Timber Frame Assessments<\/h1>\n

[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n

Timber frame assessments and decay identification are required during remediation and recladding projects, to ensure the damaged timber is removed and the remaining framing is fit for purpose.<\/h3>\n

Identification of decayed timber<\/h3>\n

We are qualified and experienced in the identification of decayed timber requiring replacement during the remediation of leaky buildings. Damaged timber is spray marked and scheduled for replacement. We are pragmatic with our remediation and do not \u2018over remediate\u2019 the structural timber frame. <\/span><\/p>\n

We use a variety of techniques to assess the condition of timber framing in defective buildings, including visual inspection based on our extensive experience in building remediation, moisture testing, brashness testing, and laboratory analysis.<\/p>\n

It is essential that the decayed timber is successfully removed from a leaky building. Due to the high levels of humidity in areas such as Auckland, Northland and the Bay of Plenty, the equilibrium moisture content of the timber due to humid atmospheric conditions can be high enough to continue to propagate decay fungi.[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]<\/p>\n

Remedial monitoring<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

We monitor the remedial construction process to ensure that the timber scheduled for replacement is replaced and that the existing timber framing is treated with a preservative treatment to demonstrate compliance with the NZ building code clause B2 Durability.<\/span>[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]<\/p>\n

Quality Assurance – Timber sampling and laboratory analysis<\/h3>\n

\"timber<\/p>\n

We extract a limited number of timber samples from the existing timber framing scheduled to remain in position in the building for laboratory analysis. The timber samples are extracted from framing adjacent to areas of timber that have been damaged due to weathertightness failure.<\/p>\n

Laboratory analysis is undertaken to confirm the existing levels of timber treatment (if any) and the fitness for purpose of the timber to remain in the building. This gives the Owners, Contractor, Consultant and Auckland Council surety that the framing left in situ is fit for purpose, i.e. free from decay and complies with the requirements of clause B2 Durability of the NZBC.[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]<\/p>\n

Photographic remediation reports<\/h3>\n

We provide a photographic remediation report as a record of the timber framing remedial process, which includes our durability statement.[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]<\/p>\n

Durability statement<\/h3>\n

We provide a durability statement (producer statement) for the timber frame of the building, stating that the framing has been remediated in accordance with the requirements of the building consent and that the framing complies with the requirements of clause B2 Durability of the NZBC.<\/p>\n

Auckland Council accepts our photographic reports and producer statements.<\/span>[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text css=”.vc_custom_1566765327040{padding-top: 3% !important;padding-right: 5% !important;padding-bottom: 7% !important;padding-left: 5% !important;background-color: #f2f2f2 !important;border-radius: 10px !important;}” el_class=”highlight-box3″]<\/p>\n

Timber frame assessment – not as simple as it looks<\/h3>\n

Our specific training and years of experience in assessing timber frames for decay has taught us that it is not as simple as it seems. Extensive laboratory analysis of timber samples for litigation claims has taught us, for example, that brown rot can remove the bulk of the structural integrity of the timber before it is visible to the human eye.<\/p>\n

In other words, the timber looks clean and sound but contains advanced decay. Similarly, timber framing that is blackened with mould is not necessarily decayed and may not require replacement. This is why you should engage an expert to assess the timber frame for your remedial project.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” css=”.vc_custom_1564522425952{background-color: #ffffff !important;}” z_index=””][vc_column]
