Investigation and Analysis
Client:
Marney Electric
175 Main Street, Leeds
Northampton, MA 01053
General
The former Alternative Recycling Systems offices shall be occupied by Marney Electric as their new headquarters. No additions are proposed, but some interior modifications shall be
made to facilitate occupancy. These modifications shall meet relevant codes. The building is a steel framed building with insulated steel siding, interior CMU and wood-framed walls,
thus Use Group B with some storage S-2 and Type III B construction. I have reviewed IEBC 2009, Chapter 3 Prescriptive Compliance Method. There are no exterior modifications proposed
except installation of a cantilevered entry canopy and the lot has extensive existing paved parking and 20 feet wide access around the building. Here I will list relevant sections
from code.
IEBC 2009
301.2 – materials = existing (no dangerous conditions noted); new shall meet code
303 – alterations
303.1 exception 1 – existing stairway may remain in use where existing space and conditions constrain alteration (offices stair to remain)
303.5 – voluntary seismic improvements = the steel building is well braced and new interior walls shall be independent of the main structure; any steel alterations shall be carefully
considered to increase bracing
306.1 – glass replacement = shall meet code as new
310 – accessibility – no modifications proposed; accessible path provided from main entry thru public areas to rest room (not modified or compliant; could be made compliant in the future)

310.8.1 – entrances = the main entrance shall be compliant
310.8.4 – stairs where none existed = the new stair to the new second level of the east portion shall be compliant with proper width, rise, run and handrails
310.8.11 – toilet rooms – currently provide 2 with non-compliant door width and without grab bars; no modifications proposed. one poorly constructed raised
lavatory is to be removed. Request Code Compliance Alternative to allow continued use of existing lavatories.

508.3 – non-separated occupancies – since each (B and S-2) type of occupancy is well below allowed thresholds, there is no plan to fully separate occupancies
602.3 – Type III construction B, unprotected
Table 601 – IIIB 0hr exterior; bearing walls 2hr – 2 layers of 5/8” type X gypsum shall protect the new 10” wall to support the new second floor and the stair wall

(B = 1227sf/100 = 13 + 4331sf/300 = 15; total 28 people) – the designated areas were incorrect; the Storage and Showroom and Flexible Space – Staging will be employee only Staging areas
and were so designated in order to bring the public to the rear restroom which does not work as the restroom is not accessible and requires noncompliant level change
