Code Change No: G178-15

Original Proposal

Section: 602.4

Proponent: Sam Francis, American Wood Council, representing American Wood Council (sfrancis@awc.org)

Revise as follows:

Type IV. Type IV construction (Heavy Timber, HT) is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid or wood, laminated wood or structural composite lumber (SCL) without concealed spaces. The details of Type IV construction shall comply with the provisions of this section and Section 2304.11. Exterior walls complying with Section 602.4.1 or 602.4.2 shall be permitted. Minimum solid dimensions for building elements are as follows:

Solid sawn building elements shall be not less than the nominal dimensions are required for structures built using Type IV construction (HT)in Sections 602.4.3 through 602.4.6.
For glued laminated Glued-laminated members and structural composite lumber (SCL) members, members shall be the equivalent net finished width and depths depth corresponding to the minimum nominal width and depths depth of solid sawn lumber are required as specified in Table 602.4.Cross-laminated
Cross-laminated timber (CLT) dimensions used in this section are actual dimensions and shall be not less than the dimensions required in Sections 602.4.6.2, 602.4.7, and 602.4.6.8.2, as applicable.

Reason: In the last code cycle, the Heavy Timber section saw 5 code change proposals.  The correlation of these changes was very difficult. We are submitting several changes which are intended to make this chapter more understandable. One of the issues to be clarified is the "minimum dimensions of the exterior walls. Another item is to make it absolutely clear that Structural Composite Lumber of the minimum dimensions for this chapter is, in fact, considered heavy timber. So this proposal will point the user to the proper sections to accomplish these tasks.

Cost Impact: Will not increase the cost of construction
This is an editorial rewrite and will have no cost impact other than to lower costs by making the minimum requirements more clear.

Section: [M] 2801.1

Proponent: Edward Kulik, representing Building Code Action Committee (bcac@iccsafe.org)

THIS IS A 3 PART CODE CHANGE PROPOSAL. PART I WAS HEARD BY THE IBC GENERAL COMMMITTEE, PART II WAS HEARD BY THE IMC COMMITTEE AND PART III WAS HEARD BY THE IPC/IPSDC COMMITTEE.
Revise as follows:

The provisions of this chapter and the International Mechanical Code and the International Fuel Gas Code shall govern the design, construction, erection and installation of mechanical appliances, equipment and systems shall be constructed, installed used in buildings and maintained in accordance with
the International Mechanical Code and the International Fuel Gas Code structures covered by this code. Masonry chimneys, fireplaces and barbecues shall comply with the International Mechanical Code and Chapter 21 of this code. The International Fire Code, the International Property Maintenance Code,
the International Mechanical Code and the International Fuel Gas Code shall govern the use and maintenance of mechanical components, appliances, equipment and systems. The International Existing Building Code, the International Mechanical Code and the International Fuel Gas Code shall govern the alteration, repair, relocation, replacement, and addition of mechanical components, appliances, equipment and systems.

Reason: This proposal provides consistency in the scoping for the Electrical, Plumbing, and Mechanical chapters. Direction is provided as to what codes govern use and maintenance, and alteration, repair, relocation, replacement and additions for existing electrical, plumbing, and mechanical systems.
This public proposal is submitted by the ICC Building Code Action Committee (BCAC). The BCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance an assigned International Code or portion thereof. This includes both the technical aspects of the codes as well as the code content in terms of scope and application of referenced standards. Since its inception in July, 2011, the BCAC has held 13 open meetings and numerous workgroup calls which included members of the BCAC as well as any interested party to discuss and debate the proposed changes and the public comments. Related documentation and reports are posted on the BCAC website at: http://www.iccsafe.org/cs/BCAC/Pages/default.aspx.

Cost Impact: Will not increase the cost of construction
This proposal will not increase the cost of construction. This proposal may decrease the cost of construction, by providing clarity to the scoping of these chapters.
