7.0. RA 544: CIVIL ENGINEERING LAW

7.0. RA 544: CIVIL ENGINEERING LAW

Republic Act 544 is an act to regulate the practice of Civil Engineering in the Philippines, which was approved on the 17th of July, 1950. It was amended by RA 1582, which was also approved on the 16th of June 1956.



The version appearing on the PRC site is a condensed version of 5 pages. 



The Act has been re-introduced by Senator Panfilo M. Lacson as Senate Bill no. 2770. The Senator brought to life the Act as he explained that civil engineers are currently confronted with broader issues and they have to integrate the socio-economic and environmental issues with the technical aspects of the construction projects.


"The Civil Engineer is constantly challenged to design and build developments in a manner that is environmentally sound, socially acceptable, and globally competitive."


The Bill sought to achieve the following:


  1. To align the law with the requirements for national development;
  2. To strengthen the profession in facing the formidable challenges resulting from globalization and cross-border practice;
  3. To continuously develop the level of competence of the civil engineers through:
    1. Peer recognition of specialization in civil engineering
    2. Continuing professional development
    3. Strengthening the accredited professional organization of civil engineers
  4. To clearly define the foreign nationalities practice of civil engineering in the country
  5. To promote the growth of the consulting sector by recognizing international philosophy of multi-disciplinary services
  6. To disregard provisions making multi-disciplinary consultancy services difficult, complicated ad impractical
  7. To establish a clear, precise and practical delineation of professional and contractual accountability in the practice in order to serve the law better and protect the public interest

EXAMPLE 1.4.3. HOOP STRESS

A large pipe called a penstock in hydraulic work is 1.5m in diameter. It is composed of wooden staves bound together by steel hoops, each  in cross-sectional area, and is used to conduct water from a reservoir to a powerhouse. If the maximum tensile stress permitted in the hoops is 130MPa, what is the maximum spacing between hoops under a head of water of 30m? (Use mass density of water = .


For one hoop, the FBD shows two F for the hoop against the hydrostatic force caused by pressure.



And the force of the hoops is computed as:





From the FBD, use statics to attain equilibrium (prevent the staves to explode).







where pressure,




So, the required length becomes:



EXAMPLE 1.3.5. COMBINED STRESSES IN A SYSTEM

A steel strut S serving as a brace for a boat hoist transmits a compressive foce P=12kips to the deck of a pier as shown. The strut has a hollow square cross section with wall thickness t= 0.375in. and the angle  between the strut and the horizontal is . A pin through the strut transmits the compressive force from the strut to two gussets G that are welded to the base plate B. Four anchor bolts fasten the base plate to the deck.

The diameter of the pin is , the thickness of the gussets is , the thickness of the base plate is , and the diameter of the anchor bolts is

Determine the following stresses:

  1. The bearing stress  between the strut and the pin,
  2. The shear stress in the pin
  3. The bearing stress between the pin and the gussets
  4. The bearing stress between the anchor bolts and the base plate
  5. The shear stress in the anchor bolts
(Disregard any friction between the base plate and the deck.)


There is only one formula used to solve the stress. The only things considered are the application of the force to the area considered.
                

                   

1. The bearing stress between the strut and the pin.


Check on the plan (b), regardless of the inclination of the strut (any angle applied), the pin will still be acting perpendicular to the strut. Hence, the two parameters are:

load:  

For the area, bearing stress requires the contact area between the strut and the pin. The contact area is the projected area between the two materials.

The contact area is taken as the thickness of the strut and the diameter of the pin.

Hence, 


By using these two parameters:





2. The shear stress in the pin


The pin will have to crack on two points where the strut is applying force.


The shear plane is the cross-sectional area of the pin.





So, with these parameters, the shear stress of the pin can be solved as:



3. The bearing stress between the pin and the gusset



For the bearing stress between the pin and the gussets, the inclination of the load does not matter because of the circular surface of the pin.

The area will be computed as follows:




The bearing stress between the pin and the gussets are solved as:





4. The bearing stress between the anchor bolts and the base plate


In order to solve the bearing stress between the anchor bolts and the base plate, the force applied should cause the contact between the two materials. That contact will occur when the force is applied to the base plate in a manner similar to sliding from the foundation (hence the use of anchor bolts).


For load:




For the area, there are 4 anchor bolts holding the base plate.











Thus, the bearing stress can be solved:





5. The shear stress in the anchor bolts


For the anchor bolt to shear, the cross-section is considered with the applied load parallel to the axis of the base plate.






So, the shear stress becomes:

5.4.1. WHAT IS A "LEVEL OF EFFORT" CONTRACT

A contract termed as "level of effort" is a type that has a procedure similar to cost reimbursement.  This contract requires the following:


  1. A specified level of effort performed over a period of time given by the contractor. This is only through general terms.
  2. The client pays the contractor a fixed amount.
This type of contract is usually negotatiated for study of a specified research or investigation and development area.

Payment under this contract is based on the effort extended and not on the results achieved.

This type of contract is used only when:

  1. There is no definite scope of work defined.
  2. An advance agreement is made on the required level of effort identified.
  3. It is assured that the intended result is impossible to achieve by expending less than the stipulated effort.

5.0 THE SELECTION OF THE CIVIL ENGINEER

The autonomy in the workplace makes the works of a civil engineer unique from others. This chapter discusses recommendations for engineers to be selected.


5.1. BASIS FOR SELECTION


The primary move for a client in selecting an engineer is to define the scope of works in a project. The client determines performance requirements. The following are factors in the selection process for the private sector:

  1. Reputation of the civil engineer as referred by the previous clients.
  2. Validity of registration from PRC.
  3. Qualifications and expertise in performing services.
  4. Ability to assign a qualified staff on site to take charge of the project.
  5. Possession of financial and business resources to accomplish the assignment.
For government projects, EO 164 and PD 1594 as amended apply to procurement of consulting services and selection of contractor for construction.


5.2. CLIENT'S SELECTION COMMITTEE


In big organizations, the person designated to select the civil engineer should be familiar with the project requirements and should be free from pressure - internal or external.

The committee should comprise of three individuals, one of which is a professional civil engineer. The individuals should demonstrate objectivity. Additionally, at least one should be thoroughly familiar with civil engineering practices.


5.3. QUALIFICATIONS-BASED SELECTION (QBS) PROCEDURE


QBS = Qualifications-Based Selection

* If the client has a satisfactory relationship with the civil engineer, there are steps which can be skipped in the procedure.

The procedure is as follows:

1. Statement of: 

  1. General nature of the project.
  2. Services required
  3. Request statements
  4. CE qualifications and experience
  • RFQ. Request for qualifications. Request for general qualifications in a selected area of expertise.
  • RFP.  Request for proposals. Shortlist for selecting a civil engineer for a specific project.
2.Prepare a budget expected from the potential civil engineer.

3. Evaluate statements. Select the best three civil engineers or firms.

4. Correspondence with the chosen engineers. 

   A. Describe the project in detail including:

       a. Scope of the project
       b. Services required

   B. Proposal for the engineer to describe:

       a. Plan for managing
       b. Plan for performing the required services
       c. Assigned personnel
       d. Proposed schedule
       e. Experience with similar projects
       f. Office location where services will be performed
       g. Financial standing
       h. Present workload
       i.  References

* Each civil engineer or firm should be given the opportunity to visit the site, review data and obtain clarification of  any required items.

* For complex projects, a pre-proposal conference might be beneficial.

5. Interview and discussion.

6. Check with recent clients of each engineer about the performance of services.

7. List the engineers of preference.

8. The best qualified engineer is invited to develop a detailed scope.

9. The engineer's proposed compensation should be taken into account.

10. If negotiations fail, inform the first civil engineer or firm through writing about termination  of negotiation and then proceed to the second engineer.

11. When an agreement (scope, schedule, compensation) has been reached, a written contract is finalized. 


5.4. SELECTION PROCEDURE FOR "LEVEL OF EFFORT" CONTRACTS

Bidding may sometimes be unsuitable for the project thus consulting civil engineers opt for level of effort. After furnishing all necessary data, negotiation in this type proceeds like steps 9-11 in QBS system.

5.5. TWO ENVELOP SYSTEM


As its name denotes, two submittals are required in a sealed form. One will contain the technical proposal and the other is the price proposal. The client will then open the technical proposals and checks which is best suited his purpose. After choosing the best technical proposal as he deems fit for the project, he opens the price proposal (second envelop).

The second envelops of those unchosen bidders will then be returned unopened.
