Productivity Simulation During the Planning Phase of the Glencoe Tunnel in Calgary, Canada: A Case Study

Abstract

This paper discusses the Glencoe Storm Sewer Upgrade Project in Calgary, Alberta. The proposed tunnel is 2920mm in diameter, stretching along 27th Ave SW from 15th St SW to 20th St SW with a total length of 935m. Its depth varies from 16m at the working shaft to 42m at the retrieval shaft. The tunnel will reduce surface flooding by providing temporary storage of stormwater runoff during major storm events. The focus of this paper is project planning. The planning phase includes scope definition, contract setup, cost estimate, team assembly, equipment and material procurements, risk analysis, constructability review, geotechnical investigation, Safety and ECO Plan development, and scheduling and productivity simulations. The challenges presented in this project are the unfamiliarity with the local conditions and the uncertainty of the projected productivity and completion date of the project. Those issues were modeled and mitigation strategies were established using simulation technologies.

Planning of Tunneling Projects Using Computer Simulation and Fuzzy Decision Making

“…Several efforts have been conducted in planning of construction projects using computer simulation. These studies include concrete operations (Hassan, Gruber 2008), bridge decks construction (Marzouk et al 2006(Marzouk et al , 2008a, earthmoving operations (Marzouk 2002), and tunnel constructions (Al-Battaineh et al 2006;Tanaka 1993). Limited studies have been conducted for simulating the construction of cut-and-cover tunnels with different supporting techniques.…”

Bauzeitenvorhersage von Injektionen im Tunnelbau

“…So simuliert sich wiederholende Prozesse bei Arbeiten im maschinellen Tunnelbau. verwendet eine vor allem im akademischen Umfeld genutzte Simulationssoftware zur Bauzeitvorhersage und Risikoanalyse während der Planungsphase des kanadischen Glencoe Tunnels. nutzen die gleiche Software zur Bauzeitoptimierung des North Edmonton Sanitary Tunnel (NEST) in Kanada.…”

Ontological Models for Simulation of Building Construction Processes

“…The first simulation methodologies in construction began in the 70's with Halpin [15], which evolved to be applied in several projects in the construction industry [16]. It has been used in: tunnel construction [17,18]; operation of tower cranes [4]; earthmoving projects [19,20]; high-rise buildings projects [21]; construction of pavements, and roads [5,22,23].…”
