Located on the campus of Guangzhou Technician College in the Science and Education City of Zengcheng, Guangzhou, this academic lecture hall can host meetings, speeches, performances and even the opening ceremony of a national vocational skills competition final. In its former state, it was an unfinished shell with no professional systems. Today, it is a multifunctional venue integrating stage lighting, professional sound reinforcement, LED display, central control and matrix switching, meeting support systems, and 284 square meters of architectural acoustic treatment.
The project was awarded on August 19, 2024, and passed final acceptance on November 12, 2024. The entire process took approximately three months, including only 45 calendar days of effective on-site construction. Following the sequence of “design development → pre-construction preparation → key construction work → completion → acceptance,” this article reviews the project through 15 on-site photographs and offers a practical reference for schools and project owners planning lecture hall construction.

At first glance, the procurement catalogue describes a goods-purchase project centered on a lighting console. The actual scope, however, included 117 professional stage lights, a five-layer loudspeaker system, and six LED display screens, as well as 284 m² of acoustic renovation, 40 meters of LED strip lighting along the walls and ceiling, decorative wooden slats, a 1-meter extension to the stage steel structure, 46 m² of new steel-structure steps, removal of the first row of steps, widening of the second row to 1.4 meters, and the creation of an observation window opening. Delivering a goods-procurement project according to the logic of an integrated construction project offers the industry its first lesson: a lecture hall is not an equipment showroom. If any link—acoustics, structure, electrical work or decoration—falls short, even the best equipment cannot perform as intended.
Before the project began, the lecture hall had conventional recessed ceiling lights, hard wall finishes with no acoustic treatment, a bare concrete stage, and large, open stepped seating. It had no front-lighting battens, sound reinforcement system or display screens. Speech was difficult to hear during large meetings; performances lacked stage lighting; and presentations had no large-format display. This condition—where completion of the civil works did not mean the venue was ready for use—is common in campus halls and was the starting point for this project.

The design organized the hall’s capabilities into five integrated electromechanical subsystems. The stage lighting system included 117 professional fixtures—profile, soft-light, PAR and moving-head lights—together with a lighting console, dimmer/direct power racks, battens and suspension hardware. The professional sound reinforcement system was configured to meet Grade 1 requirements for multipurpose venues, with five loudspeaker layers: main, auxiliary, stage-lip, monitor and subwoofer systems, plus a digital mixing console and audio matrix. The LED display system comprised five screen types and six physical displays, with a total area of approximately 134.27 m²: a main screen, two side auxiliary screens integrated into angled feature walls, two conference-header screens and an outdoor entrance screen. The central control and matrix system combined a central controller with a seamless HD hybrid matrix to enable one-touch switching among meeting, presentation and performance modes. The meeting support system included 30 double-sided electronic nameplates, cabling for 60 simultaneous interpretation positions, and reserved power and low-voltage infrastructure for recording and live streaming. All five systems were designed, installed and accepted as one coordinated package, avoiding fragmented upgrades such as installing the screen first, adding lighting the following year and sound equipment later.
The sound system’s acoustic gain, sound-field uniformity and speech intelligibility depend heavily on the room’s reverberation time and background noise. Without treating hard wall surfaces, even expensive loudspeakers can produce muddy sound. The familiar industry analogy—“even the best sports car cannot perform on a bad road”—aptly describes the issue. This project included 284 m² of acoustic treatment and associated decoration in the same contract. Sound-absorbing construction was concealed behind sound-transparent wooden slat finishes, allowing mid- and high-frequency sound waves to pass through the grille and reach the absorption layer. This controls reverberation while preserving the appearance of the wood finish. A total of 40 meters of LED strip lighting was also integrated into the ceiling and walls to create layered indirect lighting. Acoustic treatment and interior design were completed as one coordinated solution, avoiding the common compromise of adding acoustic panels only after the interior has been finished.
The design was not considered complete simply because the renderings looked attractive. Measurable, verifiable performance requirements were incorporated into the drawings: main-stage vertical illuminance of at least 1,200 lx; color temperatures of 3,200 K/5,600 K ±150 K; and a color rendering index Ra greater than 85, with a continuous spectrum required. The sound system was checked against five criteria: maximum sound pressure level ≥103 dB, frequency response ±4 dB, acoustic gain ≥−8 dB, sound-field non-uniformity at 1,000 Hz ≤6 dB, and total system noise rating NR-20. The main and auxiliary LED screens required a pixel pitch ≤2.5 mm, refresh rate ≥4,020 Hz and overall resolution of 6,016 × 1,664, together with fanless design, 0 dB(A) noise and compliance with the photobiological safety requirements of IEC TR 62778 and GB/T 20145. These figures were preliminarily checked during design using EASE acoustic simulation and illuminance calculations. Construction then had to turn the design figures into measured test results.
The design stage produced multiple scenario renderings, including meeting, presentation, performance, choir, and executive seating-and-sofa modes. The lighting console included preset scenes and 3D visualization; the digital mixing console supported storage of at least 100 scenes; and the central control matrix supported one-touch power-on and shutdown, including timed power sequencing, via touchscreen, iPad or PC. In daily operation, non-specialist staff can call up “Meeting,” “Presentation” or “Performance” mode with one touch. The 16.28 m² outdoor entrance display was designed and built as part of the same project, giving the hall a visible presence on campus. Multi-mode design is not simply about adding more buttons. It means presetting the lighting, sound, main display and conference-header screen parameters for each scenario so that the entire room can switch modes at the touch of a button. This is the core value of integrated audio, lighting and video delivery.

For a project with a 45-calendar-day construction period, every day spent delaying detailed design is effectively a day lost on site. The detailed design package for this project—including plans, sections, construction details, system diagrams and EASE acoustic simulations—was completed during the tendering stage. After the award on August 19, 2024, the team moved directly to material ordering and site preparation, keeping drawing development outside the construction schedule. For lecture hall projects with tight deadlines, completing detailed design in advance is one of the most effective acceleration measures, yet it is also one of the easiest to overlook.
After mobilization, the project team conducted three technical briefings covering in-conduit wiring, integrated cabling, and LED display acceptance and operation. The in-conduit wiring briefing clarified conduit installation, cable pulling and insulation testing requirements to prevent rework on concealed works. The integrated cabling briefing specified cable selection, installation methods and separation requirements for audio-video and control signals, addressing potential signal interference early. The LED display briefing explained acceptance criteria and daily operating precautions to the school’s management team, ensuring agreement on how the screens would be inspected, operated and maintained before the equipment arrived. These briefings were not formalities; they translated technical standards into practical instructions that installation teams could understand and follow.
The greatest uncertainty in renovating an existing hall lies in conditions that are not shown on the drawings. After entering the site, the team first carried out comprehensive measurements of elevations and grid lines, then checked the detailed design against the actual conditions. Site photographs from early September show that the ceiling light troughs and LED strips had been preliminarily installed and powered on for testing. This created a workable surface for subsequent ceiling closure and fixture suspension, while also confirming the accuracy of the site measurements.
Figure 6. Pre-construction preparation: preliminary installation and power-on testing of ceiling light troughs and LED strips (September 3, 2024)
The construction organization plan identified three major challenges in advance. First, the dimensional accuracy of the angled feature-wall structures: because of their distinctive geometry, deviations in dimensions or angles would directly affect subsequent equipment installation and the overall appearance. Countermeasures included accurate setting-out before construction, clear structural and angular parameters, specialist crews and continuous checks throughout installation. Second, adapting the curved screens: this irregular geometry required high accuracy in substrate flatness and curvature, while edge finishing was difficult. The response was to customize the supporting substrate in advance, pre-layout the screen modules and carefully finish the joints after installation. Third, commissioning multiple equipment systems: the variety and quantity of equipment created a substantial integrated testing workload. A dedicated commissioning plan was therefore prepared, with work divided by system and phase and with clear commissioning milestones and acceptance criteria. Documenting critical challenges before mobilization was essential to avoiding rework during the 45-day schedule.
The display installation was substantial: the main screen covered 62.57 m², auxiliary screens 44.24 m², the two conference-header screens 11.18 m², and the outdoor entrance screen 16.28 m². Supporting structures covered 151.30 m² and included the on-site fabricated steel structures for the angled feature walls. The main challenges were: verifying structural loads and the delivery route for the 15.04-meter-long main screen; controlling module flatness and seam tolerances to ≤0.05 mm; and fitting flexible modules to the curved surfaces of the two angled feature walls, since rigid modules could not achieve the required geometry. Steel structures were prefabricated in the fabrication area, assembled and welded on site, and remeasured section by section. Before installing the flexible modules, the team set out the actual site curvature and determined the bend angle and fixing points for each column, then checked flatness row by row from bottom to top. In early November, the outdoor entrance screen was hoisted into place, bringing the façade’s final illumination closer to completion.

Construction photographs of the audience area clearly show the layers of wall framing and the sound-absorbing substrate. Acoustic treatment and strip lighting followed a defined sequence: mark the ceiling elevation line → install the light trough structure → preliminarily install the LED strips → power-on testing → install the light-box panels → provide maintenance access openings. The wooden slat finish followed a complete process of substrate preparation, setting-out and spacing, panel preparation, U-clip installation, adhesive preparation, slat installation and joint treatment. A sample section was completed and approved before full-scale installation began. The sound-absorbing material was concealed behind the sound-transparent finish, allowing sound waves to pass through the wooden grille and reach the absorption layer. In this way, both reverberation control and the room’s visual appearance were preserved. Since the LED strips and light boxes would require future maintenance, access openings were located before the decorative surfaces were closed. Building maintainability into the construction sequence was key to minimizing future repairs.

This was not a new-build project; work involved demolition and installation within an existing hall. The first row of steps was removed, the second row was widened to 1.4 meters, the stage steel structure was extended by 1 meter, and 46 m² of new steel-structure steps were added. Steelwork followed the sequence of setting-out → cutting materials → installing columns and inter-column bracing → column alignment → connection and fixing → inspection and acceptance. Templates and setting-out rods were prepared at a 1:1 scale. Installation quality complied with the Standard for Quality Acceptance of Steel Structure Engineering (GB 50205). The step finish was installed only after structural acceptance, preventing later structural adjustments from damaging the finished surface. Widening the second row also improved both audience sightlines and passage width—making the renovation an upgrade, not merely a replacement.
Safety was incorporated throughout the stage lighting design. All 117 fixtures were equipped with 146 aluminum hooks and 146 steel-wire safety cables, providing both primary suspension and secondary safety protection. The lighting battens used φ50 steel pipe, treated with anti-corrosion primer and black topcoat. The arrangement included four 12-meter overhead-lighting battens, one 16-meter front-lighting batten and two 4-meter side-lighting battens, with lighting distributed by stage zone. On the power side, the direct power racks provided at least 60 outputs, each rated above 3 kW, using a three-phase, five-wire supply. High-breaking-capacity circuit breakers provided overload and short-circuit protection, together with protection against electric shock if an exposed live conductor became wet. Four DMX signal amplifiers, each configured with one input and eight outputs, isolated the signal circuits to prevent ground-loop interference. The power rack shown in the photograph is the “heart” of the hall’s lighting system.

Eight disciplines—acoustic treatment, decoration, steel structures, lighting, sound reinforcement, LED displays, central control, and power/low-voltage rough-in—were working in the same hall. If one trade blocked the work area, all subsequent work could stop. The project was organized according to the principles of “inside before outside, lower before upper, main structure before secondary components, and prefabrication before installation.” Ceiling strip lighting and wooden slat finishes were completed first to provide working surfaces, after which equipment installation was brought in. Trade coordination followed a defined priority order to resolve clashes among electrical, plumbing, equipment and structural work. Wall chases were cut mechanically to ensure straight routes and consistent depth, with coordination sign-off completed before plastering. Progress was managed through an overall network schedule broken down by month, week and day. Daily coordination meetings resolved immediate obstacles, while weekly meetings reassigned work areas. For a 45-day construction period, schedule risks had to be managed by the day, not merely by the week.
After installation, commissioning proceeded at three levels: individual equipment, subsystem and integrated system. The team successively connected the lighting console and power racks, digital mixing console and loudspeaker system, LED screens and video processors, and central controller and controlled devices. The five sound-system acoustic criteria were included in predictive measurements during integrated commissioning, allowing EQ settings and loudspeaker angles to be adjusted in advance rather than waiting for a third-party report to reveal deficiencies. The central goal was to turn individually capable equipment into a system that was easy to use: one-touch switching among meeting, presentation and performance modes; automatic changeover between primary and backup audio-video signal paths; and batch distribution of names and titles to the 30 double-sided electronic nameplates.
The completion photographs taken on November 13, 2024 show the hall fully expressing the design concept. The main screen is centered, with auxiliary screens wrapping around the two angled feature walls. Above them is an array of fixtures on the front-lighting and overhead-lighting battens. Red upholstered audience seats are paired with light wood finishes, while the wooden grilles and LED strips on the ceiling and walls create clear visual layers. When the conference-header screen lit up, it displayed the words “Guangzhou Saijia Acoustic & Lighting Engineering Co., Ltd. — Proudly Delivered the Lecture Hall of Guangzhou Technician College.” This was the project’s best signature.

The acceptance report for Project No. CZ2024-0891 records that Guangzhou Technician College, the purchasing entity, and Guangzhou Saijia Acoustic & Lighting Engineering Co., Ltd., the supplier, jointly completed project acceptance on November 12, 2024. Overall acceptance was conducted in accordance with applicable national requirements, with a third-party organization invited to participate. The third party’s comments were archived as supporting material for the acceptance certificate, and testing costs were borne by the successful bidder. Delivered products could be randomly selected for testing; if any failed, the entire batch could be rejected. On the acceptance date, the school and inspection personnel examined the displays, stage and audience area item by item on site.

Acceptance means more than checking whether equipment powers on and produces sound. The sound reinforcement system was tested against five Grade 1 multipurpose-venue criteria: maximum sound pressure level ≥103 dB; frequency response from 100–6,300 Hz within −4 dB to +4 dB; acoustic gain ≥−8 dB; steady-state sound-field non-uniformity ≤6 dB at 1,000 Hz and ≤8 dB at 4,000 Hz; and total system noise rating NR-20. Measurements were performed and documented by a third-party organization with nationally recognized qualifications. Stage lighting was checked for main-stage vertical illuminance ≥1,200 lx, color temperature of 3,200 K/5,600 K ±150 K, and Ra >85. LED screens were inspected for brightness, chromaticity uniformity, seams, blue-light hazard, flame retardancy and dielectric strength, among other items. These criteria were incorporated into the design drawings, implemented through construction procedures and measured by a third party at acceptance. Only when a requirement is followed through the entire process is the quality-control loop truly closed.
The project carries a three-year warranty and provides 24/7 on-site support during the warranty period. The contractor commits to responding within two hours after receiving a service request and dispatching engineering technicians to the site within three hours. If a fault cannot be repaired within 24 hours after arrival, spare components or an emergency solution will be provided. If the issue remains unresolved after 48 hours, replacement equipment of the same brand and model will be provided free of charge. If the same item experiences the same fault twice during the warranty period, it will be replaced with a new unit at no cost. For a campus lecture hall that is used frequently and cannot afford downtime, these service commitments are essential.
Photographs dated November 15, 2024 show that only three days after passing acceptance, the hall hosted the opening ceremony of the National Final of the Second National Automotive Repair and Maintenance Service Skills Competition, part of the 2024 National Industry Vocational Skills Competition series. The main and side screens displayed the event’s key visuals in sync, the conference-header screen showed the event theme, and the stage lighting and sound systems operated at full capacity. Less than three months separated the bare hall from its use as the venue for a national competition opening ceremony. This is the value of integrated audio, lighting and video delivery: once the hall is completed, it is ready for use—there is no need to keep adding missing systems while it is already in operation.

First, define acceptance criteria early. Vertical illuminance, the five sound-system criteria, refresh rate and photobiological safety requirements were specified at the design and contract stages; construction then turned those figures into measured reports. Second, deliver acoustics and equipment under the same contract. The 284 m² acoustic renovation was designed and built alongside the five systems, preventing shortcomings in room acoustics from undermining sound-system performance. Third, coordinate multiple trades on a daily basis. During the 45 calendar days, eight disciplines worked in parallel according to the principles of “inside before outside” and “lower before upper,” while daily meetings resolved obstacles. Schools and project owners planning academic lecture halls or multipurpose venue renovations can incorporate these three lessons directly into their next tender documents.
A: Such a project generally includes five subsystems: stage lighting (fixtures, lighting console, power distribution racks, battens and suspension accessories); professional sound reinforcement (digital mixing console, audio processors, loudspeakers, amplifiers and wireless microphones); LED display (main screen, auxiliary screens, conference-header screens, video processors and power distribution); central control and matrix switching (central controller, seamless hybrid matrix and power sequencing); and meeting support (electronic nameplates, simultaneous interpretation, recording/live-streaming cabling and emergency evacuation indicators). Renovations of existing venues should also include architectural acoustic treatment, associated decoration and stage steelwork. The Guangzhou Technician College project integrated sound, lighting, video, displays, control and acoustic/interior renovation into one coordinated delivery.
A: Yes. The key is to design acoustic treatment together with the decorative finish. The absorption layer should be installed behind sound-transparent finishes such as wooden grilles, perforated panels or upholstered surfaces, rather than simply sticking acoustic panels onto a completed wall. This project treated 284 m² of the hall and installed 40 meters of LED strips and wooden slat finishes at the same time, balancing reverberation control with interior appearance. Two points are important: conduits and concealed services must be installed and inspected before the decorative finish is applied; and maintenance access openings must be reserved for internal equipment such as LED strips and light boxes. Otherwise, later maintenance may require dismantling the finish.
A: This project specified main-stage vertical illuminance of at least 1,200 lx, color temperature of 3,200 K/5,600 K ±150 K, and Ra >85, with a continuous spectrum required. Horizontal and vertical illuminance must be distinguished. Cameras capture the front of a person, so facial vertical illuminance determines the quality of the image; high-definition video production generally requires 800–1,500 lux. The 300 lux requirement for a horizontal plane 0.75 meters above the floor in a meeting room under the Standard for Lighting Design of Buildings should not be used to govern stage front lighting. They are entirely different evaluation systems.
A: This project specified fanless screens at the procurement stage, with high-thermal-conductivity silicone pads between the module power supplies and cabinets for passive heat dissipation, achieving 0 dB(A) noise. Photobiological safety was required to comply with IEC TR 62778:2014 and GB/T 20145-2006. The blue-light hazard radiance limit was ≤8.52e−01, classified as exempt/no risk. The screens also required a refresh rate ≥4,020 Hz to avoid flicker in camera recording and live streaming, V-0 flame retardancy, dielectric strength testing at 1,500 V and 3,000 V for one minute each without breakdown or flashover, and MTBF ≥180,000 hours. Since audiences sit close to the screens and remain in the hall for extended periods, all three categories of requirements matter.
A: This project applied five Grade 1 multipurpose-venue acceptance criteria: maximum sound pressure level within the rated passband ≥103 dB; frequency response with the average sound pressure level from 100–6,300 Hz set to 0 dB and a tolerance of −4 dB to +4 dB across the band; average acoustic gain from 125–6,300 Hz ≥−8 dB; steady-state sound-field non-uniformity ≤6 dB at 1,000 Hz and ≤8 dB at 4,000 Hz; and total system noise rating NR-20. Acceptance measurements and reports must be provided by a third-party organization with nationally recognized qualifications. It is advisable to use software such as EASE for simulation during design, followed by predictive measurements and corrective adjustments during commissioning, rather than discovering non-compliance at final acceptance.
A: Yes, but the outcome is largely determined before construction begins. In this project, detailed design was completed during the tendering stage, allowing material ordering and construction to begin immediately after the award. Work areas and overlapping operations were organized according to the principles of inside before outside, lower before upper, main structure before secondary components, and prefabrication before installation. Steel structures and screen supports were prefabricated wherever possible. The schedule was broken down by month, week and day, with daily coordination meetings to remove obstacles. If detailed design and equipment production are not brought forward, schedule risks will concentrate in the installation phase of a 45-day project.
A: Three categories are frequently overlooked. First, power and low-voltage provisions for simultaneous interpretation, recording and live streaming: once decorative finishes are complete, the only options may be exposed cabling or damage to the finish. Second, maintenance access routes and openings inside the lighting battens and ceiling: without them, every maintenance task may require dismantling decorative surfaces. Third, concealed-work inspection records and work-sequence handover forms: third-party acceptance and future maintenance both depend on these records. These items are often the first to be cut when budgets are reduced, even though they can become the most expensive sources of rework later.
Misconception: Purchase equipment only and omit acoustic renovation.
What to do instead: Sound reinforcement performance depends heavily on reverberation time and background noise. In a hard-surfaced hall without acoustic treatment, even high-quality loudspeakers can sound muddy. Include acoustic renovation and equipment procurement in the same contract, and design and construct them together with the decorative finishes—as was done with the 284 m² acoustic treatment in this project.
Misconception: Use general lighting illuminance requirements to specify stage front lighting.
What to do instead: General lighting is evaluated by horizontal illuminance at a plane 0.75 meters above the floor, while stage lighting is evaluated by facial vertical illuminance and color rendering. Technical specifications should state vertical illuminance (for example, ≥1,200 lx), the color-temperature range (3,200 K/5,600 K ±150 K) and the Ra requirement, and should require a continuous spectrum.
Misconception: Select an LED screen based only on pixel pitch.
What to do instead: A lecture hall screen must perform well on camera and operate quietly. In addition to pixel pitch, specify refresh rate (≥1,920 Hz is recommended for filming; this project required ≥4,020 Hz), operating noise (fanless design, 0 dB(A)) and photobiological safety (IEC TR 62778 and GB/T 20145-2006).
Misconception: Compare sound systems only by amplifier power and loudspeaker count.
What to do instead: Power ratings and equipment quantities do not determine actual performance. Acceptance depends on five criteria: maximum sound pressure level, frequency response, acoustic gain, sound-field non-uniformity and total system noise. These should be included in the technical requirements at the procurement stage, together with a requirement for third-party test reports.
Misconception: Consider only the load capacity of lighting battens and omit maintenance and focusing access.
What to do instead: In addition to supporting the fixtures, battens must provide sufficient working space for fixture maintenance, color-filter replacement and focusing. Maintenance openings must also be reserved inside ceiling LED strips and light boxes. If these provisions are omitted during detailed design, each later maintenance task may require dismantling decorative finishes, resulting in significant cost and visual damage.
Misconception: Accept the system merely by checking whether it powers on and produces sound, without third-party testing.
What to do instead: Overall lecture hall acceptance should follow applicable national standards and involve a third-party organization. The sound reinforcement system must be measured and documented by an organization with nationally recognized qualifications. Scheduling third-party testing before formal acceptance leaves time for corrective work within the project period.
