In the old drawing’s margin, eraser marks stood where a room name might have been.
Seorin did not ask for an enlargement. These were formally reproduced records from the original designer’s files. Working drawings retaining pencil marks and plans submitted for filing occupied separate envelopes. First she needed to know which margin she was looking at.
It was the morning of November 17, in the building department’s reading room. The designer’s records officer explained the original comparison and supplied inventory. Seorin had authorized copies concerning the connecting section. The original drawings remained with their custodian.
“Was the erased line a room?” Doun asked.
A line changed during design review, the officer said. The final submitted plan showed a service passage beside it. Erasure did not itself mean somebody had concealed a room on site. Seorin reread the sheet’s heading: DESIGN REVIEW WORKING DRAWING.
The final connecting section sat half a level lower. Stairs and a service passage joined the wings’ different floor heights. Relevant filing confirmations and alteration approvals matched. The strange height was not, by itself, evidence of unauthorized construction.
Seorin found SUSPECTED EXTENSION in her early report. Too much lived inside those words. An authorized extension could later be used differently. Approval at the beginning did not guarantee an unchanged end; a wrong at the end could not erase every initial line.
“This difference in height was within the approved plan.”
The officer indicated the filing number. A number beside a drawing was not enough on its own; the referenced page had to contain the boundary being discussed. Seorin followed it before marking anything confirmed. Only after checking its actual sheet did she close that comparison item. Whether construction followed the approved design required separate completion records.
A reversing vehicle sounded outside. Doun looked up, then back down. To Seorin it recalled work noises beneath the door. But this sound was outside today’s reading room. Nothing connected it to that day.
The next envelope contained completion photographs and filed plans. The officer held the right edge flat. The connecting door opened outward; beyond it lay more space than current photographs showed. Aligning observable column axes and exterior openings brought the records together.
Seorin avoided the changed finish she had wrongly used before. Verified column axes came first. Doun slid transparent paper, then stopped: matching paper edges moved the door too close.
“They’re cropped differently.”
They corrected scale and crop before overlaying them again. Some discrepancies vanished. The present frame and partition still lay beyond the remaining lines. Seorin used different colors for corrected alignment and surviving changes. Time spent positioning the paper entered the work record too.
Repair approval allowed small storage compartments while retaining the passage’s clear width. Dashed lines indicated movable shelving. The present wall resembled that shelving boundary, but its finish continued from floor to above the frame.
“Then the problem was turning shelves into a wall.”
“These records establish a difference between the approval and today’s wall. We still need construction history for who fixed it there, and when.”
She touched the two boundaries in turn. More questions did not diminish today’s difference. They made it possible to state exactly what differed.
The building officer opened a separately obtained enforcement record. During an earlier management period, the department had found that fixed partitions and a changed door swing exceeded approval, and required remedial restoration. Its photographs and location marks matched today’s drawings. This was the responsible department’s finding, not the designer’s speculation.
Seorin read date and scope. It concerned those connecting-section changes, not all construction or every support member’s safety. No completion confirmation for the required remedy accompanied it. The date of a requirement and the state of the building now were different questions. Today’s papers answered the first within a specific area; they did not silently answer the second for every room.
“The requirement was sent, but there’s nothing showing completion?”
Not in the material currently obtained, the officer answered. Possible transfer to another department was being checked. Seorin wrote REMEDIAL-COMPLETION RECORD NOT OBTAINED, rather than REMEDY DEFINITELY NOT CARRIED OUT. The earlier finding that approval had been exceeded remained explicit.
Doun rested a hand on the copied working drawing.
“When I came before, they just called it a storage compartment.”
“Record today who explained it, and when. Don’t turn that into a room that was in the original design.”
He nodded. A name used during his job did not guarantee approval. Seorin did not rewrite herself as somebody who had recognized an unauthorized space immediately. First she had mistaken it for Room 214, then misaligned its finish.
One attached enforcement photograph was folded across the bottom in the reproduction. Doun suggested filling the blank with the neighboring image to make a complete wall. Seorin checked their directions. The apparent same wall showed repairs from different periods.
Could the officer compare that portion with the original again? Their appointment was nearly over. Less repeated viewing elsewhere would leave time for it. Seorin put down two working sheets already read. She chose the obscured portion needed for today’s conclusion over another look at everything.
The supplementary copy showed the whole marked remedial scope. A neighboring room she had suspected was excluded. She moved its question mark into the unresolved list. Narrowing the scope clarified the explanation. The officer and company were actually told why the next task would run late.
During the break, Doun held a paper cup in both hands on a corridor chair. Its picture had six windows. He covered one with a finger.
“Easy to erase in a picture.”
Seorin sat beside him.
“People lived behind the real ones.”
He made no further joke. She did not interpret his silence as the prelude to a confession. They held their cups until the warm water cooled.
In the afternoon, they compared the missing operations-contract attachment’s reference number. The designer’s inventory had a similar title, but it was not the same document. Seorin laid the sheets apart rather than over one another.
The designer’s copy explained the approved boundary. The attachment cited in the implementation schedule appeared to concern later actual use and altered boundaries. Purpose and referenced drawing revisions differed. Today’s inventory supplied no dispatch record showing the designer had delivered that operations attachment.
“So it didn’t disappear here,” Doun said.
“It isn’t in this retained inventory to begin with. We need to check whether it was made elsewhere.”
She removed DISAPPEARED from his wording. Absence from one drawer did not mean a document had passed through every drawer. They had not found the missing paper. Nor had they found evidence that the designer’s office was where it had first been made or last retained. The different purposes and revision references mattered more than similar titles. They had established why it could not be called the original designer’s final plan.
Later operations material cited the authorized extension’s drawing number while apparently using the current boundary already identified as exceeding approval. Under the broad heading of an approved building, a differently configured room had entered. Seorin separated construction, use and operations handover into three periods.
She reported today’s findings and remaining work to her company supervisor. Planned afternoon site photography needed the next authorized access window. The supervisor asked her to coordinate records with structural staff first and avoid duplicate photographs. She did not write a site visit into her log merely because she had visited a records room.
Haeun sent a short message. Had the old passage been built to hide people from the beginning? After agreeing an explanation’s scope with support staff, Seorin called. Haeun was home; first came the sound of adjusting her ankle support.
“The initial extension was an approved service passage. We’ve checked records finding that particular later partition and door alterations exceeded approval.”
“Does that make people who stayed there people in a wrong room?”
Seorin turned toward the drawing. Paper brought to explain a place for people was becoming a question of their wrongdoing again.
“The issue is how the space was altered and operated. It doesn’t erase their presence, or their right to be rescued.”
Haeun understood. This did not mean her mother’s moving date could be public, she added. Seorin confirmed that condition still stood. A new drawing could not reopen the family’s choices automatically.
Back in the reading room, the records officer read the comparison’s first summary: APPROVED DRAWING DIFFERS FROM ILLEGAL SITE. Seorin drew up her chair. ILLEGAL SITE seemed to decide the whole building’s present status.
She separated the approved connecting-section boundary from the particular later changes found to exceed approval. Each source received the period it actually established. The officer nodded over the revision. More words meant the next person could identify what needed checking without seeing every photograph.
Source records returned to their custodians. Seorin’s authorized copies carried scope and provenance lists. The overlay of current photographs and old plans was identified separately as company work. No unmarked transparent sheet entered the next envelope looking like an original design.
That evening came notice from Eungyeong’s side of additional related handover tables. Seorin could not view complete investigation statements, but she could request relevant entries showing who passed on the plans and use areas employed in company work. Management had changed twice before Sero Facilities Management.
All three handover tables in the attachment list contained the same sentence.
EXISTING AREA CONDITIONS FOLLOW THE PREVIOUS CONTRACTOR’S CONFIRMATION.
Seorin placed them in date order. The last company pointed to its predecessor; that company pointed farther back. The first purported confirmation concerned something different from the approved plan found today.
The margin was no longer empty. Three repetitions of the same sentence traced a passage through it: something handed onward without anyone explaining what lay between.
