9 Definitions ADDITION An extension or increase in floor area, number of stories, or height of a building or structure. CHANGE OF OCCUPANCY A change in the purpose or level of activity within a building that involves a change in the application of the requirements of this code. EXISTING BUILDING A building legally occupied or legally occupies prior to a current vacant status. REHABILITATION Any work, as described by the categories of work defined herein, undertaken in an existing building. REPAIR - The restoration to good or sound condition of any part of an existing building for the purpose of its maintenance. TECHNICALLY INFEASIBLE Same definition as NCBC Ch

10 Technically Infeasible TECHNICALLY INFEASIBLE Same definition as NCBC Ch Structural Signed, sealed letter from structural engineer 2. Physical or site constraints Document what this is + how it restricts the design 10

15 PRESCRIPTIVE NCEBC Ch. of Occupancy REMEMBER: some model code language is stricter than federal. FHADM (Type B) applicable to new construction after 3/13/91. This language changes the requirement based on the amount of work. 15

16 PRESCRIPTIVE NCEBC Partial Change This section is just above Complete Change in Occupancy Importance is that it references Alterations Alterations affecting a PFA (20%) Scoping for Alterations 16

17 PRESCRIPTIVE CHANGE OF USE PARTIAL CH OF USE NCEBC Complete Change The budget for all of this is included in the design and construction budget used to calculate the 20% disproportionate amount. None of this work is path of travel upgrades. Look carefully on others for EXCEPTION or not may be elsewhere. 17

18 PRESCRIPTIVE NCEBC Complete Change See NCEBC Ch. 2 for definition of TECHNICALLY INFEASIBLE. STRUCTURAL requires signed, sealed letter from Structural Engineer SIZE/SPACE justify inability to adjust requirements due to space constraints 18

32 HISTORIC NCEBC Alterations 32

33 HISTORIC NCEBC Exc. Type B Historic building in historic district Interior not historic this section is not applicable Designated historic building Historic interior < Level III alteration no Type B requirement (<50%) = Level III alteration Type B requirement (>50%) - The idea is: if the interior of the building is gutted, what goes back in will not threaten the historic fabric of the building. - There is no requirement for an accessible path from PROW to the dwelling entrance as that does affect the bldg. 33

34 HISTORIC NCEBC Site Arrival Pts Site arrival points. At least one accessible route from a site arrival point to an accessible entrance shall be provided. 34

38 Q & A and Examples 38

39 Path of Travel Upgrade Example Great example of simple Path of Travel upgrade often overlooked. 39

40 Level I or II Alterations BEFORE AFTER NCEBC or NCEBC Wall should be relocated to accommodate door clearance requirements with owner-supplied desk 40

41 Level III Alterations Q: The project is an existing 1-story auditorium with Level 3 alterations, including 1. Tearing down and replacing existing restrooms for the audience. 2. Providing a unisex facility that will serve the audience as well as the green room. 3. Increasing the size of the men s dressing room. 4. Cosmetic changes to the back of house area. 5. No work planned for the Men s and women s back-of-house restrooms other than paint and replacing the partitions between toilet compartments. If the toilet partitions are replaced, do the restrooms have to be brought up-to-code? There would be insufficient room to do this without losing fixtures. 41

42 Level III Alterations 1. Tearing down and replacing existing restrooms for the audience. [NCEBC Exc. 4] 2. Providing a unisex facility that will serve the audience as well as the green room. [NCEBC 806.1; NCBC ] 42

43 Level III Alterations 3. Increasing the size of the men s dressing room. [Design choice.] 4. Cosmetic changes to the back of house area. [By themselves, do not trigger upgrades] 43

44 Level III Alterations 5. No work planned for the Men s and women s back-of-house restrooms other than paint and replacing the partitions between toilet compartments. A: Proposed design work (men s dressing room) is what limits the ability to make the restrooms accessible. You cannot design away the requirement to upgrade existing restrooms + then claim technical infeasibility. Yes, the restroom upgrade is required. [NCEBC Exc. 1] 44

45 Partial Ch. of Use - Historic Q: The project is an existing building in an historic district that was originally one tenant and is now being subdivided into 7 tenant spaces; with bldg entrances off streets on E and S. M W 7 1. Original non-complying ramp removed and stairs added at Unit #6 entrance. 2. Units #4 + #5: have 3 historic sill, so step to sidewalk needed; finish floors 19 above the sidewalk; ramp provided at side entrances since not feasible at front NCEBC partial change of use NCEBC 1204 historic references NCEBC 806 and nd floor and stair access to 2 nd floor not involved in tenant alterations. 45

46 Partial Ch. of Use - Historic First, need to consider who is responsible for the work? 1. Will it be done by the tenant? If so, path of travel is limited to tenant space. 2. Will it be done by the landlord? If so, path of travel applies to entire building. M W 7 Second, how historic is the building? 1. If historic district only, then NCEBC 806 /906 are applicable. 2. If historic interior also, then use NCEBC through where compliance with the following would threaten or destroy the historic fabric of the building per the SHPO. No Type B dwelling 1 units required in historical bldgs.* NCEBC Site arrival Multilevel bldgs. + fac. Entrances Bathing + Toilet Facilities 46

47 Partial Ch. of Use - Historic In this case, the landlord is responsible for all and only the exterior is historic. Everything within the building complies with NCEBC and Exterior building envelope uses NCEBC Site Arrival + NCBC Entrances M W Since the basic requirement is NCEBC that references NCBC Ch ANSI A Don t forget ANSI Table for historic thresholds. 47

48 Partial Ch. of Use - Historic Tenant #6 existing ramp proposed to be replaced with a stair entrance: Existing ramps, even non-complying ones, cannot be replaced with only stairs [NCEBC 410.3] Ramp is required unless SHPO documents it threatens or destroys historic fabric of building [NCEBC NCEBC ANSI 403.4/303] All of this is Historic Bldg-Exterior, so has to be approved by SHPO 48

49 FROM 1999/2002/2004 NCAC NO CHANGES IN 2015 NCEBC FROM WHAT IS BELOW Example STRATEGY 1) Start with overall budget. 2) Subtract non-alterations: System-related work Maintenance work [ Work in non-primary Function areas] 3) Determine 20% 4) Develop cost estimates in order of priority 5) Get Budget Analysis from Owner/Contractor/Arch 6) Perform all work up to disproportionate amount When this is the sole scope of work

50 Work Performed w/in 3 Years Important for owner (and designer) to keep track of budget and expenditures
