Building Construction Project 1 Pitch Deck Teardown

Introduction and Team Overview

Slide 1: Title and Contributors

The cover slide identifies the project as "Building Construction Project 1." It lists eight contributors: Wong Teng Chun, Lim Choon Wah, Alexander Chung Siang Yee, Ling Yuan Ming, Jillian Goh Joon Jin, Julia Shen Jaya, Evelyn Sinugroho, and Masoud Ramedani. Each name is accompanied by a numerical ID, likely a student identification number. The slide features a high-resolution photograph of a modern, white three-story residential building with glass balconies. Logos for "SABD" (School of Architecture, Building and Design) and Taylor's University are present, confirming the academic nature of the document.

Site Safety and Equipment

Slide 3: Site and Safety Protocols

Authored by Wong Teng Chun, this slide outlines the legal framework for construction safety in Malaysia. It cites the Department of Occupational Safety and Health (DOSH) and specific legislation: the Occupational Safety and Health Act 1994 (Act 514) and the Factories and Machinery Act 1967 (Act 139). The slide details basic safety equipment, including safety helmets (noting that white is for architects/engineers while yellow/blue is for workers) and safety boots. It also explains the purpose of a project signboard, which must display the address, developer, architect, engineer, contractor, and funders. A photo of a real-world signboard lists the Kuwait Finance House as a funder.

Machinery and External Works

Slide 7: Plants and Machinery

This slide, also by Wong Teng Chun, categorizes the heavy equipment used on-site. It includes photographs and descriptions of a transport truck for excavated materials, a concrete mixer transport truck (explaining the spiral blade mechanism), a portable cement mixer, an excavator for digging trenches, and a hydraulic pile driver. Technical diagrams are provided for the concrete mixer and excavator to label components like the drum, boom cylinder, and bucket.

Slide 11: Earthwork and Settling Out

Ling Yuan Ming covers the initial stages of site preparation. Earthwork is defined as the moving and processing of soil and rock. "Settling out" is described as the process of marking the site to indicate where foundation trenches will be dug. The slide includes an eight-step list for settling out, starting with identifying minimum sizes for foundations and ending with compacting and leveling out concrete. Hand-drawn diagrams illustrate the use of wooden profiles and string lines to ensure the house is built "square."

Slide 15: Water Reticulation

This section details the water supply systems for the site. It distinguishes between temporary water tanks, used to provide clean water for foreign workers and construction purposes, and permanent water tanks. The slide notes that in the Cameron Highlands, tanks are often placed on the ground rather than overhead due to the natural elevation of the hills providing sufficient pressure. Photographs show large blue cylindrical tanks at different stages of the project.

Slide 19: Retaining Wall System

Focusing on the hilly terrain of the Cameron Highlands, this slide explains how soil erosion is prevented. It describes the use of Leucaena seeds planted in horizontal bands 4 to 6 meters apart. The slide states that it takes three to four years for these seeds to grow large enough to fully protect the hillside. Diagrams show the "before" and "after" state of a terraced hillside behind the three-story semi-detached units.

Foundations and Structural Systems

Slide 23: Reinforced Concrete Pile Foundation

Evelyn Sinugroho provides a technical breakdown of the pile cap construction process. The three stages listed are Shuttering and Reinforcing, Setting up Framework, and Pouring in the Concrete. The slide includes detailed engineering drawings (elevation, section, and plan views) of a pile cap, labeling components like the mud slab, reinforcement bars (N1, N2, N3), and the column. On-site photos show the excavation pits and the rebar cages before the concrete pour.

Slide 27: Flooring System

Masoud Ramedani introduces different floor systems, specifically focusing on wood/timber. The slide notes that timber is often used for roofs and top parts of the structure because it is faster to install with simple tools. Hand-drawn sketches illustrate the connection points between wood beams, felt, filling, plywood, and carpet, including the use of steel brackets for structural support.

Superstructure and Formwork

Slide 31 & 35: Formwork, Reinforcement, and Scaffolding

Alexander Chung Siang Yee covers the temporary structures used to support the permanent building. Slide 35 details "Formwork members," specifically the stud pin and wall tie/brace stirrup used to link wall panels together. It describes the installation process where panels are set vertically and locked with bolts. A "stripping tool" is mentioned for dismantling the formwork once the concrete is self-sustaining. A photo shows formwork being applied specifically to construct a pile cap.

Slide 39: Scaffolding Members

This slide identifies the components of the scaffolding system: jet base (with adjustable leveling), inner tube, head (with clamps for metal bars), joint pins for vertical extension, and cross braces for lateral support. The slide uses a combination of sketches and site photos to show how these members form a stable walking surface for workers at height.

Slide 43 & 47: Wall Systems

These slides detail the construction of the building's vertical envelope. Slide 43 shows the transition from the concrete frame to the brick infill. Slide 47 provides a five-stage guide to typical brick erection: cleaning the substrate, applying damp proof concrete (using Sika products), gauging the mortar, laying bricks in a running English order using a mason's line, and removing excessive mortar. It specifically mentions using Sika inside toilet walls to prevent water penetration.

Internal Components and Finishing

Slide 51 & 55: Stairs

Jillian Goh Joon Jin provides an exhaustive look at stairway design. Slide 51 defines terminology such as tread, riser, nosing, stringer, and winders. Slide 55 outlines the "Standard Requirements" dictated by the Department of Standards Malaysia. Key metrics include a minimum tread depth of 11 inches (280mm), a riser height between 4 and 7 inches, and a requirement that landings be at least as wide as the stairway. The slide also notes that doors at landings must not intrude into the required width by more than 7 inches when fully open.

Slide 59: Doors and Windows

Julia Shenjaya categorizes window types used on-site: fixed, casement, awning/hopper, sliding, double-hung, and jalousie. The slide includes a technical diagram of a window frame (head, jamb, sill, casing trim) and photographs of actual installations. It notes that aluminium frames are preferred for being low cost, light weight, and resistant to corrosion and water pressure.

Roofing and Mechanical Services

Slide 63 & 67: Roof Frames and Trusses

Lim Choon Wah details the structural support for the roof. Slide 63 illustrates Gable, Mono Pitch, and Shed roof frames, alongside Triple Howe, Half Truss Mono, and Sloping Flat trusses. Slide 67 provides a detailed anatomy of a truss, labeling the apex, purlins, nail plate, rafters, collar ties, webs, and bottom chords. It explains that the RC (reinforced concrete) wall supports the load of these structures.

Slide 71: Mechanical Services and Workers

The final technical slide covers electrical and plumbing integration. It shows how electrical wires are housed in PVC casings tied to the roof trusses. It also illustrates the ventilation pipe system for waste gases, which must extend through the roof to the exterior. A section on "Workers" describes the physical demands of the job, noting how workers must position their legs on purlins for stability while avoiding applying full force that might cause the thin metal members to bend.

References

Slide 75: Referencing

The deck concludes with a formal list of 12 references. These include academic texts like "A Visual Dictionary of Architecture" by F.D.K. Ching and "Building Construction Handbook" by Chudley and Greeno. It also cites technical product websites for Sika, TH-TRUSS systems, and insulation manufacturers, providing a verifiable trail for the technical claims made throughout the presentation.

What is Missing from this Deck

Market Analysis: There is no mention of the Malaysian real estate market, demand for residential units in Cameron Highlands, or target demographics. · Financial Projections: The deck lacks a budget, cost per square foot, projected sale prices, or an internal rate of return (IRR). · Business Model: There is no information on how the developer intends to monetize the project (e.g., build-to-sell vs. build-to-rent). · Competitive Landscape: No other construction firms or residential developments are mentioned as competitors. · Investment Ask: The deck does not specify an amount of capital being raised or the equity offered in exchange.

What a Founder Should Copy

Technical Granularity: For a hardware or infrastructure startup, the level of detail in the structural diagrams (Slide 23 and 67) is excellent for demonstrating technical feasibility to specialized investors. · Regulatory Compliance: Explicitly citing the relevant laws and standards (Slide 3 and 55) builds immediate credibility and shows the team has performed the necessary due diligence. · Clear Attribution: Assigning specific sections to team members (as seen in the headers of most slides) demonstrates a clear division of labor and individual accountability. · Visual Documentation: The mix of professional photography, on-site progress photos, and hand-drawn technical sketches provides a comprehensive view of the "product" that words alone cannot achieve.
