Commercial Steel Estimating. Kerri Olsen

СКАЧАТЬ this section, list the main framing members. Include the material grades as well as information regarding the connections and the finings of the steel. This sample letter style has the entire structural package all included in one bid item. A more specific breakdown is preferred, with a line item for each component of the building. The breakdown would also list the plan drawings with the applicable details, and drawing references with quantities as required. Indicate the type of finish to be applied to the material.

       Inclusion #2

      This bid item talks only about the steel stairs together with the catwalk and railing as a complete system. Note that the total linear feet of railing is indicated with the finish as being galvanized.

       Inclusion #3

      In this listing, estimators are specific about the fasteners being provided. This information is important because steel fabricators should not be responsible for supplying fasteners to be used for connection to other trade materials.

       Inclusion #4

      Estimators indicate that their quote includes the design engineering for the fabrication per some requirement in the documents. This information is important to note specifically because design engineering is an expensive item. For the most part, steel fabricators tend to omit this listing because the pricing can vary so much from engineer to engineer.

       Inclusion #5

      In this inclusion, estimators affirm that shop detail drawings will be provided inclusive of erection drawings. Some projects have the steel detail drawings already provided to them.

       Inclusion #6

      Advising potential customers of the total weight of the project allows them a frame of reference to better compare your quote with the other prices they get from the competition. Customers need to know about the shipping and offload point; it allows customers to better evaluate your quote with what your competition may or may not have.

       Note: Additional inclusion items may need to be listed according to the items requiring fabrication, as shown at the contract drawings.

Exclusions

      1.It is important to show clearly the exclusion of any additional costs associated with doing business. Taxes, sales taxes, bonding, and liquidated damages are all costs that are referenced in the general conditions. This exclusion eliminates any assumptions that might be made about their provision

      2.This exclusion prevents any assumption that the steel fabricator will provide holes in the steel for other trades to use. Such work by the fabricator is not shown in the contract drawings and cannot be assumed as part of the labor for your portion of the work. Excluding holes for other trades is a standard exclusion for every job.

      3.All light gauge materials less than 1/8” are a standard exclusion; the light weight materials are in a different section than the Division 5 (see explanation of Division 5 requirements in Chapter 4, The Bid Documents) that we are working with. Light gauge materials are often used for flashing, roofing, and cold formed metal framing.

      4.Framing for openings are usually shown as a typical detail. If the contract drawings specifically show locations and details for floor and roof openings, then it is clear the steel fabricator would include them. Typical roof opening details are a gray area because there usually are no references to them in the floor and roof plans. For this reason, they are excluded. Unit prices on fabricated items may be offered as an alternate.

      5.Field erection and all field welding are standard exclusions if the steel fabricator is not installing this finished product.

      6.Verification of missing dimensions is a standard exclusion designed to protect the steel fabricator from exposure to field work.

      7.This exclusion lets the contractor know that the steel fabricator is not including any costs for engineering.

      8.Costs for special inspection are picked up by the owner as a rule. However, because the specifications put the inspection requirement in the Division 5 section (see Chapter 4), it could be mistaken that the steel fabricator is responsible for paying for them.

      9.The section for metal floor deck and roof deck is in Division 5. Therefore, it is to be excluded if the steel fabricator is not providing this material.

      10.The nosings for stairs are a buyout item installed in the field at the time the concrete is poured. Customers do not need to have the steel fabricator supply something they can buy themselves, saving themselves the additional profit markup.

      11.Steel joists are also in the Division 5 section. Be clear whether or not they are included in your pricing.

      12.Both the grout for leveling the columns and the concrete fill for stair pans and landings are handled by others. They are standard exclusions.

      13.Steel shim material and backing plates are usually light gauge steel. The referenced sleeves are not sized at the specification; they could be light gauge as well, or any size for that matter. Steel fabricators have to be clear whether or not they are providing these items.

      14.Steel fabricators need to reinforce that they are not providing any special finishes to the steel.

      15.This category clarifies the provision of fasteners, which are a standard exclusion.

      16.Catch basins, manholes and manhole ladders, and trench drains are typically shown in civil drawings. The mistake is often made, however, that because the items are steel, the fabricator would have them. In most cases, these are buyout items that the general contractor provides.

      17.Downspouts and gutters are in the roofing section, although on occasion either they are designed with special attachments or the downspouts themselves are made from pipe that would be designated in Division 5. The mistaken assumption could be made that the steel fabricator will provide them. Thus, it is best to exclude them.

      18.Stainless steel, aluminum, and brass are all nonferrous materials. These items are considered metal by the designers and are included in Division 5 of the specifications. Not all steel fabricators get involved with providing the items that are not carbon steel. If steel fabricators are not providing these items, then this exclusion must be clearly stated.

      19.Rebar is an item that is included with the contractors providing the concrete and will be found in Contract Specifications Division 3, as explained in Chapter 4. This exclusion is standard, provided for clarity.

      20.Roof penetration framing is sometimes shown as a typical detail in the contract drawings. Typical details force assumptions to be made by the estimator. This exclusion then notifies the customer to look to the inclusions for advice on this provision.

      21.There are specialty companies that supply steel stud framing. There is a separate section at the project specifications that allows for provision of these items. This listing has been provided as a standard exclusion to be clear that the framing is not the fabricator’s/estimator’s responsibility.

      22.Insulated panels are provided by specialty companies СКАЧАТЬ
