6.5 Construction Principles: Design Requirements, Project Organization, Cost Control, and Value Engineering
Key Takeaways Explain This Topic AI
The National Building Code (PD 1096) requires a building permit before construction, with plans signed and sealed by the responsible licensed professionals.
Earned value analysis compares planned value, earned value and actual cost; CPI = EV/AC and SPI = EV/PV.
A cost performance index below 1.0 means the work is costing more than budgeted for the progress achieved.
Value engineering seeks the required function at the lowest life-cycle cost, with value defined as function divided by cost.
Change orders, requests for information, submittals and daily logs form the documentary record used to settle claims.

6.5 Construction Principles: Design Requirements, Project Organization, Cost Control, and Value Engineering
The AMSTHC TOS area "Construction Principles" has five competencies:
Enumerate general design requirements.
Review the general conditions of the construction contract.
Estimate labor, materials and other quantities.
Design project organization, cost-control procedures and project documentation.
Interpret value engineering analysis models.
Contract documents and Civil Code Articles 1723 and 1724 are covered in Section 1.3, and quantity and cost estimating in Section 6.6. This section covers the rest.
General Design Requirements
Requirement Source What it governs
Building permit, occupancy groups, light and ventilation, setbacks, fire safety in design National Building Code of the Philippines (PD 1096) and its implementing rules Permits, occupancy classification, plan review by the local building official
Structural loads and design National Structural Code of the Philippines (NSCP 2015) Dead, live, wind and seismic loads; concrete, steel, wood and foundation design (Chapters 13–15 of this guide)
- Fire safety Fire Code of the Philippines (RA 9514) Fire protection systems and means of egress
- Accessibility Accessibility Law (BP 344) Ramps, accessible toilets and routes
Plumbing, electrical, mechanical National Plumbing Code; Philippine Electrical Code; Philippine Mechanical Code Building services (Section 6.7)
Professional responsibility RA 544 and other professional laws Plans signed and sealed by the licensed professionals in charge
Design principles across all codes:
Strength: factored loads must not exceed design strength.
Serviceability: limit deflection, cracking and vibration.
Durability: provide cover, coatings and drainage.
Constructability: standardize sizes, repeat forms and avoid congestion.
Economy: minimize life-cycle cost.
General Conditions of the Construction Contract
The general conditions set the rules of the relationship between owner and contractor. Typical clauses:
- Clause Purpose
- Contractor's obligations and site possession Who controls the site and when
- Engineer's or owner's representative Authority to inspect, instruct and certify
Variation (change) orders How changes are ordered and priced; under Civil Code Art. 1724, written authority and a written price are needed
- Time for completion and extensions Excusable delays such as owner changes and force majeure
- Liquidated damages A pre-agreed daily amount for unexcused delay
- Payment, progress billing, retention Monthly billing on measured work; retention held until acceptance
- Performance security and insurance Protects the owner if the contractor defaults
- Defects liability and warranty Contractor corrects defects after completion
- Suspension and termination Grounds and procedures
Dispute resolution Negotiation, then arbitration. The Construction Industry Arbitration Commission (CIAC, under EO 1008) has jurisdiction over construction disputes where the parties agreed to arbitration.
Estimating Labor, Materials and Other Quantities
Materials are taken off from the drawings in standard units (Section 6.6). Allowances are added for waste, laps and breakage.
Labor is estimated from productivity rates , the units of work per crew-day.
Crew-days = Quantity Crew output per day , Labor cost = Crew-days × Crew daily cost \text{Crew-days} = \frac{\text{Quantity}}{\text{Crew output per day}}, \qquad \text{Labor cost} = \text{Crew-days} \times \text{Crew daily cost} Crew-days = Crew output per day Quantity , Labor cost = Crew-days × Crew daily cost
Equipment cost is estimated from rental or ownership-and-operating rates multiplied by the required hours.
Example. A wall needs 240 m 2 240\text{ m}^2 240 m 2 of plastering. A crew of 1 mason and 1 helper plasters 12 m 2 12\text{ m}^2 12 m 2 per day, and the crew costs PHP 1,600 per day. The work takes 240 / 12 = 20 240/12 = 20 240/12 = 20 crew-days, and labor costs 20 × 1,600 = PHP 32,000 20 \times 1{,}600 = \text{PHP }32{,}000 20 × 1 , 600 = PHP 32 , 000 .
Project Organization
- Form Description Strength Weakness
- Functional Staff stay in their departments (design, procurement, field) Technical depth Weak project focus
- Projectized A dedicated team under a project manager Clear authority, fast decisions Duplicated resources
Matrix Staff report to both a functional head and a project manager Shares resources across projects Two bosses; conflict
Typical roles on a building project:
- the owner ;
- the design professionals (architect and engineers of record);
- the construction manager or project manager ;
- the contractor's project engineer and site engineer ;
- foremen and leadmen who direct crews;
- the materials engineer or quality control staff;
the safety officer .
Government projects add a resident engineer who represents the agency.
Cost Control by Earned Value
Earned value management integrates scope, schedule and cost:
- Term Meaning
- PV (planned value) Budgeted cost of work scheduled to date
- EV (earned value) Budgeted cost of work actually performed
- AC (actual cost) Actual cost of work performed
- CV = EV − AC Cost variance; negative means over budget
- SV = EV − PV Schedule variance; negative means behind schedule
- CPI = EV/AC Cost performance index
- SPI = EV/PV Schedule performance index
- EAC = BAC/CPI Estimate at completion if the current cost efficiency continues
Example. The budget at completion (BAC) is PHP 20 million. At month 6, PV = PHP 9.0 million, EV = PHP 8.0 million and AC = PHP 10.0 million.
CPI = 0.80 and SPI = 0.89.
CV = −PHP 2.0 million and SV = −PHP 1.0 million.
EAC = 20/0.80 = PHP 25 million.
The project is over budget and behind schedule. Management should look for cost overruns in specific work items and recover the schedule.
Project Documentation
Daily site logs: weather, manpower, equipment, work done, incidents.
Requests for information (RFIs) and responses.
Shop drawings and submittals with approval status.
Material test results and inspection reports.
Variation orders and extension-of-time requests.
Progress reports and photographs.
Minutes of meetings.
As-built drawings and the punch list at completion.
Good documentation is the evidence used to settle claims and disputes.
Value Engineering
Value engineering (VE) is an organized study of functions to achieve the required performance at the lowest life-cycle cost , without reducing quality or safety:
Value = Function (worth) Cost \text{Value} = \frac{\text{Function (worth)}}{\text{Cost}} Value = Cost Function (worth)
The VE job plan:
Information. Collect costs, requirements and constraints.
Function analysis. Describe each element as a verb plus a noun, for example "support load" or "exclude water." Then identify high-cost, low-worth functions.
Creative. Brainstorm alternatives.
Evaluation. Screen and rank alternatives by weighted criteria and life-cycle cost.
Development. Detail the best proposals with costs and risks.
Presentation and implementation. Recommend changes to the owner.
Example. Replacing a cast-in-place retaining wall with a mechanically stabilized earth wall may provide the same function, retaining fill, at lower cost and shorter duration. VE compares the two on life-cycle cost, which includes maintenance and durability, not just first cost.
