CLIENT: HASTINGS BOYS HIGH SCHOOL
TECHNOLOGY BLOCK REFURBISHMENT
Architect Les Clapcott of Clapcott Consultancy after receiving written submissions of interest from various construction companies, formulated a short list of competent companies who were invited to submit their tenders for the Refurbishment of the Hastings Boys High School Technology block.
The tender was in its self a challenge with the comprehensive nature of the alterations and high standard of finishes. The was a wide range of trades required by Mr. Clapcott to access the unknown nature of an old building. The tender was required to be broken down into a series of individually priced options for the consideration by the school and the architect, to assess the final scope of the project within budgetary constraints and funding.
Pro-Structure were awarded the contract including all the various options submitted as part of the tender. In November 2012 Stage One began with the Graphics, Automotive and Metalwork Shop, plus giving a breath of new life to existing toilets and to a create Teachers Resource Area. This was by far the largest and most intensive section of the project involving a wide range of trades and skills, and most of the work was centred in the original old wooden sections of the block.
Stage Two involved the remaining portion of the block housing of the woodwork Classroom and Machine Shops including a new dust extraction system, and was centred in the more modern concrete section of the block.
The options added to the contract were the provision of a new architectural canopy leading to the Wood Work areas, plus another canopy sheltering the access to the Metalwork Workshop and the Automotive workshop. All old double hung timber windows to the Metalwork, Automotive and Graphic rooms were replaced with new powder coated aluminium sashes housed into the existing frames and facings.
Ancillary to this all box gutters to the concrete areas of the block were leaking and downpipes blocked and not functioning. The existing gutters were relined, and in some cases rebuilt to good falls and modified rainwater disposal piping. The old wooden building suffered from a lack of subfloor ventilation, ducting was installed and existing vents were cleared to vastly improve the cross ventilation under the building.
There were many challenges with this project due to the nature of the existing structures. Various repairs and replacement of sections of decay and moisture damage was needed. Pipes, wires, gas lines and other services calling for site detailing by Pro-Structure staff in consultation with the architect were needed to achieve the finished result and function that the school required without incurring excessive variations in cost.
With a solid team of tradesmen and detailed planning, Pro-Structure was able to complete the project on time. Despite the challenges and additional work, an excellent result for the school was achieved. Whilst there were variations due to the nature of the build, we were proud to hand over to the Hastings Boys High School the results of our labours, knowing that we had achieved to a high standard what the Architect and the School had wanted from this refurbishment.
Early on in the build, Pro-Structure was advised that the block would require Earthquake Strengthening to bring it up to a standard required as a result of the Christchurch Earthquakes. Pro-Structure in conjunction with the architect and engineer worked together to find a solution that did not compromise the end appearance and achieved the desired engineering standard. This work however, did interfere with the programme of work scheduled, but with the “let’s get it done” attitude of the Pro-Structure staff was completed with minimal effect on the time lines that were set.
Design and Build is a strength that Pro-Structure have and they were used to assist the architect in the design of an automatic detection and disposal system for the Automotive Workshop. Our administration team worked with electricians, mechanical engineers and sheet metal workers to utilise and modify two existing extraction flues. These were linked to an electronic carbon monoxide and carbon dioxide sensor, which would activate one of the extraction flue to automatically activate on the detection of the CO & CO2 gases. The other is a manual system linked to flexible hoses for fitting of motor exhausts for extraction whilst motors are running. The system is simple to use and as it has transpired with the use of some existing fans and flue a cost effective solution for the school to eliminate a serious hazard.
