has been true for Marriott, Hilton, IHS, Rosewood, Ritz Carlton, etc Louis Medcalf, FCSI, CCS Senior Member Username: louis_medcalf Post Number: 51 Registered: 11-2010 Posted on Friday, March 20, 2015 - 04:19 pm:    I think the term 'mock-up' should apply to stand-alone example construction that won't be incorporated into the work or to assemblies utilizing products from multiple sections that may [like room mock-ups] or may not become part of the final work. I just don't see that applying paint to one wall to verify appearance is a 'mock-up' and would prefer the term 'field sample,' but MasterSpec and a lot of other good folks use 'mock-up' for sample installations. I also prefer the hyphenated form 'mock-up,' which is supported by the online Merriam-Webster dictionary. Brian E.

So I have approx. 100 brick sent by the brick manufacturer to the jobsite and I build something. It might include the block backup. I tool the joints and probably clean down the wall. That something is used to verify the brick color and possibly for workmanship. What do I call that? I build another something, but this wall includes the brick, mortar, flashing, weeps, mortar net, wall ties and maybe a window. It is built to verify interfaces and possibly to develop a sequence for construction. What do I call that? My feeling is that I call the first thing a sample panel and the second thing is a mock-up. They are used for slightly different things although you could just build a mock-up and verify everything from that. Smaller or less important buildings don't do mock-ups, but a sample panel may be in order. Can I get everyone to agree that these are correct uses of the terms and that you need more than just the term mock-up? Just to add to the nitty-gritty. Would you ever call a mock-up a "mock-up panel" or is it just simply a "mock-up". ken hercenberg Senior Member Username: khercenberg Post Number: 950 Registered: 12-2006 Posted on Friday, October 02, 2015 - 04:50 pm:    Hi Brian! I've never seen an official definition of either so, as Lynn pointed out, a clear definition should be included in Division 01. Having said that, personally I use room mockups as noted above. I use the term mockup to typically mean a composite example of construction involving multiple products and trades so it would include back-up, flashing, weeps, cavity drainage materials, and probably a fenestration or louver. A sample panel would be an example of construction limited to the work of one trade and typically only for aesthetic purposes such as establishing the range of brick, cast stone, etc. As a stretch I might have an example of a stainless steel drip edge built in just to give my designer heartburn.

The CSI Construction Specifications Practice Guide has fairly definitions for field samples and mock-ups. Personally, I define them in Quality Requirements under the broader category of Representative Construction.
