Nicoll Highway collapse

 * Nominator(s): ZKang123 (talk) 04:45, 25 January 2024 (UTC)

The Nicoll Highway collapse was a major construction accident in Singapore which killed four people, and it subsequently led to a revision of safety construction practices in the country. This article has expanded from just a start-class with more information regarding the circumstances of the collapse, the rescue efforts and the subsequent inquiry into the collapse. Despite its significance, there remains few international commentary on the incident (not even a memorial nor further acknowledgement of the collapse), with other independent sources and commentaries only from an engineering perspective rather than a political one. I welcome all to review.--ZKang123 (talk) 04:45, 25 January 2024 (UTC)

Image review

 * File:Nicoll_Highway_collapsed_site.png: the unique historic images tag is typically used for cases where the image itself has been the subject of commentary - that doesn't appear to be the case here. Nikkimaria (talk) 06:32, 25 January 2024 (UTC)
 * How should it be retagged, however? Non-free fair use?--ZKang123 (talk) 06:50, 25 January 2024 (UTC)


 * Yep, the generic tag works. Nikkimaria (talk) 22:32, 25 January 2024 (UTC)

Gerald Waldo Luis
Am only able to edit on occassion so apologies for forgetting about your prev FAC lol. Anyway, here are some of my thoughts.


 * So the first three sentences are repetitive: "...leading to the collapse of... The collapse killed... The collapse was caused..." Maybe change the second sentence to "Four workers were killed and three injured"
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)
 * "and the Nicoll Highway"-- rm "the"
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)
 * In the infobox, the line break between the three officials and the LTA guy leaves an empty space as I see it; feels a bit weird. I suppose it's cuz of the "be"?
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)


 * "from the city"-- I don't think 'the city' is accurate wording here? I mean, Singapore is the city. Just writing it as it is ("central business district") should be fine.
 * Rewrote as Singapore's city centre.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)
 * Also suggest linking it to the specific CBD.
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)
 * Link cut-and-cover, marine clay
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)


 * "The missing included a foreman" --> "They included a foreman", just a sentence ago you effectively established you're talking about the missing.
 * Fixed.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)
 * Should kV (kilovolt) be linked?
 * I don't think so, given metre and other measurements aren't linked similarly.--ZKang123 (talk) 07:56, 25 January 2024 (UTC)


 * "After rescuing the three injured people at the site"-- rm "at the site", its repetitive, re: the previous sentence's "at the site."
 * Fixed.--ZKang123 (talk) 09:37, 26 January 2024 (UTC)
 * "he praised the coordination between the SCDF and the Public Utilities Board (PUB) for the ongoing rescue efforts. While initially shocked by the incident, Goh was relieved by the small number of fatalities." --> "he praised the coordination between the SCDF and the Public Utilities Board (PUB) for the ongoing rescue effort, and expressed relief by the small number of fatalities." I don't think "While initially shocked by the incident" adds much; it would be noteworthy if he's not shocked instead.
 * Fixed.--ZKang123 (talk) 09:37, 26 January 2024 (UTC)
 * "and grouting"-- there is a redirect for grouting
 * Fixed.--ZKang123 (talk) 09:37, 26 January 2024 (UTC)
 * "and led to the halting of search operations" --> "and halted the search."
 * Fixed.--ZKang123 (talk) 09:37, 26 January 2024 (UTC)
 * "a grown-up daughter and a son"-- I remember an FA guy telling me this is an example of being specific at one point and ambiguous at another. I don't think the "grown-up" part is needed, especially when the other kids are not specified.
 * Fixed.--ZKang123 (talk) 09:37, 26 January 2024 (UTC)


 * Hi, I was wondering if you felt in a position to either support or oppose this nomination? Obviously, neither is obligatory. Thanks. Gog the Mild (talk) 18:45, 21 February 2024 (UTC)
 * and, really sorry for my late knowledge of this ping, I've been busy IRL and WP notifications often go unnoticed. I see that some have made suggestions, some of which solved some of the comments I was gonna make. My only (minor) suggestion would be to move the "Prime Minister's Office Singapore" and "Channel News Asia" in the citations, from website to pub. Support.  Gerald WL  04:05, 28 February 2024 (UTC)

Reviewing per ZKang's request. I hope I'll have enough time to look thoroughly, will probably focus on criteria 1a/b/c; response times may be longer than usual (time difference + schoolwork) so please ping if I don't reply to something in like >3 days. ~ KN2731 {talk · contribs} 01:51, 9 February 2024 (UTC)

Stuff on first read through:
 * Infobox 15:30 to 3.30 pm for consistency
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * "At the time, the construction project entailed Singapore's most extensive attempt at cut-and-cover excavation in a 40 m (130 ft) layer of soft marine clay." Couple issues: first, specifying the depth of marine clay makes the record sound oddly specific - perhaps move the numbers to the next sentence, since the rest of the geological context is already there; second, "most extensive" gives the impression of horizontal area instead of vertical depth (which I see is what the report asserts) - should probably be reworded
 * I removed the claim and reworded accordingly.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * 'constructed using the "bottom-up" method' - why not simply "constructed from the bottom up"?
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * "Gas supply to the damaged pipe was shut off" - as a result of the damage, or as a precautionary measure after it was noticed that the pipe had been damaged?
 * As a precautionary measure. The source says: "When leaking gas was detected, Power Gas shut off the supply to the severed pipe".--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * 66kV missing a space
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * Check Oxford comma use - I see "a wife, two young children, his mother and nine siblings", also "steel king posts, walers and struts"
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * Speaking of walers - I suppose it's a type of structural beam (and not the horse) - is there anywhere to link that to? Also king post can be linked. I guess a reader has enough context to infer the purpose of these structures, but it'd probably be appreciated to get a link that leads to diagrams or clearer descriptions as to what exactly they are.
 * I have to admit myself, even as a Civil engineering major, that I don't know the purpose of these structures. Neither does Wikipedia have such information.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * Adjust rounding for distance conversions in §Incident, to avoid false precision
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * "expressed relief by" --> "expressed relief at"
 * Fixed.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * "For monitoring purposes, [etc.]" This sentence looks too closely paraphrased for comfort
 * Reworded.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * I was going to ask if the "readings that were still below trigger values at 3 pm" were recorded at exactly 3 pm (which would then need to be written as 3:00 pm), but I see that's Straits Times' issue instead.
 * Check currency rounding (everywhere) - like with the distances, too many significant figures
 * Fixed.---ZKang123 (talk) 03:30, 10 February 2024 (UTC)
 * "Prior to the collapse, [etc.]" maybe this sentence could be split somewhere? I get the information fine, but I think we're in the territory where the lack of commas may be too much for some.
 * Added a semicolon.--ZKang123 (talk) 03:30, 10 February 2024 (UTC)

Made the fixes. Also Happy Year of the Dragon to you!--ZKang123 (talk) 03:30, 10 February 2024 (UTC)


 * Thanks, same to you! Unfortunately studying abroad means I don't get the public holiday and long weekend - I'll hopefully be able to take another look at the prose some time this week. ~ KN2731 {talk · contribs} 01:28, 19 February 2024 (UTC)

Second read through: That should be all I have. ~ KN2731 {talk · contribs} 01:04, 26 February 2024 (UTC)
 * "The CCL tunnels were realigned with Nicoll Highway station, which was rebuilt underneath Republic Avenue south of its original site and was opened on 17 April 2010" - I feel there's something off with the flow here - probably because reading "realigned" gives me the impression that only the tunnels needed to be rebuilt, when the station also needed to be moved? Something like "The CCL tunnels, along with Nicoll Highway station, were rebuilt to the south under Republic Avenue and opened on 17 April 2010" feels less... jarring(?), perhaps.
 * Fixed.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * "To prevent the first span triggering the collapse of the 610-metre (2,000 ft) bridge in case of displacement" - I think "To prevent displacement of the first span triggering the collapse of the 610-metre (2,000 ft) bridge" is clearer, unless I'm misinterpreting something
 * Fixed.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * "Nine SCDF officers [...] were also awarded the Pingat Keberanian" - remove "also" and move the link to Pingat Keberanian (and its definition) up here, it's currently two sentences further down - I suppose this paragraph was rearranged at some point
 * Fixed.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * Link sumps
 * Fixed.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * Rounding again - US$150.7 mil should be US$151 mil, 328 ft should be 330 ft
 * Fixed.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * fixed all of the above.--ZKang123 (talk) 12:34, 26 February 2024 (UTC)
 * Made a couple more changes myself, now comfortable to support on prose. ~ KN2731 {talk · contribs} 01:28, 28 February 2024 (UTC)

MyCat
I'll review once the above comments are addressed, just to make sure I don't duplicate anything already said! MyCatIsAChonk (talk) (not me) (also not me) (still no) 02:15, 10 February 2024 (UTC) , that's all from me, great work. I really like the diagram under "Station relocation and opening"- it's very clear and well-organized. Nice job! MyCatIsAChonk (talk) (not me) (also not me) (still no) 17:24, 10 February 2024 (UTC)
 * - for the lead, I think that clarifying who this is would be helpful: "One of the workers whose body was never recovered, Heng Yeow Peow, was..."
 * Reworded.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * Conversions from foreign currency to USD usually requires a citation- unless the conversion is in the source, add a citation for the conversion
 * Fixed.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - how is the meaning of the name relevant to this article?
 * Well, since it was initially announced as the Kallang Bridge, so I gave further context in its history.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - "Mass Rapid Transit" only needs an article if it's referring to the system- here it seems to be referring to the organization, so I don't believe that "the" is needed
 * It's indeed referring to the MRT system.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - cut hence
 * Fixed.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - switch this around for comprehensibility: "said the rescue efforts should be the priority, rather than apportioning blame."
 * Fixed.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - considering that this event happened in Signapore, I think just "President" would work fine- that is, unless there is some title rule I'm unaware of
 * Fixed. (I think the GOCE editor added that).--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - the rest of the article says "Peow" but this says "Pheow"- is this a typo or a spelling convention?
 * There doesn't seem to be a consistent spelling for this guy; some articles use Peow but others uses Pheow (guess it's a transcription thing). Since the Prime Minister Office use Pheow, I will change accordingly.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - who qualifies as an expert here?
 * Source is rather unclear on this.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * Delink Monosys- the main contractors are not redlinked either, so why link the subcontractor?
 * Fixed.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * In paragraph 3 of "Resumption and conclusion", strut-waler support system is incorrectly linked- fix it with a link similar to the one in the lead
 * Delinked since it has been similarly linked before.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - tense needs to change to past: "A commemorative stone and plaque were erected at the former site marking where they believed Heng was buried, and on every anniversary, workers from Kori Construction visit the site to offer prayers and incense in honour of Heng"
 * Fixed.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)
 * - do the acts have articles, either on English Wikipedia or Singaporean Wikipedia?
 * No, I don't think so.--ZKang123 (talk) 04:06, 12 February 2024 (UTC)


 * Support marvelous work! MyCatIsAChonk (talk) (not me) (also not me) (still no) 20:01, 16 February 2024 (UTC)

Source review by Epicgenius
I will do a source review in a bit.

Note: I was the GA reviewer for this article. As part of the GANR process I reviewed the quality of the sources and spot-checked about 10% of the sources. I recommend that a second source reviewer check this article as well. – Epicgenius (talk) 14:55, 16 February 2024 (UTC)
 * I have not forgotten about this. I plan to do a spot-check on one of every five citations. I will have some formatting comments tomorrow as well. – Epicgenius (talk) 19:24, 3 March 2024 (UTC)

Formatting issues (most of these were already covered at the GA review):
 * I noticed that for some sources, agencies like National Archives of Singapore and Land Transport Directory of Singapore are given in italics. However, since these are not newspapers, magazines, or other works that might normally be italicized, I don't think these need italics.
 * How should these be changed tho? Like, to publisher parameter?
 * I also noticed that some URLs have access dates, while others (mostly for NewspaperSG sources) don't. This is inconsistent even for NewspaperSG sources, as some of these sources do have italics.
 * Fixed. I was initially worried adding access-dates would throw up cs1 issues, but then remembered it was due to url-status=live. Added.
 * In the "Sources" section, the sources should be alphabetized.
 * Fixed

Drive-by comments

 * You consistently avoid using a definite article before "Nicoll Highway". Why? Gog the Mild (talk) 20:39, 8 March 2024 (UTC)
 * I don't know how to answer the question, to be honest. Is it convention to use a definite article when referring to the highway? Local sources don't use the article (e.g. from a government website and local transport authority).--ZKang123 (talk) 01:59, 9 March 2024 (UTC)
 * In so far as the Nicholl Highway is a proper noun, most uses of it require a definite article ('the') to be grammatical in formal English. The rule is explained here.


 * Also, the titles of sources which are not books should be in sentence case, see MOS:TITLECAPS. Gog the Mild (talk) 19:31, 11 March 2024 (UTC)
 * Perhaps this is a WP:ENGVAR thing - I can attest that in Singapore, road names are treated like proper names; I have never seen a definite article used before a road name in Singaporean English, formal or otherwise. ~ KN2731 {talk · contribs} 01:02, 12 March 2024 (UTC)
 * Hmm. Let me check that.
 * TR putting oar in: I'm not sure there is a hard-and-fast rule even in BrE. I can't speak for Singapore English, but in English English the definite article is decidedly negotiable when it comes to thoroughfares and places. I would write "in the King's Road", "along the Strand", "to the Portobello Road", "near the Regent's Park", "at the Philharmonic Hall", "from the Brompton Oratory" etc but many (probably younger) writers would omit the article for some or all of these. –  Tim riley  talk   14:06, 12 March 2024 (UTC)
 * Weell, if Mr riley and the HQ RSs agree, who am I to argue? Gog the Mild (talk) 16:33, 12 March 2024 (UTC)
 * I'm with Tim, I think there is definitely room for manoeuvre. We wouldn't say "the Main Street", for example, and plucking a road FA at random, we wouldn't say the Interstate 90. HJ Mitchell &#124; Penny for your thoughts? 22:00, 18 March 2024 (UTC)
 * May I know which refs specifically which aren't still in title caps? I thought I had converted all of them to titlecaps. Also added the articles for the highway as requested.--ZKang123 (talk) 01:08, 12 March 2024 (UTC)
 * I assume you mean that they are all in title case, which is true. But if the are article titles, eg not book titles, they should be in sentence case. Gog the Mild (talk) 12:38, 12 March 2024 (UTC)
 * Oh wait... I converted all of them to title case instead of sentence case. I misunderstood since previously you said title case in a past FAC...--ZKang123 (talk) 12:54, 12 March 2024 (UTC)
 * I did? Could you pause a moment then, while I check this too. Thanks. Gog the Mild (talk) 16:40, 12 March 2024 (UTC)
 * Well over here, for the North East MRT line.--ZKang123 (talk) 01:25, 13 March 2024 (UTC)

any further updates or feedback?--02:52, 21 March 2024 (UTC)
 * Apologies for the delay, thanks for querying my original comment. After consultations, title case it is.

Harry
I haven't checked sources; this is mostly a prose review —HJ Mitchell &#124; Penny for your thoughts? 23:45, 18 March 2024 (UTC)
 * We generally don't include legal suffixes of companies (eg "LTD"), though the only guidance I can find on that is from the naming conventions for articles rather than the MoS.
 * Well, unless I'm setting up their articles, I will keep them. It's the companies' first mention in the body.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * In 1997, the companies damaged telecommunications company Singtel's underground cables that's quite a confusing sentence as you're explaining what the owner of the subject is before we get to the subject. I'm not sure the ownership is actually relevant so suggest trimming to just "damaged underground cables".
 * Fixed to "damaged underground telecommunications cables".
 * the result of sea level changes in the Kallang River Sea level changes in a river? (Also sea level might need a hyphen as a compound adjective if you're going to use it that way)
 * My mistake. Source did not say Kallang River "Bird et al. (2003) have recently reviewed the age and origins of the Kallang soil deposits based on the history of sea level changes that have occurred during the quaternary period.", but refers more to the sea (Kallang Basin) before the land reclamation.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * Time zone is not normally relevant unless the event straddles time zones or time-zone comparison is necessary (ie, as a Brit, I don't need to know what 3:30 pm in Singapore translates to in my time; the reader just needs to know what time the incident happened in local time because it defines the character of the event).
 * Ok, 3:30pm local time.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * Suggest working the tea break in after you give the time of day. Where it is it appears to imply a connection between the deaths and the tea break.
 * There's some connection, given most of the workers weren't in the site when the incident happened.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * I still think this would be better stated earlier in the paragraph. At the very least, the semicolon needs to be a full stop. As it is, it could be read as one person was found dead because the workers were on a tea break. HJ Mitchell &#124; Penny for your thoughts? 13:46, 19 March 2024 (UTC)
 * Fixed to shift the mention of tea break earlier.--ZKang123 (talk) 14:03, 19 March 2024 (UTC)
 * The collapse disrupted traffic on the highway See Principle of Some Astonishment. Readers can infer that the collapse of a highway will disrupt traffic on said highway.
 * Removed sentence.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * The entire second paragraph of the "Incident" section is very confusing. First you say there was an explosion and fire, then you say the gas was cut off as a precaution (so how did it catch fire?), then you talk about some electricity cables, then you go back to the ?explosion and detail eyewitness reports, but conclude with the LTA denying that there was any explosion. I'm confused. What, if anything, exploded? If the electricity cables aren't relevant to the gas explosion, you should discuss them separately. If the gas was shut off but the explosion was residual gas, mention the shutoff first and explain.
 * Government reports published much later after the collapse tend to conflict with eyewitness and initial reports... Shifted around the facts so that the cables were mentioned first, then the eyewitness reports of fire and explosions.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * Much better. This is purely OR and speculation, but severing high-voltage electricity cables would cause a loud bang and a flash of light which could be what the eyewitnesses thought was an explosion. Of course, we can't say that if the sources don't! <b style="color: teal; font-family: Tahoma">HJ Mitchell</b> &#124; <span style="color: navy; font-family: Times New Roman" title="(Talk page)">Penny for your thoughts? 13:46, 19 March 2024 (UTC)
 * The voltage of the cables doesn't seem relevant and we can infer that they crossed the site otherwise they wouldn't be mentioned.
 * Rewritten.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * Explain (briefly) what the LTA is at first mention.
 * Singapore's transport agency.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * He added the government would investigate the cause through a public inquiry → would convene a public inquiry (or similar adjective); the purpose of an inquiry is obviously to investigate
 * Fixed.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * the search for the foreman Heng Yeow Pheow was called off at 3:30 pm the name needs parenthetical commas if you're using a definite article; you could get away with dropping the "the" and use "foreman" as a false title but that would be less good in my opinion.
 * Fixed.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * I'm not sure the bulleted list of victims complies with WP:NOTMEMORIAL. Their backgrounds and future plans certainly don't seem relevant, and surviving relatives certainly aren't, though their job roles and the circumstances of their deaths/how they were found probably are.
 * Singaporean authorities dismissed terrorism and sabotage as causes of the incident How long did this take?
 * Well, the source is published on the day on the incident, so I say, within a few hours or so.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * The COI called for 143 witnesses to provide evidence, including 14 experts That seems like a low ratio of experts to others. Who were the others? Were they all eyewitnesses/people involved?
 * Seems to be witnesses and other engineers involved.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * The inquiry into the tunnel collapse began on 2 August 2004 We know what the inquiry is investigating, that's what the article is about; and you gave the date immediately above.
 * Fixed and reworded.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * there were "fundamental" design flaw who is this quoting?
 * The article never attributed to anyone.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * It's in quote marks so it needs to be attributed to someone. Or if it can stand on its own, you could remove the quote marks and make the claim in Wikipedia's voice. Or you could just remove the adjective and the quote marks. But you can't have a lingering opinion without telling the reader whose opinion it is. <b style="color: teal; font-family: Tahoma">HJ Mitchell</b> &#124; <span style="color: navy; font-family: Times New Roman" title="(Talk page)">Penny for your thoughts? 13:46, 19 March 2024 (UTC)
 * I rechecked the source and it was the inquiry panel judges who said so.--ZKang123 (talk) 14:03, 19 March 2024 (UTC)
 * More than 170 witnesses were brought in during the 80 days of the inquiry We seem to have gained 27 witnesses but the article does not say where they came from (or much about who they were).
 * Yeah... Tbh I'm not so sure why. Perhaps they just consulted more people.--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * Consider whether naming the criminal defendants is in keeping with WP:BLPNAME


 * Addressed most of the comments, though I'm not so sure about the bullet point names and also the naming of criminal defendants. Thanks for the review!--ZKang123 (talk) 01:36, 19 March 2024 (UTC)
 * After consulting, per WP:NOTMEMORIAL, removed details of surviving relatives, and per WP:BLPNAME, removed direct mentions of personnel convicted.--ZKang123 (talk) 03:15, 19 March 2024 (UTC)
