In recent years, Trenchless Technology (TT) methods have assumed an essential role in minimizing disruptionsto traffic, business and other activities during the construction of transmission pipelines. Due to two majorfactors, which are cost and risk, trenchless methods are only considered in brown field wherever there are noother feasible options. In residential land development, open cut method is used for the construction of landinfrastructure such as water supply, sewers, power grids and telecommunications. However, in cold region likeAlberta, the construction season for open cut is only 6-7 months each year and land developers generally do notinstall shallow utilities during the winter season. The proposed research will investigate the feasibility of usingTT in residential land development and compare TT and conventional open cut methods in terms of costs,schedule and Greenhouse Gas (GHG) emissions. Landmark, the industrial partner of the project, will providethe opportunity of a small-scale field trial in a multi-family residential project. The research team willinvestigate applicability of different TT methods in residential land development, analyze the risks associatedwith each TT method, quantify GHG emissions in the construction processes, compare cost and schedule, andstudy the social impacts of TT and conventional open-cut method. Using TT in utility pipeline installation hasthe potential to extend the construction season of land infrastructure in cold regions, decrease the project costand reduce the environment impacts.

近年来，非开挖技术(TT)在最大限度地减少对交通、商业和其他活动的干扰方面发挥了重要作用。由于成本和风险两个主要因素，非开挖方法只有在没有其他可行方案的棕地才被考虑。在住宅用地开发中，供水、下水道、电网、电信等土地基础设施建设采用明挖法。然而，在艾伯塔省这样寒冷的地区，露天采矿的施工季节每年只有6-7个月，而且土地开发商通常不会在冬季安装浅层设施。这项拟议的研究将调查在住宅用地开发中使用TT的可行性，并从成本、进度和温室气体排放方面比较TT和传统的露天开采方法。该项目的工业合作伙伴Landmark将提供在多户住宅项目中进行小规模实地试验的机会。研究小组将调查不同TT方法在住宅用地开发中的适用性，分析与每种TT方法相关的风险，量化施工过程中的温室气体排放，比较成本和进度，并研究TT和传统露天开采方法的社会影响。在公用事业管道安装中采用TT技术，有可能延长寒冷地区土地基础设施的施工季节，降低工程造价，减少对环境的影响。
