Briefdescriptionofbuildingprojectbeingusedforassessment:
TheBuilding
The building consists of a single storey portal-framed structure that is founded on a reinforced concrete foundation. Lower level external walls consist of pre-cast concrete panels to a height of 2.5 metres with long-run profi led metal sheet cladding fi xed to steel framing above. Offi ce areas are clad with fi bre cement-based sheet on a drained cavity. The roof is clad with long-run metal sheet. The roof design incorporates a small building-plant area, which will house the building’s air-conditioning system. Internally the building is divided into two large open retail spaces, a warehouse with goods stacked in proprietary racking systems (higher than 3 metres) and a drive-through timber yard area. Two small mezzanine areas are provided for staff offi ces, bathrooms, lunch and meeting rooms.

The applicant listed the following specifi ed systems on the form 2 building consent application:
• Automatic sprinkler system• Emergency warning system • Emergency lighting system• Mechanical ventilation (air-conditioning) • Backfl ow prevention• Means of escape (fi nal exits, fi re separations and signage)
Describeinyourownwordswhatyouconsiderisimportantinrelationtothefollowingaspectsofyourbuildingproject.
1.Site/landthatbuildingisbeingbuilton:
The site includes the following special features.
a. GIS mapping indicates the site is located within a specifi c design wind zone. The design engineer confi rmed this view by calculating the site’s wind speed to be 56 m/sec (designated specifi c engineered design (SED)). Structural design, loading calculations and material selection have all taken the sites relative wind loading into consideration.
b. The geotechnical report has identifi ed the site as generally having good ultimate soil bearing capacity; however a small portion of poor quality soil has been identifi ed at the southeastern end of the site. This localised area of poor ground requires specifi c strengthening attention to ensure the building platform can support the load-path from the super structure; consequently a condition has been added to the building consent under section 90 of the Building Act 2004 for third party verifi cation (PS4 monitoring) of this building work as we do not have the specifi c in-house competency to undertake such monitoring or soil testing. The design engineer responsible for observation work is well known to the BCA and is a practising CPEng.
c. The site is rural and is in zone 2 as defi ned in NZ S 3604:1999, indicating building elements are unlikely to be affected by accelerated atmospheric corrosion from wind blown salt laden air and the like.
d. The site has no easements, encumbrances, consent notices etc listed on the certifi cate of title. So no specifi c limitations/design modifi cations are necessary in this regard. Council records also indicate that the site does not have any land related issues such as hazards, contamination or heritage status etc.
e. A surveyor has been involved in defi ning the allotment’s boundaries, so boundary clearances etc should be relatively easy to establish on site.

2. Foundations:
Basis for design: AS/NZ S 1170:2002, B1/VM1 and B1/VM4
The building’s foundation is fully engineered and will be monitored at specifi ed times during construction (some specifi c soil testing is required to confi rm design assumptions made regarding poor soil quality at the southeastern end of the site).
The slab ’s DPM is well detailed on plan and within the specifi cation and meets the E2 performance requirements.
Perimeter pre-cast concrete panels are to be welded to base plates that are to be tied into the slab.
Other aspects of the foundation design were considered standard for this type of building work eg concrete strength, ground clearances, shrinkage control joist, steel size, steel cover and lap, DPM etc.
Some services are to be run within the slab, but this is covered in item 6 below.
3. Structureofthebuildingfromfoundation/slabup:
Basis for design: AS/NZ S 1170:2002, B1/VM1
The building’s structural frame/skeleton consists of steel portals and steel horizontal girts that are clad with long-run metal sheet cladding. Pre-cast panels extend 2.5 metres above fl oor level around the perimeter of the slab.
Plans and specifi cations for the project indicate the building structure (roof) is to support the weight of some large air-conditioning units. The air-conditioning units do not feature in any of the design engineer’s sketches and it is unclear if she is aware of the additional super-imposed load associated with these units (a phone call was made to the engineer to confi rm that the design had accounted for the additional loading imposed by these units). The engineer confi rms these units were not included on the plan version she was provided with. As a result the roof loading is recalculated and the units are moved to a more suitable location (amended plans were requested and provided). Fixing details were also requested for securing the units through the roof cladding in order to satisfy clause E2.
4. Buildingenvelope(claddings):
Basis for design: E2/VM1 and E2/AS1 modifi ed and used as an alternative solution for Building Code compliance.
The building is outside the scope and limitations of E2/AS1; however the designer has chosen to use some design principles and fi gures within the Acceptable Solution to prove compliance with clause E2. Given that the site is located in an SED wind zone and the designer has provided junction details that were unconventional it was decided to get the design peer-reviewed by an independent expert. The design was peer-reviewed by a recognised weathertightness expert who confi rms that the building meets clause E.2.3.2. The designer also provides in-service history of a similar building design that is subject to the equivalent wind pressure. A combination of in-service history and expert opinion confi rms the design meets clause E2 of the NZ BC on reasonable grounds.
5. Firesafety:
Basis for design: C/AS1
Active systems included: Basis for compliance
Automatic sprinkler system NZ S 4541:2007
Emergency warning system F7/AS1 NZ S 4512:2003
Emergency lighting system F6/AS1 AS/NZ S 2293:1995
Passive systems included:
Means of escape (fi nal exits, fi re separations and signage) C/AS1
The building is located at least 20 metres away from any boundaries and no other buildings are in close proximity, so spread of fi re beyond the building is unlikely.
The applicant provided a fi re report that used the Compliance Documents Acceptable Solution C/AS1 to illustrate compliance with the NZBC. In line with our BCA’s policies and procedures our lead technical person for the C-Docs (John de-blaze) peer-reviewed the fi re report and associated plans. The internal review confi rmed my fi ndings and agreed the documents met the requirements of C/AS1 and the NZBC.

6. Services:
General All services penetrations were checked to have adequate protection (eg, fi re collars, structural support, not compromising sound rated walls etc).
P&DDrainage and plumbing services for clauses (E1, G1, G2, G10, G12 and G13) were assessed by the BCA’s technical person (S Bend). A small issue was identifi ed regarding pipe falls for sanitary services in the slab (pipe falls within the slab were not adequately detailed on plan). S Bend contacted the designer and the appropriate falls were entered on the relevant drawings. Other P and D matters were found to comply with NZ BC.
Prescribed gas and electrical work Covered by an energy work certifi cate (providing a copy of these certifi cates is a condition of the building consent).
Specifi ed systemsIn accordance with section 7 of the Building Act the designer provided a list of the specifi ed systems to be installed in the building and the proposed procedures for inspection and maintenance of those systems. A schematic plan was also appended to this information to help with on site inspection and system identifi cation purposes.
Third-party commissioning certifi cates are required for the installation of the alarm and sprinkler systems (providing this verifi cation/certifi cation were made on condition of the issued building consent).
7. Interiorfinishes:
Spread of fi reFire resistance ratings and surface fi nishes were assessed and peer-reviewed as part of the fi re safety assessment. These items were found to meet the NZ BC.
Slip resistance The designer elected to use materials that met the slip resistance requirements detailed in D1/AS1 (eg, friction coeffi cient of not less than 0.4).
MoistureWet area fl oor and wall services were well detailed within the design documents and generally used E3/AS1 as means of compliance, albeit with a few minor alternative solutions (the design of a level access accessible shower was deemed beyond the scope of the acceptable solution as it used a sheet membrane on fl oor and wall surfaces; however, the design was found to be well detailed and deemed to meet the requirements of E3).
Describeinyourownwordstheareasofthebuildingthatyouconsiderarisk:
• Foundation – the geotechnical report identifi ed areas where poor soil quality was present.• Structural – building plant located on roof (air-conditioning units) • Building envelope – potential for water ingress and alternative solution offered as a means of compliance • Services – penetrations through fi re rated walls, specifi ed systems – correct design standards and inspection and maintenance
requirements. Pipe services in slab did identify falls/gradient.
Why?:
• Foundation – potential for localised building failure due to poor ground conditions. • Structural – potential for building failure due to an unsupported point-load that was not addressed during the design phase.• Building envelope alternative solution offered by applicant was viewed as potential area of weathertightness risk (peer-review requested
to support proposed design).• Services – penetrations through fi re walls create the potential to compromise fi re resistance.

Final inspection for commercial level 2 type building work.
Objective: ensuring the building work has been carried out in accordance with building consent – plans and specifi cations and any amendments, minor variations undertaken during the project and meets the NZ BC requirements.
A review of the consent fi le was undertaken before visiting the site to familiarise myself with the status of the project and identify if there were any outstanding compliance matters.
The project manager responsible for managing the development asked that he be present during the inspection. This was agreed to as it was felt it would be benefi cial should any queries arise about technical matters.
A separate fi nal inspection covering P&D compliance is to be undertaken.

1. Site/landthatbuildingisbeingbuiltoninrelationtotheinspection:
• As the site is located in a specifi c design wind zone (subject to higher than normal wind pressures) and has some unconventional cladding design details have been used. I will place particular emphasis on inspecting these aspects as it is important to ensure the building’s external envelope has been completed in accordance with plans and specifi cations.
• The site’s geotechnical report identifi ed specifi c requirements for certain areas of the site. As a consequence the project manager has agreed to provide copies of the engineer’s inspection notes and a (PS4) to confi rm the building work undertaken meets the Building Code (means of compliance: Verifi cation Methods cited in the Compliance Document for B1).

2. Structureanddurabilityinrelationtotheinspection:
• As noted above the engineer’s inspection notes and (PS4) are to be provided during the inspection to confi rm compliance in relation to structural matters conditioned on the building consent.
• A visual inspection of completed work was undertaken to ensure visible fi xings, ties, bracing etc are in place and are compliant. This was not done to redress items already inspected during preline/postline inspections. It was simply undertaken as general observation of the building’s overall structural compliance.
• I inspected the building for any evidence of structural movement, settlement, subsidence, warping, compression etc that would raise concern and may require additional investigation. No such issues were evident.
• A visual inspection of external/internal materials and coatings was undertaken to ensure these items met the plans and specifi cations and the Building Code, in particular clauses B1, E2 and B2.
3. Buildingenvelope(claddings)inrelationtotheinspection:
• I ensured the external envelope had been completed in accordance with building consent (plans and specs). As the building work includes alternative solutions used as a means of compliance, more emphasis was placed on the inspection of unconventional details, such as junction fl ashings between different cladding types. As an additional precaution, internal moisture level readings were taken on internal lined wall surfaces to provide additional support for the end compliance decision.
• I visually checked exposed fl ashings, membranes, cavity vents and drainage and kept an eye out for any un-consented attachments to the building envelope.
4. Firesafetyaspectsofthebuildinginrelationtotheinspection:
• A full walk-through inspection was undertaken to ensure the nominated means of escape was compliant and penetrations to fi re walls were sealed and made good.
• Life-safety systems (specifi ed systems) were confi rmed to be operational. Third-party verifi cation/certifi cation and commissioning information was provided to confi rm the fi re alarm and sprinkler had been installed in accordance with specifi ed NZ Standards (eg, NZ S 4512:2003 for the alarm system).
5. Servicesandassociatedsystemsinrelationtotheinspection:
• P&D inspection is to be undertaken by a BCO with the appropriate P&D competencies (not part of this inspection).• The fi nal inspection revealed that the following specifi ed systems had not been identifi ed during the processing stage of the building
consent. The owner had failed to identify the following specifi ed systems within their application for building consent – smoke control system for removing smoke and a CO detection device for early warning of gas leakage. Both specifi ed systems were located within the car park area of the building (refer to attached photos 1 and 2 for details of these specifi ed systems). Further information was requested regarding the installation, performance, inspection and procedural requirements of these specifi ed systems. Note: The fi nal inspection was failed as a result of this fi nding.
• The project manager was informed of the areas of non-compliance (non-consented building work) and was provided with an inspection report that outlined what was required to resolve these matters (amended plans and specifi cations, and performance, maintenance and reporting procedures for each specifi ed system). The project manager acknowledged the importance of getting these matters resolved and forwarded the information required, which in turn was added to the compliance schedule.
6. Interiorfinishesinrelationtotheinspection:
• Inspection of these elements was undertaken during the inspection of means of escape (in item 4). This included a visual check of fl oor, wall and ceiling fi nishes and fi xtures and fi ttings to ensure they comply with the plans and in particular the fi re report.

Why?:
• Foundation – potential for localised building failure due to poor ground conditions. • Structural – super-imposed load to roof could create issues if not correctly designed and/or installed.• Building envelope – the alternative solution offered by the applicant was viewed as potential area of weathertightness risk.
Unconventional design means checking of building envelope is very thorough. • Services – penetrations through fi re walls create the potential to compromise fi re resistance. • Specifi ed systems that are not picked up during a building consent will not end up on the buildings compliance schedule and will
consequently not get inspected and maintained over the life of the building.

10 Smith St, BC 001010
Briefdescriptionofbuildingprojectbeingusedforassessment:
This building is a single storey, monopitched (fl at roof less than 10 degrees), dwelling. The structure of the building is constructed generally in accordance with NZ S 3604:1999. The risk matrix score for this building is 7. The cladding consists of weatherboard (Linea®) and fl at sheet (Axon®) fi xed over a cavity and is generally in accordance with E2/AS1 and longrun corrugate roofi ng. However, the Linea® weatherboards are technically an alternative solution to E2/AS1.
Describeinyourownwordswhatyouconsiderisimportantinrelationtothefollowingaspectsofyourbuildingproject:
1. Site/landthatbuildingisbeingbuilton:
The site has been subdivided and had a geotechnical report and specifi c requirements for certain areas of the site. The geotechnical report requires the western foundation to be deeper due to it being located in close proximity to a sloping bank and the reduced compaction of the ground in this area.
The council ’s GIS register notes that this site is located in a very high wind zone however the designer has provided a wind zone assessment to NZ S 3604: 1999. I have focused on this as it is a site constraint that may affect the structure. I agree that the site is in a high wind zone.
Another aspect is that councils GIS register notes that this site is within the sea spray zone; however, the designer has provided evidence that the most western side of the site is actually just outside the sea spray zone by a few metres. I agree that the site is outside the sea spray zone as stated in NZ S 3604:1999.
2. Foundations:
As discussed above, due to one side of the building being located in close proximity to a sloping bank and the reduced compaction of the ground in this area a specifi c design aspect of the foundation was required. This specifi c design aspect is simply a deepening of the foundation using mass concrete as described in the engineer’s design.
The non-specifi c design foundation is to NZ S 3604:1999 and consists of 2x D12 with D10 starters at 600 mm c/s. The foundation requires 20 mpa concrete (note: not in a sea spray zone). Standard 200 series concrete blocks and header blocks are proposed, laid to the required fl oor level (no minimum fl oor level is required except the standard requirement of E1/AS1 to be above the crown in the road).
The fl oor slab is supported by compacted hardfi ll within the outer perimeter formed by the concrete blocks in max 150mm layers. A vapour barrier consisting of 0.25 polythene with taped joints. A perimeter bar (D12) is shown tied into the starters through the blocks bent over allowing 665 mesh to be placed over the starters.
3. Structureofthebuildingfromfoundation/slabup:
The building structure is generally in accordance with NZ S 3604: 1999 and includes some aspects of specifi c design, such as the garage lintel, trusses and lounge rafters. The timber frames consist of 100 mm x 50 mm MSG 8 at 600 mm c/s treated to H1.2 for the 2.4m high ceilings. Where the ceiling is more than 2.4m, 150 mm x 50 mm placed at spacings ranging from 400 mm to 600mm.
Particular review of the lounge rafters were assessed due to their length. These rafters were designed using the ganglam charts. A parallel girder truss supports the span over the lounge and the loads are transferred to the external foundation through double studs. A roof manufacture’s buildable design is included in the plans and specifi cations (from Mitec).
4. Buildingenvelope(claddings):
The cladding for this building is Linea® weatherboard and Axon® sheet. These products are fi bre (cellulose) cement based claddings and are installed over a 20 mm drained cavity all round. The roof is considered a fl at roof for the purposes of E2/AS1 as they fall below 10 degrees for both areas of roof.

4. Buildingenvelope(claddings):
The Axon® cladding is vertically joined over a 50 mm inseal strip and the cladding itself has a rebated edge to provide approximately 10 mm coverage (lap). The Linea® weatherboards are tongue and grooved at the ends and are joined by placing a bead of silicone in the groove and inserting the tongue end from another length of weatherboard. The corners of the weatherboard are fi tted with corner soakers and the internal corners are butt jointed into either a purpose-made internal corner fl ashing or butt jointed against the Axon® sheet. All internal and external corners are back-fl ashed.
All openings are fl ashed with a proprietary aluminium fl ashing and all openings in the building paper (air and moisture barrier) are taped and fl ashed with a fl exible waterproof membrane.
Details of all cladding junctions, openings and fl ashing requirements have been provided and are deemed to meet the requirements of E2.
5. Passivefireprotectionsystems:
No passive fi re protection systems were involved with this building; however, an active system is included that consists of a hardwired smoke detection and alarm system (early warning device) and was deemed to comply with Clause F7.
6. Services:
Drainage is 100 mm PVC installed to AS/NZ S 3500 to an existing connection to the council main sewer. Stormwater is disposed of on site as no public stormwater connection is provided. Plumbing is mains pressure polybute system installed to G12/AS1 and includes a mains pressure electric 180L HWC. Cooking is gas supplied via a 9kg bottle located outside and piped to cooker. Electricity, phone and gas (not yet supplied to the area) are supplied to the site.
7. Interiorfinishes:
The interior is lined with Gib® plaster board. Aqualine Gib® is detailed to wet areas. The fl oor is carpeted in the living areas and vinyl in the dinning room and kitchen and both bathrooms (wet areas). The vinyl in the wet areas is coved to comply with E3/AS1. Surfaces to the kitchen are easily cleanable and impervious.
Describeinyourownwordstheareasofthebuildingthatyouconsiderarisk:
1. Foundation located in the western side.2. Cladding junctions between different types of cladding and fl ashings to openings.3. Flashing detail between the negative eave and cladding.4. Ensuring that enough fall is provided from the farthest fi xture to the connection to the council sewer.
Why?:
1. I consider the foundation located in the western side of the site a risk because of the reduced stability of the ground due to the proximity of the slope to the foundation. If this is not correct severe settlement could occur and this would be a failure of B1 Structure.
2. I consider the cladding junctions between different types of claddings and fl ashings to openings a risk area as in the past these areas have been known to leak.
3. I consider the fl ashing detail between the negative eave and cladding a risk as this is a commonly forgotten detail and the area is prone to leaking in high winds.
4. I consider that the fall provided from the farthest fi xture to the connection to the council sewer is close to the minimum fall allowed (1:60) although it shows that it complies I would be noting this and asking the drainage inspector to pay particular attention on site.
Werethereanyalternativesolutionsusedinthisbuilding?Ifsopleasedescribeinyourownwordswhattheywere
andhowyouassessedthem:
Yes, as stated above the Linea® weatherboards were technically an alternative solution due to them being a fi bre cement product rather than a timber weatherboard. I justifi ed this by comparing them to the E2/AS1 solution for weatherboards that are similar in construction technique and dimension. I then justifi ed the durability of the product (particularly the fi bre cement aspect) throughthe product’s technical literature and fi bre cement’s historic use.
The consent also specifi es proprietary acrylic shower cubicles of a kind that are commonly installed in dwellings. These types of showers are alternative solutions as they do not strictly comply with E3/AS1. I have accepted these shower cubicles as they meet the relevant performance requirements of E3 Internal Moisture and also have appropriate historic performance.

Describeinyourownwordswhatyouconsiderisimportantinrelationtothefollowingrelevantaspectsofyourbuildinginspection:
1. Site/landthatbuildingisbeingbuiltoninrelationtotheinspection:
The site has a geotechnical report and specifi c requirements for certain areas of the site. The geotechnical report requires the western foundation to be deeper due to it being located in close proximity to a sloping bank and the reduced compaction of the ground in this area.
The site is close to a beach (seaspray zone) however the designer has provided evidence that the most western side of the site is actually just out side the sea spray zone (approximately 512 m). Therefore the required strength of exposed concrete, containing reinforcing steel is 20 mpa.
2. Structureanddurabilityinrelationtotheinspection:
Header blocks appeared to have been laid to the required fl oor level (from datum on plans). The builder on site confi rmed that he had set the level to the datum. I considered that no further fl oor level confi rmation was required as there is not a minimum fl oor level requirement for this site (or in fact the entire area). The standard requirement of E1/AS1 to be above the crown in the road has easily been achieved.
The fl oor slab is supported by compacted hardfi ll within the outer perimeter formed by the concrete blocks in max 150 mm layers. A vapour barrier consisting of 0.25 polythene with taped joints has been installed. A D12 perimeter bar has been tied into the starters around the perimeter of the slab. 665 mesh has been tied over the starters and packed up with plastic chairs. Laps for the D12 perimeter bar are a minimum of 32 x the diameter (most Laps 500-600 mm) and the mesh sheets have been lapped 1x square. Supplementary steel has been placed in internal corners where no shrinkage control joints have been placed.
In relation to durability aspects of this inspection, the steel placement meets the cover requirements of NZ S 3604:1999, the vapour barrier (0.25 polythene) has been placed on sand-blinding to prevent puncture. The concrete strength as discussed above will be 20 mpa.

3. Buildingenvelope(claddings)inrelationtotheinspection:
Claddings are yet to be installed; however, in relation to E1 as discussed above the fl oor level is above the crown of the road. I also discussed with the builder the requirement to lower the ground level to the south-eastern corner of the building where the original ground is almost level with the fl oor. The builder informed me that this will be taken care of before installing the cladding.
4. Firesafetyaspectsofthebuildinginrelationtotheinspection:
Not required to be assessed at this inspection.
5. Servicesandassociatedsystemsinrelationtotheinspection:
Plumbing services such as PVC waste pipes have been installed under the slab, the vapour barrier has either been taped to pipe extensions (for vanities or the like) or the slab has been boxed out to provide for an easy-clean waste (for showers). The waste pipes are sleeved through the concrete block foundation with denzo tape. In the north-eastern and south-eastern corners of the building two cells of the concrete blockwork (not containing reinforcing) have been fi lled up with sand to accommodate the installation of the main water supply and the main power and telephone supply.
6. Interiorfinishesinrelationtotheinspection:
Not required to be assessed during this inspection.
Describeinyourownwordstheareasofthebuildingyouconsiderariskinrelationtoyourinspection:
1. Ensuring the laps of steel are correct.2. Checking levels of the slab, especially if fl oor level restrictions exist.3. Making sure that the vapour barrier is installed correctly (as it’s very diffi cult to fi x after pouring).
Why?:
1. I consider that the laps in steel are important as it affects the structural integrity of the building and the signifi cance and probability of structural failure could increase.
2. Checking the levels of slabs is important because there could be signifi cant issues relating to fl ooding or HIRB (height in relation to boundary) issues that are affected if the fl oor level is not correct.
3. I consider the vapour barrier if not installed correctly could cause a major problem down the track (it would not become evident for a considerable time and would cause excessive moisture within the building) – a failure in this area would be very expensive to fi x.

Bill was observed to communicate well with internal and external staff and other Council clients. Bill ’s letters, RFIs and written communication were found to be of a very high standard. He was able to articulate his views clearly during our discussions and when sending out RFIs to applicants, he was found to not only explain why information was required, but consistently tied the request for information back to the relevant Building Code clause. Bill ’s communication skills were particularly evident in his candidate evidence forms for (processing and inspection) and within the associated consent correspondence.

Bill has also been supervised when undertaking inspections and peer-reviewed on many occasions. The outcome of the audits undertaken has not identifi ed any signifi cant technical or procedural issues (refer to inspection audit and processing peer review on Bill ’s personal training fi le). Bill has utilised the Councils’ continuous improvement system on two occasions this year where he has suggested process improvements.

brief description of building project being used for assessment:
TheBuilding
The building consists of a single storey portal-framed structure that is founded on a reinforced concrete foundation. Lower level external walls consist of pre-cast concrete panels to a height of 2.5 metres with long-run profi led metal sheet cladding fi xed to steel framing above. Offi ce areas are clad with fi bre cement-based sheet on a drained cavity. The roof is clad with long-run metal sheet. The roof design incorporates a small building-plant area, which will house the building’s air-conditioning system. Internally the building is divided into two large open retail spaces, a warehouse with goods stacked in proprietary racking systems (higher than 3 metres) and a drive-through timber yard area. Two small mezzanine areas are provided for staff offi ces, bathrooms, lunch and meeting rooms.

Building use: Commercial, crowd activity (CM)- crowd mediumOccupancy: 250 people Highest fi re hazard category (FHC): 4 Square metres: 950m2
Specifiedsystems
The applicant listed the following specifi ed systems on the form 2 building consent application:
• Automatic sprinkler system• Emergency warning system • Emergency lighting system• Mechanical ventilation (air-conditioning) • Backfl ow prevention• Means of escape (fi nal exits, fi re separations and signage)
describe in your own words what you consider is important in relation to the following aspects of your building project.
8.Site/landthatbuildingisbeingbuilton:
The site includes the following special features.
a. GIS mapping indicates the site is located within a specifi c design wind zone. The design engineer confi rmed this view by calculating the site’s wind speed to be 56 m/sec (designated specifi c engineered design (SED)). Structural design, loading calculations and material selection have all taken the sites relative wind loading into consideration.
b. The geotechnical report has identifi ed the site as generally having good ultimate soil bearing capacity; however a small portion of poor quality soil has been identifi ed at the southeastern end of the site. This localised area of poor ground requires specifi c strengthening attention to ensure the building platform can support the load-path from the super structure; consequently a condition has been added to the building consent under section 90 of the Building Act 2004 for third party verifi cation (PS4 monitoring) of this building work as we do not have the specifi c in-house competency to undertake such monitoring or soil testing. The design engineer responsible for observation work is well known to the BCA and is a practising CPEng.
c. The site is rural and is in zone 2 as defi ned in NZ S 3604:1999, indicating building elements are unlikely to be affected by accelerated atmospheric corrosion from wind blown salt laden air and the like.
d. The site has no easements, encumbrances, consent notices etc listed on the certifi cate of title. So no specifi c limitations/design modifi cations are necessary in this regard. Council records also indicate that the site does not have any land related issues such as hazards, contamination or heritage status etc.
e. A surveyor has been involved in defi ning the allotment’s boundaries, so boundary clearances etc should be relatively easy to establish on site.

9. Foundations:
Basis for design: AS/NZ S 1170:2002, B1/VM1 and B1/VM4
The building’s foundation is fully engineered and will be monitored at specifi ed times during construction (some specifi c soil testing is required to confi rm design assumptions made regarding poor soil quality at the southeastern end of the site).
The slabs’ DPM is well detailed on plan and within the specifi cation and meets the E2 performance requirements.
Perimeter pre-cast concrete panels are to be welded to base plates that are to be tied into the slab.
Other aspects of the foundation design were considered standard for this type of building work eg concrete strength, ground clearances, shrinkage control joist, steel size, steel cover and lap, DPM etc.
Some services are to be run within the slab, but this is covered in item 6 below.
10.Structureofthebuildingfromfoundation/slabup:
Basis for design: AS/NZ S 1170:2002, B1/VM1
The building’s structural frame/skeleton consists of steel portals and steel horizontal girts that are clad with long-run metal sheet cladding. Pre-cast panels extend 2.5 metres above fl oor level around the perimeter of the slab.
Plans and specifi cations for the project indicate the building structure (roof) is to support the weight of some large air-conditioning units. The air-conditioning units do not feature in any of the design engineer’s sketches and it is unclear if she is aware of the additional super-imposed load associated with these units (a phone call was made to the engineer to confi rm that the design had accounted for the additional loading imposed by these units). The engineer confi rms these units were not included on the plan version she was provided with. As a result the roof loading is recalculated and the units are moved to a more suitable location (amended plans were requested and provided). Fixing details were also requested for securing the units through the roof cladding in order to satisfy clause E2.
11.Buildingenvelope(claddings):
Basis for design: E2/VM1 and E2/AS1 modifi ed and used as an alternative solution for Building Code compliance.
The building is outside the scope and limitations of E2/AS1; however the designer has chosen to use some design principles and fi gures within the Acceptable Solution to prove compliance with clause E2. Given that the site is located in an SED wind zone and the designer has provided junction details that were unconventional it was decided to get the design peer-reviewed by an independent expert. The design was peer-reviewed by a recognised weathertightness expert who confi rms that the building meets clause E.2.3.2. The designer also provides in-service history of a similar building design that is subject to the equivalent wind pressure. A combination of in-service history and expert opinion confi rms the design meets clause E2 of the NZ BC on reasonable grounds.
12.Firesafety:
Basis for design: C/AS1
Active systems included: Basis for compliance
Automatic sprinkler system NZ S 4541:2007
Emergency warning system F7/AS1 NZ S 4512:2003
Emergency lighting system F6/AS1 AS/NZ S 2293:1995
Passive systems included:
Means of escape (fi nal exits, fi re separations and signage) C/AS1
The building is located at least 20 metres away from any boundaries and no other buildings are in close proximity, so spread of fi re beyond the building is unlikely.
The applicant provided a fi re report that used the Compliance Documents Acceptable Solution C/AS1 to illustrate compliance with the NZ BC. In line with our BCA’s policies and procedures our lead technical person for the C-Docs (John de-blaze) peer-reviewed the fi re report and associated plans. The internal review confi rmed my fi ndings and agreed the documents met the requirements of C/AS1 and the NZBC.

13.Services:
General All services penetrations were checked to have adequate protection (eg fi re collars, structural support, not compromising sound rated walls etc).
P&DDrainage and plumbing services for clauses (E1, G1, G2, G10, G12 and G13) were assessed by the BCA’s technical person (S Bend). A small issue was identifi ed regarding pipe falls for sanitary services in the slab (pipe falls within the slab were not adequately detailed on plan). S Bend contacted the designer and the appropriate falls were entered on the relevant drawings. Other P and D matters were found to comply with NZ BC.
Prescribed gas and electrical workCovered by an energy work certifi cate (providing a copy of these certifi cates is a condition of the building consent).
Specifi ed systemsIn accordance with section 7 of the Building Act the designer provided a list of the specifi ed systems to be installed in the building and the proposed procedures for inspection and maintenance of those systems. A schematic plan was also appended to this information to help with on site inspection and system identifi cation purposes.
Third-party commissioning certifi cates are required for the installation of the alarm and sprinkler systems (providing this verifi cation/certifi cation were made on condition of the issued building consent).
14.Interiorfinishes:
Spread of fi reFire resistance ratings and surface fi nishes were assessed and peer-reviewed as part of the fi re safety assessment. These items were found to meet the NZ BC.
Slip resistance The designer elected to use materials that met the slip resistance requirements detailed in D1/AS1 (eg, friction coeffi cient of not less than 0.4).
MoistureWet area fl oor and wall services were well detailed within the design documents and generally used E3/AS1 as means of compliance, albeit with a few minor alternative solutions (the design of a level access accessible shower was deemed beyond the scope of the acceptable solution as it used a sheet membrane on fl oor and wall surfaces; however, the design was found to be well detailed and deemed to meet the requirements of E3).
Describeinyourownwordstheareasofthebuildingthatyouconsiderarisk:
• Foundation – the geotechnical report identifi ed areas where poor soil quality was present.• Structural – building plant located on roof (air-conditioning units) • Building envelope – potential for water ingress and alternative solution offered as a means of compliance • Services – penetrations through fi re rated walls, specifi ed systems – correct design standards and inspection and maintenance
requirements. Pipe services in slab did identify falls/gradient.
Why?:
• Foundation – potential for localised building failure due to poor ground conditions. • Structural – potential for building failure due to an unsupported point-load that was not addressed during the design phase.• Building envelope alternative solution offered by applicant was viewed as potential area of weathertightness risk (peer-review requested
to support proposed design).• Services – penetrations through fi re walls create the potential to compromise fi re resistance.

Briefdescriptionofbuildingprojectbeingusedforassessment:
The building consists of a single-storey, portal-framed structure that is founded on a reinforced concrete foundation. Lower level external walls consist of pre-cast concrete panels to a height of 2.5 metres with long-run profi led metal sheet cladding fi xed to steel framing above. Offi ce areas are clad with fi bre cement-based sheet on a drained cavity. The roof is clad with long-run metal sheet. The roof design incorporates a small building-plant area, which will house the building’s air-conditioning system. Internally the building is divided into two large open retail spaces, a warehouse with goods stacked in proprietary racking systems (higher than 3 metres) and a drive-through timber yard area. Two small mezzanine areas are provided for staff offi ces, bathrooms, lunch and meeting rooms.

Briefdescriptionofinspectionbeingundertakenforassessment:
Final inspection for commercial level 2 type building work.
Objective: ensuring the building work has been carried out in accordance with building consent – plans and specifi cations and any amendments, minor variations undertaken during the project and meets the NZ BC requirements.
A review of the consent fi le was undertaken before visiting the site to familiarise myself with the status of the project and identify if there were any outstanding compliance matters.
The project manager responsible for managing the development asked that he be present during the inspection. This was agreed to as it was felt it would be benefi cial should any queries arise about technical matters.
A separate fi nal inspection covering P&D compliance is to be undertaken.

7. Site/landthatbuildingisbeingbuiltoninrelationtotheinspection:
• As the site is located in a specifi c design wind zone (subject to higher than normal wind pressures) and has some unconventional cladding design details have been used. I will place particular emphasis on inspecting these aspects as it is important to ensure the building’s external envelope has been completed in accordance with plans and specifi cations.
• The site’s geotechnical report identifi ed specifi c requirements for certain areas of the site. As a consequence the project manager has agreed to provide copies of the engineer’s inspection notes and a (PS4) to confi rm the building work undertaken meets the Building Code (means of compliance: Verifi cation Methods cited in the Compliance Document for B1).

8. Structureanddurabilityinrelationtotheinspection:
• As noted above the engineer’s inspection notes and (PS4) are to be provided during the inspection to confi rm compliance in relation to structural matters conditioned on the building consent.
• A visual inspection of completed work was undertaken to ensure visible fi xings, ties, bracing etc are in place and are compliant. This was not done to redress items already inspected during preline/postline inspections. It was simply undertaken as general observation of the building’s overall structural compliance.
• I inspected the building for any evidence of structural movement, settlement, subsidence, warping, compression etc that would raise concern and may require additional investigation. No such issues were evident.
• A visual inspection of external/internal materials and coatings was undertaken to ensure these items met the plans and specifi cations and the Building Code, in particular clauses B1, E2 and B2.
9. Buildingenvelope(claddings)inrelationtotheinspection:
• I ensured the external envelope had been completed in accordance with building consent (plans and specs). As the building work includes alternative solutions used as a means of compliance, more emphasis was placed on the inspection of unconventional details, such as junction fl ashings between different cladding types. As an additional precaution, internal moisture level readings were taken on internal lined wall surfaces to provide additional support for the end compliance decision.
• I visually checked exposed fl ashings, membranes, cavity vents and drainage and kept an eye out for any un-consented attachments to the building envelope.
10.Firesafetyaspectsofthebuildinginrelationtotheinspection:
• A full walk-through inspection was undertaken to ensure the nominated means of escape was compliant and penetrations to fi re walls were sealed and made good.
• Life-safety systems (specifi ed systems) were confi rmed to be operational. Third-party verifi cation/certifi cation and commissioning information was provided to confi rm the fi re alarm and sprinkler had been installed in accordance with specifi ed NZ Standards (eg, NZ S 4512:2003 for the alarm system).
11.Servicesandassociatedsystemsinrelationtotheinspection:
• P&D inspection is to be undertaken by a BCO with the appropriate P&D competencies (not part of this inspection).• The fi nal inspection revealed that the following specifi ed systems had not been identifi ed during the processing stage of the building
consent. The owner had failed to identify the following specifi ed systems within their application for building consent – smoke control system for removing smoke and a CO detection device for early warning of gas leakage. Both specifi ed systems were located within the car park area of the building (refer to attached photos 1 and 2 for details of these specifi ed systems). Further information was requested regarding the installation, performance, inspection and procedural requirements of these specifi ed systems. Note: The fi nal inspection was failed as a result of this fi nding.
• The project manager was informed of the areas of non-compliance (non-consented building work) and was provided with an inspection report that outlined what was required to resolve these matters (amended plans and specifi cations, and performance, maintenance and reporting procedures for each specifi ed system). The project manager acknowledged the importance of getting these matters resolved and forwarded the information required, which in turn was added to the compliance schedule.
12.Interiorfinishesinrelationtotheinspection:
• Inspection of these elements was undertaken during the inspection of means of escape (in item 4). This included a visual check of fl oor, wall and ceiling fi nishes and fi xtures and fi ttings to ensure they comply with the plans and in particular the fi re report.

Describeinyourownwordstheareasofthebuildingwhatyouconsiderariskareainrelationtoyourinspection:
• Foundation – the geotechnical report identifi ed areas where poor soil quality where present (potential risk of structural failure).• Structural – building plant located on roof (air-condition units creating a superimposed /point-load.) • Building envelope – potential for water ingress as an alternative solution had been offered as a means of compliance• Services – penetrations through fi re rated walls, specifi ed systems- correct design standards and inspection and maintenance
requirements. Pipe services in slab did identify fall/pipe gradients. • Specifi ed systems installed, but not identifi ed within the consented documents. Amended plans and specifi cations required prior
to issuing the CCC.
Why?:
• Foundation – potential for localised building failure due to poor ground conditions. • Structural – super-imposed load to roof could create issues if not correctly designed and/or installed.• Building envelope – the alternative solution offered by the applicant was viewed as potential area of weathertightness risk.
Unconventional design means checking of building envelope is very thorough. • Services – penetrations through fi re walls create the potential to compromise fi re resistance. • Specifi ed systems that are not picked up during a building consent will not end up on the buildings compliance schedule
and will consequently not get inspected and maintained over the life of the building.
