2.0 Specification

This specification is to clarify how to construct this project and connect all the

materials. This bridge is only built by single and double sticks; connected by glue and

string

Information

Pop sticks: 1.45g each

Cardboard: 130g (approximately)

Maximum bridge self weight: 470 grams

Instruction

The top of the bridge will be constructed with single glued popsticks frame and

double ones for the crossing structure (Figure 2.1). The popsticks will be glued as one on

top others for the single structure to obtain the even surface (Figure 2.2). On the other

hand, the double structure will be glued together as three layers. It is detailed in figure

2.2 with two layers of popsticks with another in between.

For the diagonal section, it is required double structure of popsticks. However, it

will not be glued directly with the linear crossing. The distance between two crossings is

16mm as shown in figure 2.2 and 2.3.

For the triangular supports, it is required the vertical and double structure. String

and glue are used to enhance this structure. Two 8mm holes will be constructed for each

popstick. Then they will be fitted as double horizontal popsticks into others two vertical

components. Finally, they will be tightened by string and glued in between. The

measurement of this structure is given in figure 2.4

This triangular supports is functioned to transfer the load forces into the bridge

abutment. Therefore, it is important to construct this structure with care and accuracy.

3.0 Tender Evaluation Criteria

The tender evaluation criteria are the guidelines for our company to select the

most suitable contractors to practice our designs. The score of 1 has been assigned as the

least impressive performance. The maximum score of 10 will be awarded to the most

efficient company. All criteria will weigh equally. The highest the score is will identify

the preferred company to construct the Bentley Resources Inc project.

Estimated time of Construction/Delivery

As a time-conscious company, the project needs to be built in a limited timeframe.

The estimated time of construction/delivery is very important to confirm the project is

completed punctually. Therefore, the contractor company needs to have the ability to

quickly yet efficiently complete this task. The score will be awarded accordingly to the

company which managed to use lesser time (>3 weeks) and yet successfully constructing

and delivering the bridge.

Contact details

The company convincingly has a clear and working contact details. They can be

easily contacted and required quick replies. The score will be allocated based on the

contacts on the company website (clearly detailed) and how long it probably takes to

reply any inquiries (>1 day contacted).

Experience

A contractor company who has the experience in this project field has the definite

advantage. Experiences are important in order to construct a bridge efficiently as it may

give more confidence to the designer company. It also ensures that the project runs

smoothly as they can understand the design and specification properly. The competency

and qualifications of the contractor will be assessed by how they understand the design

and the specification. Therefore, company who has experienced in understanding and

communication is highly desirable.

Use of Specified Materials

Materials to construct the bridge have to follow according to the list of materials

that have been prepared by the designer company. It is important to follow exactly the

list of material that given by our company to be highly scored. Marks only will be

awarded to the company that is able to meet all of our materials requirements.

Construction and Installation

The methods that use to construct the bridge are vital in ensuring that bridge will

fulfill its required duty. The bridge should be constructing according to the

specifications that provided by our company. Marks will be allocated to the company

that is able to follow the specification without jeopardizing the performance as well as

the quality of the bridge.

Responsibility

The design of the bridge is considered precisely. Tender is strictly required to

pertain to our companys design in order to obtain the exact length and weight of the

bridge. Marks will be given to company that managed to construct the bridge in its

dimensions and weight.


12/15

Professionalism

Professionalism and the organization of the tendering company are mostly

desirable. The tender companys contractors need to communicate with the designers

from the designer company professionally. Moreover, punctually attending meetings

held by the designer company is required. Marks will be awarded to the company that

4.0 Disposal plan

After the bridge has been constructed, the glue between popsticks can be softened

and cleaned by using sand or capacitor oil of the transformer. On the other hand,

composting the popsticks does not seem like a good method. Therefore, an alternative

method needs to be applied to collect and recycle them.

One of the disposal plans is to invent some new items like basket, picture frame,

bookmark, etc. Moreover, they are quite easy to make. As a result, reusing popsticks as a

useful item will be environmental friendly.

Sample for a simple basket is given. This is a simple procedure and can be done

within several steps. Popsticks are prepared with new glue, and a small ice-cream box.

Along the length of the box, some popsticks are glued horizontally. Two or three sticks

are glued vertically along the width. Then we can also set some sticks across the

horizontal ones, which will make the basket nice. Finally, it just takes a few minutes tofinish and the basket need 16 or 18 popsticks in total.

There are also some other designs can be built by popsticks. Overall, we can reuse

these popsticks so that they will not be composted, or littered.

As to cardboard problem, except recycling and reusing them, we can collect then

fold it to combine with the pop sticks to make a pencil holder. Moreover, if we cut the

cardboard as a circle, it can be a tablemat. Furthermore, we can also keep them as mail

packages, or reuse cardboard boxes to store books or magazines, craft material, off-

season clothes, items to donate to charity, or many other household items.
