Fugro帮助IWM Duxford上方和地下

With almost a century of development, IWM Duxford (a 60-hectare aviation museum with 200 aircrafts) has a vast network of buried pipes, cables and other services, many disused and unrecorded, running beneath the ground.

The buildings team decided to commission a utilities survey, using the latest non-intrusive ground investigation techniques to map networks below with minimal disruption to museum operations above. This underground reconnaissance is now helping to inform the planning and risk management of ongoing building work and site development.

Following competitive tender, the contract was awarded to Fugro, a global leader in geoscientific surveys and data to support asset integrity from pre-construction through service life.

调查范围包括电缆（高电压），气体管道，电信服务，国内和消防栓水管，燃料和油系。

With substantial experience in utilities investigations, from highways and airports to city centre and industrial developments, Fugro recommended the use of electromagnetic cable location (ECL) together with ground penetrating radar (GPR) surveys. These survey techniques use electromagnetic impulses sent from the surface to locate buried pipes, cables and other objects at depths typically to 1.5 metres, without the need to dig, drill or disturb the ground.

作为非破坏性，高度移动和谨慎的方法，这些可以最大限度地减少对历史环境和现场运营的影响，最重要的是博物馆访客和机场事件。组合，他们还提供了有效映射的机会，依靠Fugro的解释专业知识，而无需诉诸侵入性的调查 - 在繁忙和历史遗迹的尽可能避免。

Site Meeting

Fugro undertook an extensive site walk in order to plan the survey programme to accommodate a full range of site access and health and safety considerations.

Fugro Project Manager Charlie Baker表示：“彻底的网站访问对于任何调查的顺利运行至关重要，特别是在IWM Duxford这样的大量设施，这一年都可以向公众开放。早期承包商参与提供了充分了解客户需求和期望的理想机会，并讨论所提出的技术的能力和限制以及数据的准确性。“

他继续说：“需要有效计划的调查，以符合客户的预算和计划分配，同时适应挑战的访问限制。”

Fugro检查了过去公用事业工作的可用文件，许多早期记录在羊皮纸甚至布料上存活。这些仍然有助于形成现有服务的可能分配的图片，并有助于将现代调查结果相关联。

Avoiding disruption to site traffic and visitors was a priority. By undertaking some elements of the survey ‘out of hours’, Fugro managed to schedule all the work with no closures to car parks or site roads.

Liaising closely with the museum, Fugro’s site team undertook risk assessments and health and safety measures while also observing site security, to ensure the survey work posed no hazard to the public or site personnel.

移动技巧

Fugro geophysicists completed the surveys within 26 day shifts, covering 10 hectares of the North side of the museum site and 48 hectares of the South side. Most of the work was undertaken within land-side areas, the mobile techniques adapting readily between varying ground conditions such as grass, concrete hardstanding, roads and footways.

Fugro确定了机场控制塔周围的埋藏服务数量高于预期的埋地服务，许多不明显地从腔室检查中明显，但通过地球物理技术拾取。这些遗物和未知的服务不仅难以找到，而且还呈现了未来建筑工作的最大潜在风险。

识别和绘制埋藏服务对于规划新的建筑或涉及地面的维护至关重要。通过准确和地理位置的地图地图，设施维护团队可以确保员工或承包商进行挖掘，了解埋藏危险，以尽量减少击中水管，燃料管线或电力电缆的风险。

A limited number of airside surveys were completed which are already being put to good use. They included the identification of utilities entering the construction zone for the Aircraft Restoration Company’s new Stephenson Hangar, built to accommodate maintenance work carried out on the Battle of Britain Memorial Flight Avro Lancaster.

In line with the client’s requirement, the full results of the survey were presented using CAD, with each service colour-coded for ease of reference.

Artefacts

As a listed heritage site, IWM Duxford incorporates historically significant hangars and buildings, assets as integral to the museum’s legacy as the artefacts they protect.

对于建筑物团队来说，关于地下基础设施的准确数据与CCTV的资产弹性的投资相同。通过清晰的埋地公用事业的图片，可以帮助通知基础干预措施，更好地能够管理可能导致洪水，火灾或爆炸的管道和电缆损坏的风险。这是保障人员，资产的运作连续性以及不可替代价值的军事航空遗产的重大保证。
