CASE STUDY – 3 NEWMARKET OFFICES

Aamsko, in partnership with Zenith Facilities Services, was commissioned to assess and provide remedial solutions for the weathertightness failures concerning three buildings in Newmarket, to provide the client with invaluable insight into the health and longevity of these three buildings, to allow an informed strategic plan for the finding, investment and renovation renovations. The buildings have a unique building envelope design utilising precast and in-situ concrete, concrete masonry blocks together with glazed aluminum curtain wall systems. Zenith Facilities Services conducted forensic water and moisture ingress documentation under the guidelines of ASTM E 2128 to obtain a forensic understanding of the building’s condition so that a suitable remedial maintenance scope and specifications can be attained. The data was gathered via internal and external visual inspections, together with moderately invasive internal inspections and water ingress testing, involving the roof, walls and joinery to identify vulnerabilities and point of failure for all three buildings. The results highlighted several weathertightness concerns of similar nature contributing to the water and moisture ingress presenting at the buildings. Based on our inspections and information available from the property file, Aamsko created detailed drawings to clearly depict the weathertightness failures and points of water/moisture ingress into the buildings. Concrete Cantilever Balconies with Concrete Masonry Parapet The balconies are flooding due to lack of correct fall and drainage, resulting in water entering the building due to the lack of an adequate upstand for the sliding door. Water seepage from the cold join of the balcony deck and the parapet wall due to the decks flood can be visually observed. Due to prolonged and consistent moist condition of the masonry block parapet and lack of flashings, cracks are presenting because of over carbonation, and the steel balustrade rail is rusted beyond safe use. Insipient anode syndrome has begun to present where concrete has commenced to spall around the mounting of rusted parapet rails. Internal Gutter System – Ingress at Concrete Masonry Wall and Glazed Curtain Wall The internal gutters of the buildings are constructed of plywood substrate, with metal box guttering and waterproof membrane that has exceeded its useful serviceable life. AAMA 511 water ingress testing of the internal gutter systems resulted in water and moisture ingress into the internal space at several locations in the three buildings is a result of the internal gutter system, due to the lack of gutter capacity, fall, and poor design/workmanship. The internal gutter was determined to be the cause of ingress through AAMA 511 water ingress testing and the monitoring of moisture levels as the tests were conducted at the masonry black walls. The inadequate fall of the internal gutter system is causing to water pooling for long periods of time. This results to premature degradation of waterproofing and the timber substrate, leading to overflow into interior of the building and a prolonger moisture seepage into concrete black walls. Protruding Fin Detail The façade design of two of the buildings has radial protruding concrete masonry fin detail, the defects of which observed to be worse at Level 2 and the site of the central fin below the internal gutter end. Significant moisture ingress damage in the form of efflorescence and loss of adhesion to paint where the fin protrudes the interior space. This moisture damage continued to the exterior of the fin, tracking along the masonry block joints. Water-marked timber framing and plywood was present around the internal gutter, with a gap in the gutter visible from the interior. On the roof, the flashing wrapping the concrete masonry fin has wet marks, with water retained under the cap flashings at fixing points. AAMA 511 water ingress testing was conducted at the internal gutter, and water ingress was observed, with the amount of water increasing as the gutter exceeded its capacity and overflowed. Water leaked through a gap in the gutter system, splashing down onto the loadbearing pillar before spilling onto the floor. Water ingress into the internal space is due to lack of gutter capacity, fall, and poor design/workmanship. Internal Intertenancy Party Wall The reinforced concrete masonry intertenancy wall on the ground floor at one of the buildings shows signs of moisture ingress and damp rising on both sides of the wall. The defects presented as loss of paint cohesion, concentrated at the base of the wall, suggesting it originates from the ground or carpark below. The carpark concrete masonry retaining wall directly below has severe muddy water marks and mould growth.

BUILDING COMPLIANCE

New Zealand’s building legislation drives the industry, providing framework for all building work carried out in our country. It sets building performance standards to achieve the purposes of the Building Act 2004. The Building Act 2004 governs the building sector and sets out the rules for construction, alteration, demolition, removal and maintenance of new and existing buildings in New Zealand. Within the scope of the Building Act are: Under the Building Act, all building work must comply with the Building Code, even if the work does not require a building consent. This ensures buildings are safe, healthy and durable for everyone who may use them. The Building Act and Building Code are mandatory legislation, and complying with them is required by law. Below the Building Code are a series of documents providing compliance pathways, such as verification methods, acceptable solutions and alternative solutions, are non-mandatory methods on how to be complaint with the Building Code. The Building Code is found in Schedule 1 of the Building Regulations 1992. It sets out the minimum standards that buildings must meet. It states how a building must perform in its intended use, rather than describing how the building must be designed and constructed. It is divided into 8 classifications, identified by letters A – H, and sets clear expectations of the standards building must meet. It is a performance-based code, allowing flexibility in the design and construction of the buildings. The 41 clauses within the Building Code cover: The requirements of the Building Code clauses are set out into three parts: The process of complying with the Building Code requires that the plans and specifications for any building work, including new buildings, alterations, additions or demolition, are assessed by a Building Consent Authority (BCAs). Generally, this will be the local Council, who will ensure that the proposed work will comply with the Building Code requirements. When the BCA is satisfied that the proposed work will comply, a Building Consent will be issued that work can proceed, but it must be carried out in accordance with the consented documentation. Once the building work is completed, the BCA will issue a Certificate of Code Compliance (CCC). A Code Compliance Certificate is a formal statement of approval from the council that the construction is according to the Building Consent that was issued and confirms the requirements of the Building Code have been met. Alternatively, if the building is exempt from the Building Consent process, a Certificate of Acceptance (CoA) can be obtained if: A Certificate of Acceptance provides a limited assurance that a BCA is satisfied, on reasonable ground, that unconsented building work complete with current building code. A CoA can be applied for all or part of a building, but evidence must be provided so the BCA can assess whether the work complied with the Building Act. If compliance with the Building Code cannot be demonstrated, the council may refuse to issue CoA and building work may need to be removed. All work needs to comply with the Building Act, and it is an offence to carry out building work for which a building consent is required.
