Feasibility study, function brief, activities, production process of the project.
Site master plan.
Concept of cost plan approved by the Owner.
Phase 2
Design sketch, cost plan based on estimate quantity and proposal materials with approval of the Owner.
Design development, technical standard, detail cost plan with bill of material quantity, construction statement method, construction schedule.
Phase 4
Tender document including: architectural drawing and composition, technical standard, major material list, bill of quantity, construction schedule.
Cost plan submitted to the Owner.
Phase 5
Tender review and tender evaluation, collecting ability Contractors to do the project.
Phase 6
Contract/construction management
Above phases managed, overseen and divided into 2 parts:
A. Design review/management (Phase 1 - Phase 5)
This phase involves the development and examination of selected works with a detailed analysis of its physical, operational and financial aspects to be presented to the Owner for consideration and assessment.
Consider the adequacy of the proposed space requirement and gross space requirements are proposed to each item.
Confirm that all relevant of item’s activities, using process.
Prepare a cost plan having regard to the anticipated budget approved by the Owner. Confirm the appropriateness of the selected development and associated cost plan – Owner approves.
Phase 2 – Schematic design
This phase involves the preparation of design sketches for the agreed development sufficient to permit the preparation and a limit of cost. It applies to both architectural and compositional design and list of used materials.
- Site master plan (1:500) indicating impact on the product process, equipment installation plan.
- Site survey plan (1:500)
- Floor and roof plans for all items (1:100 or 1:200)
- Elevations and sections (1:100 or 1:200)
- Outline specification for all materials and finishes.
- Design options. Life cycle costing, bioclimatic design …
- Development application documents.
This phase involves the ongoing development and correction of approved design, the incorporation of all Authority requirements: design and fire fighting system assessment, environmental effect, building permit.
A further cost plan will be prepared to demonstrate that the project is still within the approved budget.
Typical documentations required at the completion of the stage (including: architecture, composition and substructure, mechanics, electricity) but not necessarily be limited to the following:
Standard perspective images
Site master plan.
Plans, sections and elevations (1:100).
Roof layouts.
Detail architectural drawings: walls, floors, roofs, doors and windows.
Scenery drawing, traffic-way, foot-path, gates, fences, decorative plants…
Drawings of composition: foundation, steel frame and familiar documents
Drainage system
Waste water system and waste water treatment.
Fire fighting system and alarm, lightning conductor.
Lighting system.
Chiller system.
Preliminary specification for all materials and finishes.
Bill of quantity for each item.
Design standard resume.
Construction schedule.
Construction statement method.
Phase 4 – Tender document
This phrase involves in co-ordinate design documents exactly to suit all relevant Authority permits: fire fighting system, environmental effect and construction permit. The project’s documents must have all Authority approvals.
Typical document required at the completion of this stage should include but not necessarily be limited to the following:
Tender’s brief: operation, ability, finance…
Construction contract including special conditions.
Specifications.
Working drawings (architecture, composition and substructure, mechanics, electricity)
Bill of quantity.
Construction time planning/schedule.
A pretender cost plan will be prepared by Design consultant office before the tender document is sent to tender, confirming that the cost of the project is still within the approved budget.
Phase 5 – Tender – tender evaluation and review
This phase involve the calling and evaluation of tenders.
After getting tender, a tender evaluation report and recommendation shall be prepared and submitted to the Owner for approval.
