forward shield to outer telescopic shield, outer to inner telescopic, inner telescopic to gripper shield, and so on for a double shield machine.\u00a0\u00a0 So the part fit-up is checked but the entire machine is not put together in the factory.<\/p>\n<div id=\"attachment_3023\" style=\"width: 645px\" class=\"wp-caption aligncenter\"><a href=\"\/wp-content\/uploads\/2012\/01\/OFTA_component_fitup_blog_pic4.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3023\" class=\"size-full wp-image-3023\" title=\"OFTA_component_fitup_blog_pic4\" src=\"\/wp-content\/uploads\/2012\/01\/OFTA_component_fitup_blog_pic4.jpg\" alt=\"Ensuring fit up of components\" width=\"635\" height=\"400\" \/><\/a><p id=\"caption-attachment-3023\" class=\"wp-caption-text\">Major components are checked in the factory to ensure fit up.<\/p><\/div>\n<p><em><em>2.\u00a0 Modern measurement devices<\/em>:<\/em>\u00a0 In those cases where it is not possible to pre-fit two pieces in the factory, we can use modern Coordinate Measuring Machines (CMMs) or \u201cLaser Trackers\u201d to take precise measurements of both pieces to insure fit up when they meet in the field.<\/p>\n<div id=\"attachment_3024\" style=\"width: 645px\" class=\"wp-caption aligncenter\"><a href=\"\/wp-content\/uploads\/2012\/01\/OFTA_lasertracker_blog_pic2.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3024\" class=\"size-full wp-image-3024\" title=\"OFTA_lasertracker_blog_pic2\" src=\"\/wp-content\/uploads\/2012\/01\/OFTA_lasertracker_blog_pic2.jpg\" alt=\"Using a Coordinate Measuring Machine\" width=\"635\" height=\"400\" \/><\/a><p id=\"caption-attachment-3024\" class=\"wp-caption-text\">A Robbins employee uses a CMM device in the Ohio manufacturing facility.<\/p><\/div>\n<p><em><em>3.\u00a0 In-field repairs:\u00a0<\/em><\/em> When an offshore oil rig has a component failure do they disassemble it and take it to the mainland for repairs?\u00a0 When repairs are required on hydroelectric turbines and generators, do they always take the big parts to a machine shop to repair?\u00a0 No, they do not.\u00a0 Many repairs of large scale equipment are made in situ, wherever the plant is located.\u00a0 If it is discovered at the job site that a component has been mis-machined \/ manufactured it is most likely a minor error (remember the CMM measurements and component fit-ups in factory partial assembly) and repair can be effected on the piece in place at the job site.\u00a0 In Robbins experience, this has always been the case and such repairs have been carried out when discovered on site and without impact to final startup schedule.<\/p>\n<h4><\/h4>\n<p>&nbsp;<\/p>\n<h4>Myth No. 2 \u2013 The labor cost on an underground job site is far higher than labor cost in a factory.\u00a0 It will cost far more money and time to assemble the machine on site for the first time.<\/h4>\n<p>&nbsp;<\/p>\n<p>OFTA Myth No. 2 leads to a wrong conclusion regarding cost, and fails to examine fully the potential benefits.<\/p>\n<p><em><em>1.\u00a0 Cost<\/em>:<\/em> This above statement is generally true; however, it does not necessarily follow from this statement that money will be saved by having a factory assembly plus a job site assembly.\u00a0 Robbins history with in-factory and OFTA assembly reveals the following:<\/p>\n<p><span style=\"text-decoration: underline;\">Traditional Factory Assembly<\/span><\/p>\n<ul>\n<li>Full factory assembly hours:\u00a0 X hours<\/li>\n<li>On-site assembly of a fully factory assembled machine: 0.5X hours<\/li>\n<\/ul>\n<p><span style=\"text-decoration: underline;\">OFTA Method<\/span><\/p>\n<ul>\n<li>Partial factory assembly for OFTA delivery: 0.5X hours<\/li>\n<li>OFTA site assembly of a partial factory assembled machine: 0.7X hours<\/li>\n<\/ul>\n<p>Where the value of X is dependent upon the size and type of TBM as well as the complexity of the backup system.<\/p>\n<p>If we assume that the cost of labor on the job site is twice the cost in the factory, then we can use $100\/ hour for the job site and $50 \/ hour for the factory.\u00a0 The total cost for the two methods is then:<\/p>\n<ul>\n<li>Traditional method cost = X hours ($50\/hour) + 0.5X hours ($100\/hour) = $100X<\/li>\n<li>OFTA method cost = 0.5X hours ($50\/hour) + 0.7X hours ($100\/hour) = $95X<\/li>\n<\/ul>\n<p>In short, the total costs are nearly the same, or perhaps with some savings in favor of the OFTA method.<\/p>\n<p><em><em>2.\u00a0 Schedule<\/em>:<\/em> Another flaw with Myth No. 2 is that it does not consider a large potential benefit: the savings in schedule possible with the OFTA method.\u00a0 By not completely assembling the TBM in the factory, it is possible to deliver a working TBM at the job site one to two and a half months earlier than with a traditional full-factory assembly and delivery.\u00a0 This is a significant savings for most projects, when the site assembly can be done at this early stage.<\/p>\n<div id=\"attachment_3026\" style=\"width: 645px\" class=\"wp-caption aligncenter\"><a href=\"\/wp-content\/uploads\/2012\/01\/MB_316_OFTA_blog_pic1.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3026\" class=\"size-full wp-image-3026\" title=\"MB_316_OFTA_blog_pic1\" src=\"\/wp-content\/uploads\/2012\/01\/MB_316_OFTA_blog_pic1.jpg\" alt=\"Niagara cutterhead assembly\" width=\"635\" height=\"400\" \/><\/a><p id=\"caption-attachment-3026\" class=\"wp-caption-text\">OFTA for the 14.4 m diameter Niagara TBM was completed in four months, saving an estimated four to five months on the delivery schedule.<\/p><\/div>\n<p><em><em>3.\u00a0 Training of site personnel<\/em>:\u00a0<\/em> Another potential benefit that Myth No. 2 does not address is that of training.\u00a0 The contractor\u2019s site personnel who are involved with OFTA assembly and testing get far more training due to the additional hours spent on the assembly and testing, and the larger Robbins crew present to assist and advise.\u00a0 Robbins&#8217; experience indicates that contractors who opt for OFTA deliveries are frequently capable of taking over the full operation and maintenance of their new TBM much quicker than contractors who opt for a traditional delivery.\u00a0\u00a0 This is due to the much deeper knowledge the contractor\u2019s personnel gain during the OFTA assembly and testing.<\/p>\n<div id=\"attachment_3025\" style=\"width: 645px\" class=\"wp-caption aligncenter\"><a href=\"\/wp-content\/uploads\/2012\/01\/DS_AMR_OFTA_blog_pic3.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3025\" class=\"size-full wp-image-3025\" title=\"DS_AMR_OFTA_blog_pic3\" src=\"\/wp-content\/uploads\/2012\/01\/DS_AMR_OFTA_blog_pic3.jpg\" alt=\"OFTA in India\" width=\"635\" height=\"400\" \/><\/a><p id=\"caption-attachment-3025\" class=\"wp-caption-text\">Site personnel take part in the assembly of a Double Shield TBM in India.<\/p><\/div>\n<p>In summary, the question to be asked when making the decision to use OFTA or go for a traditional factory assembly is: What are the potential risks and what are the potential rewards?\u00a0 One must examine all potentials of the OFTA scenario, pros and cons, to come to the correct solution.\u00a0\u00a0 I\u2019m not claiming that an OFTA scenario is correct for every project.\u00a0\u00a0 For example, if the start of boring of the tunnel is not on the critical path for the project and the TBM is a smaller diameter unit, it might be advisable to allow a full factory assembly. That way, when the job site is finally ready for the machine, it can be assembled a bit quicker on site.\u00a0 Again, if the start of boring is not on the critical path and the labor cost difference between job site and factory is larger (e.g., job site is in Finland, TBM factory is in China), then it could be that a full factory assembly can be justified on a cost only basis.\u00a0 However, in nearly every case when the start of boring the tunnel is on the critical path, then the faster delivery possible by OFTA is clearly favorable.<\/p>\n<p>The biggest impediment to more widespread use of OFTA is limited thinking: looking at the potential risks without looking at the potential rewards.\u00a0 Tunneling itself is fraught with risk, yet contractors take on jobs everyday due to the potential rewards.\u00a0 OFTA is deserving of a similar analysis.<\/p>\n<p>&nbsp;<\/p>\n<h4>About the Author<\/h4>\n<p><a href=\"\/wp-content\/uploads\/2012\/01\/Joe-Roby-headshot.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-thumbnail wp-image-3028\" title=\"Joe Roby headshot\" src=\"\/wp-content\/uploads\/2012\/01\/Joe-Roby-headshot-150x150.jpg\" alt=\"Joe Roby\" width=\"150\" height=\"150\" \/><\/a>Joe Roby (B.S., Mechanical Engineering, University of Washington) has worked in the tunneling industry for more than 20 years.
