Tasks
Setting Up Temporary Cutting Station in Apartment Complex Parking Lot
The Dongbu Framing Services team is establishing a temporary cutting station in the Haeundae Beach Residences parking lot. Kim Ji-hoon, the site supervisor, has designated a corner area of the parking lot where they've placed portable folding workbenches. They're setting up a table saw, miter saw, and circular saw stations with dedicated power supplied by their portable generator. Choi Seo-yeon is methodically arranging lumber by type and dimension on wood blocks to keep materials off the ground and organized. Yoon Ji-woo, as safety coordinator, is setting up dust collection systems attached to each saw and placing two industrial fans strategically to blow dust away from the building and occupied areas. He's also establishing a clear workspace perimeter with caution tape and placing safety signage visible to residents. Nguyen Van Minh, despite his fatigue, is carefully unloading their truck and assembling the equipment with practiced efficiency. The team is laying down heavy-duty tarps to catch sawdust and wood scraps, ensuring the parking lot will be easily cleaned at completion.
Assess and document condition of each balcony, creating detailed work plans for each unit
The Dongbu Framing Services team is conducting a comprehensive assessment of all 24 balconies across the 8 apartment units at Haeundae Beach Residences. Kim Ji-hoon leads the inspection process, using a systematic approach to evaluate each balcony's structural integrity, moisture damage, and safety issues. Team members are documenting existing conditions through detailed notes, measurements, and photographs. They're paying particular attention to water damage patterns, rotted wood structures, rusted fasteners, and loose railings. The team is creating detailed diagrams for each balcony, noting differences in dimensions between units and specific repair needs. They're also identifying areas where additional waterproofing is needed to prevent future damage from coastal humidity and saltwater exposure. The documentation includes material quantity estimates for each balcony and notes on access challenges or special tenant considerations. This assessment phase is critical as it identifies potential complications before demolition begins and ensures accurate material ordering for the project.
Remove and dispose of existing damaged railings and flooring while protecting apartment interiors
The crew is methodically removing damaged wooden balcony components from the Haeundae Beach Residences apartments. They begin by laying heavy-duty plastic sheeting and drop cloths in the apartments to protect flooring and furniture near balcony doors. The team is carefully detaching railings by first removing the decorative caps, then unscrewing or cutting through corroded fasteners that secure the railings to the balcony structure. For severely deteriorated sections, they're using reciprocating saws with metal-cutting blades to cut through nails and screws that cannot be removed conventionally. Once railings are detached, they're being carefully lowered to a designated collection area below rather than thrown down, to prevent debris scatter. After the railings, the crew is removing the damaged decking boards, exposing the supporting joists beneath, which are also being inspected for water damage and structural integrity. Any compromised joists are marked for replacement in the next phase. All removed materials are being sorted into separate piles – treated lumber, hardware, and general waste – to comply with local disposal regulations for treated wood. Throughout the process, the workers are maintaining constant communication about structural findings and taking detailed photos of exposed framing to inform the upcoming installation work.
Cut and prepare new treated lumber according to measurements and specifications
The carpentry team is cutting and preparing treated lumber for the balcony renovations. They're working from detailed measurements taken during the assessment phase, creating precise cuts of pressure-treated 2x6 and 2x8 joists, 4x4 posts for structural support, and 2x4s for railing frames. They're applying waterproofing compound to all cut ends to maintain the wood's weather resistance, pre-drilling holes for fasteners in areas where splitting is likely, and grouping materials by balcony unit for efficient installation. The carpenters are carefully following the project specifications which require special considerations for the coastal environment, including using lumber treated to resist salt air corrosion. They're also notching posts and cutting angled joints where needed for proper fitting against the building's exterior walls. Each piece is labeled with its intended location using chalk markings to prevent confusion during installation.
Install New Balcony Floor Framing with Waterproofing and Drainage
This task involves installing new wooden framing structures for apartment balcony floors with proper waterproofing membranes and drainage systems. The work requires precision to ensure the structural integrity while preventing future water damage. The team is carefully placing treated lumber joists at specified intervals, securing them with galvanized hardware, and integrating waterproof membranes that overlap correctly to channel water away from the building. Special attention is paid to creating a slight slope (approximately 2 degrees) away from apartment doors to ensure proper drainage. Team members are using levels constantly to verify proper pitch while ensuring the framing will support the decking material that will be installed later. The waterproofing membrane is being applied with adequate overlaps and sealed at the edges and penetrations. Flashing is installed where the balcony meets the building wall to prevent water intrusion. During installation, workers are communicating frequently about measurements and positioning, double-checking each other's work before permanent attachment.
Constructing and Installing New Balcony Railings
The team is working on manufacturing and installing new railings for the balconies at Haeundae Beach Residences. The workers are carefully measuring and cutting pressure-treated lumber for the railings, ensuring precise dimensions to match the existing balcony structures while improving on the previous design. They're pre-drilling holes to prevent wood splitting and using impact drivers to secure the railings with stainless steel, corrosion-resistant fasteners specifically rated for coastal environments. The railing posts are being installed first, secured firmly to the balcony structure, followed by horizontal support beams and finally the decorative top rails. Workers are wearing safety harnesses as they work on the third-floor balconies. They're installing the railings to meet local building codes requiring railings to be at least 110 cm high with gaps between balusters less than 10 cm to ensure child safety. Special attention is being paid to the corners and connection points to ensure the greatest structural integrity in these high-stress areas. The workers are also applying a water-resistant sealant to all cut ends and joints to extend the lifespan of the wood in the harsh coastal environment.
Balcony Quality Inspection and Testing
The Dongbu Framing team is conducting thorough quality checks on the newly renovated balconies at Haeundae Beach Residences. Kim Ji-hoon leads the inspection process with a detailed checklist, methodically examining all structural elements and connections. They're verifying that all support beams are properly secured with the specified marine-grade fasteners and checking that the railings meet the 120 cm height requirement per local building codes. Each connection point is being tested for stability by applying lateral pressure, while railing posts are individually checked for wobble. The team is using a digital level to ensure proper drainage slopes of 1-2 degrees away from the building to prevent water pooling. They're also pouring small amounts of water at various points to verify drainage path performance. Nguyen is focusing on finish quality, inspecting for any splintered edges, protruding nail heads, or rough surfaces that need sanding. Yoon is documenting all findings with photographs and notes on their quality assurance forms, which will be provided to both management and clients. Any identified issues are marked with blue tape for immediate remediation before the team considers the job complete.
Final Cleanup and Tenant Approval Process
The Dongbu Framing team is conducting the final phase of their balcony renovation contract at Haeundae Beach Residences. Their work involves systematic cleaning of each apartment after completing balcony installations, removing all construction debris, dust, and materials. Team members are carefully protecting interior spaces with drop cloths while using vacuum cleaners with HEPA filters to capture fine wood dust. They're washing exterior glass surfaces that were affected during construction, wiping down all surfaces, and sweeping/mopping floors. The workers are meticulously inspecting balconies for any overlooked items like stray fasteners, tools, or material scraps. After cleaning, Kim Ji-hoon as site supervisor is walking through each unit with tenants, documenting completion with photos, addressing any concerns, and obtaining written approval forms before the team proceeds to the next unit. This thorough approach ensures tenant satisfaction and compliance with the contract requirements for minimal disruption.
