Contract Scheduling and Terms

Disclaimer – this and subsequent articles on this subject are not intended to be legal advice, merely an example for discussions between you and your legal advisor.

Please keep in mind, many of these terms are applicable towards post frame building kits and would require edits for cases where a builder is providing erection services or materials and labor.

SCHEDULING: Upon completion of all required documents by Purchaser (including, but not limited to, Instant Invoice, Door locations and Jobsite Delivery Information), Purchaser’s online approval of Seller’s plans, and appropriate payment, shipment(s) will be expedited to be as soon as is practical, however no guaranteed time frame is promised. Purchaser will receive multiple deliveries over a span of a week or more. Seller has little or no control over the exact date of arrival, nor can Purchaser specify any exact date and/or time for deliveries.

Some vendors will require Purchaser or Purchaser’s adult agent to be present at time of delivery. Materials may be delivered via any combination of USPS, UPS, FedEx or freight carrier, the choice of which is strictly determined only by Seller and/or Seller’s vendors. In the event tracking information is furnished to Purchaser, the responsibility to monitor tracking is upon Purchaser.

EXCLUSIONS: Seller is not a contractor, architect or engineer in any state, and both parties agree no such representation has been made. Seller does not and cannot endorse, nor take responsibility for the performance of any contractor or laborer hired by Purchaser, even if the name was provided by Seller. Purchaser waives any and all right of claim against Seller for non-performance of any materials improperly installed by any contractor. 

Seller cannot predict nor guarantee any permit, construction or labor costs. Any and all construction labor and equipment, as well as nails 16d or smaller, staples or tacks which can be commonly driven by pneumatic powered equipment are to be provided by Purchaser or Purchaser’s agents. The need for butyl tape sealants, water seals, closures for wall steel or polycarbonate panels, caulking or any other sealants is to be determined and furnished by Purchaser. 

While great effort is made to include web bracing material Seller does not see final engineered truss drawings prior to shipment so cannot verify, in advance, all web bracing requirements. As such, any materials for web bracing required beyond what is originally shipped with building kit, shall be furnished by Purchaser. Seller also does not furnish, nor pay for, any cement, concrete, pre-mix, rebar, wire mesh or any other materials which would be used to backfill Purchaser’s building columns or to construct any concrete floor, foundation or curb.

Concrete floors and/or continuous footings and/or foundations, electrical, plumbing, HVAC, insulation, drywall, site or grading plans, non-structural interior walls or partitions, provision for flooding, firewalls, sprinklers or other fire separations, gutters and downspouts, energy/heat loss calculations, meeting requirements of any energy code, meeting requirements of The International Wildlife-Urban Interface Code, or materials not provided by Seller, as well as the design of or specifications for any concrete work (including but not limited to driveways, porches, approaches, slabs, retaining walls, footings for walls, continuous foundations or stem walls) are specifically excluded from this Agreement and provided plans and/or calculations to be provided by Seller or third party engineer(s). 

Seller’s plans include a foundation designed as an isolated, shallow foundation with embedded columns. In the event any other foundation type be desired, or required, Purchaser will need to hire an appropriate engineer, at Purchaser’s expense. Any “plot” plans, floor plans or site tests/reports/engineering, or other “special” reports requested by any agency for Purchaser’s building are to be provided by Purchaser. Stairs, lofts, decks, mezzanines, second or higher floors, if included, will have handrails provided by Purchaser, unless otherwise specified. 

Purchaser further agrees to not enter into any other agreement, either verbal or written, with any of Seller’s suppliers, manufacturers, agents, employees or subcontractors, without the express written consent of Seller.

Protection from Wildfires Part II

Yesterday I started the discussion of the International Wildland-Urban Interface Code –which spells out requirements for protecting buildings in case of wildfires.  So back up a day if you missed the first part of this. To recap a bit…

wildfire-protectionThe International Wildland-Urban Interface Code (IWUIC) is a model code intended to be adopted and used to supplement the adopted building and fire codes of a Building Permit issuing jurisdiction. The IWUIC has as its primary objective the establishment of minimum specific regulations for the safeguarding of life and property from intrusion of fire from wildland fire exposures and fire exposures from adjacent structures and to prevent structure fires from spreading to wildland fuels, even in the absence of fire department intervention.

Many Building Departments, which have adopted the IWUIC, have informational handouts which give guidelines as to how to conform to the requirements.

Below are the rest of the provisions which affect post frame (pole) building construction.

Vents: Attic ventilation openings, foundation or under-floor vents, or other ventilation openings in vertical exterior walls and vents through roofs shall not exceed 144 square inches each. Such vent shall be covered with noncombustible corrosion-resistant mesh with openings not to exceed 1/4 inch or shall be designed and approved to prevent flame or ember penetration into the structure. Attic ventilation openings shall not be located in soffits, in eave overhangs, between rafters at eaves, or in other overhang areas.

Gable end and dormer vents shall be located at least 10 feet from property lines.

This limits gable vents to 12 inches square or equivalent and should be metal rather than vinyl. With the elimination of eave vents, this means any required attic ventilation will have to be supplied via gable vents. Here is some discussion about ventilation requirements: https://www.hansenpolebuildings.com/2012/08/ventilation-blows/

Detached accessory structures: Detached accessory structures located less than 50 feet from a building containing habitable space shall have exterior walls constructed with materials approved for a minimum of 1-hour fire resistance-rated construction, heavy timber, log wall construction or constructed with approved noncombustible materials on the exterior side. When the detached structure is located and constructed so that the structure or any portion thereof projects over a descending slope surface greater than 10 percent, the area below the structure shall have all under-floor areas enclosed to within 6 inches of the ground, with exterior wall construction.

Exception: The enclosure may be omitted where the underside of all exposed floors and all exposed structural columns, beams and supporting walls are protected as required for exterior 1-hour fire-resistance-rated construction or heavy-timber construction.

Automatic sprinkler system: an approved automatic sprinkler system shall be installed in all occupancies in new buildings required to meet the requirements for Class I Ignition-Resistant Construction. The installation of the automatic sprinkler system shall be in accordance with nationally recognized standards. (Read more on sprinklers here: https://www.hansenpolebuildings.com/2011/07/benefits-of-a-sprinklered-building/ and https://www.hansenpolebuildings.com/2013/06/sprinkler-system/)

With some advance planning, a steel covered post frame building can relatively easily meet the requirements of the International Wildland-Urban Interface Code. For the most part, think- no non-fire treated wood exposed to potential wildfires.
