Position : - Resident Engineer

Duration : - 01.11.2011 – 31.08.2013 (22 months)

During this period I was assigned to handle Provincial roads around the Udunuwara and

Yatinuwara electorates at Kandy District as the Resident Engineer.

Project overview

Project had included 156 (433km) number of Provincial Roads at Kandy District and 19

number of roads at Udunuwara and yatinuwara electorates. Total length of the roads at above

were Correction of base failures, Shoulder construction, preparation of road base using aggregate

base course, Laying of Asphalt wearing coarse, repairing of road structures, Construction of side

drains, Edge line marking and construction of new road structures.

According to the investigation of existing road condition, decided minimum compacted base

course thickness was 100 mm and compaction should not less than 98% of the maximum dry

density of base course. CSS I emulsion was used for primer coat and tact coat at this process

and spread ratio was different at each step. According to specification, bitumen 60-70 was

used for hot mixed asphalt production and weight percentage limit 4.5 to 6.5 for wearing

course and it was vary from 4.2 to 5.5 for binder course.

Necessary laboratory tests were carried out for aggregate samples, bitumen and emulsion

samples and asphalt samples by RDA laboratory and CECB laboratory.

Aggregate tests were Aggregate Impact Value (AIV), Sieve Analysis (SA) and

Diagonal Index.

Bitumen and Emulsion tests were Penetration, Softening Point, Ductility, Specific

Gravity etc.

Tests for asphalt was marshal test.



Gradation distribution of aggregate is very important to achieve optimum compaction of

aggregate base course layer. So proper attention was paid for aggregate supply and random

check was done for aggregate gradation and AIV. Minimum temperature of the laying of hot

mixed asphalt was 135 Co and the compaction of the field should be greater than 98% of

marshal compaction test.

Project overview

This Project was spreaded at nearby area of thalawakele town. Project was consist with

several type buildings such as house buildings, bazaar building, shopping complex, kovil

buildings, school building, work shop, apartment, dormitory and rest house building.

The project was entrusted to CECB as Design and Build contract.

When I was joining the project, more than 75% of the total work has been finished. Out of

seven house buildings at my site, six has come up to foundation level. Structure of the house

buildings consisted of pad foundation, 125 mm thick slab, Asbestos roof on timber frame

work, timber doors and windows and septic tanks and soakage pits with man holes.

Necessary laboratory tests were carried out for coarse aggregate samples such as AIV

(Aggregate Impact Value) and ACV (Aggregate Compact Value), which was proposed to use

for the concrete. After obtaining satisfactory test results, grade 25 manual mixed concrete

used.

12.5mm thick double side film coated marine plywood sheets (8’x 4’) and required types of

timber was used as form work. Acro jacks were used to support beam and slab soffits.

Reinforcements were arranged according to the bar schedules and necessary requirements

were checks when fixing..

Walls were out of block masonry with the external surface plastered to rough finish and the

internal surface to a smooth finish. The external wall surfaces were painted with one coat of

filler and 2 coats of weather shield paint, whilst the internal walls were applied with base

compound and 2 coats of emulsion paint.

The staff of 1 civil engineer assistant, 2 work supervisors, 1 store keeper and trainee

supervisors were assisted me as subordinate staff in the construction works.

Duration :- 15.07.2014 - 15.05.2015 (10 months)

During this period, I was entrusted to carry out steel truss design, concrete structural elements

such as foundations, columns, beams, slabs stair cases of ongoing projects and entire 11

Report on Recognized Training and Responsible Experience


structural design of proposed OPD and Clinic Building at Divisional Hospital Bakamuna.

During this period, I had discussions with Project Architect towards finalizing their working

drawings on general arrangement drawings and layout drawings. Further, I discussed with

Senior Design Engineers on structural member sizing. All the structural elements such as

beams, slabs, columns and staircases were designed and calculations were produced with

relevant drawings.

6.0 MAJOR PROBLEMS ENCOUNTERED

Project : - Ward complex Kandy Hospital

1). Drainage Improvement

Site location was at low level compared to other surrounding building floor levels. Before

starting construction works it was understood during rainy season, site premises will be

flooded. To overcome that problem drainage improvement was done by subsurface drain and

surface drain.

2). Thermal cracks on the raft Foundation

The thickness of the raft foundation beams was 1650mm. Grade 30 ready mix concrete was

used for concreting. Few hours after pouring surface cracks appear on fresh concrete. I

instructed to seal the cracks with cement grout before start curing, but cracks are appeared

even after the curing. Severe cold weather was experienced throughout night until morning

and very hot condition within day time. I understood that crack were merely due to the

sudden rise in ambient temperature. I brought the matter to Senior Engineers attention and

they too confirmed the same. In the mean time, I monitored the results of test cubes and

found that the concrete had gained required strength as per the design.

3). Ground cracks at nearby houses

Proposed building is located at near the hospital boundary line that is connected to highland

village. So excavation was done up to boundary line with narrow slope about 5m height. In

the rainy period some ground cracks appear on top ground of that area near the houses. I

informed to Senior Engineer and final solution was constructing a retaining wall.

4). Difficulties of removal of water that is stagnate in the raft foundation



Heavy rain aroused after the foundation concreting in those days. Therefore, rain water was

accumulated daily in the raft foundation. Due to spreading of Dengue the stagnated water is

needed to remove urgently and it was difficult to remove water daily. I decided to remove the

water daily as much as possible and fill the pits with sand and pebbles temporally till the

rainy season is over.

5). Minimize the lagging of the progress due to rain

Kandy area gets heavy rains during the months of March and April in each year. So I

planned to carry out the interior work of the buildings during this period in order to minimize

the lagging of the progress of the works.

Project : - Road Carpeting Project Kandy

1). Low level of existing man hole

Level of the designed road surface was different at some time from the existing road surface.

This may be caused for the existing man hole located at road surface. Therefore first of all

informed to the relevant authorities about this mater and their responsibilities were

successfully.

2). Segregation of aggregate.

Some field compaction tests were failed for aggregate base course layer in some roads.

Reason for the failure was segregation of base course that happened when transporting and

spreading. This can be avoided by transporting and spreading of wet material. So required

amount of water added to the stock pile and mixed by using JCB machine until uniform

mixture was achived.

Project : - Kotmale Housing Project

1). Incorrect placing of electrical conduit in layout

When checked on the electrical drawings, I noticed that some electrical conduits in slabs

have been placed underneath the bottom R/F net. I decided to lay those conduits over the slab

R/F by considering the importance of 25mm cover



2). Not workable rate for special items

Some detailing of the buildings such as rain water guard, exposed beam took extra

workmanship compared to the normal plastering, painting, etc. Therefore, I studied the

practical situation of these construction and proposed workable rates for such special items.

3). Not available concrete plant

There was no ready mix plant close to this area. So I arranged the slab concreting using three

concrete mixers to operate with two independent gangs.

8.0 CONCLUDING REMARKS

The training received and the responsibilities held with the advice and the guidance of

professionally qualified engineers in above mentioned two organizations have given me a

good experience and the knowledge for handling of any type of civil engineering works.

I take this opportunity to thank them all.

5.3 From June 2013 to December 2013 (6 months)

Design Engineer, Central Engineering Consultancy Bureau

Design Office at Digana

During this period I was entrusted to carry out steel truss design, concrete structural elements

such as foundations, columns, beams, slabs stair cases of ongoing projects and entire

structural design of Professorial building at Batticolo. Building was five storied buildings

with pad footing foundation and walls were out of brick work. During this period, I had

discussions with project Architects towards finalizing their working drawings on general

arrangement drawings and layout drawings. Further, I discussed with Senior Design

Engineers on structural member sizing. All the structural elements such as beams, slabs,

columns, staircases and foundations were designed and calculations were produced with

relevant drawings. The designs were carried out in accordance with the British Standards.



6.0 APPLICATION OF THEORY TO PRACTICE AND INSTANCES OF

TECHNICAL PROBLEMS ENCOUNTERED

6.1 Changes made to the driving process of pre-cast concrete piles.

According to the design, instructions were given to drive pre-cast concrete piles by

using of 2.5 ton hammer. But our construction was carried out during the dry period.

Due to that reason water table within that area was remained at very low level & outer

soil layer of that area became very hard. Therefore pile driving process became difficult

during that period. So we informed our design engineer about the situation & after

having a site visit, he instructed to drive pile after drilling the location with the lower

diameter bit to the required dept.

6.2 Involvement, Attitude, and interferences by medical personnel towards

construction activities

The problem I had to face frequently was negative attitudes and interferences by

medical personnel; especially doctors, matrons and sisters on construction activities. I

often had to work with doctors and other medical personnel. Most of them wanted to

dictate in engineering related decision making and expecting their decisions to be

considered as the final, even though most of them had little idea about engineering. It

was extremely difficult to convince them that the solutions suggested by the Engineers

with regard to their problems were the best possible options. I always discussed the

suggestions of the relevant medical personnel and finalized all decisions at the

estimation stage itself. They however always wanted changes after awarding the

contracts and while commencing the works.



6.3 Cracks in first floor beams of OPD, Clinics, ICU and theater complex

Some hair line cracks were observed in first floor beams after removal of formwork. I soon

started a recording system in which appeared date, location and number according to

propagation pattern. Also thin glass slides were pasted across the cracks to obtain an idea

about crack propagation and in the mean time informed to Project Manager about the matter.

According to their instructions we prepared a comprehensive report regarding matter. Most of

cracks found at mid of beams and intersections with primary and secondary beam. None of

cracks propagated up to slab level.

A group of structural engineers visited the site and their opinion was that none of cracks had

structural impact and hence building was safe. However further investigation such as core

sampling and testing, material property testing etc were carried out to determine the cause of

the cracks. After having several discussions the following conclusions and decisions were

arrived at.

1. None of cracks had structural impact hence the structure was safe and could be used

for the intended purpose but remedial action to be taken to treat the cracks (in order

that reinforcement is protected against corrosion). It was decided to treat the cracks by

epoxy injection method.

2. The nature of the cracks was strongly suggestive that the main cause was the

combination of excessive shrinkage and early thermal movement.

Early thermal movement in concrete occurs due to high temperature in wet concrete probably

due to heated aggregate and reinforcement. Shrinkage occurs due to excessive quantity of

water and insufficient quantity of coarse aggregate. Following site decisions were taken to

overcome the above.

Schedule concreting at night time as far as possible

Use chilled water to mix concrete.25



Use water reducing admixture.
